The invention discloses environment-friendly anhydrous stemming for a blast furnace. The environment-friendly anhydrous stemming is prepared from a high-aluminum material, a recycled iron runner material, coke breeze, silicon carbide powder, ferrosilicon nitride powder, kyanite powder, Guangxi white mud powder and an additional binding agent according to a certain weight part ratio and particle size gradation. The formula of the anhydrous stemming is scientific and environment-friendly; the stemming is low in shrinkage rate, high in strength and excellent in scouring resistance and erosion resistance, the one-time tapping time can reach 120-150 minutes, and iron tapping time of the stemming is prolonged. A part of recycled scrap iron channel material is added, so that the raw material costis reduced; through waste recycling, consumption of raw materials is reduced, and energy is saved; and the silicon nitride iron is added, so that the erosion resistance of the finished anhydrous stemming is improved. The binding agent is prepared from carbon-containing resin and phenolic resin, so that the pollution of stemming is reduced, and the generation of cancerogenic substances is reduced.The product improves the stokehole operation environment of the blast furnace and achieves the purpose of environmental protection.
