摘　　要：基于炼钢—热轧—冷轧(热处理)工序全流程过程控制,利用现代数据通讯和数据库(数据云)技术创建了全过程质量管控数字化平台,并基于该平台开发了连铸板坯在线质量评级系统。该全过程质量管控数字化平台对炼钢过程中的原料、生产、工艺、设备等方面的参数进行实时监控和跟踪记录,并将跟踪结果以工艺事件的形式反馈到每一炉次和每块板坯上,通过制定相应的规则对连铸板坯进行分级评级,实现连铸板坯质量的在线实时预测评估,以确定连铸板坯分级修复处理方式。通过后工序轧制质量检验与判定,结果表明,该质量评级系统可以较为直观准确地分类筛选出具有不同质量风险等级的连铸板坯,降低了板坯缺陷发生比例,提高了连铸板坯质量。Based on the full process control of steelmaking-hot rolling-cold rolling(heat treatment)process,a digital platform for full process quality control was built using modern data communication and database(data cloud),and an online quality rating system for continuous casting slab was developed based on this platform.This digital platform for quality control throughout the entire process monitors and tracks the parameters of raw materials,production,processes,equipment,and other aspects in the steelmaking process in real time.The tracking results are fed back to each furnace and slab in the form of process events.By formulating corresponding rules,continuous casting slabs are graded and evaluated to achieve online real-time prediction and evaluation of continuous casting slab quality,in order to determine the grading and repair treatment method of continuous casting slabs.The quality inspection and judgment results of the subsequent rolling process show that the quality rating system can classify and screen continuous casting slabs with different quality risk levels more intuitively and accurately,reducing the proportion of slab defects and improving the quality of continuous casting slabs.
