Abstract

The invention discloses a production method of an antibacterial stainless steel drainer drawn piece. The method sequentially comprises primary drawing, primary intermediate annealing, secondary drawing, secondary intermediate annealing, edge curling, coarse wire drawing and fine wire drawing; austenite stainless steel is used as a raw material, Cu ranges from 3.5wt% to 4.5wt%, C is less than or equal to 0.08wt%, Si is less than or equal to 1.0wt%, Mn is less than or equal to 2.0wt%, P is less than or equal to 0.045wt%, S is less than or equal to 0.03wt%, Ni ranges from 8wt% to 10.5wt%, Cr ranges from 17wt% to 19wt%, and the balance is Fe; the primary intermediate annealing is bright annealing, the annealing atmosphere is ammonia gas, the annealing temperature is 1,000-1,060 DEG C, and the annealing holding time is 2-10 min; the secondary intermediate annealing is bright annealing, the annealing atmosphere is ammonia gas, the annealing temperature is 1,010-1,050 DEG C, and the annealing holding time is 2-10 min. The drainer drawn piece produced with the production method has the bright, clean and flat surface and is low in cost and stable in antibacterial performance, and mass production is easy to realize.

Description

technical field [0001] The invention belongs to the technical field of bathroom product processing, and in particular relates to a method for manufacturing a stretched part of an antibacterial stainless steel drain. Background technique [0002] With the development of the economy and the improvement of people's living standards, more and more people begin to pay attention to the quality of life and physical health. Every epidemic disease causes people's panic and brings immeasurable losses to social stability and economic development. Facing the rampant viral bacteria, people study various antibiotics and actively treat them, and study various antibacterial agents on the other hand. Products that cut off the spread of bacteria from the source. Antibacterial research on metal materials began in the 1990s. After years of research, the research on antibacterial stainless steel has achieved remarkable results, and it has been applied to the kitchen and bathroom areas where mic...
