Abstract
A method for converter lining repairing includes the residue in the converter of the final slag from the earlier melting, the application of slag skull on the lining by rotary gun mix tuyere with nozzles by blowing the slag bath from above with the neutral gas jets and supplying gun mix on the side surface of the converter in oxidative jets with the variable-height of the gun mix tuyere and change the direction of jets rotation in opposite after each turn of tuyere by 180° around the vertical axis. Blowing of the slag bath is carried out with simultaneous supplying of neutral gas jets and the central oxygen jet, which supplies powdered dolomite in the slag bath, with the supplying the air jets, which supply powdered magnesite to the lateral surface of the lining.
