Carbon-free corundum-spinel unburned brick for steel ladle and preparation method of carbon-free corundum-spinel unburned brick
The invention discloses a carbon-free corundum-spinel unburned brick for a steel ladle and a preparation method of the carbon-free corundum-spinel unburned brick. The preparation method comprises the following working steps: step 1, obtaining a mixture I; step 2, obtaining a mixture II; step 3, obtaining a mixture III; step 4, mixing the mixture II and the mixture III, adding 5-15 parts of electric smelting calcium magnesium aluminate CMA particles, mixing for 20-30 minutes, and discharging to obtain a mixture IV; and step 5, the mixture IV is subjected to mechanical pressing molding, and the carbon-free corundum-spinel unburned brick is prepared. The carbon-free corundum-spinel unburned brick has the beneficial effects that the product is carbon-free, environment-friendly, free of sintering treatment and good in volume stability and thermal stability, and the prepared carbon-free corundum-spinel unburned brick is large in volume density, low in apparent porosity, good in normal-temperature and high-temperature mechanical properties, controllable in linear change rate, good in thermal shock stability, long in service life and capable of meeting the production requirements of (ultra) low-carbon steel.
本发明公开了一种钢包用无碳刚玉‑尖晶石不烧砖及其制备方法，包括以下工作步骤：步骤一、得到混合料Ⅰ；步骤二、得到混合料Ⅱ；步骤三、得到混合料Ⅲ；步骤四、将所述混合料Ⅱ和混合料Ⅲ混合后，外加电熔钙镁铝酸盐CMA颗粒5~15份，混炼20~30分钟后出料，得到混合料Ⅳ；步骤五、将所述混合料Ⅳ机压成型，制得所述无碳刚玉‑尖晶石不烧砖；有益效果是，产品无碳、环保、无需烧结处理、体积稳定性和热稳定性好，所制备的无碳刚玉‑尖晶石不烧砖体积密度大、显气孔率低、常温及高温力学性能好、线变化率可控、热震稳定性好、使用寿命长、可满足（超）低碳钢的生产需求。
