Abstract : In order to meet the high requirements of the customers on the thickness precision, shape and stam-ping performance of cold rolled sheets, process optimization of Hansteel cold rolling mill was carried out on the basis of the SPCC process system of the ordinary cold rolled plate. The optimization included that the thickness negative difference of cold rolled plate was set according to different thickness interval to ensure the overall thickness deviation of cold rolled plate with different thickness; degreasing and annealing processes were optimized to ensure the surface quality and mechanical properties of strip steel; the shape of the strip steel was further improved through the adjustment of work roll contour and elongation of SPM in the streching straighener of the re coiling line. The cold rolled plate for security door was successfully developed. This product was recognized by customers because of high thickness accuracy, good flatness and favorable me chanical properties.
Key Words: cold rolled steel for security door; thickness precision; shape; stamping performance; practice
引言
为树立产销研一体化的思想，深人市场，深入用
户，实现市场和现场的“无缝"对接，邯钢公司冷轧厂成立了产品开发组，实现产品的针对性定点开发。冷轧厂技术营销人员走访客户时，一些防盗门厂家反映市场上采购的冷轧板厚度精度低且负差不稳定、板形差、冲压性能不稳定。针对客户提出的一系列问题，冷轧厂调整冷轧板厚度负差，优化退火平整
