Ring rolling mill


Introduction :

Ring rolling mills are used where the diameter of the blanks needs to be increased in order to produce rings. For this the blanks are heated to forging temperature and their wall thickness reduced during radial ring rolling by a main roll and a mandrel roll. For radial-axial ring rolling, two axial rolls reduce the height of the blanks simultaneously.


Application :

Carbon steels

Low and high-alloy steels

Austenitic steels

Super alloys such as Inconel, Hastelloy, Waspaloy, Incoloy, Nimonic

NF metals such as titanium, aluminium and copper alloys
