针对有芯感应熔铝炉石英砂熔沟使用寿命短,严重影响生产问题,丹东耐火材料制品厂、渭阳柴油机厂、本溪合金厂和西安电炉研究所,协同组织了“三结合”研制小组,进行了反复试验研究工作,最近取得较显著的成效。 过去有芯感应熔炼炉,在熔炼铝、镁等有色金属时,熔沟多用石英砂等材料捣打而成, Aiming at the short service life of fused sand with fused quartz sand core in quartz core induction furnace, the production problems are seriously affected. Dandong Refractories Products Factory, Weigang Diesel Engine Factory, Benxi Alloy Plant and Xi’an Electric Furnace Research Institute co-organized a “triple combination” Conducted repeated trial research work, recently achieved more significant results. In the past, there was a core induction melting furnace, melting aluminum, magnesium and other non-ferrous metals, melted ditch and other materials made of quartz sand ramming,
