A kind of cold rolling extremely thin plate rolling oil composition

Abstract

The invention discloses a novel cold rolling extreme thin plate rolling oil composition. Synthesized ester and an alkylphenol epoxypropane compound are compounded to be used as an oily agent and can form a layer of quite dense protective film on the surface of metal to form favorable annealing detergency and heat stability. A nonionic compounded emulsifying agent can increase the diameter of the elaioplast of emulsion and shows better lubricity by matching with the interaction of a metal passivator, a sulfur-containing extreme pressure antiwear agent, and the like.

Description

technical field [0001] The invention belongs to the lubricating composition for metal processing technology, in particular to a cold-rolled ultra-thin plate rolling oil composition Background technique [0002] With the increasing demand for cold-rolled sheets in the automotive industry and household appliances, the requirements for the surface quality of cold-rolled sheets are getting higher and higher, and the rapid development of cold-rolled equipment and related technologies has led to the current high-speed production of cold-rolled sheets. and large-scale production. These five-roll rolling equipment and four-roll and six-roll equipment put forward stricter requirements on the lubricity of rolling oil, mill cleanliness, annealing cleanliness, cycle stability, and the disposability of waste rolling oil. At present, most of the domestic market is occupied by foreign brands. Many domestic enterprises and scientific research institutes have conducted research on this typ...

AI Technical Summary

Problems solved by technology

The rolling oil has good lubricity, but the rolling cleanliness is poor, and it cannot meet the requirement of bright annealing without degreasing treatment

The rolling oil has general lubricity and rolling cleanliness, and also cannot meet the requirement of bright annealing without degreasing treatment.

In short, the rolling oil based on grease is suitable for high-load and high-speed rolling. The most notable feature is its good lubricating performance. The existing problems are: first, the cleanliness of the rolling mill is poor, and a
