Bidirectional material taking device, using method and application

Abstract

The invention discloses a bidirectional material taking device, a using method and application, relates to the technical field of steel rolling in the metallurgical industry, and aims to solve the problems that a waste removing device is adopted for removing a direct-rolled continuous casting billet with the temperature problem in the continuous casting billet direct rolling process, in order to avoid occupying extra space, steel is likely to be used as waste steel to enter an electric furnace for steelmaking or be used as a cold billet to be treated when being stacked near a waste material pile or a cold billet pile. The bidirectional material taking device comprises a collecting rack arranged on one side of a conveying roller way, a steel shifting machine is further arranged below the collecting rack, and steel shifting forks are movably installed on the steel shifting machine and used for enabling materials to move between the end, close to the conveying roller way, of the collecting rack and the conveying roller way. A steel pushing machine is further arranged on the side, away from the conveying roller way, of the collecting rack and provided with a pushing device used for pushing the materials on the collecting rack to the steel shifting forks. The bidirectional material taking device is simple in structure, compact in action, capable of meeting the technological requirements, capable of being used as a common waste rejecting device, capable of being used for feeding cold / hot blanks and wide in application range.

Description

technical field [0001] The invention relates to the technical field of steel rolling in the metallurgical industry, in particular to a two-way reclaiming device, a use method and an application. Background technique [0002] The reject device is an important process equipment in the steel rolling production line. It can be used in the rolling area behind the furnace to remove the unqualified billets from the roller table to avoid entering the rolling mill. It can also be arranged in the furnace front area, especially when hot billets and cold billets When the billets are mixed, it is necessary to remove the unqualified cold / hot billets outside the furnace to avoid damage to the furnace body and the stepping machinery. The patent and the utility model patent with the announcement number CN206570375U and titled "Slab Production Line Suitable for Heating Furnace" both disclose waste rejecting devices of different structures, which include a stand installed on one side of the ro...
