Binder used before pouring of blast furnace tapping channel and preparation method thereof
The invention relates to the technical field of refractory materials, in particular to a binding material used before pouring of a blast furnace tapping channel sleeve and a preparation method of thebinding material. The silicon carbide ceramic comprises the following components in percentage by mass: 60-65% of alpha-Al2O3 micro powder, 23%-27% of metal silicon powder and 10.5-14.5% of boron carbide, and 250ml of silica sol is added into every 100g of the mixed components. According to the gunning mix for repairing iron runner pouring and the preparation method of the gunning mix, through thedesign of a binding material used before blast furnace tapping channel pouring, the problems that in the prior art, in an iron runner repairing mode adopting pouring, new materials and old materialsare not easy to combine, iron leakage accidents are likely to be caused, workers conduct construction many times, and the construction cost is high are solved. The technical problem of high labor intensity is solved.
本发明涉及耐火材料技术领域，尤其是涉及一种高炉出铁沟套浇前用结合料及其制备方法；按照质量计，包括α‑Al2O3微粉60‑65%、金属硅粉23%‑27%、碳化硼10.5‑14.5%，每100g上述混合成分添加250ml硅溶胶；本发明的目的在于提供一种用于修补铁沟套浇的喷补料及其制备方法，通过高炉出铁沟套浇前用结合料的设计以解决现有技术中存在的采用套浇的铁沟修补方式存在着新料与旧料不易结合，易造成漏铁事故，且工人多次施工，劳动强度大的技术问题。
