随着国民经济的发展,铝材的用量日益增加。目前我国熔炼铝及其合金,大都采用燃料炉,其缺点是效率低,耗能大,质量不稳定,污染严重,使用工频炉能够克服上述缺点,又具有高效、节能、无污染等优点。近年来,虽发展一些小容量的铁坩埚工频熔铝炉,但满足不了生产工艺要求。随着电力工业的发展和环境保护要求日趋严格,发展高水平工频熔铝炉取代燃料炉,势在必行。GWL系列工频感应熔铝炉是福建电炉厂吸收国外先进技术和同类型感应炉的优点,进
With the development of the national economy, the amount of aluminum is increasing. At present, China smelting aluminum and its alloys, mostly using fuel furnace, the disadvantage is inefficient, energy consumption, quality instability, serious pollution, the use of frequency furnace can overcome the above shortcomings, but also has the advantages of high efficiency, energy saving, pollution-free. In recent years, although the development of some small-capacity iron crucible frequency melting furnace, but can not meet the production process requirements. With the development of the power industry and the increasingly stringent environmental protection requirements, it is imperative to develop a high-level industrial frequency melting furnace to replace the fuel furnace. GWL series frequency induction melting furnace is Fujian Electric Furnace plant to absorb advanced foreign technology and the advantages of the same type of induction furnace, into
