宣钢4号高炉炉役后期合理炉型控制实践

摘要

针对炉役后期高炉特点,4#高炉始终把合理炉型控制放在科技攻关的首要位置,逐步形成了适应原燃料条件变化及炉役发展的高炉操作控制体系.结合宣钢4#高炉生产攻关操作实践,解析和探讨炉役后期高炉合理炉型稳定控制技术基本规律,进一步优化和改进炉役后期合理操作炉型管控技术.%According to the characteristics of the blast furnace at post campaign, No.4 BF always take the proper furnace profile control as the first place of technology research, and gradually formed the blast furnace operation control system which adapted to the original fuel condition changes and the furnace development.In combination with the production practices of No.4 blast furnace, it discussed the basic principle of proper furnace profile at post campaign, also optimized and improved the control technology of furnace operation.
