A solution for high-end tube producers DANIELI W+K (DWK) cold pilger mill 32- Q-C for zircaloy and stainless steel tubes and bars has successfully passed full scale load tests at the workshop in Buttrio, Italy, and is now under commissioning in the Nuclear Fuel Complex plant in Hyderabad, India. A subsequent order signed with the same customer last October confirmed DWK mills as a solution to the pressing requirements of this niche market. ball screw supported on both ends, and a water cooled servomotor); and a vibration-free mass balancing system designed to reduce foundation works and to minimise the overall capex of the project.

set up. The Q-Pilger approach avoids costly trial and error, which can have a high impact on budget and scheduling when developing new products. In a tough market characterised by over- capacity, DWK states that its mission is not only to supply new CPM mills to customers with the necessary resources for new investments, but also to help tube producers use existing mills more efficiently by installing technological packages specifically developed to revamp existing CPMs.

Tooling design using 2D and 3D FEA techniques allows simulation of the rolling process and estimation of the separating forces on the rolls and retaining load on the mandrel in advance. This is a crucial aspect for the closed loop mill design. In the Quarto CPM configuration, load cells can be used to monitor separating forces on-line during production, offering DWK the possibility to close the loop even during operation with a proper mill

The main advantages of the Quarto mill are a rigid mill stand design capable of resisting high separating forces; a continuous and precise shell feeding section with CNC machine solutions (profiled guide ways, a recirculating
