上海安亭铸铁厂是生产汽车拖拉机铸件的铸造专业厂,目前还在基建、安装、调试阶段,尚未正式投产。该厂造型是采用三工位高速高压全自动造型流水线。熔化工部采用了冲天炉熔化、有芯工频感应电炉升温保温及调节铁水成分的双重熔炼工艺。冲天炉熔化铁水生产率较感应炉高,成本一般也比感应炉低,但是,铁水在冲天炉中过热成本却较高,而在感应电炉中过热铁水,电耗则较小,同时利用感应电炉的电磁搅拌作用,对调节铁水成分又很有利。因此,两者双联使用,可以相互取长补短。对于同样容量的感应电炉而言,有芯感应炉比无芯感应炉具有投资低、电效率较高、操 Anting Iron Casting Factory in Shanghai is the production of automotive tractor castings professional casting factory, is still in infrastructure, installation, commissioning phase, not yet officially put into operation. The factory modeling is the use of three high-speed high-pressure automatic molding line. Melting Department adopted a cupola melt, core frequency induction furnace heating and temperature control and adjustment of the composition of the double melting process. Cupola melting hot metal production rate higher than the induction furnace, the cost is generally lower than the induction furnace, however, hot metal in the cupola overheating costs are higher, while in the induction furnace overheated hot metal, power consumption is smaller, while the use of induction furnace Electromagnetic stirring effect, the composition of the hot metal is very beneficial. Therefore, the two can be used in tandem to complement each other. For the same capacity of induction furnace, core induction furnace coreless induction furnace with low investment, higher electrical efficiency, operation
