钢包用镁铝碳滑板的研究与应用

Study and application of magnesium aluminum carbon slide gate for steel ladle

根据钙处理钢的侵蚀机理,选用抗侵蚀性良好的优质镁砂和尖晶石,适量加入低膨胀添加剂和金属添加剂,选用改性酚醛树脂作结合剂,经过中温烧成,制成了镁铝碳滑板。这种滑板具有抗侵蚀、低膨胀、抗热震性良好等优点,在钢厂使用,其平均使用寿命可达4次以上。

Based on erosion mechanism of calcium treatment steel,magnesium aluminum carbon slide gate was fired in medium temperature with high quality magnesia and spinel with good erosion resistance as raw materials,adding low expansion additives and metal additives in appropriate amounts and modified phenolic resin as a binder.This kind of slide gate has the advantages of good erosion resistance,low expansion and thermal shock resistance,the average service life can reach more than 4 times in steel mills.
