| Abstract: | In order to make submerged arc furnace operate smoothly, optimized and improved the texture and recipe of stemming. Through the use of high-purity matrials with different nonoxide and organic binder, the stemming has good sinterability, erosion resistance, fillibility, and easy to open taphole, meanwhile, bonding strength between new and old stemming is high. Therefore, taphole stability of submerged arc furnace has been improved, smooth operation, low consumption, safety and long working life have been achieved. |
