Rerolling Production

Steel processing is represented by rolling shop ( 1050 blooming mill , 550, 325 and 280 section rolling mills), Forging shop, Forging Press shop, forging press department in PM-shop, cold-drawing shop and metal finishing shop.

 Dneprospetsstal is specializing in manufacture of various section rolled stock. Rolling of ingots 3,6-7,4 tons in weight for section mill and production of rolled stock 130-280 mm can be processed on "1050/950" rolling mill. Metal conditioning process is fully mechanized and it is performed on peeling machines of high productivity. Metal products can be delivered with total grinding or in turned condition. In accordance with customer requirements metal product can be US-tested acc. to SEP 1921.

Cold-drawn round bars 2,0 - 45,0 mm in dia, ground and polished bars with size tolerance h9-h11, 1,9-50,0 in dia, hexagonal bars 14-36 mm in dia are produced in the sizing shop.

Bar sizing is performed on chain-driven mills with the force of 15-30 tons, as well as coil-drawing mills. Semi finished rolled stock for sizing is delivered from "325" and "280" rolling mills.

Heat treatment is performed in bell-type gas and electric furnaces using protective atmosphere or in high-frequency heating units. Metal product conditioning is performed on "Kieserling" peeling machines of high productivity.

Large round and square forgings of different steel grades are produced in the forge and press shop. The shop is furnished with hydraulic presses with rated capacity of 60MN and 32MN, equipped with 5- and 10-ton manipulators and US-testing units and "Forster" flow defector for surface imperfection revealing.

The output product range: round and square forgings from 180 up to 550 mm in section (square section - up to 450 mm), flats 120-300 mm in section and disks 400-1100 mm in dia, 120-350 mm in height, 1-6 m in length. The forging shop is intended for production of hard -to-deform alloy tool, high-speed, stainless steel grades, as well as superalloys. Two radial forging machines with rated capacity 10 and 3,4 MN are installed in the shop.

Optimal metal deformation routes allow receiving forgings and semiproduct with high quality of surface performance and corresponding size accuracy. The up-to-date technologies provide high level of automatization and mechanization of forging process. Up to the customer choice surface grinding or peeling can be provided.

The product range: round and square bars 80-200 mm in section, flat bars with dimensions 30-50 x 80-350, as well as billets with irregular section (semiproduct for railway car axles).

In order to improve quality and to increase competitiveness of metal products, DSS is going to erect a new shop for metal finishing where two lines for bar straightening, peeling and polishing will be assembled. Thus, it will be possible to machine bars 12-200 mm in diameter with ISO size tolerance h 9.

Depending on purchaser's request and product type metal products can be delivered in heat-treated condition or without heat treatment. DSS has all corresponding technique facilities to perform heat treatment procedures and to deliver material in annealed, normalized and solution treated condition.
