Low-cost and long-life tundish slag line dry material
The invention discloses a tundish slag line dry material with low cost and long service life, and relates to the field of refractory materials, the tundish slag line dry material comprises the following raw material components by mass: 13-15% of 5-3mm magnesia carbon brick particles, 27-29% of 3-1mm 94 fused magnesite, 22-24% of 1-0mm 95 fused magnesite, 16-18% of 200-mesh 96.3 fused magnesite, 6-7% of 325-mesh magnesite-chrome brick powder, 2-3% of 200-mesh 87 alumina, 3-4% of phenolic resin and 0.1-0.3% of borax. The magnesia carbon brick particles are used for the slag line part of the working layer of the tundish of the T-shaped square billet. The prepared dry material has excellent erosion resistance and relatively low cost, the service life of the dry material on a T-shaped square billet tundish exceeds 60 h, and the service life is long.
本发明公开了一种低成本、长寿命中间包渣线干式料，涉及耐火材料领域，其原料组份质量百分比为：5‑3mm的镁碳砖颗粒为13～15%，3‑1mm的94电熔镁砂为27～29%，1‑0mm的95电熔镁砂为22～24%，200目的96.3电熔镁砂为16～18%，325目的镁铬砖粉为6～7%，200目的87矾土为2～3%，酚醛树脂为3～4%，硼砂为0.1～0.3%，余量为8‑5mm的镁碳砖颗粒，用于T型方坯中间包工作层渣线部位。本发明制备的干式料具备优异的抗侵蚀性能，且相对成本较低，在T型方坯中间包上使用寿命超过60h，使用寿命长。
