Steel pipe cold drawing oil

Abstract

The present invention relates to a steel pipe cold drawing oil, which comprises the following raw material components by weight: 1-3% of an extreme pressure agent 1, 1-5% of an extreme pressure agent2, 3-8% of trimethylolpropane oleate, 1-2% of a wear-resistant agent, 0.5-1.5% of oil-soluble alkyl phosphate, 0.2-1.0% of an anti-rust agent, and the balance of base oil. The steel pipe cold drawingoil of the present invention has excellent extreme pressure lubrication performance and extremely low friction coefficient, and is suitable for the cold drawing process of stainless steels, carbon steels, alloy steels and other difficultly-processed pipes.

Description

technical field [0001] The invention belongs to the field of chemical products, in particular to a steel pipe cold drawing oil. Background technique [0002] High-precision cold-drawn steel pipe is a precision pipe made of hot-rolled seamless pipe or longitudinally welded pipe as a blank, which is plastically deformed by extrusion on a high-precision cold-drawing machine after pretreatment. This kind of pipe not only has high dimensional accuracy and good surface roughness, but also has high mechanical strength (compared with the original material hot-rolled pipe), and can be directly or honed to make oil cylinder or cylinder block. At the same time, the difficult problem that the traditional method cannot be used to process the slender and thin-walled cylinder body is solved. The high-precision cold-drawn steel pipe adopts a non-cutting process. Compared with traditional crafts, it saves labor and materials, can greatly save energy and raw materials, and has very signific...
