Description

Technical Field

[0002] With the continuous improvement of the smelting intensity of iron-making blast furnaces, the refractory materials inside the blast furnaces and their supporting hot air systems will be greatly eroded during the high-intensity production and operation process. The longevity of the blast furnaces and their hot air systems has become increasingly prominent. Grouting operation is one of the important means of maintaining the longevity of blast furnaces and their hot air systems.

[0003] Due to the different structures of different parts of the blast furnace and its hot air system and the different refractory materials used, the requirements for the use of grouting materials are also very different. At the same time, different grouting materials are used to deal with different problems. As for the grouting material, which needs to be stirred and mixed with the relevant solvents, due to the different particles of the solid powder, the grouting equipment is often blocked, resulting in the construction being unable to proceed as planned, seriously affecting the progress and efficiency of the construction, and giving the partners a very poor sense of identity. At the same time, the original mixer can only be used for the mixing and grouting of granular materials. Other grouting materials cannot be reused, and new equipment needs to be added to hold other grouting materials, which increases costs.

[0004] Based on this, a slurry mixing and filling integrated equipment for blast furnace is proposed. Utility Model Content
