The D51Y series vertical ring rolling machine developed by Duolek is an ideal solution for hot rolling and expanding processes of circular rough blanks. This equipment is primarily used for processing non-welded ring parts including bearings, flat welding flanges, high diameter flanges, and small thin-walled barrel components. It seamlessly integrates with the forging process after upsetting and punching operations.
- Incorporates mature technology with every detail carefully designed and rigorously inspected for reliable performance
- Features a ring expansion fixed rolling wheel system with high axial positioning accuracy
- Simplified mechanical processing of rolling wheel with reliable connection system
- Main components constructed from cast steel and high-quality alloy steel with proper heat treatment
- Welded steel plate construction for bed and base ensures good rigidity with lightweight design
- Comprehensive operational testing and precision inspection before delivery
