The present invention provides an anhydrous stemming for blast furnace. Its composition includes (wt%) coarse brown corundun 1-4%, fine brown corundum 2-5%, coarse mullite 7-15%, fine mullite 9-20%, coke powder 15-20%, clay 10-19%, silicon carbide 7-11%, sericite 5-8%, bitumen 2-4% and anthracene oil 15-25%. It has good working property, stable high temperature resistance, excellent caking property, quick agglutinating property, low ton-iron stemming consumption, low contraction rate and high strength, it can raise tap up-to-standard rate to 100% from original 61.5%, can raise production safety of blast furnace, and can raise smelting strength.
