Description

Technical Field

[0001] This utility model relates to the field of dephosphorization equipment, specifically to a high-pressure water dephosphorization device for the surface of steel billets. Background Technology

[0002] Railway elastic clip steel is mainly used in railway tracks. Railway rails are components that support locomotives and guide their direction. The rails are fixed to the sleepers on the ballast bed using elastic fasteners. The fastening components of the elastic fasteners are made of railway elastic clip steel. To meet stringent performance requirements, the surface of railway elastic clip steel must not have a completely decarburized layer during production, and there are strict limits on the total depth of the decarburized layer. Therefore, before the steel billet enters the heating furnace, an anti-decarburization isolating agent is sprayed onto the surface to prevent decarburization from occurring on the surface of the steel billet during the heating process.

[0003] To ensure that the product surface is not completely decarburized, the billet is sprayed with an anti-decarburization isolator before entering the furnace. After the billet exits the heating furnace, it undergoes high-pressure water descaling. The coating material on the surface cannot be completely removed, which causes the residual coating material to be pressed into the steel surface during rolling, leaving pitting defects on the finished product. Therefore, it is necessary to design a high-pressure water descaling device for the billet surface that can reduce coating residue and reduce pitting defects on the surface after rolling. Summary of the Invention

[0004] The purpose of this invention is to provide a high-pressure water descaling device for steel billet surface, which has the advantages of reducing coating residue and reducing surface pitting after rolling.

[0005] The technical solution adopted is as follows:

[0006] A high-pressure water descaling device for steel billet surfaces includes a frame, a water source, a high-pressure water pump, and a standby water pump. The water source is connected to both the high-pressure water pump and the standby water pump. A standby nozzle unit and a spare nozzle unit are spaced apart on the frame. The standby nozzle unit is connected to the high-pressure water pump. The spare nozzle unit includes a mounting frame with multiple spectral analysis sensors corresponding to various surfaces of the steel billet. Multiple spare nozzles are mounted on the mounting frame, each equipped with an electrically controlled valve and connected to a spare water pump. A controller is mounted on the frame and connected to the spectral analysis sensors, the electrically controlled valves, and the spare water pump.

[0007] Preferably, the electrically controlled valve is an electric quick-opening ball valve.

[0008] Preferably, the mounting frame is horizontally provided with multiple telescopic rods, and the spare nozzles are connected to the telescopic rods one by one. The telescopic rods are connected to the controller.

[0009] Preferably, the telescopic rod is a hydraulic telescopic cylinder.

[0010] Compared to existing technologies, the advantages are:

[0011] 1. In this utility model, after the billet is descaled under high pressure by a standby nozzle unit, the spectral analysis sensor on the back side detects each surface of the billet. After detecting residual coating, the controller controls the standby water pump to deliver high-pressure water to the standby nozzle corresponding to the coating and controls the corresponding electronic valve to open for secondary descaling, thereby reducing coating residue and reducing pitting on the surface after rolling.

[0012] 2. This utility model utilizes a telescopic rod to control the movement of the corresponding standby nozzle, enabling the standby nozzle to move synchronously with the steel billet, thereby increasing the high-pressure descaling time of the standby nozzle on the residual coating and improving the descaling effect.

[0018] Example 1: A high-pressure water descaling device for steel billet surface includes a frame 1, a water source 2, a high-pressure water pump 3 and a standby water pump 4. The high-pressure water pump 3 and the standby water pump 4 are of the same specifications. The water source 2 is connected to both the high-pressure water pump 3 and the standby water pump 4, and the water source 2 provides purified water to the high-pressure water pump 3 and the standby water pump 4.

[0019] The frame 1 is provided with a standby nozzle unit 6 and a spare nozzle unit at intervals. The standby nozzle unit 6 is connected to the high-pressure water pump 3. The spare nozzle unit is located downstream of the standby nozzle unit 6. The spare nozzle unit is used to treat the coating remaining on the surface after the standby nozzle unit 6 is descaled by high-pressure water. The spare nozzle unit includes a mounting frame 7, which is located on the outside of the steel billet.

[0020] Mounting frame 7 is equipped with multiple spectral analysis sensors 8 corresponding to various surfaces of the steel billet. By capturing the characteristic absorption peaks of the coating in the near-infrared or short-wave infrared, non-contact detection is achieved. Mounting frame 7 is equipped with multiple spare nozzles 9, each equipped with an electrically controlled valve and connected to a spare water pump 4. The spectral analysis sensors 8 are located between the spare nozzles 9 and the regular nozzle unit 6. Frame 1 is equipped with a controller 10, which is connected to the spectral analysis sensors 8, the electrically controlled valves, and the spare water pump 4. The spectral analysis sensors 8 transmit the detected data to the controller 10. The controller 10 and the spare water pump 4 deliver high-pressure water to the spare nozzles 9 corresponding to the coating and control the corresponding electrically controlled valves to open for secondary descaling.

[0021] Example 2: A high-pressure water descaling device for steel billet surface includes a frame 1, a water source 2, a high-pressure water pump 3 and a standby water pump 4. The high-pressure water pump 3 and the standby water pump 4 are of the same specifications. The water source 2 is connected to both the high-pressure water pump 3 and the standby water pump 4, and the water source 2 provides purified water to the high-pressure water pump 3 and the standby water pump 4.

[0022] The frame 1 is provided with a standby nozzle unit 6 and a spare nozzle unit at intervals. The standby nozzle unit 6 is connected to the high-pressure water pump 3. The spare nozzle unit is located downstream of the standby nozzle unit 6. The spare nozzle unit is used to treat the coating remaining on the surface after the high-pressure water descaling of the standby nozzle unit 6. The spare nozzle unit includes a mounting frame 7, which is located on the outside of the steel billet.

[0023] Mounting frame 7 is equipped with multiple spectral analysis sensors 8 corresponding to various surfaces of the steel billet. By capturing the characteristic absorption peaks of the coating in the near-infrared or short-wave infrared, non-contact detection is achieved. Mounting frame 7 is equipped with multiple spare nozzles 9, each equipped with an electrically controlled valve.

The frame 1 is equipped with a controller 10, which is connected to the spectral analysis sensor 8, the electric control valve, and the spare water pump 4. Multiple telescopic rods 5 are horizontally set on the mounting frame 7. Each spare nozzle 9 is connected to a telescopic rod 5. The telescopic rod 5 is connected to the controller 10. The telescopic rod 5 is a hydraulic telescopic cylinder. The telescopic rod 5 controls the movement of the corresponding spare nozzle 9, so that the spare nozzle 9 moves synchronously with the steel billet, increases the high-pressure descaling time of the spare nozzle 9 on the residual coating, and improves the descaling effect.

[0025] The working principle is as follows:

[0026] The standby nozzle unit 6 performs high-pressure water descaling on the heated steel billet. After the standby nozzle unit 6 performs high-pressure descaling on the steel billet, the spectral analysis sensor 8 on the rear side detects each surface of the steel billet. After detecting the residual coating, the spectral analysis sensor 8 transmits the detection data to the controller 10.

The telescopic rod 5 controls the movement of the corresponding standby nozzle 9, so that the standby nozzle 9 moves synchronously with the steel billet, increasing the high-pressure descaling time of the standby nozzle 9 on the residual coating, and performing secondary descaling.
