Low-carbon magnesia-carbon refractory material and preparation method thereof
The invention relates to the field of refractory materials, in particular to a low-carbon magnesia-carbon refractory material and a preparation method thereof. The low-carbon magnesia-carbon refractory material is prepared from, by weight, 79-91 parts of magnesia (the content of MgO is larger than 97 wt%), 3-8 parts of carbon, 3-5 parts of a binding agent and 3-8 parts of magnesium borate whiskers. A magnesium borate whisker material with the diameter of 50-5000 nm and the length of 200-20000 nm is added in the process of preparing the low-carbon magnesia carbon refractory material, so that the oxidation resistance of the low-carbon magnesia carbon refractory material is improved. The method is simple in production process and low in energy consumption, the oxidation resistance of the low-carbon magnesia-carbon refractory material can be greatly improved, and the service life of the magnesia-carbon refractory material is prolonged.
本发明涉及耐火材料领域，具体涉及一种低碳镁碳耐火材料及其制备方法，由以下重量份数的原料制备而成：镁砂(MgO含量大于97wt％)79～91份、碳素3～8份、结合剂3～5份、硼酸镁晶须3～8份。在制备低碳镁碳耐火材料过程中添加直径50～5000nm、长度200～20000nm的硼酸镁晶须材料，以提高低碳镁碳耐火材料的抗氧化性能。本发明所述方法生产工艺简单，能耗低，可大幅提高低碳镁碳耐火材料的抗氧化性能，延长镁碳耐火材料的使用寿命。
