基于工艺、设备、电气和液压多专业系统集成优化的理念,通过全面深入的理论研究和严谨细致的现场调试,成功地开发出了具有完全自主知识产权的先进的CISDI板坯连铸轻压下成套技术,其包含功能强大的算法先进的冶金工艺模型、结构优化的具有较高强度的扇形段设备、监控功能全面的基础自动化程序以及运行稳定可靠的液压系统平台和自动化系统平台,具备静态轻压下和动态轻压下两大控制功能,且具有位置控制、压力控制和软夹紧控制三种辊缝调节模式,并从设备保护和生产安全的角度考虑引入了扇形段时序压下、压下量自适应调整和漏钢预警强制保护等功能机制,该技术已在柳钢六号板坯连铸机上投入了正常的工业化应用,铸机生产顺利,系统运行稳定,在改善中心偏析和中心疏松等板坯内部质量方面取得了良好的冶金效果,从品种钢比例的提升以及铸坯探伤合格率的增加来看为柳钢创造了明显的经济效益。
Based on the concept of integration and optimization of multi-specialty systems of process, equipment, electrical and hydraulic systems, the company has successfully developed the advanced CISDI slab continuous casting with complete independent intellectual property rights through light and pressure reduction through comprehensive and in-depth theoretical research and rigorous meticulous on-site commissioning Complete technology package with powerful algorithms Advanced metallurgical process models, structurally optimized segment units with higher strength, comprehensive automation of basic monitoring functions and a stable and reliable hydraulic system platform and automation system platform with static light Pressure and dynamic soft reduction under the two control functions, and has position control, pressure control and soft clamping control of three kinds of roll gap adjustment mode, and equipment protection and production safety point of view the introduction of the fan section timing pressure, pressure Adaptive adjustment of lower volume and pre-warning of breakout. The technology has been put into normal industrial application on Liuzhou Slab Caster Caster, the smooth casting machine runs smoothly and the system runs steadily. While improving the center segregation and center Loose and other internal quality slab has made a good metallurgical effect, from the proportion of varieties of steel to enhance and cast Billet flaw detection rate of increase of view for the Liuzhou Steel has created significant economic benefits.
