Slabs move to the hot rolling mill, are heated up to 1280 degrees centigrade in preheating furnaces, are descaled and undergo early stages of rolling. In this unit, the coils are narrowed down to 1.2 -16 millimeters in thickness and rolled into coils.
Hot-rolled coil with the following dimensions
1.Thickness from 1.2 to 16 millimeters
2.Width from 650 to 1850 millimeters
3.Packaged (gross) weight: from 5 to 30 tons
Details of the structural and special steel products appear in the product specifications handbook.
Surface quality: black steel with the smoothness below IU-85
Hot rolling mill’s finishing lines:
52 percent of coils go to the hot rolling mill finishing lines. This unit is responsible for reducing the weight of the coil, improving its mechanical properties, leveling the sheet, light and heavy cutting of the coil in 1 - 12 meter lengths.
