It has good hardenability and can be deep-quenched instead of surface-quenched like the anti-saw locks on the market. Due to its special high-quality properties, it is often used to manufacture some high-temperature and high-pressure resistant valves and pressure vessels, such as chromium-molybdenum steel safety valves, chromium-molybdenum steel gate valves, screwdriver bits, bicycles, etc., and the use of chromium-molybdenum steel in rotor shafts can improve its hardness and wear resistance, thereby extending the service life of the equipment; the heat treatment device for alloy steel castings is a device specially designed and used for heat treatment of alloy steel castings, which is usually used to improve the organization and properties of alloy steel castings to meet specific engineering requirements and application needs.

[0003] Existing heat treatment devices for alloy steel castings directly use water resources for cooling, which will lead to resource waste, increased energy consumption, environmental pollution and quality risks, and will increase the cost of heat treatment, resulting in a lack of practicality of the device.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Embodiment 1

[0028] See also Figure 1-5A heat treatment device for chromium-molybdenum high-temperature ferrite steel for mechanical rotors, comprising a main component 1; the main component 1 comprises a box body 11, a heat treatment box 12 is fixedly connected to the top of the box body 11; a placement plate 13, fixedly connected to the inner wall of the heat treatment box 12; a water leakage port 14, both the box body 11 and the heat treatment box 12 are provided with a water leakage port 14; a plate body 15, fixedly connected to the inner wall of the box body 11, and a heating block is arranged inside; a cooling component 2 is arranged on the box body 11, and the cooling component 2 comprises: a vent 21, which is opened on the outer wall of the box body 11, and two are symmetrically opened; a dustproof plate 22, each of the inner walls of the vent 21 is fixedly connected with a dustproof plate 22; a water tank 23, fixedly connected to the inner wall of the box body 11; a filter plate 24, arranged on the water tank 23; a cooling fan 25, symmetrically arranged on the outer wall of the water tank 23, and two groups are arranged; a nozzle 26, arranged inside the heat treatment box 12; a water supply mechanism 27, arranged on the box body 11; the water supply mechanism 27: a water pump 271, fixedly connected to the top of the heat treatment box 12, the water outlet is inserted into the heat treatment box 12, and the nozzle 26 is arranged at the water outlet of the water pump 271; a water pipe 272, inserted into the water tank 23, and the other end is fixedly connected to the water inlet of the water pump 271; a guide shell 6 is fixedly connected to the inside of the water tank 23.

[0029] When ready for use, place the box body 11 at the designated position, then open the revolving door on the heat treatment box 12, place the chromium-molybdenum high-temperature ferrite steel on the placement plate 13, then close the revolving door and heat the object by opening the heating block inside the plate body 15. When the heating is completed, the operator sends the water inside the water tank 23 to the nozzle 26 through the water supply mechanism 27, and sprays the water onto the object through the nozzle 26. Then the water flows through the leakage hole on the placement plate 13 to the leakage port 14, and then the water falls on the filter plate 24 for filtration, and then the filtered water flows back into the water tank 23 for the next use. Then the operator turns on the cooling fans 25 on both sides to dissipate the water flow inside the water tank 23, and discharges the hot air through the vents 21 on one side, and Through the vent 21 on the other side, cold air from the outside is sent into the box body 23 to cool the water.

The operation is simple, which improves the convenience of the device; a guide shell 6 is fixedly connected to the inside of the water tank 23, and the guide shell 6 can guide the water falling into the water tank 23 to prevent the water flow from entering the inside of the cooling fan 25, causing the cooling fan 25 to short-circuit, thereby improving the safety of the device.

[0030] Embodiment 2

[0031] See also Figure 1-5 , based on the first embodiment, a disassembly function is added;

[0032] The water tank 23 is provided with a disassembly assembly 3, and the disassembly assembly 3 includes: a threaded rod 31, which is inserted into the water tank 23 and threadedly connected to the water tank 23; a limit block 32, which is rotatably connected to the bottom end of the threaded rod 31 and slidably connected to the water tank 23; a slide groove 34, which is opened on the inner wall of the water tank 23; a sliding plate 33, which is fixedly connected to the outer wall of the filter plate 24 and slidably connected to the inside of the slide groove 34; a baffle plate 7 is provided on the sliding plate 33, and the baffle plate 7 passes through the sliding plate 33; an electric push rod 4 is fixedly connected to the outer wall of the box body 11, and an L-shaped plate 5 is fixedly connected to the output end of the electric push rod 4, and the L-shaped plate 5 is fixedly connected to the dustproof plate 22.

[0033] When in use, the operator twists the threaded rod 31 to make the threaded rod 31 rotate and rise, thereby driving the limit block 32 to rise at the same time, so that the limit block 32 moves out of the limit groove on the sliding plate 33, and the limit on the sliding plate 33 is cancelled. Then the operator pulls the sliding plate 33 to move in the sliding groove 34, and removes the filter plate 24 through the sliding plate 33, which is convenient for the operator to clean the filter plate 24 and prevents the filter plate 24 from being fixed inside the device and making it inconvenient for the operator to clean or replace it, thereby improving the practicality of the device; a shielding plate 7 is provided on the sliding plate 33, and the sliding plate 33 When moving, the shielding plate 7 is driven to move at the same time, and the gap between the sliding plate 33 and the water tank 23 is covered by the shielding plate 7 to prevent water from falling into the water tank 23 and flowing out through the gap to the inside of the box body 11 to pollute the box body 11, thereby improving the safety of the device; the operator turns on the electric push rod 4, so that the output end of the electric push rod 4 drives one side of the dustproof plate 22 to move outward through the L-shaped plate 5, thereby reducing the obstruction of the gas flow rate by the dustproof net 22 on one side, so that the operator can further improve the heat dissipation efficiency of the water required for cooling the inside of the water tank 23 by turning on the electric push rod 4.
