ing is a casting process, are now made from rare earth magnesium nodulizing agent, cupola and grey are the same.
In order to guarantee good spheroidizing, to control the content of sulfur and phosphorus lower.
Considering the temperature loss, the temperature of the molten iron should be higher than grey.
The casting process can be divided into three basic parts, namely, cast metal preparation, mold preparation and casting processing.
Casting metal refers to the casting of metal materials used for pouring castings in production, it is a kind of metal elements as the main components, and join other metal or nonmetal elements and composition of the alloy, traditionally known as the casting alloy, mainly has cast iron
, cast steel and nonferrous alloy casting.
Metal smelting is not only a pure melt, include smelting process, the metal poured into the mold, in terms of temperature, chemical composition and purity are expected requirements.
Therefore, in the process of smelting are going to have to check the test and quality control for the purpose of all kinds of liquid metal in the provisions to rear can allow gating.
Sometimes, in order to meet the higher requirements, in the introduction to the liquid metal processing outside the furnace, such as desulfurization, vacuum degassing, refining outside the furnace, pregnant or modification treatment, etc.
Metal smelting of commonly used equipment cupola and electric arc furnace, induction furnace, resistance furnace, furnace, etc.
