该砂是备选高级菱镁石或高级轻烧镁粉为塑料原食材在焊弧炉中高溫熔融而成。方镁石生长成熟的、纳米线大、一直相结合率高、形式非均质、抗渣性强、高溫体型大小保持稳定得天独厚。是生产方式镁碳砖、咸性砖和不成形耐火食材的好塑料原食材,按MgO含量的96-98%分会员等级。lt is produced by fusion in the electric are furnace with high temperature with superior magnesite or superior light burned magnesite powder as raw materials. Periclase develops completely and its crystal is big.with high combination rate, firm and tight structure, good refuses resistance and stable,good high temperature volume. lt is good raw material to produce magnesia carbon bricks,high-class magnesia bricks and unshaped refractory materials.Grades are classified according to MgO content 96%-98%.
