3500MM RING MILL
H/280/V180-Ø3500 RING MILL
1. Ring Rolling Mill
The horizontal / vertical ring rolling mill is provided for rolling seamless rings at forging temperature.
2. Working Range
Outside Diameter of finished ring : 600 ~ 3500 mm
Height of finished of ring blank for : 00 ~ 750 mm
Mandrel diameter Ø220mm : min. 240mm
Height of ring blank : max. 1050mm
Ratio of wall thickness to height : max. approx. 3 : 1
Ring weight : max. approx. 8000 kg
The max. possible ring weight as well as the obtainable ratio "wall thickness
to height" is dependent on the cross section of the ring, the ring profile and
the ring material, its deformation resistance depending on temperature,
and on deformation speed.
