Coil castable for intermediate frequency furnace and preparation method of coil castable
The invention discloses a coil castable for an intermediate frequency furnace and a preparation method of the coil castable, and belongs to the technical field of refractory materials for intermediate frequency induction furnaces. The refractory material comprises the following raw materials in parts by weight: 22-45 parts of fused quartz, 12-18 parts of corundum fine powder, 6-15 parts of alpha-Al2O3 micro powder, 4-8 parts of electric smelting M70 mullite fine powder, 1-3 parts of anti-burst fibers, 3-7 parts of magnesia fine powder, 3-5 parts of silicon dioxide, 5-8 parts of zirconium oxide and 4-6 parts of an inorganic binder. After the coil is poured, the coil is good in combination integrity, high in later strength and not prone to shrinkage, cracking and the like, the overall service life of the coil is prolonged, the coil can bear strong scouring of high-temperature flue gas and coal ash and violent fluctuation of the hearth temperature, and the service life of a furnace body can be remarkably prolonged.
本发明公开一种中频炉用线圈浇注料及其制备方法，属于中频感应炉用耐火材料技术领域，其包括以下重量份原料：熔融石英22‑45份、刚玉细粉12‑18份、α‑Al2O3微粉6‑15份、电熔M70莫来细粉4‑8份、防爆裂纤维1‑3份、镁砂细粉3‑7份、二氧化硅3‑5份、氧化锆5‑8份、无机结合剂4‑6份；本发明使得线圈浇注后与线圈结合的整体性好，后期强度高，不易产生收缩开裂等现象，提高了线圈的整体使用寿命，能够经受高温烟气和煤灰的强烈冲刷以及炉膛温度的剧烈波动，可显著提高炉体的使用寿命。
