整个轧钢生产过程总是有以下几个基本工序组成的：坯料准备，包括表面缺陷的清理，表面氧化铁皮的去除和坯料的预先热处理等。坯料的加热，是热轧生产工艺过程的重要工序。Thewholerollingprocessofsteelrollingisalwayscomposedofthefollowingbasicprocesses:Preparationofthebillet,includingthecleaningofsurfacedefects,theremovaloftheironoxideskinonthesurface,andthepreheattreatmentoftheblank.Theheatingofthebilletisanimportantprocessintheprocessofhotrolling.横轧有两种类型：一类是轧辊孔型沿轴向是不变的，沿径向呈周期变化。轧件主要靠径向变形实现成型。另一类是锲横轧工艺，即在两个或者三个互相平行布置的轧辊或两个平板的表面上.Therearetwotypesofcrossrolling:oneistherollpassisunchangedalongtheaxis,andtheotherisradialvariation.Theworkpieceismainlyformedbyradialdeformation.Theotheristhecrossrollingprocess,thatis,onthesurfaceoftwoorthreeparallelrollsortwoplates.轧钢机的技术现在越来越精细了，不同的类型，不同的物料都有不同的相对应的轧钢机设备，这也就让我们的物料更细致化了，且它们每一个地方的。Thetechnologyofrollingmillisnowmoreandmorefine,differenttypes,differentmaterialsh***edifferentcorrespondingrollingmillequipment,whichmakesourmaterialsmoredetailed,andtheyareperfecteveryplace.)
