一、改进前的车间生产状况由于生产车间没有保温炉担负铁水的保温、升温和浇注工作,因此3吨工频感应电炉既要熔化铸铁,又要进行保温、升温及浇注等工作。但是鉴于造型线的特点,由于浇注周期短,从而使3吨工频炉在造型线生产期间几乎完全处于出铁状态,没有空余时间去熔化铸铁,所以只能在一炉铁水出完后,才能加料熔化。此时,熔化工部已无铁水供应,造型线只好停止生产。二、3吨无芯工频感应电炉供电方式的改进
First, to improve the status of the workshop before the workshop because there is no holding furnace holding hot metal hot metal insulation, heating and pouring work, so 3 tons of frequency induction furnace not only to melt the cast iron, but also for insulation, heating and pouring work. However, due to the characteristics of the molding line, due to the short pouring period, the 3-ton industrial frequency furnace is almost entirely in the tapping state during the molding line production and has no free time to melt the cast iron. Therefore, only after a hot metal is discharged Feed melting. At this point, the melting department has no hot metal supply, modeling line had to stop production. Second, 3 tons of coreless frequency induction furnace power supply improvements
