Description

Technical Field

[0001] The utility model relates to the technical field of chemistry, and particularly relates to a cooling stave assembly for a blast furnace belly. Background Art

[0002] The cooling stave is an important device of the blast furnace body. Its main function is to protect the structure and tightness of the blast furnace shell, so that the blast furnace shell can carry out production under the conditions of high pressure, high temperature and strong corrosion. The complete cooling stave is also the main reliance for forming and stabilizing the inner shape of the blast furnace, and plays a very important role in the smooth, efficient and low-consumption production of the blast furnace.

[0003] When the existing cooling stave is in use, the cooling stave is installed between the brick lining and the furnace shell. The heat transferred from the blast furnace is exchanged with the cooling stave, and the heat is transferred to the environment through the cooling water. This cooling method helps to extend the service life of the refractory materials in the blast furnace and protect the furnace shell from high-temperature damage. Then, the lifting rings are used to fix and support the cooling stave to ensure its stable operation in the blast furnace belly and prevent displacement or damage caused by factors such as high temperature, wear of furnace charge and gas scouring. However, when the lifting rings need to be maintained and repaired after long-term use, the staff need to use special tools to disassemble them. Such operation is complicated and difficult, which is not convenient for the staff to disassemble them, thus reducing the practicability of the equipment. Summary of the Utility Model

Thus, while reducing the workload of the staff, it improves the work efficiency of the staff. The convex block 16 and the brick wall 2 cooperate to support the refractory brick and prevent the slag skin from falling off. At the same time, it changes the scouring path of the coal gas flow and the slag-iron flow, reduces the direct scouring and erosion of the cooling wall 1, and further improves the service life of the cooling wall 1. At the same time, it improves the practicability and effectiveness of the equipment.

[0035] Working principle: First, the cooling wall 1 is installed between the brick lining and the furnace shell through the lifting ring 7. Then, the external equipment is connected to both ends of the cooling pipe 6. Then, the heat transmitted from the blast furnace is exchanged with the cooling wall 1, and the heat is transferred to the environment through the cooling water for cooling. Then, the convex block 16 and the brick wall 2 cooperate to support the refractory brick and prevent the slag skin from falling off. Then, when the lifting ring 7 needs to be disassembled, turn and fix the bolt 9 to rotate it so that the other end thereof disengages from the inside of the fixing bolt groove 13. Then, pull the limiting block 8 to remove it, and then pull the lifting ring 7 to remove the lifting ring 7 and the sliding seat 12 from the cooling wall 1.
