Low-carbon magnesia carbon brick for ladle slag line and preparation method thereof
The invention discloses a low-carbon magnesia carbon brick for a ladle slag line. The brick comprises a fan-shaped brick body, wherein the inner side surface and the outer side surface of the fan-shaped brick body are arc-shaped surfaces, and the first side surface and the second side surface of the fan-shaped brick body are wavy. Due to the appearance structure of the brick, stacking difficulty can be reduced and stability after stacking is improved; heat insulation holes are formed in the lower bottom surface of the fan-shaped brick body, so the heat conductivity coefficient of the low-carbon magnesia carbon brick is reduced, the loss of heat is reduced, and important significance is achieved in the aspect of stabilization of molten steel temperature; and positioning blocks are formed onthe upper surface of the fan-shaped brick body, so more labor is saved and the stabilizing effect is better in the stacking process. The invention further discloses a preparation method of the low-carbon magnesia carbon brick for the ladle slag line. High-activity metal composite powder is added into a magnesia carbon alkaline material, and a carbon content is reduced to 5% or below from 10%-18%,so while good thermal shock stability and high-temperature strength are kept, oxidation resistance and slag resistance are improved, and requirements of clean smelting are met.
本发明公开了一种钢包渣线用低碳镁碳砖，其包括有扇形砖体，其内侧面与外侧面均为弧形面，其第一侧面和第二侧面为波浪形状，其外形结构能够减少堆砌难度，以及提高堆砌后的稳固度，其下底面开设有隔热孔，从而降低了低碳镁碳砖的导热系数，减少了热量的损失，对于稳定钢水温度具有重要意义，其上表面成型有定位块，在堆砌过程中更加省力且稳固效果更好，一种钢包渣线用低碳镁碳砖的制备方法，采用高活性金属复合粉加入到镁碳碱性材料中，碳含量由10％～18％降到5％以下，保持良好的热震稳定性和高温强度，提高抗氧化性和抗渣性，适应洁净冶炼的需要。
