Slag pot, slag landler material selection

Slag basin, slag pan and slag irrigation are traditionally made of gray cast iron, but ductile iron has been widely used in recent years. When slag irrigation is used, it is directly in contact with steel slag to withstand high temperature baking, and the steel slag temperature is high. Under abnormal conditions, steel breakout takes on molten steel. Under normal circumstances, the slag filling load is self-weight and slag weight, and the load increases sharply during breakout. Once the steel is glued to the can, it will be hit by a heavy hammer when cleaning the slag, which is destructive. The residual stress of the casting is cracked by cold and heat. Residual stress source: slag irrigation wall thickness is uneven, the difference is large, and thermal stress is formed in the cooling process. The slag with high residual stress will crack quickly after cold and heat. It is difficult to control the production process of ductile cast iron slag ladle, especially when the casting weight is more than 20T, the anti-decay, anti-segregation, anti-graphite floating and anti-stress crack need to be strictly controlled. Slag pan slag pot is one of the auxiliary equipment in metallurgical industry, which is used to hold steel slag and waste during steelmaking and ironmaking. The slag plate is used to contain the cold liquid metal into the mold cavity and the gas and residue mixed in it, to eliminate the cold insulation, stomata and slag inclusion of the casting, to increase the local temperature of the mold to achieve the heat balance of the mold, and to increase the strength of the thin-walled casting. prevent deformation during demoulding; slag plate is also a kind of slag irrigation. The ejector rod is arranged under the slag pan (slag irrigation), so that there is no ejector rod trace on the casting surface, which can be used as the processing benchmark and the fixing part of the clamping.
