Problems solved by technology

At present, oil-based lubricants are used for fine drawing of nickel-chromium stainless steel, but the formed lubricating film has poor adhesion and is easily squeezed out during the drawing process. The friction coefficient between the surface of the drawn wire and the edge of the hole core increases sharply, which not only sharply reduces the surface finish and brightness of the drawn workpiece, but also aggravates the wear and tear on the mold, affecting the service life of the mold; in addition, there are cooling effects and cleaning The problem of unsatisfactory performance, poor cooling effect often leads to quality problems of broken wires due to local overheating of metal wires or molds; poor cleaning performance, not only is it easy to bond a large amount of material on the surface of the drawn wire and the edge of the hole core during the drawing process The metal powder will further increase the friction coefficient between the two, and will have a negative impact on the heat treatment and annealing quality of the subsequent process of drawing the metal wire.

Abstract

A high-speed pulling lube cooling oil of nickel-chromium stainless steel wire consists of oleic acid 4-6wt%, motor oil 20-30wt%, castor oil 8-12wt%, chlorinated paraffin 30-40wt%, mersolates 4-6wt%, aluminum naphthenate 4-6wt%, phosphinothioyl buoctyl-zinc salt 8-12wt%, poly-n-butyl vinyl ether 4-6wt% and bactericide 0.1-0.2wt%. The process is carried out by adding motor oil and chlorinated paraffin into reactor successively, heating to 70-80degree, agitating at 480-500 / min, adding into mersolates, aluminum naphthenate, oleic acid and bactericide, agitating for 0.5-1.5hrs, lowering temperature to normal temperature, adding into phosphinothioyl buoctyl-zinc salt and poly-n-butyl vinyl ether and agitating at 30-40 / min for 1-3hrs. It can prevent pulling metal from overheat and oxidation coloring and have better finish degree and brightness.

Description

Technical field: [0001] The invention relates to a lubricating cooling liquid for drawing process and a production method thereof, in particular to a high-speed drawing of nickel-chromium stainless steel wire which can prevent local overheating of the drawn metal wire, oxidative discoloration and ensure the surface finish and high brightness of the finished product. Lubricating and cooling oil and its production method. Background technique: [0002] The drawing process is a typical metal processing method. It is a plastic processing process that reduces the cross-sectional area of ​​the metal processing material through the die hole core under the action of drawing to obtain a high-precision, high-gloss wire or pipe. During the drawing process, due to the large amount of metal deformation and the continuous generation of new friction surfaces, lubricating coolant is required to lubricate and cool the metal material and mold. In particular, the fine drawing process of nicke...
