Replacing device of burner of annealing furnace

Abstract

The invention belongs to the technical field of metallurgy thermal treatment and provides a replacing device of a burner of an annealing furnace. The replacing device of the burner of the annealing furnace comprises a conveying unit, a guide unit and a power unit. The guide unit is arranged at one end of the conveying unit. The guide unit is provided with an arrangement block. The arrangement block is used for arrangement of the burner of the annealing furnace. One end of the power unit is arranged in the guide unit and used for adjusting the height of the guide unit. Compared with the prior art, the replacing device of the burner of the annealing furnace has the advantages of being simple in structure, saving labor, avoiding damage to a burner refractory material, prolonging the service life of the burner and achieving the effects of lowering the labor intensity and improving the operation quality. The replacing device of the burner of the annealing furnace is simple in operation method, and compared with a traditional operation method, the operation method of the replacing device of the burner of the annealing furnace has the advantages of being high in labor efficiency, low in potential safety hazard and controllable in operation process.

Description

technical field [0001] The invention belongs to the technical field of metallurgical heat treatment, and in particular relates to a burner replacement device for an annealing furnace. Background technique [0002] The annealing furnace is an important equipment in the continuous hot-dip galvanizing production line of the strip steel. The burner is used as the heating equipment of the annealing furnace. The high-temperature annealing of the burner can eliminate the rolling stress of the strip steel, improve the mechanical properties, and be ready for hot-dip galvanizing. Therefore, the heating condition of the burner directly affects the surface quality of the product. The specific requirements for the installation of the burner are uniform heating, good insulation and refractory materials, and no air leakage on the contact surface with the furnace wall. [0003] At present, the replacement of burners in annealing furnaces in domestic steel mills is mostly done manually by ha...

AI Technical Summary

Problems solved by technology

[0003] At present, the replacement of burners in annealing furnaces in domestic steel mills is mostly done manually by hanging up and down the chain. However, due to the unstable shaking of the burners during the hoisting process, this method is likely to cause the refractory materials and fiber seals of the burners to fall off and be damaged. The verticality of the installation of the furnace wall cannot be guaranteed. After the bolts are fastened, they are forced into the fiber seal and the deformation of the refractory material is easy to cause air leakage. At the same time, the temperature of the annealing furnace is high, and the original manual replacement operation is easy to cause burns, and the weight of a single burner About 350 catties, manpower combined with lifting and replacement caused great manpower consumption
