摘　　要：研究了镁砂及烧成温度对镁质滑板高温性能的影响。结果表明 :以ω(MgO)≥ 98%、C/S≥ 3、晶粒直径≥ 5 0 0 μm的高纯镁砂为内层料 ,以中低档镁砂为外层料 ,用纸浆废液作结合剂 ,直接复合成型的镁质滑板经 16 5 0℃左右的高温烧成后 ,性能指标达到外商订货要求 ,不经浸油、打箍 ,在国外 385t连铸钢包批量试用成功。The effects of magnesia variety and sintering temperature on physical properties of the slide plate were studied.The plate was prepared using high purity magnesia with MgO ≥98%,CaO/SiO 2≥3,crystalline particle diameter≥500 μm as internal lining material,medium grade magnesia as external lining material and waste pulp as binder.The sintering temperature of the plate is about 1650 ℃.The properties of the plate meet the ordering requirement of the customers and it has been batchly used in 385 t ladle of abroad successfully.
