摘要
介绍了唐钢550 MPa级别的热成型钢的方法及过程,确定炼钢成分范围,由酸连轧机组生产冷硬钢带,冷硬钢带再通过退火涂镀工艺形成最终产品.通过对热轧板坯的出炉温度、酸洗质量、冷硬压下控制,以及涂镀的清洗、退火、光整等关键工艺参数控制,成功生产550 MPa级别的热成型钢.该产品具有较好强度和韧性,为热冲压件提供低强度区,保证了汽车的安全性能.
Abstract
This article introduces the method and process of hot formed steel of Tang Steel's 550 MPa grade,determines the range of steelmaking composition,and produces cold hard steel strips through acid rolling mill.The cold hard steel strips are then annealed and coated to form the final product.By controlling the hot rolled slab and furnace temperature,pickling quality,cold and hard pressing,as well as key process parameters such as cleaning,annealing,and finishing during coating,550 MPa grade hot formed steel has been successfully produced.This product has good strength and toughness,providing a low strength zone for hot stamping parts and ensuring good automotive safety performance.
