Preparation method of silicon firing crucible for induction furnace lining
The invention provides a preparation method of a silicon firing crucible for an induction furnace lining, and belongs to the field of high-temperature structural materials. Mining high-quality silicais used as a raw material and is crushed and screened to obtain materials of 8-6 mm, 5-4 mm, 3-2 mm, 1-0.074 mm and below 200 meshes, and the materials and a binding agent are mixed, formed, dried andsintered to obtain the silicon sintered crucible. Compared with the prior art, the furnace lining material of the silicon firing crucible prepared by the invention contains few impurities, so that the erosion resistance of the furnace lining material in the smelting process is remarkably improved, the erosion of high-temperature melt to the furnace lining material and slag is effectively prevented, the service life of an induction furnace is prolonged, and the thermal shock resistance of the material is improved to a great extent; the product quality is more stable and reliable, long-term stable production operation in the furnace is realized, the working efficiency is improved, and the profit of enterprises is increased.
本发明提供一种感应炉衬用硅质烧成坩埚的制备方法，属于高温结构材料领域。以矿山开采高品质硅石为原料，经破粉碎和筛分后，得到8‑6mm、5‑4mm、3‑2mm、1‑0.074mm、200目以下的物料，与结合剂经混炼、成型、干燥和烧成制得硅质烧成坩埚。与现有技术相比，使用本发明制备的硅质烧成坩埚的炉衬材料含有杂质含量少，显著提高其在熔炼过程中抗侵蚀能力，有效阻止高温熔体对其冲刷和熔渣的侵蚀，延长感应炉的使用寿命，并且很大程度上提高材料的抗热震能力，使产品质量更加稳定可靠，实现炉内长期稳定生产运转，提高工作效率而增加企业获利利润。
