The replacement method of converter
tapping hole includes the following steps:
Step 1: Putting the integral sleeve brick into the base
brick hole channel, adjusting the angle and position;
Step 2: Fixing the integral sleeve brick on the furnace body of the converter, filling the gap between the base brick and the integral sleeve brick with the
tapping hole grouting material, and sintering the
tapping hole grouting material with the waste heat in the converter. The beneficial effects are as follows: the replacement time is shortened by about 10 minutes each time compared with the existing methods; the service life of the tapping hole is increased by about 250 heats 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, realizing "shortening the replacement time of converter tapping hole, prolonging the service life of tapping hole, improving slag blocking rate, reducing production errors, and improving product quality and quality Low production cost ".
