为了提高现有单机冷轧机的产量和扩大品种规格,采用在轧机前后增设卷取机数量而进行二层、三层和多层的轧制工艺具有现实意义。冷轧厂单机改造时无需更动主要设备只依轧制层数多少相应增加卷取机数量就行了。该工艺能减少改建投资,可提高产量和扩大品种规格,生产同样规格的产品与单层法相比可节省能耗,降低生产成本。“多层冷轧法”的特点“多层轧法”可充分利用轧机的可能弹跳值,在一定的弹跳值内利用多层轧制(一分为二,一分为三等),使每层板的厚度变小,根据板厚的需要 In order to improve the output of the existing stand-alone cold rolling mills and to expand the specifications of the mills, it is of practical significance to adopt two, three and more layers of rolling machines to increase the number of winders before and after the rolling mill. No need to change cold rolling plant single machine modification Major equipment only according to the number of rolling layer corresponding increase in the number of coilers on the line. The process can reduce the rebuilt investment, increase production and expand variety specifications. Compared with the single-layer method, products with the same specifications can save energy consumption and reduce production costs. “Multi-layer cold-rolling method” features “Multi-layer rolling method” can make full use of the possible bouncing value mill, within a certain bounce value using multi-layer rolling (one divided into two, one divided into three, Laminate thickness becomes smaller, according to the needs of the thickness
