Converter Lining Repair with Bricks

In the process of steelmaking in converter, due to the impact of molten iron and scrap on the lining, the scouring of the lining in the smelting of molten steel and slag, and the chemical erosion of the slag to the lining, the converter lining will be damaged to varying degrees during use. The lining is gradually thinned. When the lining is thinned to a certain thickness, the damaged part of the lining must be repaired in time.
In order to improve the converter operation rate, the principle of rapid sintering of magnesium carbide ladle bricks and residual slag of the converter at high temperature is utilized, and the existing furnace technology is boldly innovated and improved, and the bricks are used instead of materials to fix the converter. Fixing with firebricks saves more time and cost when compared to ramming mass.
Brick repair is a kind of furnace protection method with low cost and short sintering period. After the steel is finished, the steel can be repaired by pouring the residual bricks that meet the requirements of the furnace into the converter. By pouring it to the position need being repaired, using the residual heat in the slag after tapping, where the converter is damaged, the slag and the ladle are quickly sintered and formed to achieve the purpose of repairing the lining.
