There are several different wire drawing lubricants used for steel wire rod, including soap-based lubricants, oil-based lubricants, and synthetic lubricants. Soap-based lubricants are commonly used for mild steel wire rod, as they provide good lubrication and cooling properties. Oil-based lubricants are often used for high carbon and alloy steel wire rod, as they offer better lubrication and reduce friction during the drawing process. Synthetic lubricants, such as water-based polymer lubricants, are also used to improve surface finish and reduce wear on the wire rod during drawing.
