Generally, drawing powder should have the following properties:
(1) it can be firmly adsorbed on the surface of steel wire.
(2) Resistance to high pressure and high temperature, under the conditions of high pressure and temperature rise generated during drawing, the lubrication film can still maintain its continuity and lubricity without being destroyed or caking, that is, it has physical and chemical stability.
(3) It has good extensibility and lubricity.
(4) The components of drawing powder will not react with steel wire matrix, generate compounds that affect the properties of steel wire, or corrode the steel wire, and it is easy to remove.
(5) It does not pollute the environment, and harmless to human body, low cost and easy to preserve.
