H型钢矫裂成因分析与改进

Cause Analysis and Improvement of H-Beam Cracking

针对马钢小H型钢生产线矫直美标w12系列产品出现的矫裂缺陷,通过对矫直辊压下量的优化、冷床的冷却水喷水时间减少、矫直辊圆角半径修改等措施,解决了美标w12系列产品的矫裂缺陷,提高了产品质量。

In view of the cracking defects on the American standard w12 series products which were strengthened by Maanshan Iron and Steel small H-beam production line,many measures such as optimizing the straightening roll reduction,reducing the cooling water spray time of the cooling bed and modifying the straightening roll fillet radius were taken,it solved the cracking defects of American standard w12 series products and improved product quality.
