Microporous castable for steel ladle cover
The invention relates to the technical field of refractory materials, and particularly discloses a steel ladle cover microporous castable which comprises aggregate, powder and an additive, the aggregate comprises the following raw materials by weight percent: 21-26% of light-burned mullite particles, 17-22% of light-burned mullite particles, 8-13% of zirconium oxide hollow spheres and 8-13% of zirconium oxide hollow spheres, and the powder is powder. The powder material is prepared from the following raw materials in percentage by weight: 15 to 25 percent of floating beads, 5 to 8 percent of kyanite micro powder, 1 to 3 percent of silicon nitride, 5 to 8 percent of active aluminum oxide micro powder, 1 to 3 percent of silicon micro powder and 3 to 8 percent of CA-70 calcium aluminate cement, and the additive is prepared from the following raw materials in percentage by weight: 0.1 to 0.3 percent of sodium hexametaphosphate and 0.03 to 0.06 percent of explosion-proof fiber. The problems that a traditional steel ladle cover pouring material is high in thermal expansion coefficient and prone to expansion cracking, and consequently the service life of a ladle cover is affected are solved.
本发明涉及耐火材料技术领域，具体公开了一种钢包包盖微孔浇注料，包括骨料、粉料和外加料，骨料包括按以下重量百分比进行分配的原料：21～26％的轻烧莫来石颗粒、17～22％的轻烧莫来石颗粒、8％～13％的氧化锆空心球和8％～13％的氧化锆空心球，粉料包括按以下重量百分比进行分配的原料：15～25％的漂珠、5％～8％的蓝晶石微粉、1％～3％的氮化硅、5％～8％的活性三氧化二铝微粉、1％～3％的硅微粉和3％～8％的CA‑70铝酸钙水泥，外加料包括按以下重量百分比进行分配的原料：0.1～0.3％的六偏磷酸钠和0.03～0.06％的防爆纤维，解决了传统的钢包包盖浇筑料受热膨胀系数较高，存在容易膨胀开裂而影响包盖使用寿命的问题。
