Light-and-thin-kind waste steel recycling method

Abstract

The invention belongs to the technical field of waste steel recovery, and particularly relates to a light-and-thin-kind waste steel recycling method. A waste steel machining device comprises a smashing tank, a rotating cleaning device and a crushing device, a driving motor is arranged on the outer wall of the top end of the smashing tank, moreover, the output end of the driving motor is connectedwith a driving shaft, moreover, the bottom end of the driving shaft penetrates through the top end wall of the smashing tank to be connected with a driving gear, a double-face gear disc and the driving gear are in internal meshed connection for transmission, a driven gear and the double-face gear disc are in external meshed connection for transmission, the bottom end of the driving gear and the bottom end of the driven gear each are connected with a rotating shaft, moreover, the rotating shafts are sleeved with cleaning rollers, a plurality of cleaning brushes are uniformly arranged on the outer wall of each cleaning roller, rotating worms are rotationally connected to the bottom ends of the rotating shafts, moreover, rotating worm wheels are rotationally meshed on the rotating worms, theouter walls of rotating columns are sleeved with crushing rollers, and crushing blocks are obliquely arranged on the crushing rollers. The situation that soil or plastic sundries bonded on a steel pipe influence recycling of the light-and-thin-kind steel pipe is prevented, and the recycling rate of the steel pipe is increased.

Description

technical field [0001] The invention belongs to the technical field of scrap steel recycling, in particular to a method for recycling light and thin scrap steel. Background technique [0002] Light and thin steel scrap is mainly produced in steelmaking workshops, steel casting workshops, and steel cold processing workshops; with the technological development of light and thin steel production, the yield of light and thin steel products has increased, and the proportion of self-produced light and thin steel scrap in steel output has reached The downward trend; daily necessities light and thin scraps such as cans, furniture and appliances, etc., are called social scrap or garbage scrap. [0003] The recycling and utilization of existing steel scraps are mainly supplied to steelmaking converters for recycling; light and thin steel scraps in steel scraps have a light specific gravity and float up during the converter smelting process, resulting in a low scrap recovery rate and a...

AI Technical Summary

Problems solved by technology

[0003] The recycling of existing steel scrap is mainly to supply steelmaking converters for recycling; light and thin steel scraps in scrap steel have a light specific gravity and float up during the converter smelting process, resulting in a low scrap recovery rate and affecting the recycling efficiency of scrap steel; at the same time, light and thin steel scraps When scrap steel is recycled, since there are many soil or plastic debris bonded to the surface of the scrap steel, and then supplied to the steelmaking converter for steelmaking, the debris bonded to the scrap steel will easily cause debris to appear in the smelted steel, and then It affects the quality and efficiency of steelmaking, and at the same time affects the safety of steelmaking converters
