TECHNICAL FIELD

[0001] The present application relates to the technical field of narrow strip steel production equipment, in particular to a fast cooling prevention device and method for a narrow strip steel flat chain. BACKGROUND

[0002] In the production of narrow strip steel, the finished steel strip is usually coiled vertically, and the steel strip is uniformly placed in a snake shape on the flat chain under the joint action of the snake vibration and the flat chain guard plate, and then naturally cooled. Although this cooling method is simple and reliable, the overlap between the guard plate and the steel strip will continue to cool down quickly, resulting in uneven cooling of the finished steel strip, which poses a serious risk to product quality. Therefore, we need a fast cooling prevention device and method for a narrow strip steel flat chain to reduce the quality risk of uneven cooling of the finished steel strip. SUMMARY

[0003] The present application overcomes the shortcomings of the prior art and provides a fast cooling prevention device and method for a narrow strip steel flat chain. The running channel width of the narrow strip steel on the flat chain is adjusted in real time to achieve the purpose of limiting and restraining the narrow strip steel. After the narrow strip steel is fully distributed on the flat chain, the guard plate moves backward to prevent the steel strip from being in contact with the guard plate overlap point for a long time and quickly cooled, thereby reducing the quality risk of uneven cooling of the finished steel strip.

[0004] In a first aspect, the present application provides a fast cooling prevention device for a narrow strip steel flat chain, comprising two long guard plates arranged above the flat chain, the arrangement direction of the long guard plates being consistent with the conveying direction of the flat chain, each long guard plate being connected to an extension device to drive the long guard plate to move towards or away from the center position of the flat chain, and a detection pyrometer arranged at the inlet of the flat chain to detect the conveyed narrow strip steel.

[0005] Further, the extension device comprises a pneumatic cylinder.

[0006] Further, an electric control unit and an electromagnetic valve electrically connected thereto are further included, and the electromagnetic valve is electrically connected to the two pneumatic cylinders.

[0007] Further, the detection pyrometer is electrically connected to the electric control unit.

[0008] In a second aspect, the present application further provides a fast cooling prevention method for a narrow strip steel flat chain, using the fast cooling prevention device of any one of the first aspect, further comprising the following steps: Two long guards are arranged on both sides of the width direction above the flat chain, when the high-temperature narrow strip steel at the entrance of the flat chain is detected by using the high-temperature detector, the electric control unit sends a signal to the electromagnetic valve to control the opposite movement of the pneumatic cylinder, the two long guards narrow the running channel of the narrow strip steel on the flat chain, and the steel belt is constrained, when the narrow strip steel is fully laid on the flat chain, the electric control unit sends a signal to the electromagnetic valve to control the back movement of the pneumatic cylinder, so that the two long guards are away from the narrow strip steel on the flat chain and translate to both sides respectively.

[0009] The beneficial effects of the present application are: The present application is applied to the cooling process in the production of narrow strip steel, the width of the running channel of the narrow strip steel on the flat chain is adjusted in real time by arranging two long guards with adjustable positions, the purpose of limiting and constraining the narrow strip steel is achieved, and after the narrow strip steel is fully laid on the flat chain, the guards move backward, so that the steel belt and the overlap point of the guards are prevented from being in contact for a long time and rapidly cooled, and the quality risk of uneven cooling of the finished steel belt is reduced.

[0012] It can be understood that the aforementioned fast cooling prevention device of the present application is a fast cooling prevention automatic displacement guard for the narrow strip steel flat chain applied in the field of narrow strip steel production, which achieves the purpose of reducing the quality risk of uneven cooling of the finished steel belt. The use process is as follows: S1. Two horizontally movable long guards 101 are installed on both sides of the flat chain 100, and the guards are displaced by the telescopic extension of the two pneumatic cylinders 102; S2. A high-temperature sensor 103 is installed on the inlet side of the flat chain 100. When there is a steel signal, it is transmitted to the electronic control unit 104.
