新一代炼钢厂功能优化与集成 张福明 崔幸超 张德国 （北京首钢国际工程技术有限公司，北京 100043 ） 1 摘 要 本文研究分析了现代化炼钢厂洁净钢生产技术，提出了以生产效率、制造成本和产品性能为核心的洁净钢 生产技术理念。通过对新一代炼钢厂高效率、低成本、高质量钢铁产品制造功能的解析与集成，结合首钢京唐钢铁 厂炼钢－连铸工艺的设计研究，应用动态精准设计体系，优化配置铁水预处理、转炉冶炼、二次精炼、连铸等单元 工序，构建了基于动态有序生产体系的高效率、低成本、高质量洁净钢生产平台。 关键词 炼钢 连铸 洁净钢 铁水预处理 二次精炼 Optimization and Integration of Function on New Generation Steelmaking Plant Zhang Fuming Cui Xingchao Zhang Deguo (Beijing Shougang International Engineering Technology Co., Ltd., Beijing, 100043) Abstract This paper analyzes the technology for clean steel production in modern steelmaking plant, a philosophy with production efficiency, manufacturing cost and product performance in its core. It also makes a review on functions of high-efficiency, low-cost and high-quality steel products manufactured by the new generation steelmaking plant, in combination with the study on design of steelmaking – continuous casting process of Shougang Jingtang Iron Steel Plant. By applying precise and dynamic design system to optimize and allocate systems and working procedures of hot metal pretreatment, converter smelting, secondary refining, continuous casting process, etc, a platform of high-efficiency, low-cost and high-quality clean steel production is built. Key words steelmaking, continuous casting, clean steel, hot metal pretreatment, secondary refining 1 引言 首钢京唐钢铁厂是我国“十一五”规划的重点工程，是按照循环经济理念，设计建设的新一代可循环钢 铁厂，具有优质产品制造、能源转换和消纳废弃物的三项功能。产品定位于高档次精品板材，设计产能 927.5 万 t 钢。建设 2 座 5500m3 高炉年产铁水 898.15 万吨，一个炼钢厂配置 2 座 300t 脱磷转炉、3 座 300t 脱碳转 炉和 3 台板坯连铸机，建设2250mm 和 1580mm 两条热连轧生产线，配置 2230mm、1700mm 和 1550mm 3 条冷轧生产线，冷热轧转换比为 57.2%，涂镀比为 65.7% 。 热轧主导产品为高品质汽车板，特色产品为管线钢、压力容器钢和造船用钢。高强度钢抗拉强度最高可 达 1200MPa，管线钢级别为X100 。冷轧产品包括固溶型、析出型、
