Small revamps, big results

ArcelorMittal South Africa orders Continuous Pickling Line revamp from Danieli Service

ArcelorMittal has contracted Danieli Service to refurbish and revamp the notchers installed along pickling line #3 at the Vanderbijlpark Works, in South Africa.

The scope of work centers on installing a new Danieli notcher at the CPL delivery side and refurbishing the existing notcher, which be relocated to the CPL entry area. (The original notchers are of Wean Industries design, now part of the Danieli Wean United portfolio).

Special knives featuring DanCut technology for accurate edge cutting of ultra-high steel grades strip will be the core items of both notchers.

Custom-designed hydraulic power units provided by Danieli Hydraulics and process control integration provided by Danieli Automation will complete the CPL upgrade.

The first stage of the project is scheduled for completion at the end of the 2017, followed by second and final stage in June 2018.

Improved notching performance will result in reduced time cycle, optimized strip-cutting stress and higher-strength cutting capability.

In addition to the mechanical supply Danieli will provide erection, commissioning, and advisory services through its specialized plant upgrade team.

International Steels Limited (ISL) orders second Compact Cold Mill from SMS group

In February 2017, Pakistani cold strip producer International Steels Limited (ISL) placed an order with SMS group for the full-line supply of a twin-stand CCM® (Compact Cold Mill) in four-high design.In the course of the systematic expansion of its production facilities, ISL trusts one more time in flexible and reliable SMS group technology. Since 2011, the Pakistani cold strip producer, located in Karachi, has been operating a reversing cold mill from SMS group. In 2015, the mill was extended into a twin-stand CCM®. The second CCM® will be installed in a new building adjacent to the existing one. The current annual cold strip capacity of 450,000 tons will be increased to 900,000 tons in total. The new CCM® is scheduled to go into production as early as in summer 2018.

The new reversing cold mill will be designed for rolling carbon steel strips in widths of up to 1,250 millimeters with final gages down to 0.15 millimeters. The strips will be rolled at speeds of up to 1,200 meters per minute using very thin work rolls. These rolls, with minimum diameters of 300 millimeters, will achieve high pass reductions and efficient plant operation.

Like in the case of the previously installed plants, SMS group will supply the quality determining components such as the mill stands and drive trains from Germany. The two mill stands in four-high design will come with CVC®plus technology in combination with negative and positive work roll bending and two X-Shape flatness measuring rolls. Of the latter, one will be installed in the entry and one in the exit section of the CCM®. In addition, provision will be made for ISL to retrofit a multizone cooling system in the future, in order to be able to meet any further increasing strip quality requirements, especially in terms of strip flatness. Various features, such as the equipment for quick work roll changes, will make for high productivity.

ISL puts special emphasis on SMS group’s supplying the complete mechatronic equipment from a single source. This will guarantee smooth interaction between the mechanical equipment and the X-Pact® electrical and automation systems. The automation system will cover level 1 including the controls for all rolling mill functions as well as level 2 complete with pass schedule calculation. To ensure highest strip quality, the scope of X-Pact® supplies will include the latest of measuring technology.

SMS group will also supply the media systems including the emulsion plant, the high and low pressure hydraulic systems and the fume exhaust system.

The SMS group is a group of companies internationally active in plant construction and mechanical engineering for the steel and nonferrous metals industry. Its 14,000 employees generate sales of over EUR 3.3 bn.

GLOBAL STAINLESS STEEL OUTPUT TO EXPAND IN 2017 TO NEW RECORD HIGH – MEPS

Worldwide crude stainless steel production, in 2016, reached an all-time high total of nearly 45.8 million tonnes. This represents an increase of more than 10 percent, compared with the year earlier figure. MEPS predicts that global output will grow by around 3.75 percent, in 2017, to achieve a new record high mark of around 47.5 million tonnes.

Outturn in all of the long-established stainless steelmaking countries increased, year-on-year, in 2016, after most had recorded a contraction in the previous twelve months. Production continued to grow, strongly, in China and in the developing nations.

Despite earlier expectations that stainless steel output growth, in China, would slow down, rapid expansion continued, in 2016. The country’s official annual total was reported at nearly 25 million tonnes – an increase of more than 15 percent, compared with the previous year. This equates to almost 55 percent of the world aggregate figure. With antidumping measures, in many countries, restricting global exports, China has recently made moves to curb its rate of expansion.

After a slight dip, in 2015, production in the United States returned to its trend of robust growth, increasing by more than 6 percent, last year, to total around 2.5 million tonnes. MEPS predicts that output will expand by a further 2 percent, in 2017.

Crude stainless steel production recovered strongly, in Taiwan, in 2016 – increasing by almost 14 percent, year-on-year, to exceed 1.25 million tonnes, for the first time since 2010. More moderate growth is forecast for this year.

Annual outturn advanced by between one and two percent, in the EU, Japan and South Korea, last year. Further, steady expansion, of a similar magnitude, is foreseen, in these markets, in 2017.
