Abstract
A processing method includes processing a metal wire rod using an emulsion lubricant that includes an oil and a nonionic surfactant at an oil-to-nonionic surfactant ratio of 1:0.3 to 0.9 (in mass ratio). The method may include purifying the emulsion lubricant after being used for processing the metal wire rod while maintaining the oil-to-nonionic surfactant ratio of 1:0.3 to 0.9 (in mass ratio) and then reusing the purified emulsion lubricant to process the metal wire rod.
