Preparation method of electric smelting hercynite
The invention relates to a preparation method of electric smelting hercynit. According to the invention, magnesia-hercynite for a cement kiln firing zone is obtained by taking light-burned magnesia powder, ferric oxide powder and industrial alumina powder as raw materials and carrying out the procedures of fine grinding, mixing, ageing, pelletizing, drying, electric melting, crushing and the likeon the raw materials. Compared with the prior art, the method provided by the invention overcomes the defects in the prior art, provides the preparation method of the magnesium hercynite sand with lowenergy consumption, low dust and excellent product quality, which belongs to the technical field of inorganic chemical engineering. According to the method, the light-burned magnesia powder, the ferric oxide powder and the industrial aluminum oxide powder which are wide in source, low in price and free of pollution are used as raw materials, and the hercynite product prepared through the electricmelting method is high in compactness, high in erosion resistance, good in kiln coating hanging performance and high in product recovery rate.
本发明以轻烧镁粉、三氧化二铁粉和工业氧化铝粉为原料，原料通过细磨、混合、困料、造球、干燥、电熔、破碎等工序，得到水泥窑烧成带用镁铁铝尖晶石。与现有技术相比，本发明方法克服现有技术不足，提供了一种低能耗、低粉尘且产品质量优异的镁铁铝尖晶石砂的制备方法，属于无机化工技术领域。本发明方法以来源广泛、价格低廉且没有污染的轻烧镁粉、三氧化二铁粉和工业氧化铝粉为原料，通过本发明电熔法制备的镁铁铝尖晶石产品致密度高、抗侵蚀性强、挂窑皮性能良好且产品回收率高。
