[0002] Heat treatment refers to a metal heating process in which the workpiece is heated, kept warm and cooled in the solid state to change the chemical composition and structure of the material surface or inside to obtain the desired properties.

[0003] With the rapid development of my country's manufacturing industry, market competition is becoming increasingly fierce. For manufacturers, heat treatment is one of the important processes that determine the performance of mechanical workpieces and the energy consumption of the production process. At present, most Changji Ajiang alloys are directly loaded into the heat treatment furnace during the heat treatment process of the alloy. See the Chinese utility model patent with the authorization announcement number CN208995543U, which discloses a structure in which the heated workpiece is lifted by the lifting arm and moved to the top of the heating furnace, and then placed in the heating furnace from top to bottom. In this way, the heated workpiece is simply transferred by radiation heat in the heat treatment furnace, which leads to uneven heating of the inner ring of the steel coil and overheating of the outer ring, thereby wasting energy and failing to control the quality of the steel coil. Therefore, this heat treatment method needs to be improved.

[0004] Therefore, based on the above technical problems, technicians in this field urgently need to develop a tooling rack for a heat treatment furnace. Utility Model Content

[0013] a bottom disc located at the bottom; and

[0014] The M-shaped steel structure support member fixed to the bottom disc;

[0015] The end of the M-shaped steel structure support extends to the edge of the bottom disc;

[0016] The cross-sectional dimension of the bottom disc is greater than the cross-sectional dimension of the limiting assembly.

[0017] Furthermore, the limiting component includes:

[0018] Thin-walled tube;

[0036] This embodiment discloses a heat treatment furnace tooling rack, which includes:

[0037] Support component 1 and limit component;

[0038] The limiting assembly is arranged on the supporting assembly 1, and the limiting assembly forms a receiving space for receiving the steel coil;

[0039] When the steel coil is placed in the accommodation space, the steel coil is supported by the support assembly 1;

[0040] The support assembly 1 has a M-shaped steel support member 102 , and the steel coil is formed into a multi-point support structure through the M-shaped steel support member 102 , and the steel coil and the support assembly 1 form multiple ventilation areas 103 through the M-shaped steel support member 102 .

[0041] Specifically, the present embodiment discloses a tooling rack for supporting steel coil workpieces, the tooling rack comprising a support assembly 1 and a limit assembly; wherein the support assembly 1 supports the steel coil workpiece using a M-shaped steel structure support 102, and the limit assembly reserves space for accommodating the steel coil workpiece, and the internal space size meets the storage requirements of the steel coil workpiece, and due to the setting of the M-shaped steel structure support 102, not only can a multi-point support structure be formed for the steel coil workpiece, but also a plurality of ventilation areas 103 can be provided for the steel coil workpiece through the M-shaped steel structure support 102, so as to realize radiation and heat convection and increase the heat transfer effect.

[0042] Preferably, the support assembly 1 of this embodiment includes:

[0043] A bottom disc 101 located at the bottom; and

[0044] A M-shaped steel support member 102 fixed to the bottom disc 101;

[0046] The cross-sectional dimension of the bottom disc 101 is larger than the cross-sectional dimension of the limiting assembly.

[0047] First, this embodiment further defines the structure of the support assembly 1, which includes a bottom disc 101 and a cross-shaped steel support 102; the bottom disc 101 can increase the contact area and reduce the pressure of the steel coil on the heat treatment furnace. The cross-shaped steel support 102 forms a multi-point support structure for the steel coil workpiece through six supporting parts.

[0048] The limiting assembly of this embodiment includes:

[0049] Thin-walled tube 2;

[0050] The thin-walled tube 2 and the bottom disc 101 are coaxially fixed on the M-shaped steel structure support 101;

[0051] The M-shaped steel structure support 101 has six extension arms, and the M-shaped steel structure support 101 is connected to the thin-walled tube 2 through the extension arms, and the space between adjacent extension arms is a ventilation area 103 .

[0052] The thickness of the thin-walled tube 2 in this embodiment is 2 mm.

[0053] This embodiment further defines the structure of the limit assembly, which is a thin-walled tube 2 with a wall thickness of 2 mm. The thickness cannot be too thin, which is easy to deform; and cannot be too thick, which is easy to affect convection heat transfer. The thin-walled tube 2 of this embodiment is fixed on the M-shaped steel support 102, supported by six extension arms of the M-shaped steel support 102, and formed into six ventilation areas 103 at the bottom.

[0054] In order to allow the tooling to be used in a high temperature environment, to play a certain protective role and to extend the service life, a refractory material layer is laid on the surface of the bottom disc 101 and the M-shaped steel support 102 of the present embodiment.

This alloy can withstand high temperatures of 1280°C, and has high thermal strength, good high-temperature creep resistance, good thermal fatigue performance, and a long service life. It can also withstand embrittlement and other factors caused by different heat treatment atmospheres (such as oxidation, carburizing, nitriding, etc.), and has obvious advantages over stainless steel components.
