Anhydrous carbonaceous hole plugging stemming material for ferroalloy furnace and preparation method of anhydrous carbonaceous hole plugging stemmingmaterial
The invention discloses an anhydrous carbonaceous hole plugging stemming material for a ferroalloy furnace and a preparation method of the anhydrous carbonaceous hole plugging stemming material. The anhydrous carbonaceous hole plugging stemming material comprises the following components: silicon nitride, silicon carbide, coke, asphalt, clay, an adhesive, a plasticizer, refractory adhesive mediumpowder, thermosetting phenolic aldehyde and an anhydrous carbonaceous adhesive. The preparation method comprises the following steps of: mixing the silicon nitride, silicon carbide, coke, asphalt, clay, refractory adhesive medium powder, thermosetting phenolic aldehyde and the anhydrous carbonaceous adhesive in proportion to form a mixture; uniformly stirring the mixture, adding the bulk materialinto a crusher, crushing and then drying the material; adding an adhesive agent and a plasticizer in proportion, performing stirring and detecting to obtain a product. The service cycle of the ferroalloy furnace can be greatly prolonged, and the service life of the ferroalloy furnace is prolonged. And meanwhile, long-time smooth operation of the condition of the furnace, and normal deslagging andcharring can be guaranteed, and the production index can be indirectly improved.
本发明公开了一种铁合金炉用无水碳质堵眼炮泥及其制备方法，该堵眼炮泥成分包括氮化硅，碳化硅，焦炭，沥青，黏土，附着剂，增塑剂，耐火胶介质粉末，热固性酚醛，无水碳质粘合剂。制备方法包括按比例混合氮化硅，碳化硅，焦炭，沥青，黏土，耐火胶介质粉末，热固性酚醛，无水碳质粘合剂形成混合物；搅拌均匀，将散料加入粉碎机先粉碎后干燥；按比例加入附着剂，增塑剂后搅拌，经检测后形成产品。本发明可大幅度提高铁合金炉使用周期，提高铁合金炉使用寿命。同时，可保证炉况长时间顺行，排渣、炭正常，可间接提高生产指标。
