Description

Technical Field

[0001] This invention belongs to the field of direct rolling technology in steel rolling mills, and particularly relates to a direct rolling mill exit roller table pushing device. Background Technology

[0002] To reduce the consumption of heating furnace gas, water, electricity, and other media, and to decrease the oxidation loss of steel billets, the corresponding production lines and equipment were upgraded and transformed. The main upgrade adopted was a hot-feed direct rolling process to achieve heat-free rolling of rebar, thereby reducing energy consumption and improving product market competitiveness. A four-channel process layout was adopted, namely, No. 1 continuous casting machine - south / north rolling line, and No. 2 continuous casting machine - south / north rolling line, truly realizing the integration of continuous casting and steel rolling production organization. The use of heat-free rolling technology lowered the initial rolling temperature, creating favorable conditions for the entire production line to adopt thermomechanical rolling and reduce alloy composition.

[0003] Initially, the No. 1 continuous casting machine-South / North rolling line and the No. 2 continuous casting machine-South / North rolling line mode used manual reversing. During production, the "one machine, two lines" mode was often required for various reasons. After the modification, at the exit roller table of the straight rolling mill, the steel billet was not straight due to the curvature of the roller table groove, and often could not enter the rolling mill, which delayed production. Moreover, if the steel billet being transported in the curved roller table groove was long, it was easy to come into contact with the edge of the roller table groove during the downward transport, resulting in abnormal transport. To solve the above problems, a push-alignment device has now been installed.

[0004] It should be noted that the above content falls within the inventor's technical knowledge and does not necessarily constitute prior art. Summary of the Invention

[0005] To address the aforementioned problems, the present invention aims to provide a direct rolling mill exit roller table pushing and straightening device. During the billet conveying process, a distance sensor detects the distance between the billet and the outer edge of the direct rolling mill exit roller table track. When the billet is detected to be close to the outer edge of the direct rolling mill exit roller table track, the corresponding pushing and straightening component is activated to push and straighten the billet so that it can continue to be conveyed or smoothly enter the rolling mill.

[0006] To achieve the above objectives, the present invention proposes a straightening device for a direct rolling mill exit roller conveyor, which is used to straighten the steel billet conveyed by the direct rolling mill exit roller conveyor. The direct rolling mill exit roller conveyor is arc-shaped, and the straightening device includes several straightening components, which are uniformly fixed inside the track of the direct rolling mill exit roller conveyor.

[0007] The pushing and straightening assembly includes a first fixed seat fixed inside the direct rolling mill exit roller track, a position adjusting assembly fixed above the first fixed seat, a first fixed block fixed on the position adjusting assembly, a limiting assembly for restricting the steel billet installed on the first fixed block, and a pushing assembly for pushing the steel billet to move fixed on the limiting assembly.

[0008] Furthermore, several detection components for detecting the position of steel billets are fixed on the outer side of the track of the direct rolling mill exit roller table.

[0009] Furthermore, the adjustment assembly includes a first electric telescopic rod fixed above a first fixed base, a drive box fixed above the output shaft of the first electric telescopic rod, a first motor fixed inside the drive box, a horizontal second electric telescopic rod vertically fixed on the output shaft of the first motor, and a first fixed block fixed on the output shaft of the second electric telescopic rod.

[0010] Furthermore, the limiting component includes a second motor fixed above the first fixing block, the output shaft of the second motor passing through the first fixing block and vertically fixed to a first connecting strip, and a vertical limiting shaft fixed below the first connecting strip.

[0011] Furthermore, the pushing component includes a horizontal second connecting bar, on which a second fixing block is fixed, and on which a cylinder parallel to the first connecting bar is fixed, the cylinder being located on the side of the second fixing block near the second electric telescopic rod, and the output shaft of the cylinder passing through the second fixing block and being fixed with a push plate.

[0012] Furthermore, the second connecting strip is vertically fixed to the side of the first connecting strip away from the conveying direction of the straight rolling mill exit roller table.

[0013] Furthermore, the detection assembly includes a second fixed seat fixed on the direct rolling mill exit roller track, and a distance sensor fixed on the second fixed seat. The distance sensor faces the inner side of the direct rolling mill exit roller track and is used to detect the distance between the billet and the outer edge of the direct rolling mill exit roller track.

[0014] The direct rolling mill exit roller conveyor adjustment device proposed in this invention can bring the following beneficial effects:

[0015] 1. During the process of conveying the steel billet, the pushing and straightening device of the present invention detects the distance between the steel billet and the outer edge of the track of the direct rolling mill exit roller table by a distance sensor. When the steel billet is detected to be close to the outer edge of the track of the direct rolling mill exit roller table, the corresponding pushing and straightening component is activated to push and straighten the steel billet so that it can continue to be conveyed or can smoothly enter the rolling mill.

[0016] 2. The pushing device of the present invention can adjust the pushing position of the limiting component and the pushing component by setting the adjustment component, so that the pushing device can be used to push and straighten steel billets of different lengths and steel billets at different transmission positions, and has high applicability;

[0017] 3. The pushing and straightening device of the present invention, by setting a limiting component and a pushing component, enables the steel billet to rotate around the limiting axis, which facilitates the arbitrary change of the steel billet orientation. It can not only meet the pushing and straightening needs, but also adjust the conveying direction of the steel billet according to the on-site adjustment, thereby minimizing the number of pushing and straightening operations and improving the conveying efficiency.
