Title:

METHOD OF LUBRICANT SUPPLY IN COLD ROLLING

Document Type and Number:

WIPO Patent Application WO/2006/054777

Kind Code:

A1

Abstract:

A method of lubricant supply in cold rolling that while carrying out stable rolling free from the occurrence of heat scratch and slip, realizes high productivity and improvement to lubricating oil unit consumption. There is provided a method of lubricant supply in cold rolling, including performing of rolling lubrication in a cold tandem rolling of metal sheet by feeding one given type of emulsion lubricant consisting of a mixture of rolling oil and water through a nozzle at each rolling stand on its inlet side, characterized in that upon measuring or estimating of a pressure within lubrication nozzle piping (lubrication nozzle pressure), while effecting pressure control so as for the lubrication nozzle pressure of rolling stand at which a lubrication excess is likely to occur at least with the above given emulsion lubricant to be ≥ 0.5 MPa, the lubricant is directly jetted toward the roll bite inlet of the concerned stand to thereby attain lubricant supply.
