Problems solved by technology

At present, the stainless steel tube drawing lubricating emulsified oil 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 a gap between the two. The friction coefficient between them increases sharply, which not only sharply reduces the surface finish and brightness of the drawn workpiece, but also aggravates the wear on the mold and affects the service life of the mold; in addition, the cooling effect is not ideal, and it often occurs due to local overheating of stainless steel pipes or molds. Quality problems of broken tubes
In addition, due to poor cleaning performance, it will have a negative impact on the quality of heat treatment and annealing in the subsequent process of drawing metal pipes

Abstract

The invention discloses lubrication emulsified oil for stainless steel tube drawing, which comprises the following raw materials in weight percentage: 5-15 percent of chlorinated paraffin, 1-5 percent of 2,6-butylated hydroxytoluene, 1-5 percent of zinc dialkyl dithiophosphate, 1-10 percent of poly-vinyl butyl ether, 1-12 percent of oleic acid, 1-12 percent of triethanolamine, 1-8 percent of lead naphthenate, 1-6 percent of butyl phthalate, 1-26 percent of LN46 machine oil and the balance transformer oil. A production method for the lubrication emulsified oil for the stainless steel tube drawing comprises the following steps of: adding the machine oil and the transformer oil into a reaction kettle in sequence; heating to 40-50 DEG C; starting a stirrer; and then, slowly adding the chlorinated paraffin, the oleic acid, the triethanolamine, the lead naphthenate, the butyl phthalate, the 2,6-butylated hydroxytoluene, the zinc dialkyl dithiophosphate and the poly-vinyl butyl ether into the reaction kettle in sequence, wherein each time a kind of material is added, the raw materials are independently stirred for 10-30 min; continuously stirring for 2h after all the raw materials are added; and blowing 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 stainless steel pipe drawing lubricating emulsified oil which can prevent local overheating of the drawn metal pipe, break the pipe, oxidize and discolor, and ensure the surface finish and brightness of the finished product. and production methods. 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 and...
