在批林整风运动推动下,我车间于1973年11月初自行设计、制造了一台2吨有芯工频感应电炉,与冲天炉直接双联,配合半自动射压造型生产线使用。今年初,根据上级公司新的生产任务,又建成了第二台2吨有芯工频感应电炉。两台电炉均可采用冷熔炼,也可与冲天炉间接双联生产。通过初步熔炼实践表明,它对于铁水的保温、升温效果较好,用于生产合金铸铁比较理想。一、炉子的选型根据上级公司给我厂生产合金铸铁和高强度铸铁的任务,我们决定采用电炉作熔炼设备。众所周知,可用于熔炼合金铸铁的电炉有
Under the campaign of rectification of forest rectification, our workshop was designed and manufactured by ourselves in early November, 1973 with a 2-ton core frequency induction induction furnace. It is directly connected with cupola and used with semi-automatic injection molding production line. Earlier this year, according to the company’s new production tasks higher level, but also built a second 2-ton core frequency induction furnace. Two electric furnace can be cold smelting, but also indirect cupola production. Through preliminary melting practice shows that it is better for hot metal insulation, heating effect is better for the production of alloy cast iron ideal. First, the selection of the furnace According to the superior company to our factory production of alloy cast iron and high-strength cast iron task, we decided to use electric furnace for melting equipment. It is well-known that there are electric furnaces that can be used to smelt alloy cast iron
