The anti-oxidation performance of castable for blast furnace iron ditch is an important index to determine the service life of castable.In order to improve the problem of easy oxidation of castable for iron ditch,the original formula of castable for iron ditch is prepared with brown corundum,silicon carbide,alumina,silicon powder,cement and carbon as raw materials,and the influence law of new antioxidant aluminum titanium carbide on the anti-oxidation performance and other physical indexes of castable is studied.The results show that the normal temperature strength of the material decreases gradually with the increase of antioxidant aluminum titanium carbide.The strength of the material after medium temperature and high temperature treatment increases first and then decreases.The high temperature flexural strength increases first and then decreases,and the oxidation resistance increases gradually.When the addition amount of Ti3AlC2 is 1％,the comprehensive index of the material is the best.
