Silica fume-free refractory castable for iron runner and preparation method of silica fume-free refractory castable
The invention relates to a silica fume-free refractory castable for an iron runner and a preparation method of the silica fume-free refractory castable. The silica fume-free refractory castable comprises the following components in parts by weight: 30-40 parts of brown fused alumina, 20-30 parts of compact corundum, 20-25 parts of silicon carbide, 10-15 parts of a silica fume-free binding agent and 5-8 parts of an additive. Through the structural design of the silica-fume-free refractory castable for the iron runner, the technical problems that an existing silica-fume-free refractory castable for the iron runner in the prior art is poor in erosion resistance and flowability in a high-temperature using process, and the service life of the iron runner is short are solved.
本发明涉及一种出铁沟用无硅灰耐火浇注料及其制备方法；按照重量份数计，包括棕刚玉30‑40份、致密刚玉20‑30份、碳化硅20‑25份、无硅灰结合剂10‑15份和添加剂5‑8份；通过出铁沟用无硅灰耐火浇注料的结构设计以解决现有技术中存在的现有的硅灰铁沟耐火浇注料，高温使用过程中抗侵蚀性、流动性差，出铁沟使用寿命短的技术问题。
