production divisions



This is one of the first production units in the steelmaking process. Its task is to ensure the supply of metallurgical coke - one of the principal primary materials for making pig iron (hot metal). Coke is produced using the process of dry distillation of black coal in the ovens of the two coking batteries. The by-product of coke production is coke gas, which is cleaned in the Chemicals and Coke-Oven Gas De-sulphurising plants. The separated-out substances go to be used in the chemical industry. 


blast furnaces

These are the part of primary metallurgical production responsible for iron ore materials into molten metal. The three blast furnaces were built in the late 1960's, but have undergone thorough modernization, and in terms of technical equipment and production capacity they currently rank among the most highly-developed in Europe. The U. S. Steel Košice works is the terminus for a broad-gauge railway line coming from Ukraine. Four sintering lines turn the iron ore and additives into sinter, which forms the major part of the charge for each blast furnace. Pig iron is transported in special mobile mixers directly for further processing to the Steel Plants Division. 


steel shops

This is one of the fundamental operations of the integrated steelmaking cycle. Four oxygen converters in the two Steel Plants are responsible for producing a wide range of steels for various areas of application. Apart from the traditionally-produced constructional, deep-drawing and high-tensile steels, the RH-type vacuum degassing plant also enables to produce transformer steel and silicon steel for the electrotechnical industry. Currently 100% of the steel produced here is cast into slabs in two continuous-casting plants.


hot strip mill

This is the first of the finishing operations. Slabs are rolled out on the hot wide-strip 1700 line to make flat rolled products for the world markets. Depending on customer requirements this sheet can be delivered in coils, cut transversely into plates or slit longitudinally into strips. The other part of production serves as the input material for subsequent cold rolling.  

cold strip mill

This is the second finishing plant. The further processing of hot coils by cold rolling produces material not only with considerably reduced thicknesses, but also with mechanical, electromagnetic, surface and other special characteristics for various areas of application. Coils, plates and strips from the Cold Rolling Mill are used in the automobile, engineering and construction industries, and in the manufacture of "white" domestic appliances.



Production of non-grain oriented electrical steel products (for electrical engineering, without and with insulation, they are used for the production of rotating machines, cores of small transformers, solenoids, magnetic circuits and electrical machines), hot-dip galvanized and galvannealed products (from tensile, structural and microalloyed steels, they are suitable for the automotive industry, construction and engineering industry) and organic color coated products (products with organic coatings, with higher oxidation and corrosion resistance are used in construction and in the field of white goods and metal furniture.)
A wide range of products is shipped to customers in packaged coils, bundles or strips.


Tin Mill produces electrolytic tinned coils or plates, which are mainly interested in customers from the food and chemical industries. This extremely thin packaging material is produced from cold-rolled coils. Coils are batch or continuous annealed, skin passed (SR) or double reduced (DR) and countinuously electrocoated. A high-quality product with high added value is shipped to customers in specially packaged coils or bundles.

spiral welded pipes

This operation use hot strip coils produced by U. S. Steel Košice to make spiral-welded pipes.
Hot rolled coiled coils passes through two welding units to make pipes of various diameters, wall thicknesses and lengths, for use by the construction industry in the building of oil, gas and water pipelines.

shipment division

This division provides manipulation, packaging, storage and dispatch of Hot Rolling Mill, Cold Rolling Mill, Coated Products and Tin Mill productions. Finished product for external and internal customers are supplied in coils, sheets or strips. Shipment of those products to customers is implemented by railway, truck or combined transports.



maintain production and distribution of more than twenty different types of energy, especially electrical and heat energy, compressed air, steam, various kinds of water and gas, for example oygen with nitrogen. Aiming for maximum cost reduction the Power workers also make use of metallurgical gases which originate as by-products in the making of coke, iron and steel.


provides services in the areas of rail and road transport to all other divisions and plants, and to co-users of the railway sidings.


performs mechanical and electrical repairs of electrical machines and metallurgical installations, provides a comprehensive service including repairs for lifting equipment. It also does repair scheduling and technical diagnostics of equipment, metrology and servicing of special equipment.


carries out repairs on machines and equipment, including manufacture of components and spare parts. It performs repairs of assemblies and spare parts reconditioning.


New record on HDG Line No. 3

USSK's list of production records was extended last month by the team of employees on Hot-dip Galvanizing Line no. 3 in the Finishing and Tin Mill Division, who managed to achieve a really superb result.
