Abstract

The invention relates to a cold rolling and rough rolling lubricating agent for a copper and copper alloy sheet strip. 32# oil for a total-loss system is used as base oil and is matched with various composite additives including an anti-wear agent, an oiliness agent, an anti-oxidant and anti-corrosive additive, a metal deactivator, an anti-foaming agent, a dispersing agent and the like. The lubricating agent has the characteristics of relatively high viscosity, thick and firm oil film, high allowable pressure, good cooling performance and flowability and strong pollution, emulsion and foam resistance so as to be suitable for being used under the working conditions of hard rolled pieces and high rolling pressure.

Description

technical field [0001] The invention belongs to the field of rough rolling lubricants for cold rolling of copper and copper alloy plates and strips. Background technique [0002] Lubricants for cold-rolling copper and copper alloy sheets and strips require good rolling performance so that the maximum reduction can be obtained with the minimum downforce; at the same time, they must also have good oxidation resistance, corrosion resistance and Anti-foaming properties, especially strong surface pollution resistance, that is, there will be no oil stains on the surface of the product, especially during the annealing process, there will be no carbon spots, sulfur spots and water spots. [0003] When cold rolling copper and copper alloy sheets and strips, it is usually divided into rough rolling (also known as intermediate rolling) and finish rolling. Roughing mills are often aimed at ensuring maximum reduction rather than precise dimensions and good surface finish. During this s...
