FEEDING METHOD OF LUBRICATING OIL DURING PROCESS OF COLD ROLLING Russian patent published in 2009 - IPC B21B27/10 

FIELD: metallurgy.

SUBSTANCE: invention is provided for lubrication feeding while rolling of metal sheets made of different materials, allowing during the process of cold rolling different qualities. Method includes feeding of lubricating oil for emulsion feeding of mixed together lubricating oil and heated water to entering side of rolling mill during the process of cold rolling of steel plate. It is proposed storage of two or more types of lubricating oil with different compositions and, at least, one additive type in particular tanks, choose of one of mentioned stored lubricating oils or mixing of two or more types of lubricating oils, according to friction ratio between rolled metallic plate and roll die, blending, at least, of one chosen lubricating oil and, at least, of one chosen additive for receiving mixed oil and feeding of emulsion, containing those mixed oils, blended with heated water, to the rolling mill entering side. It is possible regulation of friction ratio ensured by change of emulsion conveying speed, its consumption or passing on emulsion of other composition feeding.

EFFECT: limits elimination for lubricating equipment, lubrication control system.
