Ingot mold / resistant cast iron ingot mold / cast film / River River steel ingot mold casting production from ductile material divided ingot mold, heat-resistant cast iron, gray cast iron three, relatively speaking, because of their plasticity and ductile ingot mold toughness, high strength than steel but also can increase the frequency of use of the ingot mold, reducing breakage opportunity to increase the use of ingot mold life, ingot mold ingot mold products, plum ingot mold, square ingot mold, round ingot mold, integrally molded, dual-electrode blank open ingot mold, ferrochrome ingot mold, 100 tons more than ingot molds, cast iron ingot mold resistant, ductile iron ingot molds, cast film, anode mold, mold, laboratory ingot mold, alloy ingot mold, heat pressure die cast iron ingot mold. Use heat-resistant cast iron ingot mold of the most widely used, due to the heat-resistant cast iron itself added charge, compared with ductile castings, both cost but again broke down at the end after a reported fee, melted recast. Ductile iron ingot mold fee reported after use, due to the toughness of ductile itself, the use of cutting fracture, thus increasing labor costs. Ordinary gray cast iron ingot mold and comparison of two or more materials, pouring temperature should end in ductile cast iron ingot mold ingot mold and heat, it is more the end of the melting point of iron, so that the bottom temperature can be used to burn NOTE ordinary gray cast iron. Cast molded directly repeated contact with the hot iron, both to withstand oxidation loss and financial loss, but also bear the cold tired, very poor working conditions. In the casting process, the cast iron to the mold caused by the high temperature molten iron rapid heating, rapid cooling and water cooling caused by frequent changes in the temperature of 250 ~ 1250 ℃, while in the thermal cycling process, each pig mold at the same instant the temperature distribution is not uniform throughout, large temperature gradient.
