The method includes the following steps: Step 1. Put the entire set of bricks into the hole of the seat block, and adjust the angle and position; Step 2. Fix the overall set of bricks on the furnace body of the converter, and fill it with grout from the taphole. The gap between the seat brick and the overall set of bricks can be sintered by using the waste heat in the converter to grout the taphole.
The beneficial effects are: the replacement time is shortened by about 10 minutes each time compared with the existing method; the life of the tap hole is increased by about 250 furnaces compared with the existing method; the success rate of slag blocking is increased by 10% compared with the existing method; the cost per ton of steel is reduced by about 0.15 yuan, the purpose of shortening the replacement time of the converter tap hole, extending the service life of the tap hole, increasing the slag blocking rate, reducing production errors, improving product quality and reducing production costs was achieved.
