H.E.S issues Primetals Technologies with final acceptance for modernized bar mill

  • New rolling stands without housing improve product tolerances
  • Larger roll barrels increase stability and allow multi-strand operation
  • Faster roll change and production start-up

H.E.S. Hennigsdorfer Elektrostahlwerke GmbH (H.E.S), a company in the Riva Group, has issued Primetals Technologies with the final acceptance certificate for a modernized, turnkey bar mill in Hennigsdorf, in the German state of Brandenburg. The modernization project included replacing two existing stands in the roughing mill with new Red Ring stands, which do not have housing. This solution requires less space and has greater rigidity to enable consistently narrow product tolerances to be achieved. The new stands also have larger rolls. This increases the stability of the process and allows multi-strand operation. Primetals Technologies had received the order in May 2015, and commissioning took place during a scheduled plant shutdown at the turn of the year 2015/16 with industrial rolling restored on January 2.

H.E.S. is one of three production locations that the Italian Riva Group has in Germany. The plant converts raw scrap metal provided by Riva Stahl GmbH into steel products, which are then marketed by Riva Stahl GmbH. The range of products includes continuously cast billets, reinforcement steel, and bright steel, which is mainly supplied to the automotive industry and its suppliers.

For the modernization of the bar mill, Primetals Technologies supplied two new type RR564 housingless Red Ring roughing stands with a horizontal configuration. The scope of supply also included couplings, drive spindles and spindle supports. The center line of the rolls can be varied between 480 and 730 millimeters. The roll barrels are 850 millimeters long. A new gear box was also installed on one stand. Stand change parts, a motorized device for roll change operation, and the on-board electrical equipment for the stands completed the scope of supply. Primetals Technologies was also responsible for construction and commissioning.

The bar mill processes billets of carbon steel and low alloy grades with a square cross-sectional area of 140 x 140 millimeters, a length of 12 meters, and a weight of 1.8 metric tons. The final products are rebars with diameters of between 10 and 50 millimeters, and rounds with diameters ranging from 14 to 50 millimeters. The plant can also be run in two-slit mode if the finished products have a diameter of 28 millimeters or less.

Red Ring is a registered trademark of Primetals Technologies in some countries.

CANADIAN STEEL PRICE ROUNDUP FROM MEPS INTERNATIONAL LTD

Canadian hot rolled coil selling figures held relatively firm in August, according to MEPS. Customers continue to purchase for their immediate needs. There are mixed expectations for future sales. Mills believe that transaction values will move up in the short term. In contrast, service centres are sceptical that any increase will prove possible.

Commodity plate transaction values have plummeted since the fourth quarter of last year. Consumption by the energy and mining segments has deteriorated due to the drop in prices for oil and metals. Imports and short mill lead times are exerting negative pressure on domestic figures. Service centres report low resale margins.

Prices for cold rolled coil declined sharply in the first quarter of this year and beginning of the second trimester. This was due to import pressure and a reduction in steelmaking raw material costs. More recently, the threat from overseas suppliers has eased, somewhat. Despite this, the local mills are looking for orders.

Conditions remain quiet in the wire rod sector. Participants note a lack of direction in the marketplace. Transaction values have been static over the last few months.
Rebar selling figures continued to slip in August. Purchasing is being undertaken for immediate requirements only. There is competition from overseas suppliers.

Danieli to supply second MiDa (MicroMillDanieli with endless casting and rolling technology) to CMC (USA).

This new mill in Oklahoma will mirror CMC’s existing Micro-Mill in Mesa, Arizona and will be built with improved technology deriving from Danieli’s and CMC’s operating experience with the world’s first Micro-Mill, which Danieli and CMC successfully commissioned in Arizona in late 2009.

Similarly to the Arizona mill, the New Micro-Mill will consist of:
› a system for the continuous feeding of the scrap into the electric arc furnace;
› a AC electric arc furnace equipped with the most advanced technological packages for automatic and safe operations;
› a ladle furnace with double ladle, ladle lifting and automatic inert gas hook-up for faster cycles and safer operation;
› alloy system;
› fume treatment plant;
› a single-strand continuous casting machine;
› induction furnace for billet temperature equalization prior to entering the rolling mill;
› a continuous horizontal/vertical rolling mill;
› a system for quenching and tempering of all rebar product to greatly reduce alloy usage in the meltshop;
› an ultra-compact finishing end system for the cutting of rebar product to any desired finished length directly off the last finishing stand;
› a wire tying machines;
› bundle collecting and finishing facilities.

Danieli Automation will supply the complete electrical package including an innovative automation system for data analysis and reporting while Danieli Service will provide the Danieli Maintenance Management System (DMMS) package, where preventive maintenance, spare parts, personnel, equipment costs and fault analysis are managed through an integrated system.

The addition of a second Danieli Micro-Mill to CMC’s portfolio of highly efficient, customer focused and cost effective steel production facilities will enhance CMC’s position as a leading supplier of long products in the U.S. market.

Joe Alvarado, Chairman, President and CEO of CMC, said: “The location of the mill in Durant, Oklahoma, 80 miles north of Dallas, Texas, will allow us to better serve a growing North Texas market as well as expand into markets in Oklahoma, Kansas, Nebraska, Arkansas and Missouri. The facility will produce low cost, high quality steel products, which will complement our existing manufacturing capability to better serve our customers.   This new micro mill will also complement CMC’s existing recycling and fabrication footprint, enhancing CMC’s ability to further leverage our raw material supply chain and optimize product mix within our existing operations.”

