Description

Technical Field

[0001] The utility model relates to the technical field of galvanized iron wire processing, in particular to a high-efficiency high-temperature annealing device for hot-dip galvanized iron wire. 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 rate. The purpose is to reduce the hardness and improve the machinability. Annealing is a heat treatment process for materials, including metal materials and non-metallic materials. The annealing process is widely used. In the production process of galvanized iron wire, the galvanized iron wire needs to be subjected to high-temperature annealing treatment.

[0003] When coiled galvanized iron wire is placed in a furnace for annealing without uniform heating inside and outside, the high-temperature annealing efficiency of the hot-dip galvanized iron wire may be affected. This is because the existing annealing furnace heats the galvanized iron wire through in-wall heating, so that during the annealing process, the inside and outside of the galvanized iron wire coil are heated to different degrees, resulting in uneven high-temperature heating and poor annealing effect. Therefore, an efficient high-temperature annealing device for hot-dip galvanized iron wire is proposed to solve the above problem. Utility Model Content

[0004] In response to the shortcomings of the existing technology, the utility model provides a high-efficiency high-temperature annealing device for hot-dip galvanized iron wire, which has the advantages of uniform high-temperature heating during annealing, and solves the problem that the existing annealing furnace heats the galvanized iron wire by heating in the wall, so that during the annealing process, the inside and outside of the galvanized iron wire coil are heated to different degrees, resulting in uneven high-temperature heating and poor annealing effect.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solutions: a high-efficiency high-temperature annealing device for hot-dip galvanized iron wire, comprising a heating assembly arranged inside an annealing furnace body;

[0006] The heating assembly includes an outer heating ring tube and a rotating platform. The outer heating ring tube is arranged inside the annealing furnace body to perform outer annealing heating on the hot-dip galvanized iron wire. The rotating platform is arranged on the inner bottom wall of the annealing furnace body to drive the hot-dip galvanized iron wire coil to be heated at multiple angles. Positioning piles are vertically arranged on the upper surface of the rotating platform to vertically position the hot-dip galvanized iron wire coil. Slots are provided on the four sides of the outer surface of the positioning piles, and internal heating pipes are provided inside the four slots to perform internal annealing heating on the hot-dip galvanized iron wire.

[0007] Furthermore, the outer heating ring tube is spirally distributed on the inner wall of the annealing furnace body to uniformly heat the outer side of the hot-dip galvanized iron wire coil.

[0008] Furthermore, the height of the positioning pile is smaller than the height of the outer heating ring tube, so as to ensure that the galvanized iron wire coil is in the heating cavity.

[0009] Furthermore, the height of the internal heating pipe is equal to the height of the positioning pile.

[0010] Furthermore, the outer heating ring tube and the inner heating tube are both electric heating tubes.

[0011] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0012] This high-efficiency, high-temperature annealing device for hot-dip galvanized iron wire achieves uniform heating of the inside and outside of the hot-dip galvanized iron wire coil, significantly improving the annealing quality and efficiency. The combined use of its rotating platform and internal and external heating tubes not only speeds up the heating speed, but also improves the machinability of the iron wire, thereby enhancing the material's mechanical properties, such as toughness and plasticity. In addition, the uniform heating process reduces material waste, improves material utilization, and ensures product consistency. At the same time, reducing thermal shock also helps to extend the service life of the annealing furnace. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] Example 2: Please refer to Figures 2 to 3On the basis of the first embodiment, the heating assembly 2 in this embodiment includes an outer heating ring tube 21 and a rotating platform 22. The coiled hot-dip galvanized iron wire is placed in the annealing furnace body 1 and is ready for annealing. The hot-dip galvanized iron wire coil is placed on the rotating platform 22. The upper surface of the rotating platform 22 is vertically provided with a positioning pile 23 for vertically positioning the hot-dip galvanized iron wire coil to ensure that the iron wire coil maintains the correct position during the annealing process. The outer heating ring tube 21 is arranged inside the annealing furnace body 1 for performing outer annealing heating on the hot-dip galvanized iron wire. The outer heating ring tube 21 is arranged in the annealing furnace body 1. The inner wall of the main body 1 is used for external annealing heating of the hot-dip galvanized iron wire. The outer heating ring tube 21 is spirally distributed, which can evenly heat the outside of the hot-dip galvanized iron wire coil. The rotating platform 22 is arranged on the inner bottom wall of the annealing furnace body 1 to drive the hot-dip galvanized iron wire coil to be heated at multiple angles. Positioning piles 23 are vertically arranged on the upper surface of the rotating platform 22 for vertical positioning of the hot-dip galvanized iron wire coil. Slots 25 are provided on the four sides of the outer surface of the positioning piles 23, and internal heating pipes 24 are provided inside the four slots 25 for internal annealing heating of the hot-dip galvanized iron wire.

[0020] It should be noted that there are slots 25 on all four sides of the outer surface of the positioning pile 23, and an internal heating tube 24 is provided inside the slot 25 for internal annealing heating of the hot-dip galvanized iron wire. The height of the internal heating tube 24 is equal to the height of the positioning pile 23, ensuring that the inside of the wire coil can also be heated evenly.

[0021] In this embodiment, the outer heating ring tube 21 is spirally distributed on the inner wall of the annealing furnace body 1 to uniformly heat the outside of the hot-dip galvanized iron wire coil. The height of the positioning pile 23 is less than the height of the outer heating ring tube 21 to ensure that the galvanized iron wire coil is in the heating cavity. The height of the internal heating tube 24 is equal to the height of the positioning pile 23. The outer heating ring tube 21 and the internal heating tube 24 are both electric heating tubes. The rotating platform 22 is driven by an external motor to drive the hot-dip galvanized iron wire coil to be heated at multiple angles to ensure that all parts of the iron wire coil can be evenly heated during the annealing process.

The outer heating ring tube 21 and the inner heating tube 24 are both electric heating tubes. The heating temperature can be accurately controlled by controlling the power of the electric heating tube to meet the temperature requirements required for annealing. After heating to a suitable temperature, it is maintained for a certain time so that the inside and outside of the hot-dip galvanized wire coil evenly reach the temperature required for annealing. After completing heating and heat preservation, it is cooled. After cooling is completed, the annealed hot-dip galvanized wire coil is taken out of the annealing furnace body 1 to complete the entire annealing process.
