The invention provides a manufacturing method of austenitic stainless steel suitable for surface embossing. The manufacturing method comprises the steps that a raw material black coil is sequentially subjected to annealing, scale breaking, shot blasting and acid pickling work through a hot rolling annealing and acid pickling unit, and then the raw material black coil is manufactured into a No.1 plate; cold rolling work is carried out on the No.1 plate through a rolling mill of a production unit, and the No.1 plate is manufactured into a cold-rolled coil; the cold-rolled coil is sequentially subjected to annealing and pickling work through a cold plate annealing and pickling unit, and then the cold-rolled coil is manufactured into a cold-rolled stainless steel 2D surface; the cold-rolled stainless steel 2D surface is sequentially subjected to flattening, edge cutting, roll dividing and warehousing work through a finished product unit; and the cold-rolled stainless steel 2D surface subjected to warehousing in the step A4 is subjected to sample inspection work. According to the manufacturing method of the austenitic stainless steel suitable for surface embossing, the cold-rolled stainless steel 2B surface which is low in strength, uniform in surface color, straight in plate shape and small in thickness tolerance can be produced, and the austenitic stainless steel suitable for surface embossing can be stably used for high-end embossing machining work.
Description
technical field [0001] The invention belongs to the application field of stainless steel cold-rolled products, and in particular relates to a method for manufacturing austenitic stainless steel suitable for surface embossing. Background technique [0002] With the continuous development of the economy, stainless steel is more and more widely used, and stainless steel embossed plates are becoming more and more popular, and are widely used in high-end decorative purposes, food and drug industries, etc. Stainless steel embossed plate is based on cold-rolled stainless steel plate, through the action of embossing rollers, the stainless steel surface has a specific pattern, to achieve the effect of decoration or increase strength, increase friction, stainless steel surface embossed products are not only beautiful in appearance In addition, it also has the characteristics of increasing the strength of the steel plate, and its impact resistance and compression resistance are superio...
