The slag pots, also known as the slag tank, is to contain the cold liquid metal into the mold cavity and the gas, residue, cold isolation, stomata and slag inclusion of the castings, so as to increase the local temperature of the mold so as to achieve the heat balance of the mold and increase the strength of the thin-walled castings. to prevent deformation during demoulding, an ejector rod is arranged under the slag collecting basin, so that there is no jacking rod trace on the casting surface, which can be used as a processing benchmark and a fixing part.
Slag pots slag tank is one of the auxiliary equipment in the metallurgical industry, which is used to hold steel slag and waste during steelmaking and ironmaking. The traditional material is gray cast iron, and nodular cast iron is widely used in recent years. When the slag pots is in use, it is directly in contact with steel slag to withstand high temperature baking, and the steel slag temperature is high. Under abnormal circumstances, steel breakout takes on molten steel.
Under normal circumstances, the load of slag basin is self-weight and slag weight, and the load increases sharply during breakout. Once the steel is glued to the slag pots, 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. The source of residual stress is that the wall thickness of slag basin is uneven and different, and thermal stress is formed in the cooling process. The slag basin with high residual stress will crack quickly after being chilled and heated. It is difficult to control the production process of nodular cast iron slag pots slag tank, especially when the casting weight is over 20T, the anti-decay, anti-segregation, anti-graphite floating and anti-stress crack need to be strictly controlled.
