ArcelorMittal Montreal invests CAD27m in the Longueuil bar mill

To strengthen its position as a local producer of high-quality steel, ArcelorMittal Montreal has announced a CAD27m investment to update the finishing line at its Longueuil bar mill. The project, to be completed in 2017, will boost the mill’s production capacity to 500,000 metric tonnes per year and make new added-value products available to customers.

The funding will come from ArcelorMittal’s global capital expenditure fund for strategic projects at its best-performing facilities. “Approval of this investment is a mark of ArcelorMittal senior management’s confidence in our business unit,” said Sujit Sanyal, ArcelorMittal Montreal vice president, operations.

“This is a direct consequence of ongoing improvements in health and safety, quality, productivity and profitability, as well as our good labour relations. These factors have contributed to our past success and are more than ever necessary if we are to continue to stand out from the crowd,” said Luc Lacerte, Longueuil plant manager.

The Longueuil bar mill currently converts about 400,000 tonnes of steel billets per year. They are made into special quality and merchant quality bars, rebar and various other semi-finished products for customers in North America and Mexico. The bar mill is the world’s largest supplier of steel for leaf springs for the major automakers’ light and heavy trucks. The new finishing line will secure additional outlets for billets from the two ArcelorMittal Montreal steelworks in Contrecoeur and will increase the bar mill’s capacity by 100,000 tonnes per year.

Design engineering is currently underway and work on the finishing line will begin in the second quarter of 2016. The new line should be operational by the end of the second quarter of 2017.

The project constitutes an addition to the CAD220m in capital expenditures at ArcelorMittal Montreal facilities in Quebec and Ontario since 2008. Despite the volatile economy, the company is maintaining its position as a world-class Canadian steel producer.

Renewed commitment to Longueuil and the community

The investment will consolidate the 200 jobs at the Longueuil plant, a strategic location for ArcelorMittal Montreal which has been in the municipality’s industrial park since 1974. In 2013, the bar mill underwent a CAD24m upgrade with the installation of a new reheat furnace. That project improved the mill’s performance while reducing its energy consumption and greenhouse gas emissions.

In addition to being a major employer in the area, ArcelorMittal Montreal is committed to the Longueuil community. One example is the company’s support for the sculpture called “La force ouvrière” (the workers’ strength) by Quebec artist Armand Vaillancourt. The colossal work of art is a tribute to union leader Michel Chartrand currently being built in a park bearing Mr. Chartrand’s name in Longueuil. It requires over 500 tonnes of steel, all donated by ArcelorMittal Montreal. Mr. Vaillancourt’s initiative will garner worldwide attention for the City of Longueuil. “Our company has a rich history in Longueuil and our recent decisions show that we are securely anchored here, both economically and culturally”, added Mr. Sanyal.

TOSYALI HOLDING TO BUILD WORLD’S LARGEST DRI COMBO PLANT

June 22, 2015 (Charlotte, NC – USA)   Tosyali Holding has awarded Midrex Technologies, Inc. and its partner Paul Wurth S.A. the project to build the world’s largest multiple product direct reduced iron plant for Tosyali Algeria located in Bethioua (Oran), Algeria.

The new MIDREX NG™ Direct Reduction Plant Combo will be designed to produce 2.5 million tons of DRI and have the capability to vary its production to produce hot direct reduced iron (HDRI) and/or cold direct reduced iron (CDRI) simultaneously without stoppage of production. This new DRI plant will be the largest single DRI plant to produce multiple DRI products in combination.  HDRI will be fed via an Aumund hot transport conveyor to a new EAF meltshop located adjacent to the MIDREX® DRI Plant allowing for greater EAF productivity and energy savings; CDRI can also be produced for additional onsite use.  The new Tosyali Algeria MIDREX® DRI Combo Plant will provide the Tosyali Algeria steelmaking facility with greater production flexibility to produce high quality, low impurity steels as well as decrease their demand for imported scrap.

