Description

Technical Field

[0001] The invention relates to the technical field of wire annealing, and in particular to a high-efficiency and energy-saving pit-type special annealing furnace for wires. Background Art

[0002] Annealing is a metal heat treatment process, which means slowly heating the metal to a certain temperature, keeping it for a sufficient time, and then cooling it at an appropriate speed. The purpose is to reduce hardness, improve machinability; eliminate residual stress, stabilize size, reduce deformation and crack tendency; refine grains, adjust structure, and eliminate structural defects. When annealing low expansion alloy wire, a pit annealing furnace is required. When using it, the coiled wire is directly placed in the annealing furnace through a hanger to heat it, and then taken out of the furnace for annealing.

[0003] Before placing the coiled wire into the furnace, multiple bundles of wire need to be stacked on a pallet with a column fixed in the middle of the pallet. After the wires are stacked on the pallet, they are lifted by a sling and placed into the furnace. Since the wires are directly stacked on the pallet, there is a gap between the inside of the wires and the column. If the wires shift during the movement, it will affect the subsequent placement of the wires. Therefore, when lifting and placing the wires, it is necessary to ensure that the wires are coaxial with the pallet. However, when annealing coiled wires of different diameters, pallets of different diameters need to be replaced. The required pallets are of large specifications and quantity, which is inconvenient to use.

[0004] Secondly, multiple coils of wire are stacked on a pallet, and the coils of wire are close to each other, so that the heating efficiency of the close surface is not as good as that of the side surfaces. After the wire reaches a certain annealing temperature, the wire becomes soft as a whole. The wire at the bottom is subjected to the pressure of the wire above, which will cause indentation or deformation, thus seriously affecting the quality of the wire.

[0005] The existing annealing furnace relies on the heater on its side wall to heat the air in the furnace. The outer side of the wire, which is closer to the furnace wall, is heated first, while the inner side of the wire is heated slowly, resulting in uneven heating of the entire wire.

[0006] Therefore, the present invention provides a high-efficiency and energy-saving pit-type wire rod special annealing furnace to solve the above problems. Summary of the invention
