用石英砂混合料修理冲天炉炉壁,是挖掘冲天炉潜在能力和提高熔化量的重要手段。我厂三吨冲天炉改用石英砂混合料修炉后,熔化能力从每天二十多吨提高到五十二吨,修炉一次可连续熔化达十六小时以上。石英砂混合料的配合成分为:石英砂 Quartz sand mixture used to repair cupola furnace wall, is to tap the potential capacity of the cupola and improve the melting of an important means. I plant three tons of cupola switch to quartz sand mixture repair furnace, the melting capacity from more than 20 tons per day increased to 52 tons, repair furnace can be a continuous melting for more than sixteen hours. Quartz sand mixture with ingredients: quartz sand
