Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of heat treatment equipment, specifically to a high-strength stainless steel gradient heat treatment device. Background Technology
[0002] Heat treatment is a crucial method for improving the performance of high-strength stainless steel. Conventional heat treatment methods, such as overall heating and holding followed by cooling, can improve material properties to some extent, but they are difficult to meet the stringent requirements for the gradient distribution of material properties under complex working conditions. Some advanced heat treatment technologies, such as induction heating, can achieve rapid localized heating, but they have limitations in terms of precise temperature field control and achieving continuous gradient changes.
[0003] Traditional heat treatment equipment often suffers from uneven heating when processing large, complex-shaped, high-strength stainless steel workpieces. This results in significant performance differences between different parts of the workpiece, failing to fully realize the material's potential and potentially causing safety hazards during use due to inconsistent performance. Utility Model Content
[0004] Technical problems to be solved In view of the above-mentioned shortcomings of the existing technology, the present invention provides a high-strength stainless steel gradient heat treatment device, which can effectively solve the problems in the existing technology.
[0005] Technical solution To achieve the above objectives, this utility model provides the following technical solution: This utility model provides a high-strength stainless steel gradient heat treatment device, including an electric furnace. The electric furnace has a gradient layering component inside, which includes a mounting frame fixed to the inside of the electric furnace and a heating component fixed to the inner wall of the electric furnace. The gradient layering component includes a top frame, a middle frame, and a bottom frame. The top frame is fixedly connected to the inner wall of the electric furnace by a mounting rod. A limiting frame is fixed between the heating components on both sides. The bottom frame is located at the bottom end of the limiting frame. The top and bottom ends of the electric furnace are provided with slots, and air ducts are inserted and fixed in the slots. Auxiliary heating components are fixed at both ends of the inner side of the limiting frame.
[0006] Furthermore, the heating component is an electric heating element structure, and the heating component is fixed to the inner wall of the electric furnace by a mounting plate.
[0007] Furthermore, the inner wall of the electric furnace is stacked with magnesia-carbon bricks coated with a high-temperature resistant coating, and the top frame, middle frame and bottom frame are all arc-shaped structures.
[0008] Furthermore, the limiting frame is spindle-shaped with larger sides and a smaller middle, and the auxiliary heating component is fixed to the inner wall of the limiting frame.
[0009] Furthermore, the bottom frame is fixed to the inner top of the electric furnace by a mounting frame.
[0010] Furthermore, the electric furnace has three sets of outlets on the other side, and the outer top cover of the electric furnace is a furnace cover.
[0011] Beneficial effects The technical solution provided by this utility model has the following advantages compared with the known public technology: This invention utilizes a gradient layered structure with a limiting frame and auxiliary heating components within the electric furnace. High-temperature heating is achieved through the heating components on both sides of the furnace, while the magnesia-carbon brick structure with a high-temperature resistant coating provides heat insulation. The three-layer structure exhibits a significant temperature difference. On the top and bottom frames, the user can place stainless steel components on top for heat treatment, setting the temperature of the heating components and performing the heat treatment operation before removing them from one side of the furnace outlet. The limiting frame structure in the middle receives continuous heating from the auxiliary heating components on both sides, and its spindle-shaped design concentrates heat in the center, amplifying the heat's effect. When structural components are placed within this structure, unlike the top and bottom layers, it allows for heat treatment at higher set temperatures. Furthermore, the gradient layered structure is entirely arc-shaped, which can be used to shield structures that do not require heat treatment from deformation caused by high temperatures.

[0017] Example: A high-strength stainless steel gradient heat treatment apparatus, as shown in the attached document.

The gradient layering component 4 includes a mounting frame 44 fixed to the inner side of the electric furnace 1 and a heating component 45 fixed to the inner wall of the electric furnace 1. The gradient layering component 4 includes a top frame 41, a middle frame 42 and a bottom frame 43. The top frame 41 is fixedly connected to the inner wall of the electric furnace 1 by a mounting rod. A limiting frame 47 is fixed between the two heating components 45.

The heating component 45 is an electric heating element structure, and the heating component 45 is fixed to the inner wall of the electric furnace 1 by the mounting plate 48. The inner wall of the electric furnace 1 is stacked with magnesia-carbon bricks coated with a high-temperature resistant coating, and the top frame 41, middle frame 42 and bottom frame 43 are all arc-shaped structures. Through the set gradient layering component 4, and the addition of the limiting frame 47 and auxiliary heating component 46 in the electric furnace 1, high-temperature heating can be carried out in the electric furnace 1 through the heating components 45 on both sides inside, and heat insulation and heat preservation can be carried out through the magnesia-carbon brick structure with a high-temperature resistant coating. There is a significant temperature difference in the three-layer structure. On the top and bottom sides, i.e. the top frame 41 and bottom frame 43 structure, the user can place stainless steel parts on the top for heat treatment, set the temperature of the heating component 45 in the electric furnace 1, carry out the heat treatment operation, and remove it from the outlet of the electric furnace 1 on one side.

When the structural component is placed in it, it is different from the upper and lower layers, which can meet the heat treatment effect at a higher set temperature. Moreover, the gradient layered structure is all arc-shaped, which can be used to shield the structure that does not need to be heat treated from deformation caused by high temperature.
