兰晶石是一种高铝矿物原料,具有在高温下一次性膨胀的特性,同时转变成富铝红柱石,耐火温度高于1800℃。它还具有强度大、抗磨、抗温度急变和抗化学腐蚀等特点。在现代冶炼工艺的不定形耐火材料及技术陶瓷、硅铝合金的配制和生产中,占有十分重要的地位。待上海宝钢总厂投产后,每年所需兰晶石原料量很大。 Galanite is a high-alumina mineral that has the property of one-time swelling at high temperatures and is converted to mullite with a refractory temperature above 1800 ° C. It also has the strength, anti-wear, anti-temperature resistance and chemical resistance and other characteristics. In the modern smelting process of amorphous refractory and technical ceramics, silicon aluminum alloy preparation and production, occupies a very important position. After the Shanghai Baosteel Plant is put into production, the annual amount of blue spar is very large.
