Wire Drawing Powder
Wire drawing powder is a lubricating material used to draw wire rods, such as low-carbon steel wire, high-carbon steel wire, stainless steel wire, etc. Its ingredients usually include calcium hydroxide, sodium hydroxide, stearic acid, animal fats, vegetable fats, paraffin, industrial soap, talcum powder, industrial alkali, etc. Its function is to form a lubricating film on the surface of the wire during the cold wire drawing process, reduce the friction between the wire and the drawing die, extend the service life of the die, reduce wire breakage and surface defects during the drawing process, and improve the surface finish and consistency of the wire.
Types and Characteristics of Wire Drawing Lubricant Powder for Wire Drawing
Wire Drawing powder is mainly divided into two categories: sodium-based and calcium-based. Sodium-based drawing powder has a high oil content and good lubrication effect and is suitable for high-strength and high-speed drawing processes. Calcium-based drawing powder has a lower oil content and is usually used for lower-strength drawing processes. Sodium-based drawing powder maintains excellent lubricity under high-temperature and high-pressure conditions, does not easily corrode steel wire, and is easy to remove. Calcium-based drawing powder performs better under low-temperature conditions and is more suitable for economical drawing processes.
Features of Wire Drawing Powder
Drawing powder can be firmly adsorbed on the surface of the wire and then enter the wire drawing die, effectively separating the wire from the wire drawing die, extending the service life of the wire drawing die, and ensuring the surface quality of the wire.
Under the high pressure and temperature rise conditions generated during drawing, the lubricating film can maintain continuity and lubricity without being destroyed or agglomerated.
It can not only be firmly adsorbed on the surface of the wire but also can be extended and deformed with the wire, reducing wire breakage during wire drawing.
Drawing powder will not react chemically with the wire, will not corrode the wire, and is easy to remove.
Drawing lubricating powder does not pollute the environment, is harmless to the human body, has low cost, and is easy to store.
Different Wire Drawing Powders Suitable for Different Wire Drawing Machines and Wire Types
For different wire drawing machines (such as pulley type wire drawing machines and straight line wire drawing machines) and different wires (such as SAE1008, SAE1016, SAE1030), wire drawing powder is also different. In the wire drawing process, the better the oiliness of the wire drawing powder, the better the lubrication performance, and the color of the cold-drawn wire will become black and shiny. Generally speaking, the higher the oil content of the wire drawing powder, the more expensive it is.
