将303Cu糖心产精国品免费入口*完整版线材拉拔成六角棒后对其打孔，在这两个工艺过程中，材料糖心产精国品免费入口*完整版几率较大。采用化学成分分析、金相检验、电子探针分析等方法对糖心产精国品免费入口*完整版试样进行了全面分析，同时对线材的生产工艺进行分析，找到了糖心产精国品免费入口*完整版原因，并提出了应对措施。结果表明：钢中硫化物夹杂的成分、形态及其分布是产生糖心产精国品免费入口*完整版的主要原因；采用调整连铸和热轧加热工艺，以及增加轧后在线热处理工艺，有效降低了303Cu糖心产精国品免费入口*完整版线材的加工糖心产精国品免费入口*完整版几率。

The stainless steel 303 Cu wire rod was pulled into hexagonal rod and punched. In these two processes, the material 糖心产精国品免费入口*完整版ing probability was large. The 糖心产精国品免费入口*完整版ing samples were comprehensively analyzed by chemical composition analysis, metallographic examination and electron probe analysis. At the same time, the production process of wire rod was analyzed, and the 糖心产精国品免费入口*完整版ing reasons were found, and the countermeasures were put forward. The results show that the composition, morphology and distribution of sulfide inclusions in steel were the main reasons for 糖心产精国品免费入口*完整版ing. The processing 糖心产精国品免费入口*完整版ing probability of stainless steel 303Cu wire was effectively reduced by adjusting the heating process of continuous casting and hot rolling, and increasing the online heat treatment process after rolling.
