introduction：The process is outlined below： Water cooled metal type centrifugal casting process diagram Smelting Place ingredients(Steel scrap、Pig iron、Return charge, etc)Adding furnace(Induction furnace or cupola)，And the composition is adjusted，When the ingredients meet the process requirements，The hot metal is poured into the variable-frequency holding furnace for spheroidization。For example, the sulfur content in hot metal exceeds the standard，It needs to be desulfurized first。 nodulization When the composition and temperature of molten iron meet the process requirements，The spheroidizing agent is added to the hot metal，The flake graphite in hot metal is changed into spherical graphite，Send to centrifugal pouring department for pouring。

introduction：1introduction At present, the installed capacity of Chinas electric power industry reaches3.16Hundred millionkW，The annual electricity generation is up13500Hundred million kWh。Chinas electricity consumption ranks second in the world after the United States，But our country per capita electricity only1038kWh，Less than the level of electricity consumption in developed countries10。 Last summer，Our country continues to be extremely hot，As a result, some cities have cut off electricity due to tight power supplies。The electricity shortage has changed from seasonal to year-round，Emergence of power、Power double gap，Unit long-term high load operation，Failure increase。Our country is in the rapid transition to large-scale industrialization and urbanization
