The invention discloses a ramming mass for an air-supplying blowpipe of a blast furnace and a forming method thereof. The ramming mass is prepared from the following raw materials in parts by weight: 65-75 parts of water granulated slag, 20-24 parts of high-temperature cement, 6-10 parts of fire-resistant clinker powder and 5-12 parts of water. The forming method for the ramming mass comprises the following steps: inclining a to-be-prepared blowpipe for 40-50 degrees, closing the lower end of the blowpipe and putting the blowpipe into a mould, wherein the taper at 0.5-1 degree on the mould is required and the surface of the mould is wrapped with the separation material; weighing the water granulated slag, the high-temperature cement and the fire-resistant clinker powder at the ratio of formula, adding the water granulated slag, the high-temperature cement and the fire-resistant clinker powder into water and mixing and stirring for 3-5min until the mixture is uniform; feeding the uniformly mixed materials into the blowpipe, ramming the material to be compact while feeding, till forming the whole blowpipe, extracting the mould and repeating the preparation for the next blowpipe; standing by the formed blowpipe for 5-9 days at room temperature. The blowpipe prepared according to the forming method provided by the invention has the advantages of excellent thermal insulation property, easy removal after slag pouring, convenience in manufacturing, no requirement for baking, low production cost, short period and higher popularization and application value.
