TH51484B - Method for supplying lubricant in cold extrusion - Google Patents

Abstract

The current invention DC60 provides a method of supplying cold rolling lubricants for stable rolling without thermal abrasion or sliding and achieving yield rates at High and improvement of the specific consumption of lubricant, that is, the method for dispensing Cold rolling lubricant for cold rolling back-to-back lubrication of sheet-metal by supplying a pre-determined emulsion lubricant containing mixtures. Of extrusion oil and water at the inlet side for extrusion from the nozzles. Method of supplying gas The lubrication in cold rolling is characterized by measurement or estimation of the pressure in Nozzle tube for lubrication (Pressure of the lubricating nozzle), pressure control Of the nozzles for lubrication of any extrusion unit. Where lubrication tends to become excessive When there is a pre-determined emulsion lubricant to 0.5 Mpa or more and while doing so, the supply of such lubricant to the inlet of the Such series by direct injection. The present invention provides a method of supplying cold rolling lubricants for a stable extrusion without thermal abrasion or sliding and achieving yield rates at High and improvement of the specific consumption of the lubricant, that is, the method for dispensing Cold-rolling lubricant for cold-rolled co-extrusion lubrication of sheet-metal by supplying a pre-determined emulsion lubricant containing mixtures. Of extrusion oil and water at the inlet side for extrusion from the nozzles. Method of supplying gas The lubrication in cold rolling is characterized by measurement or estimation of the pressure in Nozzle tube for lubrication (Pressure of the lubricating nozzle), pressure control Of the nozzles for lubrication of any extrusion unit. Where lubrication tends to become excessive When there is a pre-defined emulsion type lubricant to 0.5 Mpa or more and while doing so, the supply of such lubricant to the inlet of the Such series by direct injection.
