1.First, thoroughly remove the steel slag, residual steel, steel and impurities infiltrated into the cracks on the repair surface. If the refractory material is pulverized by water, it should be completely removed until the refractory brick is exposed.
2.After the slag line is replaced, place the bottom of the EAF, hoist the ramming material into the EAF, and distribute the knotted material on the repaired surface as required to form a material layer with a height of about 150mm until it is covered with the repaired surface.
3.Distribute the material evenly, and use a special air vibration fork to poke each part of the material layer from the center of the molten pool to the EAF slope.
4.Repeat the operation twice until the EAF bottom ramming material is dense. Repeat the above steps until a suitable molten pool shape is formed.
