镁碳砖

详细介绍

修改_0000_DSC06068_副本.jpg

镁碳砖是以高熔点碱性氧化物氧化镁(熔点2800℃)和难以被炉渣侵润的高熔点碳素材料作为原料,添加各种非氧化物添加剂。用炭质结合剂结合而成的不烧碳复合耐火材料。镁碳砖主要用于转炉、交流电弧炉、直流电弧炉的内衬,钢包的渣线等部位。

镁碳砖作为一种复合耐火材料,有效地利用了镁砂的抗渣侵蚀能力强和碳的高导热性及低膨胀性,补偿了镁砂耐剥落性差的最大缺点。

其主要特点有:具有良好的耐高温性能,抗渣能力强,抗热震性好,高温蠕变低。


MgO-C brick is a kind of high melting point basic oxide magnesium oxide (2800 ℃) and high melting point carbon material which is difficult to be infiltrated by slag as raw materials, adding various non oxide additives. The unburned carbon composite refractories are made of carbon binder. Magnesia carbon brick is mainly used for lining of converter, alternating current arc furnace, direct current arc furnace, slag line of ladle, etc.

As a kind of composite refractories, magnesia carbon brick effectively utilizes magnesia's strong slag corrosion resistance, high thermal conductivity and low expansion of carbon, and compensates for the biggest disadvantage of magnesia's poor spalling resistance.

Its main characteristics are: good high temperature resistance, strong slag resistance, good thermal shock resistance, low high temperature creep.
