Tap hole filler for electric furnace with high self-opening rate
The invention discloses a tapping hole filling material for an electric furnace with a high self-opening rate, and relates to the field of refractory materials, the tapping hole filling material comprises the following components by weight: 30%-40% of raw olive sand particles, 50%-60% of regenerated magnesite-chrome brick particles, 1%-10% of fused magnesia fine powder and 1%-5% of crystalline flake graphite, the tapping hole filling material prepared by the invention is higher in self-opening rate, and the self-opening rate of the tapping hole filling material is higher. The production cost is low, the strength is high, the erosion resistance is good, and the market competitiveness is improved.
本发明公开了一种高自开率电炉用出钢口填充料，涉及耐火材料领域，出钢口填充料按重量百分比，包括如下组分：生橄榄砂颗粒30％～40％，再生镁铬砖颗粒50％～60％，电熔镁砂细粉1％～10％，鳞片石墨1％～5％，本发明制备的出钢口填充料自开率更高，生产成本低，强度高，抗侵蚀性能好，提高了市场竞争力。
