High-speed steel cold-rolled sheet production process

Abstract

The invention belongs to the technical field of cold-rolled sheets, and relates to a high-speed steel cold-rolled sheet production process which comprises an acid pickling shell, three acid pickling cavities are formed in the acid pickling shell, and an auxiliary mechanism, a first moving mechanism, a cleaning mechanism, a second moving mechanism, a scraping mechanism and a recycling mechanism are arranged in each acid pickling cavity. Meanwhile, multiple pieces of high-speed steel can be subjected to acid pickling work through the multiple acid pickling cavities, the mechanical arms and the conveying belt at the same time, the acid pickling work efficiency is improved, and through the full-mechanical automatic acid pickling work process, the labor cost of a factory is reduced; and oxide removal work can be conducted on the bottom wall of the periphery of the high-speed steel through the scraper, the situation that the high-speed steel needs to be turned over manually, and the pickling efficiency is reduced is avoided, finally, pickling liquid is recycled and used repeatedly through the infusion pump, and the production cost of a factory is reduced.

Description

Technical field [0001] The invention involves the field of cold -rolled sheet technology, which is specifically a high -speed steel -cold -rolled sheet production process. Background technique [0002] Cold -rolled thin steel plate is the abbreviation of ordinary carbon structure steel cold -rolled plates. Cold plates are steel hot rolled tapes from ordinary carbon structures, which are further cold -rolled into steel plates with a thickness of less than 4mm. Due to rolling at room temperature, no iron oxide skin is produced, so the surface quality of the cold plate is good, the size is high, and the annealing treatment is better than the hot -rolled steel plate. In the field of home appliance manufacturing, it has gradually replaced the hot -rolled thin steel plates, but there are several defects in the existing production process: [0003] First, when the existing pickle machine is possibly picked the high -speed steel surface, the pickled machine cannot quickly pick up the upp...

AI Technical Summary

Problems solved by technology

[0003] First, when the existing pickling machine pickles the surface of the high-speed steel, the pickling machine cannot quickly pickle the upper and lower sides of the high-speed steel. Pickling the steel plate reduces the pickling efficiency and increases the labor cost of the factory;

[0004] Second, during pickling, most of the oxide layer will stay on the surface of the steel plate after cleaning, and the oxide cannot be separated from the surface of the steel plate in time, which increases the consumption of pickling liquid and increases the cost of pickling;

[0005] Third, workers are required to cooperate with the equipment, and long-term contact with steel plates with pickling liquid is likely to cause harm to the body, which increases the labor cost of the factory and increases the risk of worker injury
