Boundary determination of leveling capacity for plate roller leveler based on curvature integration methodLIU Zhi-fang(刘志芳)1, LUO Yuan-xin(罗远新)2, YAN Xing-chun(严兴春)2, WANG Yong-qin(王勇勤)2(1. College.... The typical ranges of the leveling capacity are expressed by several boundary curves which are helpful to judge whether the incoming plate can be leveled quickly or not. Also, these curves can be used......

轧制加工低合金板钢表面边部裂纹机制研究徐震1,华蔚1,江来珠1(1.上海市宝钢股份有限公司)摘 要:通过"模铸+初轧"工艺轧制低合金钢锭时,钢板易在表面距边部100 mm左右易出现直线型裂纹,裂纹或深或浅,有规律,导致报废量大大增加,影响了正常生产.该类缺陷曾被认为是轧制缺陷,从宏观形貌及微观组织等多方面研究缺陷形成机制,判定源于钢锭表面内在和外在微裂纹缺陷,初轧轧制时轧件在受到拉应力最大的地方产生开裂,从而为产品质量改进提供了理论依据,通过采取有效的技术措施,大大减少了该类缺陷发生的几率. 关键......
