steel iron casting round ingot mould      

Three different kinds of material for ingot mold are spheroidal graphite cast iron , heat-resisting cast iron , gray pig iron .Relatively speaking , spheroidal graphite cast iron has good ductility and plasticity , higher strength than carbon steel , which can increase the times of use , lower the probabilities of cracking for ingot mold and can prolong the service time of ingot mold .

The ingot mold made by heat-resisting cast iron is widely used. Compared with nodular cast iron, heat-resisting furnace burden is added to heat-resisting cast iron, so which can lower cost and can be recast after being scraped. Due to the ductility of nodular cast iron, it has to be cutting after being scraped, which increases the labor cost. Due to the lower melting point of cast iron, normal gray pig iron can be used when using lower temperature pouring. The price of nodular cast iron is the highest of the three kinds of material, taking into account the price and the service time, nodular cast iron is the best choice.The material should be based on the working condition, type of cooling, way of removal slag and pouring method of different plants. Our company has much experience in ingot mold design and manufacturing. We can help customers choose material and develop drawings based on different working condition.
