Embodiment Construction

[0016] The medical stainless steel production process includes the following steps:

[0017] a. Grinding of steel wire, grinding the defects, stitches, cracks and burrs of the raw steel wire;

[0018] b. Coating, the steel wire after grinding is coated with a coating agent, the temperature of the coating is 90°C-95°C, and the time is 12-18min; generally 90°C or 93°C or 95°C, the time is 12 or 15 or 18min, The function of the coating agent is to make the steel wire rough, so that it can fully contact with the wire drawing powder during drawing, and absorb the wire drawing powder through the coating agent. At the same time, the coating agent also has the function of lubricating during drawing. The coating agent is a commonly used material in the wire drawing industry. known;

[0019] c. Drying. Since the coating agent is wet, the coated steel wire is dried in an oven at 100-110°C. The general drying temperature is 100°C, or 105°C or 110°C. The drying is for Hardened coating ag...

Abstract

The invention belongs to the field of medical instruments, and particularly relates to a medical stainless steel production technology. The medical stainless steel production technology comprises the following steps: coping of steel wires, enveloping, drying, rough drawing, annealing, winding for checking and then coating of a lubricant agent, drying or air-drying after the lubricant agent is coated, and finish drawing. The medical stainless steel production technology has the advantages of being simple in technology, high in drawing toughness and good in effect used for medical stainless steel.

Description

technical field [0001] The invention belongs to the field of medical equipment, in particular to a production process of medical stainless steel. Background technique [0002] The general composition of stainless steel is a combination of elements such as iron, chromium and carbon. Household stainless steel can be divided into three grades: 430, 304 (18-8), and 18-10. 430 stainless steel: the chromium more than iron+12% can prevent the oxidation that natural factor causes, be referred to as stainless steel, be No. 430 at the code name of jis, therefore be called 430 stainless steel again. However, 430 stainless steel cannot resist the oxidation caused by chemical substances in the air. After a period of infrequent use, 430 stainless steel will still be oxidized (rusted) due to unnatural factors; 18-8 stainless steel: iron + 18% chromium +8% nickel, which can resist chemical oxidation. This stainless steel is No. 304 in the jis code, so it is also called 304 stainless steel...
