Preparation method of high-thermal-shock chrome corundum brick for hazardous waste gasification melting furnace
The invention relates to the technical field of preparation of chrome corundum bricks, and discloses a preparation method of a high-thermal-shock chrome corundum brick for a hazardous waste gasification melting furnace, and the preparation method comprises the following steps: mixing and stirring corundum and chromic oxide; adding water, adjusting the water content of the mixture, continuously stirring, flattening and drying the mixture, and crushing into matrix aggregate particles with the particle size of 0.1-0.5 mm; mixing the clay powder and the andalusite powder, uniformly stirring, and adjusting the water content to obtain a surface dressing; putting matrix aggregate particles into the surface layer dressing, spreading out the mixture after stirring, and repeatedly forging the upper surface of the spread layer up and down; then carrying out air-drying at normal temperature; putting the above into a friction brick press, and forming a blank; and drying and then firing the obtained blank to obtain the chrome corundum brick. According to the invention, the thermal shock resistance of the chrome corundum brick can be effectively improved, and the service life of the chrome corundum brick refractory material is greatly prolonged.
本发明涉及铬刚玉砖制备技术领域，公开了一种用于危废气化熔融炉的高热震铬刚玉砖的制备方法，包括以下步骤：将刚玉与三氧化二铬混合搅拌；加水，调整混合物的含水率，持续搅拌后将混合物碾平烘干，再破碎成粒径为0.1～0.5mm的基质骨料颗粒；将粘土粉末、红柱石粉末混合，搅拌均匀，调节含水率，得到表层敷料；将基质骨料颗粒放入表层敷料中，搅拌后将混合物铺平，对铺层的上表面反复进行上下锻打；然后常温风干；放入摩擦压砖机中，坯料成型；得到的坯料进行干燥，然后烧制，得到铬刚玉砖；本发明能够有效提高铬刚玉砖的热抗震性能，大大提高铬刚玉砖耐火材料的使用寿命。
