Description

Technical Field

[0002] Coating steel strips is an important process in silicon steel production. Existing steel strips need to be coated with different coating materials on their surfaces. Traditional coating production generally uses two-roller coaters, but it is impossible to coat different coatings on both surfaces of the steel strip at the same time. Instead, the same coating material can only be applied to the upper and lower surfaces of the silicon steel. At the same time, the coating process needs to ensure consistency. Once a failure occurs in the existing coater, the entire system will be shut down for maintenance, seriously reducing the quality of the coating on the steel strips on the line.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0026] In addition, this application may repeat reference numbers and / or reference letters in different examples. This repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed. In addition, this application provides examples of various specific processes and materials, but those of ordinary skill in the art will recognize the application of other processes and / or the use of other materials.

[0027] The present application is described below with reference to specific embodiments and with reference to the accompanying drawings:

[0028] like Figure 1 、 Figure 2 and Figure 3 As shown, this embodiment provides a silicon steel coating system, including two coating devices and a reversing roller group 2; a single coating device includes at least two coating tanks 3, a coating roller group 4 arranged above the coating tank 3 and a liquid storage tank 5 connected to the coating tank 3, the top of the coating tank 3 is open, the liquid storage tank 5 stores coating, and the coating is output to the coating tank 3 through a pipeline. When the coating operation is performed, one surface of the strip steel 1 is located above the coating roller group 4, and the coating roller group 4 applies the coating to the bottom surface of the strip steel 1 at this time through at least two rollers.

[0029] Reference Figure 1The coating tank 3 of one coating device is arranged above the coating tank 3 of another coating device, and the reversing roller group 2 is arranged on the same side of the two coating devices. The strip 1 passes through the coating roller group 4 of one coating device and is wound around the reversing roller group 2. The strip 1 finally passes through the coating roller group 4 of the other coating device. It can be understood that the strip 1 changes its moving direction through the reversing roller group 2 in the coating system, so that the coating operation of the strip 1 before reaching the reversing roller group 2 is the first coating operation, and the coating operation after the strip 1 passes through the reversing roller group 2 is the second coating operation. The two surfaces of the strip 1 are respectively the first side and the second side, and the two coating devices are respectively the first coating device and the second coating device, and the second coating device is located above the first coating device. When the strip 1 is undergoing the first coating operation, the second side of the strip 1 is located above the first side, and multiple coating roller groups 4 of the first coating device coat the first side of the strip 1. After the strip 1 passes through the reversing roller group 2, the first side of the strip 1 is located above the second side. At this time, the second coating operation is performed, and multiple coating roller groups 4 of the second coating device coat the second side of the strip 1.

[0030] Reference Figure 2 During use of the coating system, the first coating device's liquid reservoir 5 and the second coating device's liquid reservoir 5 store different coating materials, thereby completing the coating operation of different coatings on the two surfaces of the steel strip 1. If the first coating device includes multiple liquid reservoirs 5, and each coating tank 3 is connected to a liquid reservoir 5, the coating system of this embodiment can also apply multiple layers of different coatings to the same surface of the steel strip 1.

[0031] A single coating device may have only one coating roller group 4 in operation, and the remaining coating roller groups 4 are on standby. When the coating roller group 4 in operation fails, the remaining coating roller groups 4 can be immediately started to operate, avoiding the phenomenon of uneven coating caused by long-term shutdown. Of course, in this mode, the coating device selects the coating roller group 4 and coating tank 3 near the feed point of the strip 1 for operation.

[0032] When the steel strip 1 needs to have a coating of higher thickness, multiple coating roller sets 4 in a single coating device can be activated to apply multiple layers of coating to the surface of the steel strip 1. That is, the coating system of the embodiment of the present application can adapt to various coating requirements.

[0033] The reversing roller set 2 may include two rollers arranged one above the other, or may include only one roller.

