Turning and guide device for square billets

Abstract

The invention relates to the field of roller bed conveying position control prior to square billet rolling, in particular to a turning and guide device for square billets. The turning and guide device is characterized by comprising a lifting cylinder, a lifting seat, a guide rail, a movable baffle and a fixed baffle. The end of a piston rod of the lifting cylinder is connected to the middle of the bottom of the lifting seat. A hinge seat is disposed in the middle of the top of the lifting seat. The fixed baffle is disposed on one side of the hinge seat and connected with a base. The lower portion of an operating lever is hinged with the hinge seat. The lower end of the operating lever is hinged with one end of an oscillating bar. A slider is disposed at the other end of the oscillating bar. A horizontal slide groove is arranged on the guide rail. The movable baffle is disposed on the slider. Compared with the prior art, the turning and guide device has the advantages that turning and guidance of square billets or rectangular billets with severe bending and large deflection can be completed instantly by gently switching the operating lever; and the turning and guide device can be mounted between a discharge roller bed and a feed roller bed, two turning and guide devices can be evenly distributed between billets 3-7m in length, and three turning and guide devices can be evenly distributed in the billet length range for billets 7-12m in length.

Description

technical field [0001] The invention relates to the field of position control of a billet before being rolled, and particularly relates to a billet turning and guiding device. Background technique [0002] At present, a considerable part of the factories and mines in the hot rolling industry use billets and rectangular billets as raw materials to roll rods, wires and narrow strip products. This type of steel products accounts for more than 40% of the current domestic steel products, and the specifications of billets are mostly in In the range of 90×90mm~180×180mm, the rectangular blank is in the range of 120×180mm~180×225mm. [0003] In the process of organizing the production of various steel mills, due to the absence of the upper straightening process, the square billet or rectangular billet used as raw material is seriously bent and has a large deflection. The baffle will cause damage to the furnace mouth and the roller table baffle, causing potential safety hazards. Ev...

Problems solved by technology

[0003] In the process of organizing the production of various steel mills, due to the absence of the upper straightening process, the square billet or rectangular billet used as raw material is seriously bent and has a large deflection. The baffle will cause damage to the furnace mouth and roller baffle, causing safety hazards

The billet or rectangular billet with severe bending and large deflection will deviate seriously even if it is put into the furnace, and the curved hot billet is even more hidden dangers in the process of being discharged from the furnace
