摘　　要：安钢第一炼轧厂采用100t LD-LF-150方坯连铸机(6机6流)-无扭控冷轧制工艺路线生产胶管钢丝用C72DA热轧盘条。其关键工艺控制:转炉冶炼终点碳(C)0.50%～O.60%,精炼炉控制精炼时间大于55min,保证上钢前弱吹氩8～15 min,最大限度去除钢水中夹杂物;连铸中间包温度控制在1 490～1 502℃之间,拉速2.1m/min,采用结晶器电磁搅拌,全程保护浇注。试验结果表明,盘条实物质量和力学性能完全满足技术标准和用户使用要求。Wire Rod C72DA for High pressure Hose of was made by LD - LF - CCM process in No 1 steel - making plant of Anyang Steel. Key process parameters are as follows; carbon content is 0.50% to 0.60% at converter taping, refining time is more than 55 minutes in refining furnace, weak argon blowing is kept for 8 - 15 minutes before pouring to remove inclusions in steel as much as possible, cast tundish temperature is controlled between 1 490℃ and 1 502℃ , casting speed is 2.1 m/min, electromagnetic stirring is used in mold and protective casting is carried out from beginning to end. The test has shown that product quality and its physical properties fully satisfy requirement.
