Design of Cooling System Renovation for a Plate Continuous Casting Machine in a Steel Plant
Taking the production of a certain steel plant as an example,there are problems such as inclusions(slag),bubble defects,center cracks,and slab corner cracks in the slab.Based on the quality issues of the slab,the defects in the cooling system of the continuous casting machine will be identified,and a renovation plan for the cooling system will be proposed.The key points of the renovation strategy,such as optimizing the secondary cooling zone,optimizing the roll train,applying high-efficiency nozzles,and adding secondary filtration,will be analyzed.Experimental analysis was conducted on the modified cooling system,and the results showed that the quality of slab production was good,with significant cost reduction and efficiency improvement.
