Abstract
The invention concerns a tube release roll mill with four or more driven rolls, which in pairs form a pass opening. The diagonally positioned identically constructed rolls have an enlarged working surface width. A certain roll pair spacing is also provided, as well as an enlarged angle of attack of the rolls, which together result in the wall thickness of the tube bloom being more uniform, the development of fewer surface defects, and a quieter operation of the roll mill.
