镀锡原板是梅钢1420冷轧投产后的重点产品,其对前工序热轧镀锡原板各项产品质量的要求均高于普通冷成型用钢。对梅钢1422热轧镀锡原板生产过程中存在的温度、表面、板形等质量问题进行了分析,并结合产线的自身特点和生产实际,从生产计划编排、板坯质量检验、热轧工艺改进等方面采取了有效措施,提高了热轧镀锡原板的产品质量,实现了稳定生产。 The original plate of tin plating is the key product of the Meishan Steel 1420 cold-rolled and put into production, and its requirements on the quality of various products of the hot-rolled tin plate in the previous process are higher than that of ordinary cold-formed steel. This paper analyzes the quality problems such as temperature, surface and plate shape existing in the production process of the 1422 hot-rolled tin plate of Meisteel. Combining with the characteristics of the production line and the actual production, from the planning of the production plan, the slab quality inspection, the hot rolling Process improvement and other aspects to take effective measures to improve the quality of the original hot-rolled tin plate, to achieve a stable production.
