The present application relates to the technical field of profile steel conveying, in particular to a forklift gantry profile steel diverging guiding device, which comprises a guiding support mechanism, a fixed-point transposition mechanism arranged on the guiding support mechanism, a profile steel width adapting mechanism arranged on the fixed-point transposition mechanism, and four sets of assisting mechanisms arranged on the profile steel width adapting mechanism; the guiding support mechanism comprises a crossbeam, a base mounted inside the crossbeam, and a bottom rail mounted inside the base. By arranging an independent guiding support mechanism on the existing steel conveying system, and arranging a fixed-point transposition mechanism on the guiding support mechanism, the profile steel is precisely clamped by the fixed-point transposition mechanism cooperating with the profile steel width adapting mechanism and the four sets of assisting mechanisms. After the clamped profile steel is rotated and lifted upward at the fixed-point position, the profile steel can be precisely put into the next conveying equipment, thereby avoiding larger angle deviation of the profile steel after being divergently guided to the next conveying system.

This utility model provides a centering device for a billet rolling mill, belonging to the technical field of steel rolling equipment structure. The centering device includes a support frame, a conveyor roller mechanism mounted on the support frame, and a transverse pusher mechanism movably mounted on the support frame. The transverse pusher mechanism includes a pair of pushers spaced apart on opposite sides of the conveyor roller mechanism, multiple swing linkages hinged at one end to the support frame, and a driving component mounted on the support frame for moving the pair of pushers closer together or further apart. By hinged at one end of the multiple swing linkages to the support frame, the driving component can move the pair of pushers closer together or further apart under the swing of the linkages. This achieves centering adjustment of the rolled piece and clamping or releasing it. The swing of the linkages effectively avoids hard contact with the rolled piece, reducing damage to the rolled piece surface.

The application discloses a high-copper seamless steel pipe skew rolling piercing manufacturing method, and production and processing manufacturing products are suitable for high-pressure boiler, petroleum chemical production and other fields. Mainly includes (1) heating temperature; (2) skew rolling piercing process parameter adjustment; the application solves the problem that high-copper steel has poor hot plasticity, and internal crack defects are caused by repeated rolling of blank temperature rise in the skew rolling piercing process, the yield is improved, the waste rate is reduced, and the contract realization rate is improved.

This utility model relates to a pusher plate for a billet rolling mill, belonging to the technical field of billet rolling mill pusher equipment in the metallurgical industry. The technical solution is as follows: it includes a base plate (1), a common panel (2), countersunk bolts (3), a wear-resistant panel (6), a connecting seat (10), and a positioning sleeve (11). One side of the base plate (1) is provided with a connecting seat (10) and a positioning sleeve (11) connected to the pusher. The other side of the base plate (1) is provided with a common panel (2) and a wear-resistant panel (6). The common panel (2) and the base plate (1) are connected together by countersunk bolts (3), and the wear-resistant panel (6) and the base plate (1) are connected together by a tenon and mortise structure (7). The beneficial effects of this utility model are: it adopts a split structure, which is firm and reliable, convenient for replacement, reduces costs, and avoids scratches on the rolled material.

The device for reversing rubber chains, as created, comprises a steel chassis (3) on which running ways (4) are mounted for moving a tensioning car (6). In parallel to the running ways (4), gear racks (5) are mounted, the drive of the tensioning car (6) being carried out by two hydraulic motors (9) by means of gears (10) meshed with the gear racks (5). At the left end of the steel chassis (3) a support (2) is fixedly mounted, and at its right end and on the tensioning car (6) a second support (2) is mounted. On the supports (2) and on the tensioning car (6) movable forks (1) are mounted, each movable fork (1) being fixed to a second gear (12) mounted on a shaft (18) bearing in bearing bodies (21) and on which second gear (12) is fixed a bracket (14) to which a balance weight (13) is mounted. Each movable fork (1) comprises a fixed arm (15), a movable arm (16) and a locking arm (17), the rotation of the movable forks (1) being carried out by two other hydraulic motors (23) by means of third gears (11) mounted on the shafts of the other hydraulic motors (23) and meshed with the second gears (12) mounted on the shafts (18) of the movable forks (1).
