Development and application of online slab quality rating system
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 plat-form for quality control throughout the entire process monitors and tracks the parameters of raw materials,produc-tion,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 quali-ty,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.
