An in-furnace conveying device with good anti-black mark effect for round steel heating furnace

Abstract

The invention belongs to the technical field of heating furnaces, in particular to a conveying device in the furnace with good anti-black mark effect for the round steel heating furnace, aiming at the lower surface of the crossbeam supporting rod always in contact with the steel billet when the existing heating device is feeding in the furnace The contact of the lower surface will easily lead to the problem of uneven heating of the steel billet. The following scheme is proposed, including a movable beam and a fixed beam with a square tubular structure. The bottom of the fixed beam is fixed with a C-shaped steel slide rail with an upward opening, and the C-shaped steel A slide bar is slidably connected in the slide groove of the slide rail, and a wave bar is fixed on the upper surface of the slide bar. When the present invention is in use, when the steel billet body is placed between the first jacking block and the second jacking block, the first ejector pin and the second ejector pin can be driven up alternately by pushing the sliding bar to the left and right and then cooperating with the wave bar. top, so that the billet body can move back and forth between the first top block and the second top block, avoiding the uneven heating caused by the lower surface of the billet body contacting the upper surface of the fixed beam for a long time.

Description

technical field [0001] The invention relates to the technical field of heating furnaces, in particular to an in-furnace conveying device for a round steel heating furnace with good anti-black mark effect. Background technique [0002] The existing walking beam of the heating furnace has a structure consisting of beams, columns and cooling water pipes, which are welded as a whole and cannot be separated from each other. The installation method is to install the beams, columns and cooling water pipes in the furnace first, and then use the mold to pour or pound refractory materials around the water pipes to wrap the water beams to reduce the hot steel billet and the high temperature in the furnace. Damage to cooling water pipes. In actual production, due to the irrationality of the structure of the walking beam, the billet is prone to black marks at the position where it touches the beam. [0003] After searching, the Chinese patent number is CN201921100091.0, which discloses...
