Abstract
A method for rolling rolling stock, wherein a water-based cooling lubricant is applied to the rolling stock and/or to at least one roller which forms a roll gap, at least one water-soluble and tribologically active additive being added to the water-based cooling lubricant prior to application to the rolling stock and/or to the at least one roller.
Claims12
A method for rolling rolling stock (1), preferably for the cold-rolling of rolling stock (1), wherein a water-based cooling lubricant is applied to the rolling stock (1) and/or to at least one of the rolls (20, 22, 30, 32) forming the roll gap (200, 300),
- wherein at least one water-soluble, tribologically active additive is added to the water-based cooling lubricant before it is applied to the rolling stock and/or to the at least one roll, wherein, after application to the rolling stock (1) and/or to the roll (20, 22, 30, 32), the excess cooling lubricant is collected, whereupon the cooling lubricant is used again for application to the rolling stock (1) and/or to the roll (20, 22, 30, 32), wherein
- the excess cooling lubricant is subjected to ultrafine filtration after it has been applied but before it is reapplied.
A device for rolling rolling stock (1) in a roll gap (200, 300) formed by rolls (20, 22, 30, 32), wherein a water-based cooling lubricant is applied to the rolling stock (1) and/or to at least one of the rolls (20, 22, 30, 32) forming the roll gap, and wherein a water-soluble, tribologically active additive is added to the water-based cooling lubricant, wherein
- at least one filter device (8) is provided for the ultrafine filtration of the collected cooling lubricant.
