重卷机组汽车板设备升级改造探讨
Discussion on Equipment Upgrading and Reconstruction of utomobile Sheet of the Recoil Line

对首钢冷轧某重卷机组设备进行深入的研究讨论，以完成机组汽车板生产能力的升级改造。通过对开卷机、纠偏辊、张力辊、涂油机、定位卷取等关键设备的技术分析，确保升级后的机组满足高级汽车板的生产。经过升级改造，该重卷可以满足高级别汽车板的切边需求、3802等高粘度油品的涂油需求、卷取后钢卷的小溢出边的需求、带头硌印控制在20米以内的需求，完全达到生产高级汽车板的要求，为相似机组的升级改造提供参考。
By researching the equipment of the recoil line of Shougang Cold Rolling Co., Ltd., upgrade of the production capacity of the automobile sheet was completed. Through the technical analysis of the payoff reel, steering roll, bridle roll, oiler, and coiler, made sure that the new line met requirement of the advanced automobile sheet. After upgrading, the need for the advanced automobile sheets’ edge trimming, the oiling need of high-viscosity oils such as 3802, the need for small overflow edges of the coil after winding and the need for the head print defect control within 20 meters were met, which can fully meet the requirements of producing advanced automotive sheets. The paper provided reference for the reformation and upgrading of the similar production line.
