Steel billet section burr removing device

Abstract

The invention discloses a steel billet section burr removing device. The device is characterized by comprising a rack, conveying roller beds, a deburring machine, a shaft, swing arm bearing blocks, bushings, a crosspiece, swing arms, oil cylinders, a pressure assisting driving arm, a pressure assisting connecting rod, pressure assisting swing suspension shafts, pressure assisting bearing blocks and a pressure assisting swing arm. The rack is provided with the swing arm bearing blocks, and the swing arm bearing blocks are connected with the shaft; shifting forks are arranged at the two ends ofthe shaft, and the shaft is connected with hinges of the extension ends of the oil cylinders through the shifting forks; the swing arms are connected with the shaft through the bushings and the crosspiece; the pressure assisting driving arm is connected with the shaft; the upper end of the pressure assisting swing arm is connected with the pressure assisting driving arm through the pressure assisting connecting rod, and the upper middle part of the pressure assisting swing arm is connected with the pressure assisting bearing blocks through the pressure assisting swing suspension shafts; the deburring machine is arranged below the rack and comprises the oil cylinders and a scraper; the conveying roller beds are arranged on the two sides of the deburring machine. The device has the advantages that the problem that burrs cannot be removed completely is solved, the burr removing rate of a continuous casting steel billet is increased, and then the percent of pass of a rolled material is improved.

Description

technical field [0001] The invention relates to a steelmaking machine, in particular to a device for removing burrs from a billet cross section. Background technique [0002] In the continuous casting production process, the continuous casting billet is cut into blocks under the action of the high-speed flame of the flame cutting machine. During the cutting process, the high-temperature steel flow forms molten steel at the bottom of the billet (the position of the slit), and hard burrs are formed after cooling. Since the burr is mainly composed of molten steel and impurities, its adhesion on the billet is very strong; this burr contains more oxide slag, which is hard and loose, with a rough and uneven surface, and may also contain some particles with extremely high hardness. [0003] At present, the scraper type deburring machine is used to deburr online during the continuous casting billet movement. The scraper type deburring machine uses the steel billet to remove the bur...

AI Technical Summary

Problems solved by technology

The scraper type deburring machine is to use the steel billet to remove the burrs by pressing the billet on the scraper when it passes through the roller table; sometimes there are short-sized red billets, due to insufficient weight and insufficient pressure, the burrs cannot be removed cleanly, if the burrs are not completely removed, Transferring to the steel rolling process will affect the quality of the rolled material, and even cause the rolled material to be rejected
