High-calcium magnesia-calcium brick and preparation method thereof
The invention belongs to the technical field of refractory materials for smelting furnaces of special steel such as stainless steel, and particularly relates to a high-calcium magnesia-calcium brick and a preparation method thereof. 1-2 parts of natural dolomite with the particle size of 2-5mm; 1-2 parts of natural dolomite with the granularity of 200-300 meshes; 45-52 parts of synthetic magnesia-calcium sand with the particle size of 3-1mm; 35-55 parts of synthetic magnesia-calcium sand with a particle size of 2-5 mm; 60-82 parts of synthetic magnesia-calcium sand with the particle size of 200-300 meshes; 5-18 parts of magnesia with a particle size of 3-1 mm; 1-5 parts of magnesia with a particle size of 2-5 mm; 6-8 parts of magnesia with the particle size of 200-300 meshes; and 2-6 parts of paraffin. The castable is high in thermal shock resistance, ideal in slag resistance, high-temperature strength, hydration resistance and erosion and erosion resistance and long in service life.
本发明属不锈钢等特种钢冶炉用耐火材料技术领域，尤其涉及一种高钙镁钙砖及其制备方法，包括：粒度为3～1mm的天然白云石1～2；粒度为2～5mm的天然白云石1～2；粒度为200～300目的天然白云石1～2；粒度为3～1mm的合成镁钙砂45～52；粒度为2～5mm的合成镁钙砂35～55；粒度为200～300目的合成镁钙砂60～82；粒度为3～1mm的镁砂5～18；粒度为2～5mm的镁砂1～5；粒度为200～300目的镁砂6～8；石蜡2～6。本发明热震稳定性高，抗渣性、高温强度、抗水化性及抗侵蚀冲刷性理想，使用寿命长。
