Ferro silicon Nitride

Application of ferro silicon nitride in anhydrous taphole clay: At present, submerged arc furnaces still generally use traditional anhydrous taphole clay, which uses al2o3-sic-c as the main material and ordinary coal tar as the binder, because it cannot resist The long-term infiltration and erosion of high-temperature slag and molten iron makes it impossible to maintain a reasonable tap hole depth during use, and often occurs that the tap hole cannot be drilled, smoke is emitted from blocked ports, and toxic and harmful gases are emitted, endangering the environment.

Product advantages of ferro silicon nitride: In order to improve the shortcomings of anhydrous taphole mud for submerged arc furnaces, more and more customers use chromium-containing plastics to block the iron holes on large submerged arc furnaces, which not only cannot change The depth of the tap hole is shallow, and it is more likely to cause leakage of the tap hole and difficulty in opening the tap hole. It is forced to burn the oxygen pipe, destroying the mud bag structure of the tap hole, and significantly increasing the labor intensity and smelting cost of the furnace front workers. Especially when submerged arc furnaces are smelted with low-level electrodes at high temperature, the depth of the taphole is significantly shortened, the temperature of the furnace wall rises, and the phenomenon of serious damage to the taphole flange often occurs.
Environmentally-friendly anhydrous taphole clay produced based on ferro silicon nitride has good plasticity, easy to mud, strong resistance to high temperature slag penetration and erosion, easy to open the iron hole to meet the low electrode, higher temperature, higher slag Proportion submerged arc furnace smelting process requirements.
