Description

Technical Field

[0001] This utility model relates to the field of hot roll box technology, specifically to a 2AB roll support frame for a hot roll box. Background Technology

[0002] The hot coil box mainly consists of an inlet guide groove, deflection rollers, bending rollers, forming rollers, support rollers, stabilizers, uncoilers, pushers, as well as insulation side guide plates and pinch rollers. Installed after the roughing mill and before the flying shear, its main function is to corelessly coil the intermediate strip from the last pass of the roughing mill before uncoiling it. The intermediate strip is insulated and homogenized in coil form before entering the finishing mill, thus reducing the temperature difference between the beginning and end of the intermediate strip and maintaining a relatively uniform temperature throughout its length. The support rollers are used for uncoiling and transferring the intermediate coil (insulated coil). The horizontal movement of the support rollers ensures the coil moves along the centerline of the finishing mill, preventing strip deviation that could cause sudden changes in rolling force and strip edge stretching.

[0003] The existing support roll frame uses a tie rod as the fixing method for the 2AB roll frame bearing seat. The tie rod is a slender rod, which is fixed to the bearing seat by a fastening nut. Due to the high temperature on site, the tie rod expands due to heat, the fastening nut fails to tighten, the roll frame loosens and deforms, the center line of the roll track moves, resulting in the bearing tilting and the strip running off-center. Utility Model Content

[0004] The purpose of this utility model is to provide a 2AB support roller frame for a hot roll box, so as to solve the problem that when the existing support roller frame is used, the tie rod expands due to high temperature on site, the roller frame loosens and deforms, the center line of the roller table moves, resulting in the bearing tilting and the intermediate strip running off-center.

[0005] To achieve the above objectives, the basic solution provided by this utility model is as follows: a 2AB support roller frame for a hot roll box, comprising two bearing seats and two support rollers, a support rod fixedly connected between the two bearing seats, a plurality of transition plates fixedly connected on the support rod, each bearing seat having an installation groove A and an installation groove B, both of which are provided with mounting components for fixing the support rollers, and each bearing seat having a hydraulic cylinder mounting hole fixedly connected.

[0006] The principle and beneficial effects of this utility model are as follows: During installation, the traction roller and bearing seat are connected together by the installation component, which facilitates the installation, replacement and maintenance of the traction roller. Since the bearing seat and support rod are fixedly connected, during use, the situation where the support rod is heated and expanded due to high temperature on site, causing the center line of the roller to move and the strip in the middle to deviate can be reduced. The transition plate plays a role in transition, support or adjustment, and can prevent the steel billet from entering between the two rollers.

[0007] Option 2, a preferred option of the basic option, includes a mounting assembly consisting of a pressure cap and hex bolts. Two traction rollers are connected to mounting slots A and B respectively via the pressure cap. A round nut is movably inserted through the bearing housing, and the hex bolts movably pass through the pressure cap and are threadedly connected to the round nut. When replacing the traction rollers, the hex bolts are rotated to separate them from the round nut, the pressure cap is removed, the traction rollers are replaced, and the two new traction rollers are placed in mounting slots A and B, then secured with the pressure caps. Finally, the hex bolts are threadedly inserted through the pressure caps and connected to the round nut. This mounting assembly has a simple structure, is easy to install and maintain, and increases the service life of the device.

[0008] Option 3, a preferred option of the basic option, includes a pressure cap and a hexagon socket head cap bolt. A round nut is movably threaded through the bearing housing. Hinges are fixed to mounting slots A and B respectively, with the hinges rotatably connected to one end of the pressure cap. The hexagon socket head cap bolt movably threaded through the other end of the pressure cap and connected to the round nut. When replacing the traction roller, the hexagon socket head cap bolt is rotated to separate it from the round nut. The pressure cap is then rotated, and the traction roller is replaced by placing two new traction rollers in mounting slots A and B. The pressure cap is then rotated to press down on the traction rollers. Finally, the hexagon socket head cap bolt is threaded through the free end of the pressure cap and connected to the round nut. When replacing the traction roller, the pressure cap remains connected to the bearing housing, preventing the pressure cap from being lost.

[0009] Option 4, which is a preferred option of the basic option, has a reinforcing rod fixed between the two bearing seats, and an intermediate stiffening plate fixed between the reinforcing rod and the support rod; the reinforcing rod is fixed between the two bearing seats, which enhances the overall strength and stability of the entire drag roll frame and also increases the service life of the device.

[0010] Option 5, which is the preferred option of Option 4, features a toothed intermediate stiffening plate. The toothed shape increases the stiffness between the support rod and the reinforcing rod, thereby enhancing the bending load-bearing capacity of the support rod. When subjected to bending forces, the structure can maintain better shape stability and reduce the risk of deformation and damage.

[0011] Option 6, the preferred option of the basic option, uses a thick-walled steel pipe as the support rod. The thick-walled steel pipe is made of high-strength steel, which is not easy to deform and has a long service life. The surface of the thick-walled steel pipe is specially treated, so it has good corrosion resistance. Attached Figure Description
