Magnesium-manganese-iron-aluminum composite spinel refractory material for cement kiln firing zone and preparation method of magnesium-manganese-iron-aluminum composite spinel refractory material
The invention belongs to the technical field of refractory products for cement kilns, and relates to a refractory brick, in particular to a magnesium-manganese-iron-aluminum composite spinel refractory material for a cement kiln firing zone and a preparation method of the magnesium-manganese-iron-aluminum composite spinel refractory material. The refractory material comprises the following raw materials in percentage by weight: 60-65% of magnesia particles, 30-35% of magnesia fine powder, 5-25% of manganese-iron-aluminum composite spinel powder and 3-5% of a binding agent. The preparation method comprises the following steps: weighing the following component raw materials in percentage by weight, adding the raw materials into a mixer for mulling for 20-30 minutes, molding on press machines with different tonnages according to the shape and piece weight of a product, drying a molded green body at 110 DEG C for 24 hours, firing at 1550-1650 DEG C for 8 hours, and naturally cooling. The magnesium-manganese-iron-aluminum composite spinel refractory material for the cement kiln firing zone produced by the invention has excellent kiln coating hanging property and thermal shock resistance, and the production and use processes of the refractory material have no strict requirements on atmosphere and are easy to control.
本发明属于水泥窑用耐火制品技术领域，涉及一种耐火砖，特别涉及一种水泥窑烧成带用镁锰铁铝复合尖晶石耐火材料及其制备方法。按重量百分比计，该耐火材料的原料组成为：镁砂颗粒60～65%，镁砂细粉30～35%，锰铁铝复合尖晶石粉5～25%，结合剂3～5%。制备方法如下：按重量百分比称量以下各组分原料，将各种原料加入混料机中进行混练20～30分钟，根据制品的形状及单重选择在不同吨位的压力机上成型，成型的坯体在110℃下干燥24 h，进行1550℃～1650℃×8 h烧成，自然冷却。本发明生产的水泥窑烧成带用镁锰铁铝复合尖晶石耐火材料有着优异的挂窑皮性和抗热震性，这种耐火材料生产和使用过程对气氛要求不严格，容易控制。
