②Welding method
High-carbon ferrochrome manufacturers generally use electric welding, symmetrical welding and then integral welding when welding to avoid concentrated gravity points, which may cause cracking of the castings. When welding the first layer, if the seams are relatively If it is small, you can use 3.2 welding rods. For the second layer, you can use 4.0 welding rods. If the casting is larger, it can be welded in sections.
③ Crack repair
During the welding process, cracks will inevitably appear. After the cracks appear, grooves should be cut along both sides of the cracks. The depth and length of the grooves should be such that the crack part is cut off and then repaired again. When welding the cracks, the head should be sealed first. , there is a crack root and welding begins along the crack.

④ Temperature conditions
High-carbon ferrochrome manufacturers should cool down the first layer to 200-300°C at the layered welding site and clean the welding skin before welding the second layer, and so on.
