The invention relates to a blast furnace taphole clay mixture. The blast furnace taphole clay mixture comprises the following components in parts by weight: 15-25 parts of aluminum-chrome spinel, 5-10 parts of yttrium mullite, 15-20 parts of coal gangue raw ore, 15-20 parts of coal gangue calcined cooked mine, 5-15 parts of composite clay, 10-30 parts of magnesia-hercynite powder, 10-30 parts of carbon resistance material powder, 10-15 parts of vanadic oxide, 5-8 parts of asphalt powder, 1-2 parts of nano-cellulose, 12-14 parts of an additional binding agent, and 5-15 parts of a thickening agent. Through the adoption of the blast furnace taphole clay mixture, a tapping hole is maintained, the production of a blast furnace is normal, and the taphole clay price is reduced, so that the cost is reduced for both an enterprise and a user, and the problems that a blast furnace front taphole becomes shallow, the taphole clay is polluted seriously and the cost is high in the prior art are completely solved.
