Ａ宝钢冷轧板实现负公差轧制全自动化宝钢冷轧板材近日实施国际上先进的轧制工艺——负公差轧制和理论计重。宝钢从１９９４年起对冷轧板材实施负公差轧制作了一系列的研究，并对有些设备进行了改造，目前全自动生产控制系统运作良好，成品板材厚度控制在规定的负偏差范围... A Baosteel cold rolled sheet to achieve full tolerance of negative tolerance Baosteel cold rolled sheet recently implemented international advanced rolling process - negative tolerance rolling and theoretical weight. Baosteel has conducted a series of studies on the implementation of negative tolerance rolling of cold-rolled sheet since 1994, and has reformed some of the equipment. At present, the fully automatic production control system works well and the finished sheet thickness is controlled within the specified negative deviation range.
