熔铝用无芯工频感应炉炉衬寿命的探讨

石英砂固有良好的热稳定性，较高的机械性能，较小的热膨胀系数，价格低廉等优点，被广泛用做中小型感应炉的炉守材料，从工频炉熔炼铝合金的工艺特点及对材料性能要求着手，分析了石英砂颗粒配比，打结，烧结对炉衬寿命的影响，用于生产，取得了较满意的效果。

Research of Lining Life of Coreless Power Frequency Induction Furnace for Aluminium Alloy Smelting

With good thermal stability, high mechanical properties, low thermal expansionand low price, quartz sands are widely used for Lining materials in some induCtion furnaces. But there is nearly no report about aluminium alloy smelting in the induction furnaces.The effect of contents, tamping and sintering of quartz sands on the lining life are analyzedfrom the wayS of process charaCters of aluminium alloy smelting in the induction furnacesand the properties of lining materials. Good results in production are gotten.
