摘要
介绍了天钢利用转炉—精炼—VD—方坯连铸—轧钢工艺生产抗硫酸露点腐蚀09CrCuSb圆钢的开发过程。通过精炼的强化脱氧、化学成分的精确控制、连铸二冷工艺的优化和轧钢工艺的精确温度控制,开发出了09CrCuSb圆钢并形成完整的生产工艺。经检测该产品完全符合相关标准,达到了设计要求。所生产的圆钢得到用户的好评。
The paper describes the developing process of 09CrCuSb sulfuric acid dew point corrosion resistant round steel in the production route of converter - refining - VD - CCM - rolling by Tianjin Iron and Steel Group Company Limited （TISCO）. Through adopting strengthened deoxidization in refining, strictly controlling chemical composition, optimizing secondary cooling process at casting and precisely controlling temperatures at rolling, 09CrCuSb round steel was developed and its complete production process came into being. Since fully meeting relevant standards in inspection and reaching design requirement, the produced round steel received good comments from the customer.
