Structure of production
Production capacity "Zaporizhstal" are:
- Sinter Shop (6 agglomachines),
- Blast furnace (4 blast furnaces),
- Open-hearth furnace (7 open-hearth furnaces and 1 tandem furnaces),
- Preparation plant compositions,
- Crimping shop,
- Workshop hot rolling the thin sheet,
- Cold rolling shop № 1,
- Cold rolling shop № 3.
In sintering shop main plant produced iron ore sinter. Virtually all production processes are automated agglomerate.
Blast furnace smelted annually about 3.5 million tons of pig iron/year. A distinctive feature of iron production MK "Zaporizhstal" is a low content of sulfur and phosphorus.
Production of open-hearth furnace is about 4.0 million tons of steel / year. Hearth furnaces use natural gas. Steel is purged with oxygen and argon. Smelted steel is cast into ingots weighing up to 18.6 tons , which are used for the production of sheet metal.
Shop hot rolling thin sheet produces hot-rolled steel sheets and coils in thicknesses from 2.0 to 8.0 mm. Shop hot rolling thin sheet equipped units to ensure supply of rolled sheets and coils. Continuous sheet mill " 1680 " with a maximum production capacity of 3.7 million tons per year is intended for the production of hot-rolled strip thickness 2.0-8.0 mm, width 860-1500 mm, weighing up to 16 tons roll on three -forming units produced more 500 sizes of cold-formed profiles of carbon and low-alloyed steel with a thickness of 1.0 to 8.0 mm and the width of the scan profile to 1440 mm.
Cold rolling shop number 1 produces cold- rolled flat products in thicknesses from 0.5 to 2.0 mm , width from 850 to 1500 mm in sheets up to 4000 mm in coils weighing up to 16 tons, as well as cold strip thickness from 0.2 to 2.0 mm.
In CHU number 1 on a continuous chetyrehkletevom mill "1680 ", two single-stand reversing mills " 1680 " and " 1200 " and two continuous narrowband chetyrehkletevyh mills , dvadtsativalkovom mill "1700" and two continuous narrowband chetyrehkletevyh mills "450" ??and "650" produced cold rolled carbon and low alloy steel. Shop is equipped with facilities for training , cross-cutting and slitting , ensuring the supply of cold-rolled steel with a thickness of 0.2 to 2.0 mm, width from 10 mm to 1500 mm and a length of 3950 mm to sheet and coils weighing up to 15 tons
Cold rolling shop number 3 on the mill " 2800 " produces cold-rolled sheet with a thickness of 1.5 to 5.0 mm, a width of 1000-2300 mm and lengths up to 3500 mm of carbon steel. The shop has a specialized department for the production of ground and polished sheets and coils. Maximum production capacity for hot-rolled - up to 3.7 million tons, cold-rolled steel - 1.1 million tons, cold-formed profiles - up to 500 thousand tons.
