Siliceous anhydrous stemming for protecting blast furnace hearth
The invention relates to siliceous anhydrous stemming for maintaining a blast furnace hearth, the formula of the siliceous anhydrous stemming comprises an aggregate part and a matrix part, the aggregate part comprises high-silicon pyrophyllite, silicon carbide and coke; the matrix part comprises high-silicon pyrophyllite powder, silicon carbide powder, calcined activated aluminum oxide micro powder, ball clay, metal silicon powder, kyanite powder, a high-titanium substance, iron-silicon nitride, titanium carbide, high-temperature asphalt and microcrystalline graphite micro powder. The method has the advantages that the defects that a blast furnace operation process of a traditional titanium protection furnace must be adjusted, hearth accumulation and molten iron adhesion are prone to occurring are overcome, and the function of maintaining the hearth can be achieved under the conditions of normal blast furnace operation and tapping.
本发明涉及一种用于维护高炉炉缸的硅质无水炮泥，其配方组成如下：骨料部分，基质部分，其中骨料部分包括高硅叶腊石，碳化硅，焦炭；基质部分包括高硅叶腊石粉，碳化硅粉，煅烧活性氧化铝微粉，球粘土，金属硅粉，蓝晶石粉，高钛物质，铁－氮化硅，碳化钛，高温沥青以及微晶石墨微粉。本发明的优点：克服了传统钛护炉所出现的高炉操作工艺必须进行调整、易出现炉缸堆积和铁水粘缸等弊端，在正常的高炉操作和出铁情况下就可以实现维护炉缸的功能。
