Abstract：To address the operational condition where the ladle tilting direction at Meisteel's No.2 Steelmaking Plant is opposite to the slag dumping direction,the full ladle cover technology was introduced.Based on the process layout characteristics of the plant,a"quad-chain triple-claw"cover handling system was adopted.Through rational arrangement of ladles and cover handling devices,the system achieves cover removal upon arrival and cover installation upon departure,thereby resolving the technical challenge of opposing directions between slag turnover and hot repair operations.An automatic locking device was designed to enable slag dumping and hot repair tilting with the cover attached,resolving the challenge of overturning within limited pit spacing.The system achieves over 120° rotation during hot repair operations,while allowing partial opening of the covered ladle for refractory inspection and slag removal.After implementing the full ladle cover technology,the average temperature drop during tapping was reduced by 15℃,achieving the goal of production cost reduc-tion.
