Light heat insulation type tundish permanent layer castable
The invention discloses a light heat insulation type tundish permanent layer castable, which is prepared from the following raw materials in parts by weight: 50 to 70 parts of mullite light aggregate, 20 to 35 parts of high bauxite powder, 5 to 15 parts of aluminum oxide micro powder, 5 to 15 parts of silicon dioxide micro powder, 10 to 15 parts of aluminate cement, 0.5 to 3.0 parts of steel fiber, 0.1 to 0.5 part of anti-explosion fiber and 0.1 to 0.5 part of a water reducing agent. The castable has the beneficial effects that the castable is simple in preparation process and convenient to prepare, the castable is used for manufacturing a tundish, the existing heavy tundish can be replaced, the temperature of the outer surface of a tundish steel shell is effectively reduced, and the steelmaking cost is also effectively reduced.
本发明公开了一种轻质隔热型中间包永久层浇注料，其配置原料包括莫来石质轻质骨料、高铝矾土粉、三氧化二铝微粉、二氧化硅微粉、铝酸盐水泥、钢纤维、防爆纤维、减水剂，配制原料的重量份为：莫来石质轻质骨料50‑70份，高铝矾土粉20‑35份，三氧化二铝微粉5‑15份，二氧化硅微粉5‑15份，铝酸盐水泥10‑15份，钢纤维0.5‑3.0份，防爆纤维0.1‑0.5份，减水剂0.1‑0.5份。本发明的有益效果是，此浇注料配制过程简单，便于配制，运用该浇注料制作中间包，可以替代现有的重质中间包，有效降低中间包钢壳外表面温度，同时，也有效降低了炼钢的成本。
