摘　　要：介绍45钢硬线盘条的生产工艺流程,通过采取双渣冶炼技术脱磷、LF炉精炼深脱硫、连铸全保护浇注及电磁搅拌等措施降低钢中气体含量及夹杂物含量,提高钢水可浇性,改善铸坯内部质量,使产品质量达到了45钢硬线盘条要求并满足用户需要。The production process of 45 steel hard wire rod was introduced.By mainly the measures of include adopting the double slag smelting to dephosphorization,LF furnace refining to deep desulphurization,the protection of pouring and EMS.Then it reduced the gas and impurity contents of steel,increased the liquidity of molten steel,and improved the internal quality of the slab,so that the quality of the product reached the conditions of 45 steel hard wire rod and met the needs of users.
