Problems solved by technology

Due to the existence of water on the surface of the copper material during use, it is very easy to cause corrosion and discoloration on the surface of the copper strip. At the same time, because the emulsification and dispersion of some components are not easy to stabilize, the annealing and volatilization after rolling is not complete, and stains are easy to remain on the surface of the strip, which affects the product. Quality; ingredients that are corrosive to the strip in the traditional lubricating fluid formula, such as: oleic acid, triethanolamine, etc.

Embodiment

[0014] When the copper product grade is TFE0.1 and the batch number is 0661032 strip, the thickness of the entrance is 14.0mm, and the thickness of the exit is 1.5mm, and the rolling is completed in 7 rolling passes. It is made by mixing 11% of 32# general-purpose engine oil, 55% of 7# general-purpose engine oil, 8% of sodium petroleum sulfonate, 11% of emulsifier, and 7% of white oil. In the preparation of lubricating fluid, first add 7# general-purpose motor oil to 32# general-purpose motor oil; then add sodium petroleum xanthate; then add emulsifier; then add 15# white oil; keep stirring and heating during the preparation. The temperature is controlled between 30°C and 50°C; according to the rolling conditions, add 95% deionized water and keep stirring and heating, the heating temperature is controlled between 30°C and 50°C, and finally formulated into a certain concentration of emulsified liquid for rolling. From the first rolling pass to the finished product, the emulsio...

Abstract

A special lubricating liquid for rolling copper and copper alloy is prepared from 32# universal engine oil, 7# universal engine oil, petroleum sulfosodium, emulsifier and white oil. The deionized water is added some time according to rolling condition. The process for preparing the lubricating liquid includes mixing, agitating or diluting and heating in circulation node with heating temp of 30-50 deg.C.

Description

Technical field: [0001] The invention relates to the technical field of non-ferrous metal processing lubrication, and relates to a special lubricating liquid for rolling copper and copper alloys and a preparation method thereof. technical background: [0002] Domestically: There is no unified standard for the use of rolling lubricating fluid in copper processing enterprises across the country, and there is no ready-made lubricating fluid for selection. Due to the small demand for rolling lubricants, there are no domestic companies specializing in the production of lubricants, and there is only one emulsion blending company. Most copper processing companies make their own lubricants, which has unstable performance and has a negative impact on production and product quality. Greater impact. [0003] Abroad: Esso-Mobil is the main manufacturer specializing in the production of rolling oil. The company's oil products have good process characteristics and enjoy high prestige in...
