Heat Treatment Line
Guocheng is the first manufacturer which can conduct heat treatment on hot-rolled coils after cross-cut-shearing in China. Currently, it is the wolrd’s main manufacturing base of high-end medium and thin gauge heat- treated sheet. Heat treatment processes such as quenching,normalizing, tempering,quenching+tempering and normalizing+tempering can be carried out. The annual production capacity is 1.2 million tons.
Guocheng is equipped with 13 heat treatment production lines(19 heat treatment furnaces and 7 quenching machines), 9 levelers, 3 packaging lines and 1 steel eco descaling line(SED). High-end heat-treated products including high-strength steel , wear-resistant steel , armor steel, ship plate and pressure vessel steel can be produced based on advanced rolling quenching technology and excellent leveling ability (the maximum tensile strength of product can reach 2200MPa).The product specification: thickness 2.0-25.4mm, width 900-2130mm,the 2mm quenched sheet is the thinnest high-strength heat-treated product in the world.
