Anti-splashing anhydrous stemming and preparation method thereof
The invention relates to anti-splashing anhydrous stemming and a preparation method thereof. The anti-splashing anhydrous stemming comprises the following components in parts by weight: 25-35 parts of brown aluminum oxide; 10 to 15 parts of ferrotitanium nitride; 10 to 15 parts of Guangxi clay; 15-25 parts of silicon carbide; 5 to 10 parts of coke; 5-10 parts of aluminum oxide; 8 parts of kyanite; 10-15 parts of a binding agent; ferrotitanium nitride is decomposed into part of titanium nitride in the tapping process, part of titanium nitride is decomposed and then reacts with oxygen to generate titanium oxide, titanium nitride has high strength, titanium oxide has certain viscosity at the high temperature and can block part of air holes, and therefore the stemming is more compact; the influence of splashing and smoking caused by gas leakage during blast furnace tapping on the environment can be effectively inhibited; the anti-splashing anhydrous stemming provided by the invention has the characteristics of high strength, high viscosity, capability of blocking part of air holes, compactness and the like, can effectively inhibit splashing, smoking and the like caused by gas leakage during tapping, and is suitable for large-scale popularization and application.
一种防喷溅无水炮泥及其制备方法，本发明以重量份包括以下组分：棕刚玉25～35份；氮化钛铁10～15份；广西粘土10～15份；碳化硅15～25份；焦碳5～10份；氧化铝5～10份；蓝晶石～8份；结合剂10～15份；外加剂12～18份，本发明中氮化钛铁在出铁过程中分解成部分氮化钛，还有部分氮化钛分解后与氧反应生成氧化钛，氮化钛有较高的强度，氧化钛高温下有一定的粘度能堵塞部分气孔，使得炮泥更加密实，可以有效抑制高炉出铁时跑煤气造成的喷溅和冒烟对环境的影响；本发明提供的防喷溅无水炮泥具有强度高、粘度大、能堵塞部分气孔、更加密实等特点，能有效抑制出铁时跑煤气造成的喷溅和冒烟等，适合大范围的推广和应用。
