针对唐钢某热轧生产线生产的含硼钢A36出现了边部重皮缺陷（部分较严重的存在裂纹）问题，系统地分析了缺陷产生的原因。指出通过采取控制钢中[N]、[B]、[Al]的含量，适当添加[Ti]，减少板坯连铸二冷水量及优化热轧工艺等措施，可显著地减少边部重皮缺陷的发生。

침대당강모열알생산선생산적함붕강A36출현료변부중피결함（부분교엄중적존재렬문）문제，계통지분석료결함산생적원인。지출통과채취공제강중[N]、[B]、[Al]적함량，괄당첨가[Ti]，감소판배련주이랭수량급우화열알공예등조시，가현저지감소변부중피결함적발생。
Aiming at the edge surface peeling defect ( serious existence crack defect ) that occurred in boron steel A36 produced by a hot rolling production line in Tangshan Steel , this paper systematically an-alyzed its causes, and pointed out that by controlling the content of [N] in steel, [B], [Al], adding [ Ti] , reducing the second cooling water volume of slab casting and optimizing hot -rolling process , the occurrence of edge surface peeling defect can be greatly reduced .
