Rolling Mill Machine Concept By Basic - pure-line.be

Rolling Mill Machine Concept By Basic. May 30 2013 Basic concept of the rolling The arc of contact between the rolls and the metal is a part of a circle The coefficient of friction is constant in theory but in reality it varies along the arc of contact The metal is considered to deform plastically during rolling.

Fundamentals of Roll Cooling and Control of Flatness at ...

In the process of Rolling the most significant aspect is the generation of heat through friction and deformation in the roll bite and in a typical Cold Tandem Mill, work roll temperatures normally fall in the range of 55oC – 70oC with strip recoil temperatures and inter-stand strip temperature rarely exceeding 160 oC depending on product.

Basics of Rolling and Rolling Mills – IspatGuru

Fig 4 Roll configurations in rolling mills. Two-high mill roll configuration – This is the most commonly used rolling mill configuration. In this configuration, there are two horizontally mounted rolls. The rolling mill motor drives either both rolls (top and bottom) or only one roll (normally the bottom roll) with the top roll rotating due to the friction between the roll and the work piece.

S6-high cold rolling mill - andritz.cn

A special feature of Sundwig S6-high rolling mills are the side-supported work rolls. The patented Sundwig S6-high side support stabilizes the work rolls in this type of mill stand using mechanical, hydraulic lateral support equipment, thus preventing lateral excursion of these rolls. The diameter of the S6-high work rolls is only approximately 30% of the diameter of the 4-high work rolls and ...
