Abstract

The invention belongs to the field of metallurgical equipment, in particular to a hydraulic steel pushing and turning method in a section steel hot rolling operation line. The oil cylinder (1) pushes the push plate (2) to slide on the slide track (3) of the push plate, which can be single-action or synchronously moved to make the profile reach the required position; there is a group of lifting cylinders (5) inside the groove frame (10) ) and a group of overturning cylinders (6), the cylinder body of the lifting cylinder (5) can move up and down on the sliding track, and the cylinder body of the overturning cylinder (6) can also move up and down on the sliding track, and the lifting cylinder (5) and the overturning cylinder (6) respectively Control the overturning hook (8), the lifting cylinder (5) controls the rising and falling of the overturning hook (8), and the overturning cylinder (6) controls the overturning hook (8) to overturn, so as to realize the 90° overturn of the hot-rolled billet and complete the steel overturning action . It occupies a small area, low cost, high reliability, light weight and compact structure.

Description

technical field [0001] The invention belongs to the field of metallurgical equipment, in particular to a hydraulic steel pushing and turning method in a section steel hot rolling operation line. Background technique [0002] In the hot rolling line, the blanking of medium-section steel and the blanking of medium and heavy plates are replaced by flat roll rolling instead of vertical roll rolling. Pushing steel and turning steel are one of the essential equipment components. At present, the steel pushing and turning methods in the domestic hot rolling operation line are all mechanical pushing and turning methods, which have the disadvantages of high investment, large floor space and low reliability. Contents of the invention [0003] The object of the present invention is to provide a hydraulic method for pushing and turning over steel with small footprint, low cost, high reliability, light weight and compact structure. [0004] The object of the present invention is achiev...
