Problems solved by technology

In addition, during the rolling process, with the continuous renewal of the plastic deformation and surface of the rolled piece, a large amount of aluminum powder (or its oxide) will be produced, resulting in the accumulation of aluminum powder in the rolling emulsion, which affects the rolling process. Lubrication condition and surface quality of rolled piece
[0004] The generation of oil sludge makes the rolling mill dirty, difficult to keep clean, and even affects rolling (such as...

Abstract

The invention relates to a combined emulsifier for aluminum hot rolling oil. The combined emulsifier comprises fatty alcohol polyoxyethylene phosphonate and polyoxyethylene ether fatty amine. The combined emulsifier is capable of emulsifying oil-in-water drops with stable particle sizes and providing a stable lubrication effect when applied to the aluminum hot rolling oil; the rolling oil can be endowed with excellent mixed oil resistance and aluminum powder dispersing performance, aluminum powder can be dispersed and concentrated into an oil phase of the surface and easily removed through the operations, such as skimming, the cleanness of an emulsion is maintained, and good performance of the emulsion is ensured; and the additive amount of oleic acid can be reduced, breeding of microorganisms is inhibited, oily sludge in the rolling process is reduced, and the service life of the emulsion is effectively prolonged.

Description

technical field [0001] The invention belongs to the field of metal thermal processing, and in particular relates to a combined emulsifier, an aluminum hot rolling rolling oil containing the same, and uses thereof. Background technique [0002] Aluminum hot rolling rolling oil is used for lubrication of hot rolling process of pure aluminum or aluminum alloy. Oleic acid and triethanolamine components are basically present in existing aluminum hot rolling rolling oils, and the two undergo a neutralization reaction under normal conditions to generate triethanolamine oleic acid soap (soap base). In general, oleic acid is preferentially adsorbed on the surface of the rolling stock and roll, and metal soap is formed during the rolling process. The so-called metal soap generally refers to the product of the reaction between metal ions and fatty acids, including aluminum soap, iron soap, magnesium soap, etc. The metal ions generally come from the rolling process (alloy) or foreign ...
