The introduction of manufacturing capacity is performed in 4 stages.
1-stage
Push pickling line (PPL): The main purpose of the pickling line is removal of millscales and other surface contaminants from the surface of hot-rolled steel strip. The design capacity of the line is 500 thousand tons of pickled steel per year, with the projected capacity development potential up to 750 thousand tons per year. Pickling of hot-rolled products is carried out by "Turboflo" technology, which ensures more effective pickling and higher productivity with lower energy consumption due to the high turbulence of pickling solution, water traps between the baths and special design of the pickling bath covers. The maximum speed is 150 m/min. The width of the specified hot-rolled strip is from 800 to 1300 mm, thickness from 2.2 to 5.0 mm.
2-stage
Reverse cold rolling mill (RCRM). Production of cold-rolled strips, namely reduction of thickness of pickled hot-rolled steel, is carried out on reversible two-stand quarterly cold-rolling mill "DANIELI" (Italy) with the designed production capacity of 500 thousand tons per year and with the possibility of increasing production up to 750 thousand tons of cold-rolled steel per year, providing strip thickness compression. During the rolling process in automatic mode is controlled: strip thickness by three sensors (thickness gauge) of X-ray radiation; strip profile (flatness) by means of two profilometer rollers. Cold-rolled steel is one of the most demanded types of rolled steel products.
3-stage
The continuous hot dip galvanizing line is designed for continuous thermal-chemical treatment of cold-rolled galvanized strip after rolling and bilateral application of zinc melt on the surface of the steel strip, which provides reliable protection of the steel against corrosion. Hot dip galvanizing by the method of continuous immersion of cold-rolled steel strip in zinc melt is performed on Danieli equipment (Italy) with a capacity of 500 thousand tons of galvanized steel per year. The cold-rolled strip, which is a roll for the galvanizing line, is 0.29 to 1.2 mm thick, 800 to 1250 mm wide, processing speed 210 m/min, coil weight varies from 10 to 30 tons.
