High-speed casting of metallic foils by the double-roller quenching technique
Journal of Materials Science, 1982The ability to produce continuous metallic foils by double-roller quenching with a “mechanically-soft” system has been demonstrated. Significant process variables influencing foil dimensions and microstructures were determined for tin and Al-12 wt% Si foils. The foil formation process is controlled by both fluid and heat flow.

Numerical simulation for double-roller rolling process with deep-cylinder ring
AIP Conference Proceedings, 2013Deep-cylinder rings, as the key mechanical parts of heavy energy equipment, have wide application in nuclear reaction pressure vessels, oil hydrogenation reactors and coal liquefaction devices. Double-roller rolling (DRR) is a new rotary plastic forming technology for deep-cylinder ring manufacturing, which has the advantageous of low energy and ...

Cam mechanisms based on a double roller translating follower of negative radius
Mechanism and Machine Theory, 2016Abstract Constant-breadth cam mechanisms are characterized by the fact that the closure of the cam-follower contact is guaranteed thanks to the geometry and, therefore, auxiliary elements as springs are not necessary. On the other hand, cam mechanisms with a negative radius roller follower allow designing simple machines exerting remarkably high ...

Thin strip casting at Thyssen Stahl, using single or double roller
Revue de Métallurgie, 1990Two different routes for producing the strips are being tried by Thyssen Stahl : a single-roller machine for thicknesses of up to 0.3 mm is in use in Duisburg ; and a double-roller machine for strip in thicknesses between 0.3 mm and 1.0 mm is being operated jointly with the University of Aachen, in Aachen.The single-roller machine operates according to

DESIGN AND ANALYSIS OF CAM MECHANISM WITH TRANSLATING FOLLOWER HAVING DOUBLE ROLLERS
Transactions of the Canadian Society for Mechanical Engineering, 2015The pressure angle is one of the primary considerations in designing a cam mechanism since an inappropriate angle may cause excessive sliding loads on the follower. This paper presents a simple yet straightforward method for the design and analysis of a cam mechanism with a translating follower having double rollers.

Numerical Simulation Research on a New Spinning Process: Double-Roller Clamping Spinning Process
International Journal of Material Forming, 2010Thin-wall rotary parts with complex flange geometry have been widely used in many equipments, especially industrial fans and blowers. Conventional stamping and welding methods for those parts have some limitations such as low manufacturability, poor quality and low utilization ratio of material. Thus in this paper, a new spinning process, double-roller