Benefits of Hot Direct Reduced Iron
There are two main benefits of charging hot DRI (HDRI) to the EAF: lower specific electricity consumption and increased productivity. The energy savings occur because less energy is required in the EAF to heat the DRI to melting temperature, resulting in a shorter overall melting cycle.Additional benefits of charging hot DRI (HDRI) to the EAF are:

Less energy required to heat the DRI to melting temperature.
Shorter overall melting cycle
Reduced electrode consumption
Reduced tap-to-tap time up to 20% compared to charging DRI at ambient temperature.
Reduced electricity consumption about 20 kWh/t liquid steel for each 100° C increase in DRI charging temperature.
Lower overall emissions due to lower electricity demand and reduced need for charge carbon

The history of Tosyalı Holding goes back to 1952. Iskenderun’s first holding, Tosyalı Holding, began a rapid period of growth in the 1980’s. Tosyalı Holding has 16 facilities throughout Turkey with 6 in the Osmaniye Organized Industry Zone (OIZ), 1 in Istanbul, 1 in Izmir, 7 in the Iskenderun OIZ and 1 in the investment stage. Also the company has 2 facilities in the North African country of Algeria and 1 in Europe’s Montenegro. Tosyalı Holding has a total of 18 facilities on 3 continents in 6 different regions along with 12 affiliates. Under the Tosyalı Holding umbrella there are the 3 production companies Tosçelik Profil ve Sac Endüstrisi A.Ş. , Tosyalı Demir Çelik Sanayi A.Ş. and Tosçelik Granül San. A.Ş., which are all leaders in their own sectors, and Tosyalı Dış Ticaret A.Ş., which conducts the foreign trade operations.

SMS Siemag successfully commissions continuous slab caster at Puyang Steel

SMS Siemag Technology (Beijing) Co., Ltd, China,
(www.sms-siemag.com) has successfully put a continuous caster for medium-sized slabs into operation at the Wuan City works of Hebei Puyang Iron and Steel Co., Ltd. (Puyang Steel), China.

Puyang Steel is extending its slab production to include above all high grades, such as peritectic, microalloyed and high-strength steels, high-carbon and boron-alloyed steels, high-quality steels and pipeline grades.

The single-strand continuous slab caster is designed for a yearly production of 1.2 million tons of slabs with thicknesses between 150 and 180 millimeters and widths between 1,000 and 2,300 millimeters. The caster has been prepared for a future retrofit to twin-strand casting (two narrow slabs simultaneously in one strand).

The supply of the continuous casting plant included the complete plant and process technology, as well as X-Pact® electrical and automation systems complete with the technological process models (level 2). The caster is equipped with the technological process models Mold Monitoring System (MMS), Hydraulic Mold Oscillator (HMO), Remote Adjustable Mold (RAM) and dynamic soft reduction. The technology packages make it possible to cast the large variety of steel grades and ensure the manufacture of slabs with high surface and internal quality.

The continuous slab caster was installed in an existing building (brown field). The existing crane systems were retained. Due to the building situation, SMS did not plan a ladle turret, but instead developed a tailor-made ladle car concept. The containment zone has a very small main radius of only 6.5 meters.

The good cooperation with the customer was characterized by straightforwardness, few interfaces and efficient communication.

All this resulted in a steep start-up curve. Already on the fifth production day, 50 heats were cast in one sequence.

“The cooperation with SMS was very positive. The technical know-how impressed us. This was a very good basis for implementing our wishes and demands. This was done in a highly flexible and above all economical way,” says Dr. Cao Liguo, Vice President of Puyang Steel.

Puyang Steel is one of China’s leading private steel makers.

Economic hot strip treatment

Tezcan orders continuous pickling line with acid regeneration plant from SMS Siemag
The Turkish steel service center Tezcan has placed an order with SMS Siemag (www.sms-siemag.com) for the supply of a continuous pickling line. Tezcan will install the line at its Kartepe location near Izmir to improve the economy of its hot strip pickling operations and achieve an increase in output. Especially the high efficiency of the equipment was reason for Tezcan to decide in favor of a continuous pickling line and the turbulence pickling process from SMS Siemag, complete with a connected acid regeneration plant. Starting at the end of 2015, the line will pickle a yearly throughput of 1.3 million tons of hot strip, as a preparatory treatment for the downstream cold rolling and coating processes. Most of the material will be used in the construction industry as galvanized and/or color-coated cold strip.

