铸造、锻压、焊接作为三大基础热加工工艺,为现代装备制造业提供大部分零件毛坯。随着大批量生产的汽车、工程机械、轨道交通等行业快速发展,铸造产业、锻压产业迎来难得的发展机遇。经过近30年的快速发展,铸造造型工艺、砂处理工艺、清理工艺及熔炼(保温)设备等,向自动化、高效节能、环保发展,产品升级转型已迫在眉睫。目前,国内中频熔炼炉熔化每吨铁液耗电量是550～650kW·h,国外先进熔炼设备熔化每吨铁液 Casting, forging, welding as the three basic thermal processing technology, for the modern equipment manufacturing industry to provide most of the parts rough. With the mass production of automobiles, construction machinery, rail transportation and other industries rapid development, foundry industry, forging industry usher in a rare opportunity for development. After nearly 30 years of rapid development, casting molding process, sand treatment process, cleaning process and melting (insulation) equipment, to the automation, energy efficient, environmentally friendly development, product upgrading transformation is imminent. At present, the domestic intermediate frequency melting furnace molten iron consumption per ton of liquid iron is 550 ~ 650kW · h, foreign advanced melting equipment melts per ton of liquid iron
