钢的轧制，是整个轧钢生产过程的核心。坯料通过轧制完成变形过程。轧制工序对产品质量起着决定性作用。轧制产品的质量要求，包括产品的几何形状和尺寸内部***和性能以及产品光洁度三个方面。Therollingofsteelisthecoreofthewholerollingprocess.Theblanksarerolledtocompletethedeformationprocess.Therollingprocessplaysadecisiveroleinthequalityoftheproduct.Thequalityrequirementsofrollingproductsincludethreeaspects,includingtheinternalstructureandperformanceofthegeometricanddimensionalaccuracyoftheproductsandthefinishoftheproducts.轧钢生产对原料有一定的技术要求比如钢种，断面形状和尺寸，重量表面质量等。这些技术要求的考虑是保证钢材质量所必须的。也是确定和选择坯料时应具体要考虑的内容。Steelrollingproductionhassometechnicalrequirementsforrawmaterialssuchassteel,sectionshapeandsize,weightsurfacequalityandsoon.Thesetechnicalrequirementsarecideredtobenecessarytoensurethequalityofthesteel.Itisalsothecontentthatshouldbecideredwhendeterminingandselectingtheblank.单就冷轧机的轧制速度而言，其型号就可分为两种，一种是每秒线速度在3米的冷轧机，还有一种则是线速度在20米冷轧机，后面这一种设备已经可以算得上是快的了。Asfarastherollingspeedofthecoldrollingmillisconcerned,themodelcanbedividedintotwotypes,oneisacoldrollingmillwithalinespeedof3meterspersecond,andoneisthelinespeedinthe20metercoldrollingmill,andthelatteristhefastest.选择一批具有行业轧钢机设备技术制高点，能带动轧钢机设备行业和技术提高的建设项目作为行业技术示范项目，***力量研制核心技术和关键软件，实现轧钢机设备自动化和计算机控制系统的国产化。Abatchofctructionprojectswhichh***ethetechnicalheightoftheindustryrollingmillequipmentandthectructionprojectsthatcanimprovetheequipmentindustryandtechnologyoftherollingmillareselectedasthedemtrationprojectoftheindustrytechnology,andthecoretechnologyandkeysoftwarearedevelopedtorealizethelocalizationoftheautomationoftherollingmillequipmentandthecomputersystem.)
