Forsterite composite brick and preparation method thereof
The invention discloses a forsterite composite brick which is composed of a working layer and an insulating layer. The working layer takes magnesium iron sand, hercynite sand and fused magnesite as main raw materials, and the insulating layer is prepared from medium-heavy synthetic forsterite sand, medium-light synthetic magnetite sand, corundum particles, fine magnesium powder and rice hull ash through the steps of burdening, mixing, forming, drying and firing. The working layer of the composite brick has relatively strong corrosion resistance and good thermal shock stability, is easy to adhere to the kiln wall and has low thermal conductivity, and the insulating layer has good high-temperature volume stability, high mechanical strength and low thermal conductivity. Therefore, the composite brick can be used in a high-temperature area of a rotary cement kiln and is long in service life. And the heat dissipation loss of the kiln body can be obviously reduced, and good energy-saving and emission-reducing effects are achieved.
本发明公开了一种镁橄榄石复合砖，由工作层和绝缘层组成。工作层以镁铁质砂、铁铝尖晶石砂和电熔镁砂为主要原料，绝缘层由中重合成镁橄榄石砂、中轻合成镁橄石砂、刚玉颗粒、细镁粉和稻壳灰通过配料、混合、成型、干燥和烧制步骤制成。本发明的复合砖的工作层具有较强的耐腐蚀性、良好的热冲击稳定性、易粘在窑壁上、导热性低，绝缘层具有良好的高温体积稳定性、高机械强度和低导热性。因此，该复合砖可用于水泥回转窑的高温区，使用寿命长。可显著降低窑体散热损失，具有良好的节能减排效果。
