The hot-rolled steel plate production line uses steel billets as raw materials and operates entirely at high temperatures: Steel billets are heated in a furnace to 1100-1250℃, giving them good plasticity. They then enter the roughing mill, where they are widened and significantly thinned through reversible rolling, achieving preliminary forming. Next, they enter the finishing mill group, where the thickness is precisely controlled through multi-pass continuous rolling (as thin as 1.2mm and as thick as over 200mm). Immediately after rolling, they are rapidly cooled via a laminar cooling system (with the cooling rate controlled according to the steel grade). Finally, the plate surface is flattened by a leveler, followed by fixed-length shearing (or coiling into rolls). After inspections for dimensional accuracy and mechanical properties, they become finished hot-rolled steel plates.

The production line is compatible with various thickness specifications, and its products are widely used in fields such as construction and machinery.
