热轧。济钢一级代理用连铸板坯或初轧板坯作原料，经步进式加热炉加热，高压水除鳞后进入粗轧机，粗轧料经切头、尾、再进入精轧机，实施计算机 控制轧制，终轧后即经过层流冷却和卷取机卷取、成为直发卷。直发卷的头、尾往往呈舌状及鱼尾状，厚度、 宽度精度较差，边部常存在浪形、折边、塔形等缺陷。

Hot-rolling。 Jinan an agent for continuous casting slab or as raw material, after reheating furnace heating, descaling into the roughing mill of high pressure water, roughing material by cutting head, tail, and then enter the finishing mill, the implementation of the computer controlled rolling and after rolling through the laminar cooling and coiling reel, become straight volume. Hair straightenerrollhead, tail tongue shapeand thefishtail shape, thickness, width of poor accuracy, edgehaswavy, folding, tower and other defects.

济钢一级代理其卷重较重、钢卷内径为760mm。将直发卷经切头、 切尾、切边及多道次的矫直、平整等精整线处理后，再切板或重卷，即成为：热轧钢板、平整热轧钢卷、纵切带等产品。热轧精整卷若经酸洗去除氧化皮并涂油后即成热轧酸洗板卷。

The first grade agent of Jigang is heavy in weight, and the inner diameter of steel coil is 760mm. Thestraightthroughcutting head cutting, cutting tail, cutting edge and multi pass straightening and leveling finishing line processing, cutting board or heavy volume, which becomes: hot rolled steel plate and flat steel coils, slittingstripand other products. Hot finishing rolling by pickling descaling and oil is made by pickling hot-rolled coils.

冷轧。济钢一级代理用热轧钢卷为原料，经酸洗去除氧化皮后进行冷连轧，其成品为轧硬卷，由于连续冷变形引起的冷作硬化使轧硬卷的强度、硬度上升、韧塑指标下降，冲压性能恶化，只能用于简单变形的零件。轧硬卷可作为热镀锌厂的原料，因为热镀锌机组均设置有退火线。轧硬卷重一般在6~13.5吨，钢卷内径为610mm。

Cold rolling. An agent of Jigang hot rolled steel coil as raw material by pickling descaling after cold rolling, the finished rolling hard volumes, due to continuous deformation caused by cold hardening the hard roll strength and hardness of the rise and decline of toughness index, stamping performance deterioration, only for a simple deformation of parts. Rolled hard coil can be used as raw material for hot galvanizing plant, because the hot galvanizing line is equipped with annealing line. The rolling hard weight is usually 6~13.5 tons, and the inner diameter of the coil is 610mm.
