工频无心感应熔炼炉,在我国大量应用已有20余年的历史,积累了工业运行经验,取得了可喜的成果。例如第二汽车厂,几乎所有的黑色及有色金属熔炼,全部采用工频无心炉进行;新建的二汽第三铸造厂规模更大,将采用5台20t无心熔铁炉。不少铸造行业也准备在“七五”规划中,加以改造或扩建,拟采用这一先进的工艺装备。无心炉具有诸多优点:它对于大批量和小批量、连续和间断式的单、多品种生产部能适应。制品质
Frequencies of heartless induction melting furnace, a large number of applications in our country has more than 20 years of history, has accumulated experience in industrial operation, and achieved gratifying results. For example, the second automobile plant, almost all of the black and non-ferrous metal smelting, all using frequency-free heart furnace; new second-steam third foundry larger, will use 5 20t heartless melting furnace. A lot of foundry industry is also ready to be transformed or expanded in the “Seventh Five-Year Plan”, and it is planned to adopt this advanced technology and equipment. The heartless furnace has many advantages: it can be adapted to large and small batch, continuous and intermittent single and multi-variety production sections. Quality system
