Description

Technical Field

[0001] This invention relates to the field of heat treatment trolley technology, specifically to the frame of a heat treatment trolley. Background Technology

[0002] The factory has many large heat treatment trolley-type industrial kilns. Traditionally, the trolley surfaces are constructed using refractory materials, typically ordinary clay bricks. Later improvements used refractory castables, but neither method solved the problem of trolley frame collapse and cracking. This is especially true in heavy industrial plants where forgings and castings weighing hundreds of tons are used. Even the highest-grade refractory materials used for the platform can be crushed by the weight of these forgings and castings. As a result, the frames of large heat treatment furnaces in heavy industrial plants are generally in a dilapidated state. In view of this situation, through technical personnel investigating the current condition of heat treatment industrial furnace trolleys in several heavy industrial plants and consulting with on-site management personnel, a heat-resistant steel component was designed that is high-temperature resistant, oxidation resistant, does not deform under relative operating temperatures, and is durable, to replace the currently used refractory materials, fundamentally solving this problem. Summary of the Invention

[0003] The purpose of this invention is to overcome the above-mentioned technical defects and provide a heat treatment trolley frame. The frame is made of a mixture of various precious metals and has the advantages of high temperature resistance, oxidation resistance, and non-deformation at high temperatures. Large heat treatment trolleys made using the frame in this application have neat, beautiful, durable, and environmentally friendly frames.

[0004] To solve the above-mentioned technical problems, the technical solution provided by the present invention is as follows: a heat treatment trolley frame, including a trolley body and a table frame, wherein the table frame is made of heat-resistant steel casting, and the table frame is fixedly connected to the top perimeter of the trolley body. The table frame includes an inner insert plate and an outer frame plate, wherein the inner insert plate and the outer frame plate are integrally formed by one-time smelting and casting, the outer side of the upper end of the inner insert plate is connected to the inner side of the lower end of the outer frame plate, the bottom surface of the outer frame plate overlaps the edge of the top surface of the trolley body, and the inner insert plate is inserted into the interior of the top surface of the trolley body and integrally cast with the table frame.

[0005] Furthermore, the heat-resistant steel casting used for the tabletop frame is made of chromium-titanium-nickel alloy casting.

[0006] Furthermore, the top surface of the inner insert plate is provided with an inwardly inclined slope surface at 45°.

[0007] Furthermore, the top of the outer frame plate is provided with a horizontal surface, and the top of the outer frame plate is provided with an outwardly inclined slope surface at 45° outside the horizontal surface.

[0008] Furthermore, the inner insert plate has a thickness of 20mm, the height of the part overlapping the lower end of the outer frame plate excluding the inner slope surface is 30mm, and the height of the lower end of the inner insert plate extending out is 50mm.

[0009] Furthermore, the outer frame plate has a thickness of 30mm, a height of 150mm, and a horizontal thickness of 10mm.

[0010] The advantages of this invention compared to existing technologies are as follows: This invention uses heat-resistant steel castings as the frame of the heat treatment furnace trolley to replace the edges of refractory bricks and refractory castables, which can thoroughly change the unsightly phenomena of dilapidated, environmentally unfriendly, and energy-wasting heat treatment furnaces that are common in many large manufacturers. The frame is made of a mixture of various precious metals, which has the advantages of high temperature resistance, oxidation resistance, and non-deformation at high temperatures, allowing the equipment to remain neat, clean, beautiful, and durable for a longer period of time.

[0015] The present invention will now be described in further detail with reference to the accompanying drawings.

[0016] like Figure 1-3 As shown, the heat treatment trolley frame includes a trolley body 1 and a table frame 2. The table frame 2 is made of heat-resistant steel casting. The table frame 2 is fixedly connected to the top perimeter of the trolley body 1. The table frame 2 includes an inner insert plate 3 and an outer frame plate 4. The inner insert plate 3 and the outer frame plate 4 are integrally formed by one-time smelting and casting. The outer side of the upper end of the inner insert plate 3 is connected to the inner side of the lower end of the outer frame plate 4. The bottom surface of the outer frame plate 4 overlaps the edge of the top surface of the trolley body 1. The inner insert plate 3 is inserted into the inside of the top surface of the trolley body 1 and integrally cast with the table frame.

[0017] In this embodiment, the heat-resistant steel casting used for the tabletop frame 2 is made of chromium-titanium-nickel alloy casting.

[0018] In this embodiment, the top surface of the inner insert plate 3 is provided with an inwardly inclined slope 5 at 45°.

[0019] In this embodiment, the top of the outer frame plate 4 is provided with a horizontal surface 6, and the top of the outer frame plate 4 is provided with an outwardly inclined slope surface 7 at 45° outside the horizontal surface 6.

[0020] In this embodiment, the inner insert plate 3 has a thickness of 20mm, and the height of the part overlapping the lower end of the outer frame plate 4, excluding the inner slope surface 5, is 30mm. The height of the lower end of the inner insert plate 3 extending out is 50mm.

[0021] In this embodiment, the outer frame plate 4 has a thickness of 30mm and a height of 150mm, and the horizontal surface 6 has a thickness of 10mm.

[0022] In its specific implementation, this invention uses a heat-resistant steel casting made from a chromium, titanium, and nickel alloy. This frame is not only heat-resistant and oxidation-resistant, but also does not deform under certain operating temperatures, ensuring durability. It replaces the refractory material at the edges of current heat treatment trolleys. During installation, the outer side of the outer frame plate is flush with and tightly connected to the outer side of the trolley, both on the same plane. The inner insert plate is inserted downwards into the trolley surface and integrally cast with the refractory castable. This invention addresses the unsightly state of many large manufacturers' heat treatment furnaces, which are dilapidated, environmentally unfriendly, and energy-wasting. The frame, made from a mixture of various precious metals, has the advantages of high-temperature resistance, oxidation resistance, and resistance to deformation at high temperatures. This allows the equipment to remain neat, clean, and aesthetically pleasing for extended periods, ensuring durability. Even when the platform withstands hundreds of tons of forged castings, the frame will not be damaged.

[0023] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