MIDA-Micromill Danieli concept is a low-capacity steel plant for regional markets that, thanks to its innovative technological solutions, can compete in term of CapEx and OpEx with steel plants with much higher capacity.

The Oklahoma micro-mill is expected to be commissioned in fall of 2017.

MEPS GLOBAL STEEL PRICE HITS SIX MONTH LOW IN NOVEMBER

According to MEPS, despite relatively healthy demand, US flat product transaction values have continued to slip over the last month, mainly as a result of cheaper raw materials and import pressure. High prices in North America have attracted a great deal of interest from steelmakers elsewhere in the world. Imports are at historically high levels. Domestic mill delivery lead times have shortened. Service centres report that sales have already slowed as we head into December. Their inventories are adequate to high. However, they are anticipating robust demand in 2015, with many projects about to come on stream.

There has been some softening in the Canadian market for seasonal reasons. Mill delivery lead times are reducing. Import volumes are on the rise. There has been some marginal price erosion but producers are trying hard to resist further downward movements. Recent mill price rise announcements are viewed as a tactic to keep transaction numbers stable.

Chinese manufacturing growth continues to slow, leading to weaker domestic steel demand at the same time as supply increases and the producers’ raw material costs tumble. Market players are pessimistic about the future direction of steel prices. Overseas sales volumes hit record highs in October. However, increasing anti-dumping and anti-subsidy measures against Chinese steel products could hinder future developments, as could the speculation regarding the removal of VAT rebates on exports.

The Japanese economy slipped back into recession in the third quarter. September statistics show that steel orders dropped by 2.8 percent, year-on-year. Exports are weak. Domestic demand was relatively stable. Flat product values were all revised downwards in November, reflecting fierce import competition, especially from China and South Korea. Tokyo Steel has decided to keep official list prices for December deliveries unchanged from the previous month. The company cited an imbalance in supply and demand. Inventories stood at a thirteen year high at the end of September. Moreover, the rapidly declining yen is making imported raw materials more expensive for the producer.

Steel output continues to climb in South Korea as more new capacity comes on stream. Local estimates suggest that annual production will reach a record high by the end of the year. However, domestic mills continue to struggle with significant import pressure and slowing economic growth. Chinese and Japanese steelmakers are gaining market share. Local mills continue to reduce transaction values in an effort to compete.

The overall Taiwanese economic outlook is said to be moderately optimistic. However, major integrated steelmaker, CSC, has decided to cut domestic list prices for the January/February 2015 period by an average of 1.7 percent, compared with figures for December contracts. Demand in the home market has weakened as downstream mills and finished goods manufacturers are facing increased competition in export markets as the Japanese yen and South Korean won devalue against the US dollar. Moreover, iron ore costs are declining.

Polish activity has improved slightly but service centres are expecting it to slow in December for seasonal reasons. The mills have failed to lift prices in euro terms but exchange rate fluctuations have pushed up selling figures when measured in zlotys. Czech/Slovak prices have hardly changed on a euro basis. Economic forecasts have recently been revised in the Czech Republic and, although there are some optimistic signals, overall expectations are a little lower than previously estimated.

West European flat product prices remain under negative pressure due to domestic oversupply, weakening raw material costs and flat demand caused by poor macro-economic conditions in several nations. Third country imports are unattractive as local offers are at similar prices, with shorter delivery lead times.

CHINESE STEEL LOSING SOME OF ITS COMPETITIVE EDGE – MEPS

UK steel industry analysts, MEPS, reports that, in October, a profound change developed in the relationship between Chinese export steel prices and domestic selling values in the rest of the world.

According to the company’s latest report, CHINA STEEL REVIEW, Chinese exporters lowered their steel prices last month for most rolled steel products. The median reduction was US$13 per tonne. However, average domestic selling figures in North America decreased by US$17 per tonne in the same period. Local average steel selling values in the European Union decreased by US$27 per tonne and those in East Asia fell by US$35 in October.

The differential between Chinese export delivered prices and domestic selling values is a key item in the decision making process to purchase from China. Improved quality from Chinese mills has also, however, played its part.

It is possible that, in the near future, China’s steel products could become less attractive to buyers in the industrialised countries of the world, particularly, if their steel market conditions deteriorate further.

Total Chinese exports of all steel products, including tubes and semi-finished goods, totalled 51.54 million tonnes in the first eight months of this year. This represents an increase of 36 percent on the outturn in 2013. Foreign supplies of the nine finished rolled steel mill products, which had not undergone further processing, were recorded at 44.2 million tonnes – up by almost 45 percent in the same period.

The most popular finished rolled steel products for export remain hot rolled coil, wire rod and merchant bar. Statistics for the latter item are dubious, because it is widely believed that a proportion of billet sales were recorded as merchant bar in the official documentation to avoid export taxes. The tonnage sold under the banner of merchant bar has increased by approximately 75 percent so far this year. This figure is almost double the average increase for all the other products.

The Chinese mills were able to lift their sales volumes of rolled steel products because of their ability to compete on price with other manufacturers around the world. This developed despite the cost of freight and extended period of time for delivery. A change to this situation may be on the horizon. Chinese steel exports may decline in 2015. Watch this space.
