Tundish slag wall castable and preparation method thereof
The invention relates to a tundish slag wall castable and a preparation method thereof. The refractory material comprises the following components in parts by weight: 30-40 parts of dead burnt magnesia, 45-56 parts of medium-grade magnesia, 3-6 parts of fused quartz, 3-6 parts of ferro-silicon nitride, 3-5 parts of silica powder and 2-3 parts of an additive containing boron carbide, through the structural design of the tundish slag wall castable and the preparation method thereof, the technical problems that in the prior art, a tundish slag wall castable is not resistant to erosion, low in normal-temperature strength and not suitable for smelting low-carbon steel are solved.
本发明涉及一种中间包挡渣墙浇注料及其制备方法；按照重量份数计，包括重烧镁砂30‑40份、中档镁砂45‑56份、熔融石英3‑6份、氮化硅铁3‑6份、硅微粉3‑5份和含有碳化硼的添加剂2‑3份；通过本发明涉及的中间包挡渣墙浇注料及其制备方法的结构设计以解决现有技术中的中间包挡渣墙浇注料的不抗侵蚀、常温强度低、不适宜冶炼低碳钢的技术问题。
