Magnesium-iron-chromium brick for kiln car and preparation method of magnesium-iron-chromium brick
The invention belongs to the technical field of refractory materials, and particularly relates to a magnesium-iron-chromium brick for a kiln car and a preparation method of the magnesium-iron-chromium brick. The magnesium-iron-chromium brick for the kiln car is prepared from the following raw materials in percentage by weight: 40-70% of high-iron magnesite with the particle size of less than or equal to 4mm, 10-45% of hercynite with the particle size of less than or equal to 4mm, 5-30% of high-purity fused magnesite with the particle size of less than or equal to 4mm, 5-30% of chromium concentrate with the particle size of less than or equal to 1mm and a binding agent which accounts for 2-5wt% of the total weight of the raw materials. The preparation method of the magnesium-iron-chromium brick for the kiln car comprises the steps of burdening, mixing, forming after ageing, drying and sintering. The service life of the magnesium-iron-chromium brick for the kiln car exceeds 12 months, the production cost is greatly saved, meanwhile, due to the fact that the refractoriness under load of the magnesium-iron-chromium brick is high, the brick body is not prone to deformation, the stability of brick piles stacked on the kiln car is guaranteed, and the safety coefficient of kiln operation is improved.
本发明属于耐火材料技术领域，具体涉及一种窑车用镁铁铬砖及其制备方法。窑车用镁铁铬砖，以重量百分比计，由如下原料制备而成：粒度≤4mm的高铁镁砂40～70%，粒度≤4mm的铁铝尖晶石10～45%，粒度≤4mm的高纯电熔镁砂5～30%，粒度≤1mm的铬精矿5～30%，外加占上述原料总重2～5wt%的结合剂。所述窑车用镁铁铬砖的制备方法，包括配料、混炼、困料后成型、干燥和烧成。本发明的窑车用镁铁铬砖使用寿命超过12个月，极大的节省了生产成本，同时由于其荷重软化温度较高，砖体不易变形，也保证了窑车上码放的砖垛的稳固性，提高了窑炉运行的安全系数。
