A method of operating a two-stand reversing rolling mill to improve mill productivity and rolled product yield, said mill having two spaced-apart pairs of vertically disposed work rolls with an adjustable roll gap therebetween, comprising passing an elongated strip in a first pass through the two mill roll stands from a pay-off reel disposed upstream of a first tension.
Danieli three-roll cross rolling mill in quick operation at Vallourec, Rath, Germany After just two months of performance testing, Vallourec Deutschland released mill acceptance certification Excellent performances achieved right from the beginning by Vallourec Deutschland VAD operating the new Danieli cross-rolling mill.
How the Three Roll Mill Works. The material to be milled is placed between the feed and center rolls. Each adjacent roll rotates at progressively higher speeds. For example the feed roll may rotate at 30 rpm, the center roll at 90 rpm and the apron roll at 270 rpm. Material is transferred from the center roll to the apron roll by adhesion.
