[0002] A pre-oxidation furnace is a device used to form an oxide film on the surface of steel. Its main function is to protect the steel surface from oxidation. It uses the high-temperature oxidation method. By adding oxygen at high temperature, a stable oxide film is formed on the steel surface. These oxide films can enhance the corrosion resistance and adhesion of the steel, thereby improving the quality of the galvanized layer.

[0003] In the existing pre-oxidation furnace, the pressure control effect is poor, the pressure difference is large within a relatively long period of time, and it cannot ensure a relatively stable pressure state in the pre-oxidation furnace, affecting the quality of subsequent pre-oxidation. Therefore, it is particularly important to design a pre-oxidation furnace with good voltage stabilization effect to solve the above technical problems. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the present utility model will be further described below with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0016] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0017] The utility model provides a pre-oxidation furnace with good voltage stabilization effect, which includes a box body 1. The box body 1 is of a hollow structure. A plurality of support feet 101 are fixedly connected to the bottom of the box body 1. An oxidation treatment area 2 is fixedly connected to the box body 1. An opening 201 is arranged at the position of the box body 1 on the right side of the oxidation treatment area 2. A heating module 3 is arranged below the oxidation treatment area 2. Inlets 4 are installed at both the top and bottom positions of the box body 1. The inlets 4 are connected to ventilation ducts 5. A bracket 401 is fixedly connected to the bottom of the box body 1. A turbo fan 402 is installed on the bracket 401. A power supply 403 is fixedly connected to the box body 1. The turbo fan 402 is connected to the power supply 403 through a cable 404. A flow guide plate 6 is arranged between the turbo fan 402 and the heating module 3. The flow guide plates 6 are staggeredly distributed on the inner wall of the box body 1. A plurality of through holes 405 are evenly distributed on the bracket 401. A sealing door 202 is hinged at the position of the opening 201. The contact position between the sealing door 202 and the box body 1 is sealed, ensuring the relative sealing performance at the position of the sealing door 202 and the opening 201;

[0018] When a pre-oxidation furnace with good voltage stabilization effect is actually in use, the product to be processed is placed into the oxidation treatment area 2 from the position of the opening 201, and then the sealing door 202 is closed. At this time, the power supply module 301 cooperates with the electric wire 302 to supply power to the heating module 3, so as to generate high temperature inside the box body 1. At the same time, the ventilation duct 5 connected to the inlet 4 is connected to supply air into the box body 1. Since the ventilation duct 5 is connected to the upper and lower inlets 4 of the box body 1, an interactive situation is formed between the inside of the box body 1 and the ventilation duct 5. At the same time, the turbine fan 402 installed at the bottom position of the box body 1 works under the cooperation of the power supply 403 and the cable 404 to convey air flow to the position of the heating module 3. Since through holes 405 are evenly distributed on the support 401, the air flow entering from the ventilation duct 5 can accelerate and flow towards the heating position. And a guide plate 6 is arranged above the turbine fan 402. The air flow that enters the oxidation treatment area 2 through the acceleration of the guide plate 6 is in a relatively high-speed state, which is monitored in real time by the pressure monitoring table 7. The staff observes the value on the table in time. Once it is found that the value is high, the driving solenoid valve 702 is opened in time to discharge the gas in the box body 1 and reduce the pressure in the box body 1. Under the control of the staff, the pressure monitoring table 7 and the solenoid valve 702 discharge the pressure in time, ensuring a relatively stable working environment; through the cooperation of the pressure monitoring table 7 and the air pipe 701 with the solenoid valve 702, the high pressure inside the box body 1 is released. The turbine fan 402 arranged in the box body 1 cooperates with the heating module 3 to transmit the high-temperature air flow and convey it to the oxidation treatment area, improving the pre-oxidation treatment efficiency. Compared with the conventional air pressure discharge and pressure control methods, the technical solution adopted by the present utility model can timely and effectively control the pressure inside the box body 1, and the pre-oxidation effect is also greatly improved compared with the conventional treatment methods. The overall structure is compact, which is easy for the staff to install and maintain. It is directly installed inside the box body 1, optimizing the existing working space.

[0019] As Figure 1 shown, a power supply module 301 is arranged on the box body 1. The power supply module 301 is connected to the heating module 3 through an electric wire 302. A pressure monitoring table 7 is installed above the oxidation treatment area 2. An air pipe 701 is installed on the side wall of the box body 1. A solenoid valve 702 is installed on the air pipe 701. The driving of the solenoid valve 702 is controlled by the staff.

[0020] The effect achieved by the entire embodiment 1 is that during use, the pressure monitoring table 7 monitors in real time, and the staff observes the value on the table in time. Once it is found that the value is high, the driving solenoid valve 702 is opened in time to discharge the gas in the box body 1 and reduce the pressure in the box body 1. Under the control of the staff, the pressure monitoring table 7 and the solenoid valve 702 discharge the pressure in time.

[0021] Working principle: Place the product to be processed at the opening position into the oxidation treatment area, and then close the sealing door. At this time, the power supply module cooperates with the wire to supply power to the heating module, generating high temperature inside the box. At the same time, connect the ventilation duct at the inlet position to supply air into the box. Since the ventilation duct is connected to the upper and lower inlets of the box, an interactive situation is formed between the inside of the box and the ventilation duct. At the same time, the turbine fan installed at the bottom of the box works under the cooperation of the power supply and the cable to transport the air flow to the heating module. Since there are uniformly distributed through holes on the bracket, the air flow entering from the ventilation duct can accelerate and flow towards the heating position. And a guide plate is arranged above the turbine fan. The air flow entering the oxidation treatment area through the acceleration of the guide plate is in a relatively high-speed state, which is monitored in real time by the pressure monitoring table. The staff observes the value on the table in time. Once it is found that the value is high, the driving solenoid valve is opened in time to discharge the gas in the box and reduce the pressure in the box. Under the control of the staff, the pressure monitoring table and the solenoid valve discharge the pressure in time to ensure a relatively stable working environment.
