Steel plate blank heat preservation vehicle

Abstract

The invention relates to steel equipment, in particular to a steel plate blank heat preservation vehicle. The steel plate blank heat preservation vehicle comprises a plurality of longitudinally-arranged plate blank stacking positions, every two plate blank stacking positions form a group, guide rails are arranged on the two sides of each plate blank stacking position, the upper surfaces of the guide rails are lower than the lower surfaces of first-layer steel plate blanks of the plate blank stacking positions, a first heat preservation vehicle and a second heat preservation vehicle corresponding to the first and second plate blank stacking positions are arranged on the guide rails, the distance between every two adjacent sets of plate blank stacking positions is larger than the length of the first heat preservation vehicle, the first heat preservation vehicle comprises an inverted-U-shaped vehicle body, wheels matched with the guide rails are arranged at the bottoms of the two sides ofthe vehicle body, outer end heat preservation doors fixedly connected with the foundation are arranged at outer end openings of the first heat preservation vehicle and the second heat preservation vehicle, a middle heat preservation door fixedly connected with the foundation is arranged between the first heat preservation vehicle and the second heat preservation vehicle, the first heat preservation vehicle and the second heat preservation vehicle are movably connected through an interlocking mechanism, and the inner end of the second heat preservation vehicle is fixedly connected with a driving mechanism on the outer side of the guide rails through a support arm connecting mechanism. According to the steel plate blank heat preservation vehicle, the temperature loss of the steel plate blank during storage is prevented, the heating cost is saved, and the cost is reduced.

Description

technical field [0001] The invention relates to iron and steel equipment, in particular to a steel slab heat preservation vehicle. Background technique [0002] At present, nearly 50% of the slabs in most iron and steel enterprises cannot be continuously hot delivered after they are rolled off the continuous casting line, and are stacked on the slab bridge. The temperature of the steel slab off-line is 800-850°C, a large amount of heat energy is naturally dissipated, and the heat content is about 567KJ / Kg. When it is transported to continuous rolling, the heating furnace reheats the steel slab, and hot rolling is carried out when it reaches the process temperature of about 1200°C . In the stacking process of steel slabs, a large amount of high-temperature waste heat has not been recycled, resulting in energy waste. Contents of the invention [0003] The present invention aims to solve the above-mentioned technical problems, and provides a steel slab heat preservation car...
