Abstract:
Herein disclosed is a dry type continuous wire drawing process which can retain satisfactory working circumstances while eliminating the problem of disposal of waste liquids. The wire drawing process includes the steps of descaling a wire to be drawn, coating the descaled wire with a lubricant, and drawing the lubricant-coated wire through a drawing die. The descaling step is conducted in a mechanical manner. At the lubricant coating step, the descaled wire is once coated with lime powder and then with metallic soap powder. Thus. the three steps recited are conducted under dry and continuous conditions. At the lubricant coating step, the lime-coated wire may be coated with powder of sodium stearate before it is coated with the metallic soap.

Abstract:
A process for drawing wire employing a lubricant comprising perfluorocarbon compounds (PFCs), including aliphatic perfluorocarbon compounds ( alpha -PFCs) having the general formula CnF2n+2, perfluoromorpholines having the general formula CnF2n+1ON, perfluoroamines (PFAs) and highly fluorinated amines (HFAs), and perfluoroethers (PFEs). Such fully and highly fluorinated carbon compounds exhibit a very high degree of thermal and chemical stability due to the strength of the carbon-fluorine bond. Further, because the compounds are fully fluorinated, and therefore do not contain chlorine and bromine, they have zero ozone depletion potential (ODP). Further, because the compounds are photochemically non-reactive in the atmosphere, they are not precursors to photochemical smog and are exempt from the United States Environmental Protection Agency (EPA) volatile organic compound (VOC) definition. Further, because they are volatile, the compounds are easily removed at the end of the process without need for an additional cleaning step. The process provides wire at significantly higher production speeds and longer die life with improved quality and less byproduct debris.
Abstract translation:一种使用包含全氟化碳化合物(PFC)的润滑剂的方法,该润滑剂包括具有通式C n F 2n + 2的脂族全氟化碳化合物(α-PFC),具有通式C n F 2n + 10N的全氟吗啉,全氟胺(PFA) HFAs)和全氟醚(PFE)。 这种完全和高度氟化的碳化合物由于碳 - 氟键的强度而表现出非常高的热和化学稳定性。 此外,由于这些化合物是完全氟化的,因此不含氯和溴,因此它们具有零臭氧消耗潜能值(ODP)。 此外,由于化合物在大气中是光化学非反应性的,它们不是光化学烟雾的前体,并且不受美国环境保护局(EPA)挥发性有机化合物(VOC)定义的限制。 此外,因为它们是挥发性的,所以在过程结束时容易除去化合物而不需要额外的清洁步骤。 该工艺以更高的生产速度和更长的模具寿命提供焊丝,同时改善质量和减少副产品碎片。