SMS Siemag will supply the line and its numerous high-capacity components all from a single source, including the mechanical equipment, the process technology as well as the electrical and automation systems. In addition to the design and manufacture of the plant equipment, the supply will also include support during installation and commissioning. This comprehensive service package was a decisive reason for Tezcan to choose SMS Siemag as supplier.

The turbulence pickling technology provides a high-quality descaling result without overpickling. The process is characterized by low energy and acid consumption, low maintenance and operating costs, and long service life of the equipment. These economic, ecological and process-technological benefits convinced Tezcan about the quality of this system.

Hot-rolled low-carbon steel strips will be processed at speeds of up to 220 meters per minute. Strip thicknesses will range between 600 and 1,550 millimeters, strip widths between 1.5 and 5.0 millimeters.

The line will incorporate numerous high-capacity components with convincing performance features in terms of eco-friendliness, economic efficiency, process reliability, flexibility and product quality. A stretch leveler will prepare the strip for the pickling operation in the three downstream pickling tanks. The tanks will be made of plastic materials, facilitating a light-weight design. Each tank will have its own circulation system. A side trimmer with integrated scrap chopper will adjust the desired strip width and straighten the strip edges. In a DUMA-BANDZINK oiling machine, an oil film will be applied to the strip surface in an electrostatic process. A total of two horizontal strip accumulators will be integrated into the line in order to guarantee a continuous strip run.

The pickling acid will be directly processed in the fluidized-bed-type acid regeneration plant supplied by SMS Siemag. The plant will have a capacity to regenerate 7,500 liters hydrochloric acid per hour, enough to cover the line’s complete turnover of pickling liquor. Within a closed circuit, the regenerated liquor will be directly returned to the process and reused for pickling. Additionally, iron oxide will arise as a valuable by-product. This extremely energy-efficient regeneration plant, which complies with all applicable environmental regulations, is an excellent example of a technology effectively combining eco-friendliness and economic efficiency.

Higher capacity and improved product quality

ArcelorMittal has awarded SMS Siemag (www.sms-siemag.com) the order to upgrade the seven-stand hot-wide-strip mill in Gent, Belgium. The order comprises the installation of new finishing stands F1 and F2 as well as modifications to stands F3 and F4. Additionally, the SMS group will support ArcelorMittal in optimizing the rolling process for its third-generation UHSS and AHSS grades.

By this upgrading project, ArcelorMittal is making its Gent hot strip mill fit for future market requirements. With the new equipment, modern actuators and higher rolling forces, ArcelorMittal intends to further improve the quality of its products and expand the portfolio, especially of high-strength and multi-phase grades.

This project continues the close partnership between ArcelorMittal Gent and SMS Siemag. Between 2012 and 2014, SMS Siemag already upgraded the drive trains of finishing stands F1 through F3. That project included the installation of more powerful main and pinion gears as well as SIEFLEX®-HT high-performance spindles. SMS Siemag also supplied a new profile, contour and flatness control system (PCFC) for the mill.

The installation work for this most recent project will take place in two steps during two short mill shutdowns. The modernization concept developed by SMS Siemag will minimize the impact on the running production and the need to adapt the existing equipment. During the first phase, which is scheduled for the end of 2015, stands F3 and F4 will receive new hydraulic screwdown systems, new oil film bearings and additional components that will provide for an increase in rolling forces.

The main project phase in December 2016 will see the installation of the new rolling stands F1 and F2, which will be equipped with high-capacity actuating systems with hydraulic screwdown systems and CVC® plus technology with work-roll shifting and bending. The first stands will feature high rolling forces and torques enabling them to achieve high reduction rates also when rolling high-strength grades. As part of the modernization, the entire finishing mill will receive new loopers.

In order to ensure minimal shutdown times and a fast ramp-up, the two new rolling stands will be pre-assembled and tested in the SMS Siemag workshop in Hilchenbach. On-site erection in Gent will then take place during running production alongside the rolling mill. During the subsequent mill shutdown, the existing stands F1 and F2 will be disassembled and the new, pre-assembled stands will be shifted into the finishing mill in place of the old ones.
