摘　　要：通过断口形貌、金相组织和扫描电镜断口分析,结合热轧酸洗板SPHC的生产数据,认为钢中的硫含量过高,导致硫化物非金属夹杂物大量存在于钢中,尤其钢板厚度心部最为严重,降低了钢的塑性,在旋压的过程中部分料片无法承受厚度中心位置的旋压而开裂。针对旋压用途的热轧酸洗板SPHC,需进行特殊特性的识别,进行严格的硫含量控制。Through the analysis of fracture morphology,metallographic structure and SEM fracture,combined with the production data of hot-rolled pickling plate SPHC,it is considered that the high sulfur content in the steel results in a large number of sulfide non-metallic inclusions in the steel,especially in the center of the steel plate thickness,which reduces the plasticity of the steel.During the spinning process,some pieces cannot bear the spinning at the center of the thickness and crack.For the hot-rolled pickling plate SPHC used for spinning,it is necessary to identify the special characteristics and control the sulfur content strictly.
