ArcelorMittal Ostrava Modernizing Medium Section Rolling Mill in Czech Republic
10/06/2014 - ArcelorMittal Ostrava has invested 200 million crowns (US$9.2 million) into the modernization of the medium section rolling mill and has launched production of a unique product branded AMTB (ArcelorMittal threaded bars), designed for the construction sector.
The bars have a special thread along its entire length allowing screwing of nuts and other accessories and the connection of individual parts without the necessity of welding. The bars can be used as reinforcing bars but they can also be used for special applications such as anchoring in the rock or bracing of rock mass bodies. ArcelorMittal Ostrava will be the only domestic producers in the Czech Republic of one of the most common reinforcing and anchoring systems in the world.
“AMTB can be used for civil engineering structures, for driving of underground work and all geotechnical structures like mines, tunnels or underground constructions. As the joints of the bars do not need to be welded or wired together, their installation is faster while saving time and material on construction sites and in mines,” said Tapas Rajderkar, CEO of ArcelorMittal Ostrava.
This solution has been developed thanks to the participation of numerous experts in the area of research and development of metallurgical and mechanical engineering including the specialists from the research and development department of ArcelorMittal Ostrava. The medium section rolling mill will produce AMTB bars in the diameters ranging from 15 mm to 75 mm and lengths from 1 to 24 m. Thanks to the current capex project, the rolling mill will be able to produce even larger diameters and lengths than the dimension range of the existing portfolio of reinforcing bars, which until now has been produced only up to a diameter of 32 mm and lengths up to 15.4 meters.
“In order to improve competitiveness we are focusing on increasing the share of high value added products. Our new product is another step in this direction,” Rajderkar added.
The medium section rolling mill is part of Plant No. 14 – Rolling Mills in ArcelorMittal Ostrava. The length of the rolling train is 1 kilometer. At the time of its birth in 1980, in terms of the amount of the investment, it was the second largest capex project in Czechoslovakia immediately after the Temelín nuclear power plant. The purchase price of the rolling mill was 7 billion Czechoslovak crowns. Today, the rolling mill produces a wide range of hot-rolled long products: fine and medium sections of basic shapes, ribbed reinforcing bars, even-angle bars with dimensions of 40-90mm, U-sections up to the dimension of 120 mm and some special sections. Now it can also produce AMTB with dimensions from 15 to 75 mm.
ArcelorMittal Ostrava a.s. is the largest steelmaker in the Czech Republic and part of the world’s largest steel and mining group ArcelorMittal. It has an annual production capacity of 3 million metric tons of steel. Besides the Czech market, the company sells its products to more than 40 countries around the world. ArcelorMittal Ostrava and its subsidiaries employ more than 7500 people. Average income of its employees amounted to CZK 34,352 in 2013. ArcelorMittal Ostrava produces iron and steel in compliance with all environmental legislation. It conforms to the EU best available techniques (BAT) emission limits that will come into force in 2016. The sole shareholder is ArcelorMittal Holdings A.G.