[0034] Considering that some coatings are prone to unevenness after being left standing for a long time, Figure 2A liquid inlet pipe is provided between the coating tank 3 and the liquid storage tank 5, and a circulation tank 7 and a circulation pump 8 are also provided on the liquid inlet pipe. A circulation pipe 13 is also provided at the bottom end of the coating tank 3, and the circulation pipe 13 is connected to the circulation tank 7. During use, after inputting paint into the circulation tank 7, the connection between the circulation tank 7 and the liquid storage tank 5 is disconnected, the coating operation is started, and the circulation pump 8 is energized to operate, so that the paint will circulate between the circulation tank 7 and the coating tank 3, reducing the occurrence of stratification or unevenness and improving the coating quality.

[0035] The coating tank 3 is provided with a liquid inlet and a liquid outlet. The liquid inlet is connected to the liquid inlet pipe, and the liquid outlet is connected to the circulation pipe 13. Furthermore, the liquid inlet and the liquid outlet are spaced apart to ensure that the coating in the coating tank 3 can be circulated. Furthermore, the liquid inlet is provided on the side wall of the coating tank 3, and the liquid outlet is provided at the bottom end of the coating tank 3, away from the liquid inlet, so as to further extend the distance between the liquid inlet and the liquid outlet, ensuring that the coating in the coating tank 3 can enter the circulation tank 7 for circulation.

[0036] In this embodiment, a coating device includes two coating tanks 3, and the two coating tanks 3 are connected to the same liquid storage tank 5. In order to further increase the application scenarios of the coating system of this embodiment, refer to Figure 3 The coating system also includes an auxiliary liquid inlet pipe 12, which connects the circulation tank 7 of one coating device with the coating tank 3 of another coating device. That is, when both surfaces of the strip 1 need to be coated with the same coating, only one liquid storage tank 5 and one circulation tank 7 are needed, that is, the coating can be supplied to all the coating tanks 3 in this embodiment through one circulation tank 7.

[0037] Of course, in the coating operation in which both surfaces of the steel strip 1 are coated with the same coating material, each coating tank 3 is provided with a first drain pipe 9, and the first drain pipes 9 of all coating tanks 3 of each coating device are connected to the same circulation pipe 13; the circulation tank 7 is provided with a first inlet pipe 10 and a second inlet pipe 11, the first inlet pipe 10 is connected to the circulation pipe 13 of one coating device, and the second inlet pipe 11 is connected to the circulation pipe 13 of another coating device. It can be understood that the circulation tank 7 of the first coating device is referred to as the first circulation tank 7, and the circulation tank 7 of the second coating device is referred to as the second circulation tank 7. In the coating operation in which both surfaces of the steel strip 1 are coated with the same coating material, only one circulation pump 8 is turned on, and the coating material in the circulation tank 7 is transported to the coating tanks 3 of different coating devices through the circulation pump 8. At the same time, the coating material in the coating tank 3 is returned to the circulation tank 7 through the first drain pipe 9 and the circulation pipe 13.

[0038] Furthermore, a second drain pipe is provided at the bottom end of the circulation tank 7. When the coating system needs to change the type of coating, the coating in the circulation tank 7, each pipeline and the coating tank 3 can be discharged through the second drain pipe. During cleaning, the cleaning liquid is poured into the coating tank 3, and the cleaning liquid enters the circulation tank 7 along the first drain pipe 9, the circulation pipe 13, the first liquid inlet pipe 10 and / or the second liquid inlet pipe 11. When the liquid level in the coating tank 3 rises, the injection of the cleaning liquid can be stopped, and the circulation pump 8 can be started to achieve the cleaning of the circulation tank 7, each pipeline and the coating tank 3. After cleaning is completed, the cleaning liquid can be discharged again through the second drain pipe.

[0039] Considering that the liquid storage tank 5 is large and not convenient to be installed at a high place, in this embodiment, a delivery pump 6 is provided between the liquid storage tank 5 and the circulation tank 7 to deliver the paint to the circulation tank 7 through the output pump.

[0040] Reference Figure 2 and Figure 3 In this embodiment, each pipeline in the coating system is provided with a valve to ensure that different coating operations can be performed.
