Carbon-containing refractory mortar for refining steel ladle and preparation method of carbon-containing refractory mortar
The invention relates to the field of refractory materials and unshaped refractory material products, and discloses carbon-containing refractory mortar for refining a steel ladle and a preparation method of the carbon-containing refractory mortar. The carbon-containing refractory mortar for refining the steel ladle comprises the following raw materials: 96 high-purity magnesite I, 96 high-purity magnesite II, colloidal graphite, silicon carbide micro powder, silicon dioxide, yellow dextrin, carboxymethyl cellulose, sodium tripolyphosphate and sodium hexametaphosphate, the colloidal graphite is introduced on the basis of magnesian steel ladle fire clay, and meanwhile, the 96 high-purity magnesite is used for replacing fused magnesite fine powder, so that the carbon-containing refractory mortar is prepared. The carbon-containing refractory mortar with high bonding strength, high temperature resistance and excellent erosion resistance is developed by adding yellow dextrin, carboxymethyl cellulose, silicon carbide micro powder, silicon dioxide, sodium tripolyphosphate and sodium hexametaphosphate, and the problem that brick joints are most easily eroded in the application of steel ladles is solved.
本发明涉及耐火材料和不定型耐火材料制品领域，公开了一种精炼钢包用含碳耐火泥及其制备方法，精炼钢包用含碳耐火泥包括以下原料：96高纯镁砂一、96高纯镁砂二、胶体石墨、碳化硅微粉、二氧化硅、黄糊精、羧甲基纤维素、三聚磷酸钠、六偏磷酸钠,通过在镁质钢包火泥基础上，引入胶体石墨，同时使用96高纯镁砂替代电熔镁砂细粉，添加黄糊精、羧甲基纤维素、碳化硅微粉、二氧化硅、三聚磷酸钠、六偏磷酸钠，研制成一种粘结强度高、耐高温和抗侵蚀性能优异的含碳耐火泥，解决了钢包在应用中砖缝最容易被侵蚀的问题。
