摘要
以莱钢电炉连铸坯和圆钢为研究对象,探讨了常见轧制缺陷如折叠、辊印和褶皱以及划伤对圆钢热顶锻性能的影响,并对其引起的热顶锻开裂形态进行分析。轧制缺陷对圆钢热顶锻性能的影响严重,生产过程中应尽量避免。
Using Laigang＇s electric steel strand and the round steel as research objects, the infections of familiar rolling defects such as fold defects, roll marks, drapes and tears on round steel are discussed and the configuration of hot upset dehiscence aroused by it is analyzed. Then the rolling defects badly affect hot upset properties of round steel and should be avoided to the greatest extent.
