Anti-erosion ladle magnesia carbon brick taking calcium magnesium aluminate as additive and preparation method thereof
The invention relates to an anti-erosion ladle magnesia carbon brick taking calcium magnesium aluminate as an additive and a preparation method thereof. The anti-erosion ladle magnesia carbon brick iscomposed of fused magnesia, calcium magnesium aluminate powder, graphite, carbon black and other raw materials, and also comprises a binding agent phenolic resin. According to the invention, a smallamount of CaO is introduced into a matrix by using calcium magnesium aluminate, CaO in calcium magnesium aluminate is combined with calcium aluminate, the sensitivity to water is low, calcium magnesium aluminate particles are mainly composed of magnesium aluminate spinel microcrystals embedded in a calcium aluminate phase, the slag corrosion resistance and permeability of the magnesia carbon brickare improved, the service life of the magnesia carbon brick is prolonged, a turnover rate of a steel ladle is increased, and a production cost is reduced.
本发明涉及一种以钙镁铝酸盐为添加剂的抗侵蚀钢包镁碳砖及其制备方法，所述镁碳砖由电熔镁砂、钙镁铝酸盐粉末、石墨、炭黑等原料组成，另外包括结合剂酚醛树脂。本发明使用钙镁铝酸盐将少量的CaO引入到基质中，钙镁铝酸盐中的CaO与铝酸钙相结合，对水的敏感度小，钙镁铝酸盐颗粒主要由嵌入在铝酸钙相中的镁铝尖晶石微晶构成，改善了镁碳砖的抗渣侵蚀和渗透性，从而提高了镁碳砖的使用寿命，增加了钢包的周转率,降低了生产成本。
