Method for Lubricating Milling Material

Abstract

Disclosed is a method for rolling milling material, especially for hot wide-strip rolling in a finishing train or a continuous casting and rolling plant, in which a lubricant is applied directly to the surface of the working rollers or indirectly to the surface of the support rollers, the lubricant then being transferred to the surface of the working rollers, before the milling material is fed into the roller gap of a roll stand. A highly adhesive lubricant film forms on the surface of the working roller, said lubricant film resulting in a reduction of friction in the roller gap as an intermediate layer between the roller and the milling material. According to the inventive method, the lubricant is applied along the entire length of the milling material such that the lubricating effect comes into play along the entire length of the milling material.

1 . Method for the rolling of rolling stock, especially for the rolling of hot-rolled wide strip in a finishing train or a continuous casting installation, in which a lubricant is applied directly to the surface of the work rolls or indirectly to the surface of the backup rolls and is then transferred to the surface of the work rolls, before the rolling stock enters the roll gap of a rolling stand, wherein a strongly adherent lubricant film forms on the surface of the work rolls and leads to reduction of friction in the roll gap as an intermediate layer between the roll and the rolling stock, wherein the lubricant is applied over the entire length of the rolling stock, and therefore the lubricating effect acts over the entire length of the rolling stock. 
     
     
         2 . Method in accordance with  claim 1 , wherein a lubrication system that feeds lubricant from a reservoir to the work rolls or backup rolls through lines and nozzles is turned on 5-15 seconds before the rolling stock enters the rolling stand. 
     
     
         3 . Method in accordance with  claim 1 , wherein the lubricant is applied in the second stand and in each subsequent stand. 
     
     
         4 . Method in accordance with  claim 1 , wherein the lubricant is applied in the third stand and in each subsequent stand. 
     
     
         5 . Method in accordance with  claim 1 , wherein the lubricant is applied in the second stand and in each desired subsequent stand. 
     
     
         6 . Method in accordance with  claim 1 , wherein the lubricant is applied in the third stand and in each desired subsequent stand.
