热轧板/卷是以板坯(主要为连铸坯)为原料,经加热后由粗轧机组及精轧机组制成带钢。
热轧板卷从精轧最后一架轧机出来的热钢带通过层流冷却至设定温度,由卷取机卷成钢带卷,冷却后的钢带卷,根据用户的不同需求,经过不同的精整作业线(平整、矫直、横切或纵切、检验、称重、包装及标志等)加工而成为钢板、平整卷及纵切钢带产品。
简单点儿来说,一块钢坯在加热后(就是电视里那种烧的红红的发烫的钢块)精过几道轧制,再切边,矫正成为钢板,这种叫热轧。
由于热连轧钢板产品具有强度高,韧性好,易于加工成型及良好的可焊接性等优良性能,因而被广泛应用于船舶、汽车、桥梁、建筑、机械、压力容器等制造行业。
随着热轧尺寸精度、板形、表面质量等控制新技术的日益成熟以及新产品的不断问世,热连轧钢板、带产品得到了越来越广泛的应用并在市场上具有越来越强的竞争力。
