Abstract:

Adding Cr2O3 (0,1%,2% and 4%,in mass) to the experimental basic formulation of steel-tapping hole filling refractory, the effects of different Cr2O3 contents were discussed.The results show that the corrosion resistance increased obviously when Cr2O3 was added, and the bulk density and strength reduced a little.When Cr2O3 addition is 2%, the best comprehensive property was obtained.
