Ductile iron slag pot and cast iron slag pot

Ductile iron slag pot (slag landler) is mainly used to hold steel slag, waste and other items after steelmaking and ironmaking. 

Slag filling spheroidal graphite slag landler is one of the auxiliary equipment in 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 has been widely used in recent years. 

The slag pot (slag landler) products produced by Kunfeng heavy Industry are made of refractory material and cast iron. 

Kunfeng heavy Industry has been committed to the production of slag pot (slag landler) for 30 years. It has been studied that spheroidal graphite slag pot (slag landler) has the characteristics of impact resistance, cold and heat resistance and so on. 

The slag pot(slag landler) contains the cold liquid metal into the mold cavity and the gas and residue mixed in it, eliminates the cold insulation, pores and slag inclusion of the casting, increases the local temperature of the mold to achieve the heat balance of the mold, increases the strength of the thin-walled casting, prevents mold deformation, and is provided with an ejector rod under the slag collection pot (slag landler), so that there is no jacking rod trace on the casting surface; it can be used as a processing benchmark and a fixed part of clamping. 

When the spheroidal graphite slag landler is used, it is directly in contact with steel slag to withstand high temperature baking, steel slag temperature, and steel breakout to undertake molten steel under abnormal conditions. 

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, the heavy hammer is hit when the slag is cleared, and the destructive force. 

The residual stress of the casting is cracked by cold and heat. 

The source of residual stress: the wall thickness of slag filling landler 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. 

The process control of the production process is difficult, especially when the weight of the casting is more than 20T, the anti-decay, anti-segregation, anti-graphite floating and anti-stress crack are all strictly controlled. 

Nodular cast iron slag pot has been widely used in slag pot production and has become an ideal material because of its superior usability.
