Preparation method of sand mouth for blast-furnace casting
The invention discloses a preparation method of a long-service-life sand mouth for blast-furnace casting and belongs to the technical field of slag iron separation equipment in the blast-furnace casting process. The preparation method includes the following steps that 1, refractory aggregate is prepared; 2, a binding agent is prepared; 3, the prepared binding agent is added to the refractory aggregate and evenly mixed, and a sand mouth material is obtained; 4, the sand mouth material prepared in step 3 is tamped into a material wall layer by layer, and a cooling water pipe is arranged in the material wall, after each layer is tamped densely, then another layer of sand mouth material is laid, tamping is conducted continuously, and the sand mouth is made after tamping; 5, the tamped sand mouth is sintered and cooled to the room temperature after sintering, and the sand mouth is obtained. By means of the preparation method, the service life reaches about 50 days under the situation that the sand mouth is not repaired, and it is well guaranteed that the blast furnace condition is stable, safe and smooth.
