Cold rolling lubricating oil for cold machining of metal

Abstract

The invention discloses cold rolling lubricating oil for cold machining of a metal, which is characterized in that the cold rolling lubricating oil is prepared from the following raw materials in parts by weight: 40-60 parts of additive-free impeller oil, 10-25 parts of zinc stearate ester, 5-15 parts of tallow, 0.5-2.5 parts of phosphate, 1.0-12 parts of maleic acid / isonbutene copolymer potassium salt and 0.1-1.0 part of antioxidant. The cold rolling lubricating oil has the characteristic of good antifriction, and can prevent seizing, thereby meeting the requirement of large-deformation rolling; by using the cold rolling lubricating oil, the roller is effectively prevented; and the surface finish quality of a slab is improved, the cooling property is good, the stress influence on the slab and the roller is effectively controlled because of the rising of temperature, the temperatures of the slab and the roller are reduced, the service life of the roller is prolonged, the washing property is good, the slab and the roller can be fully cleaned, the pollution of iron powder on the slab and roller can be eliminated, the quality of the slab is effectively improved and the corrosion resistance is good.

Description

technical field [0001] The invention relates to a lubricating oil, in particular to a cold-rolling lubricating oil for metal cold processing, which is an indispensable chemical for metal cold processing. Background technique [0002] With the rapid development of the national economy and the improvement of people's living standards, the demand for aluminum and its products continues to increase, and the demand for aluminum cold rolling oil increases accordingly. It cannot meet the requirements of large deformation rolling process, especially the poor surface finish and low cooling performance of the plate. For example, the average oil consumption per 1 ton of aluminum profile rolled is about 15kg. The demand for cold rolling oil is huge. In terms of rolling oil, both the application process production and the oil technology level are relatively low. Contents of the invention [0003] The purpose of the present invention is to provide a cold rolling lubricating oil for met...
