Method for manufacturing blast furnace stemming

A preparation method for blast furnace taphole clay has the following processes, bulk raw materials are heated to 20 to 40 DEG C and are mixed evenly, the particle size of the bulk raw materials is 3 to 0.074mm, binder is then added, the mixture is grinned for 40 to 60 minutes, which is then pressed and formed, the additive and each bulk raw material are put into separate holding tank, the binderis put into a holding tank, the raw material is heated to 20 to 40 DEG C in the holding tank, binder is added into the clay mill to be grinned for 40 to 60 minutes, when the temperature is 50 to 70DEG C, material is pressed and formed in a forming machine, the heating method is that lateral heating pipes are arranged outside the equipment, and medium with the melting point equal to or above 100 DEG C is pumped in. The preparation method of the blast furnace taphole clay has low labor intensity and high production efficiency.
