PROBLEM TO BE SOLVED: To provide a high performance dry drawing wire lubricant which can be used under harsh conditions of high temperature, high pressure, and high speed, which can cope with a wide range of wire diameter reduction from a small diameter to a large diameter and also a wide range of linear speed from high speed to low speed, and which is excellent in lubricative property, followability, spreading property, adhesive property, heat resistance property, processability, workability, safety, and durability, and so on.SOLUTION: A dry drawing wire lubricant comprises a mixture of a metal soap of saturated aliphatic monocarboxylic acid, and a metal soap of linear aliphatic dicarboxylic acid. The dry drawing wire lubricant comprises the metal soap mixture in a state where the metal soap of saturated aliphatic monocarboxylic acid and the metal soap of linear aliphatic dicarboxylic acid are mixed in a solid condition, respectively, and/or at least a portion of either one of both soaps may be contained in the other in a solid solution condition. The metal soap mixture may be contained in an amount of 30-80 mass% in the dry drawing wire lubricant.SELECTED DRAWING: None 【課題】高温、高圧、高速下の過酷な伸線加工条件で使用でき、細径から太径までの幅広い線径への縮径や、低速から高速までの幅広い線速にも対応でき、潤滑性、追随性、展着性、付着性、耐熱性、加工性、作業性、安全性、耐久性等に優れた高性能の乾式伸線用潤滑剤を提供する。【解決手段】乾式伸線用潤滑剤は、飽和脂肪族モノカルボン酸の金属石鹸と直鎖脂肪族ジカルボン酸の金属石鹸との金属石鹸混合物が含まれている。乾式伸線用潤滑剤は、前記金属石鹸混合物が、前記飽和脂肪族モノカルボン酸の金属石鹸と前記直鎖脂肪族ジカルボン酸の金属石鹸とが、夫々の固体状態で混合されており、及び／又は一方の少なくとも一部が他方に固溶状態で混合されてもよく、前記金属石鹸混合物が、３０〜８０質量％含まれていてもよい。【選択図】なし
