热轧低碳钢折皱缺陷形成原因分析与改善

Formation Mechanism and Improvement of Wrinkle Defects for Hot-rolled Low Carbon Steel Coil

针对热连轧低碳钢钢卷在开平过程中出现的折皱缺陷,从碳含量、压下率和不良板形三个方面分析了低碳钢产生折皱的原因,并根据结果进行了改进。

Base on the low- carbon steel＇s wrinkle defects happened during the sizing operation, this issue analyzes the formation mechanism from three aspects： carbon content, screw - down rate, bad shape, and give the improvement.
