Problems solved by technology

At present, the lubricating emulsified oil for drawing thick-walled bearing steel pipes has the problems of poor cleaning performance and poor cooling effect, so that after many times of drawing, a large amount of metal powder adheres to the surface of the drawn tube and the edge of the hole core, resulting in two The friction coefficient between the two increases sharply, which not only reduc

Abstract

The invention discloses thick-wall bearing steel pipe drawing lubricating emulsifying oil, which consists of the following raw material components in percentage by mass: 1-15 percent of oleic acid, 1-8 percent of barium mahogany sulfonate, 1-8 percent of lead naphthenate, 10-20 percent of chlorinated paraffin, 10-20 percent of 2,6-butylated hydroxytoluene, 1-4 percent of triethyl phosphate, 1-4 percent of dibutyl phthalate, 1-6 percent of zinc dialkyl dithiophosphate, 1-6 percent of polyvinyl butyl ether and the balance transformer oil. A production method of the emulsifying oil comprises the following steps of: adding the transformer oil into a reaction kettle, and heating to 40-50 DEG C; starting a stirrer and controlling the rotating speed at 40 revolutions per minute; slowly and sequentially adding barium mahogany sulfonate, lead naphthenate, oleic acid, chlorinated paraffin, triethyl phosphate, dibutyl phthalate, T501, T202 and T601 into the reaction kettle, wherein a next raw material is added till a previous raw material is fully dissolved by stirring; after all raw materials are dissolved, continually stirring for 1 hour; and discharging and packaging.

Description

technical field [0001] The invention relates to a lubricating emulsified oil for drawing process and its production method, in particular to a drawing lubrication for thick-walled bearing steel pipes which can prevent local overheating of the drawn metal pipe, oxidative discoloration, and ensure the surface finish and brightness of the finished product. Emulsified oil and 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 emulsified oil is required to lubricate and cool the metal material and mold. Lubricating emulsified oil plays a vital role in such a huge extrusion a...
