Description

Technical Field

[0001] This utility model relates to the field of roller grating cooling technology, specifically an automatic cooling device for roller grating. Background Technology

[0002] In the rolling of heavy plates, in order to meet the process performance of the steel plates, it is necessary to control the rolling temperature of the second stage. The steel plates need to wait for the temperature to drop to the required process temperature in the roller table area of ​​the mill input and output. This results in a high temperature in the waiting area of ​​the steel plates, and the lack of grating plates for cooling on the conveying rollers causes the grating plates to arch after a long waiting period, making it impossible for the steel plates to pass through the roller table normally. Utility Model Content

[0003] To address the problems existing in the prior art, this utility model provides an automatic cooling device for roller grating plates used in rolling mills, comprising a water pump, cooling water pipes, nozzles, a temperature monitoring device, and a control unit.

[0004] Cooling water pipes connect the nozzle inlet and the water pump outlet. The water pump is connected to an external water source. A temperature monitoring device monitors the temperature of the grating in the mill roll table area. The temperature monitoring device and the water pump are connected to the control unit, which controls the water pump. The control unit is also connected to the mill control system to read whether steel plates are present in the mill roll table area. When the grating needs cooling, the control unit activates the water pump, which cools the grating through the nozzles.

[0005] Furthermore, the water pump also includes a pneumatic control valve, which is located at the water pump outlet; the pneumatic control valve is connected to the control unit and is controlled by the control unit.

[0006] Furthermore, the temperature monitoring device is an infrared monitoring device.

[0007] Furthermore, the temperature monitoring device monitors the temperature of the grating plate between two adjacent rolls on the rolling mill.

[0008] Furthermore, it also includes a mounting rod, with the temperature monitoring device installed at the top of the mounting rod for easy monitoring of the grid plate temperature.

[0009] Furthermore, the nozzle is installed on the isolation wall in the rolling mill roll passage area.

[0010] Furthermore, a nozzle is installed on the isolation wall between two adjacent rollers on the rolling mill to ensure uniform cooling.

[0011] Furthermore, when the temperature monitoring device detects that the temperature of the grating plate is higher than the first threshold, and the control unit reads that there is no steel plate in the rolling mill roll table area, the control unit starts the water pump to prevent cooling water from splashing onto the steel plate.

[0012] Furthermore, when the temperature monitoring device detects that the temperature of the grating plate is higher than the first threshold, and the control unit reads that there is no steel plate in the mill roll table area, the control unit also sends a signal to the mill control system to rotate the rollers, so as to prevent the cooling water from splashing onto the rollers and causing local cooling that could lead to roller deformation.

[0013] Furthermore, when the temperature monitoring device detects that the temperature of the grating plate is lower than the second threshold, or when the control unit reads that there is a steel plate in the mill roll table area, the control unit shuts off the water pump.

[0014] This invention can effectively cool overheated grating plates without interfering with the normal steel plate production process. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] See Figure 1-3 This embodiment is an automatic cooling device for roller grating plates, used in rolling mill 1. It includes a water pump 2, a cooling water pipe 3, a nozzle 4, a temperature monitoring device 5, and a control unit. The water pump 2 also includes a pneumatic control valve 10, which is installed at the outlet of the water pump 2.

[0022] The temperature monitoring device 5 is an infrared monitoring device, and its monitoring range is the grating plate 6 between two adjacent rollers 7 on the rolling mill 1. It also includes a mounting rod 8, on the top of which the temperature monitoring device 5 is mounted to facilitate monitoring the temperature of the grating plate 6.

[0023] The nozzle 4 is installed on the isolation wall 9 in the roller table area of ​​the rolling mill 1. A nozzle 4 is provided on the isolation wall 9 between two adjacent roller tables of the rolling mill 1 to make the cooling process uniform.

[0024] Cooling water pipe 3 connects the inlet of nozzle 4 and the outlet of water pump 2. Water pump 2 is connected to an external water source. Temperature monitoring device 5 is used to monitor the temperature of grating plate 6 in the roller table area of ​​rolling mill 1. Temperature monitoring device 5 and water pump 2 are connected to control unit, and water pump 2 is controlled by control unit. Control unit is also connected to rolling mill 1 control system to read whether steel plate is present in the roller table area of ​​rolling mill 1.

[0025] When the temperature monitoring device 5 detects that the temperature of the grating plate 6 is higher than the first threshold, and the control unit reads that there is no steel plate in the roller table area of ​​the rolling mill 1, the control unit starts the water pump 2 to prevent cooling water from splashing onto the steel plate. At the same time, the control unit also sends a signal to the rolling mill 1 control system to rotate the roller 7 to prevent localized cooling of the roller 7 after the cooling water splashes onto it, which could cause deformation of the roller 7. For the water pump 2 equipped with a pneumatic control valve 10, it is also necessary to control the opening and closing of the pneumatic control valve 10.

[0026] When the temperature monitoring device 5 detects that the temperature of the grating plate 6 is lower than the second threshold, or when the control unit reads that there is a steel plate in the roller table area of ​​the rolling mill 1, the control unit shuts off the water pump 2. The first threshold and the second threshold can be set according to actual needs. In this embodiment, the first threshold is set to 100°C and the second threshold is set to 50°C.
