Castable for swinging launder of blast furnace tapping channel and preparation method of castable
The invention provides a castable for a swinging launder of a blast furnace tapping channel and a preparation method of the castable. The castable comprises the following components in parts by weight: 45-68 parts of a high-aluminum material, 10-18 parts of silicon carbide, 5-15 parts of andalusite, 2-4 parts of pure calcium aluminate cement, 0.1-0.3 part of a dispersing agent and 10-20 parts of a composite additive. By means of the swing chute lining body, the problems that an existing common swing chute lining body is low in impact corrosion resistance, shorter than a main channel in service life, frequent to repair and replace and the like can be solved.
本发明提供一种高炉出铁沟摆动流槽用浇注料及其制备方法，其中的浇注料按重量份计组成包括：高铝材料45～68份、碳化硅10～18份、红柱石5～15份、纯铝酸钙水泥2‑4份、分散剂0.1～0.3份，以及复合添加剂10～20份。利用本发明，能够解决现有的常用摆动溜槽衬体抗冲击蚀损性能低、使用寿命短于主沟、修补更换频繁等问题。
