Pickling-replaced strip steel surface dephosphorization production line

Abstract

The invention discloses a pickling-replaced strip steel surface dephosphorization production line. The pickling-replaced strip steel surface dephosphorization production line comprises a strip steel decoiling device, a leveling device, a rough polishing oxidation layer device, a shot blasting machine assembly device, a polishing wheel assembly device and a strip steel coiling device which are sequentially arranged from an upstream position to a downstream position of the production line; a material storage box is arranged between the leveling device and the rough polishing oxidation layer device; the shot blasting machine assembly device comprises a group of coarse-to-fine shot blasting machines; 3-6 shot blasting machines are arranged; 2-15 groups of polishing wheels are arranged. According to the pickling-replaced strip steel surface dephosphorization production line, the strip steel can be leveled; the rough polishing oxidation layer device is used for roughly polishing the strip steel surface oxide skin; the shot blasting quantity of the shot blasting machine assembly device is greatly increased; the shot blasting machine assembly device has the functions of finely processing and polishing the surface of the strip steel; the polishing wheel assembly device is used for removing impurities on the surface of the strip steel; meanwhile, the purpose of cold pressing the strip steel is achieved; the conventional pickling production line is replaced; the pickling-replaced strip steel surface dephosphorization production line is environment-friendly and free of pollution; the production efficiency is increased by 10%; the production cost is reduced by 20-30%.

Description

technical field [0001] The invention relates to the technical field of metal processing, in particular to a production line for replacing phosphorus removal on the surface of pickling strip steel. Background technique [0002] Strip steel is a narrow and long steel plate produced by various steel rolling enterprises to meet the needs of industrial production of various metal or mechanical products in different industrial sectors. Cold-rolled steel strips and thin plates generally have a thickness of 2-3mm and a width of 100-800mm; both use hot-rolled steel strips or steel plates as raw materials, and are rolled into products by cold rolling mills at room temperature. Pickling of strip steel is an important process in the production process of strip steel. In the traditional pickling production line, a dense oxide film is formed on the surface of the strip steel after high-temperature annealing treatment. Pickling can easily cause serious environmental pollution. Contents ...
