The invention discloses a taphole clay for blast furnaces. The invention is characterized in that the taphole clay for ironmaking is composed of the following components in parts by weight: 15-20 parts of 3-0mm Sialon, 5-8 parts of 1-0mm Bonite, 10-15 parts of 1-0mm sillimanite, 8-15 parts of 0.5-0 magnesium iron oxide, 8-13 parts of clay powder, 3-7 parts of cobalt aluminum oxide powder, 5-10 parts of cutting powder, 7-25 parts of graphite powder, 5-10 parts of composite carbon powder, 0-1 part of strontium carbonate powder and 1-2 parts of moderate-temperature asphalt powder. The taphole clay can keep the taphole diameter stable without changing easily, so that the tapping is stable. Besides, the service performance and operating performance of the taphole clay do not decrease in the long-term storage process.
