Embodiment 1

[0055] The preparation process of this embodiment can be found in figure 1 , the bulk raw material is heated to 40°C from the storage tank such as the fused corundum by the heating tube 21 outside the fused corundum storage tank 1, see figure 2 , from fused corundum storage tank 1, silicon carbide storage tank 2, clay storage tank 3, coke powder storage tank 4, sericite storage tank 5 and additive storage tank 6, the electric feeder 10 respectively feeds the bulk raw material fused corundum , silicon carbide, clay, coke powder, sericite and additives are added to the weighing funnel device 11, and the weighing funnel device 11 is heated to 70°C by the heating tube 22 outside to ensure that the raw material in the weighing funnel device 11 is 30°C. ℃-40℃, the heating medium in the heating tube in this embodiment is WRY type high temperature heat transfer oil see image 3 , the (reconstitution ratio) of bulk raw materials is:

[0056] Fused corundum 60 Silicon carbide 20 Clay...

Embodiment 2

[0064] The preparation steps of this example are the same as those of Example 1, except that the weight ratio of raw materials and the preparation temperature are different from Example 1. The weight proportion of the bulk raw material of the present embodiment is:

[0065] Fused corundum 40 Silicon carbide 15 Clay 5 Coke powder 5

[0066] Sericite 5 Additives 5.

[0067] The temperature of the bulk raw material in the storage tank is 20°C, heated to 20°C-30°C by the heating tube 22 on the outside of the weighing funnel device 11, dry mixed for 10 minutes, and added a binder with a weight ratio of 15. The mud mill 14 rolled for 40 minutes, and the molding machine 16 was molded at 50°C. The composition (weight ratio) of the blast furnace clay of making is:

[0068] Fused corundum 40 Silicon carbide 15 Clay 5 Coke powder 5

[0069] Sericite 5 Additive 5 Binder 15.

Embodiment 3

[0071] The preparation steps of this embodiment are the same as those of Example 1, and the difference from Example 1 is that the weight ratio of raw materials is different. The composition (weight ratio) of the blast furnace clay made in this embodiment is:

[0072] Fused corundum 50 Silicon carbide 17.5 Clay 7.5 Coke powder 6.5

[0073] Sericite 7.5 Additive 12.5 Binder 20.

Abstract

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.

Description

technical field [0001] The invention relates to a method for preparing blast furnace clay. Background technique [0002] Small blast furnace (1500m 3 Below) the technical parameters of gun mud (including the technical parameters of gun mud itself and the production process parameters) are essentially different from those of large-scale blast furnace mud. . The difference of raw materials, especially the difference of binder affects the technical performance of large blast furnace clay. The existing blast furnace mud preparation method is simple in process, the labor intensity of the operators is high, the ingredients are inaccurate, and the temperature of raw materials and equipment are difficult to control, which has a certain impact on product quality. Unstable; 2. The ingredients are not accurate, and the technical formula requirements cannot be strictly implemented. Contents of the invention [0003] In order to overcome the above-mentioned shortcomings of the exis...
