Optimization improvement and practice of ladle age and safety protection
By analyzing the factors that affect the age and safety performance of the ladle,measures such as optimi-zing the refractory material of the ladle brick,protecting key parts of the ladle masonry,accurately measuring the residual thickness of the refractory material online,optimizing the top slag composition structure of the ladle refi-ning,and applying ladle safety protection technology are taken to improve the age and safety protection performance of the ladle.The average total ladle age reached 185 times,with the highest ladle age reaching 202 times,an in-crease of 73 times from the previous average of 112 times.The investment costs of refractory materials and ladles have significantly decreased.The accident rate of ladle usage has decreased from 0.6 times per 10000 tons of steel to below 0.05 times per 10000 tons of steel,providing a favorable guarantee for the improvement of ladle age.
