电熔镁砂生产工艺

电熔镁砂的生产工艺流程短而简单，但设备投入和资源消耗大。我国电熔镁砂产业多采用电弧炉熔融天然菱镁矿石制备电熔镁砂，生产工艺技术装备落后，功率低、容量小、效率低、自动化程度低，生产出的电熔镁砂产品品位不高，导致镁资源利用率低，环境污染严重。

镁砂的种类和性能介绍

烧结镁砂是天然菱镁矿石MgCo3经高温煅烧而得的烧结块，在经破碎，筛选而成。或者由海水或卤水制得的氢氧化镁在1450-1900℃下充分烧结而得到的氧化镁原料。通常所说的烧结镁砂是指以菱镁矿为原料煅烧而得的产品，由于镁砂的烧结温度高，烧结程度好，故烧结镁砂也称为死烧镁砂，以与轻烧氧化镁相区别。是生产普通镁砖和不定形耐火材料的原料。

镁碳砖是怎样烧制成的

用电熔镁砂(烧结镁砂)和鳞片石墨(主要是结晶完全的石墨)为原料，以树脂作结合剂配制加压，经热处理而成。
为提高抗氧化性，常加入金属等防氧化剂。镁碳砖在高温下使用时形成碳骨架结合，由于氧化镁和碳不产生互溶关系，故保留了原有组份的优良耐火性能。碳的热传导性好，热膨胀系数和弹性系数均低，能有效地防止高温剥落和渣渗透，不易发生结构剥落，大大改变了渣渗透所引起的变质结构剥落这一致命弱点。加之碳对炉渣的不润

电熔镁砂介绍

电熔镁砂是以优质镁砂为原料经过熔化而制成, 大石桥耐火材料英文名称fused magnesite。由菱镁矿、水镁矿或从海水中提取的氢氧化镁经高温煅烧而成。
系菱镁矿等镁质原料经高温处理达到烧结程度的产物的统称。用竖窑、回转窑等高温设备一次煅烧或二步煅烧工艺，以天然菱镁矿为原料烧制的镁砂称为烧结镁砂;以菱镁矿等为原料经电弧炉熔炼达到熔融状态冷却后形成的称为电熔镁砂;从海水中提取氧化镁制成的称为海水镁
