摘　　要：通过对包钢生产的SWRCH35K产品冷镦开裂原因分析,确定以调整SWRCH35K钢的化学成分,优化炼钢、精炼、连铸、轧制生产工艺为攻关重点.改善了SWRCH35K冷镦钢的内部质量和表面质量,提高了冷镦性能.改进后的SWRCH35K盘条的冷镦开裂率为0.18%.By analyzing the cracking reason during SWRCH35K steel cold heading,the research programme was determined which includes grade＇s chemical composition adjustment,steel-making and refinement technology optimization.Meanwhile,continuous casting and rolling steel processes were also optimized.Internal and surface quality of the cold heading steel was improved,with the performance of the product being better than before.The rate of crack wire coil is only 0.18%.
