Design and operation of a new roller quencher for rapidly cooling melts into glasses
We discuss the design and construction of a new roller quencher that is capable of cooling liquids at rates up to 1·8×106°C/s. The new roller quencher is based on refinements to our proven twin roller designs. This new generation of machines will have a number of advantages over the existing ones, including digital control of the speed of the rollers and gap adjustment, the ability to control the atmosphere over the resulting glass samples, ease of cleaning, and size. We also discuss the use of roller quenching at Coe College to form borate, and other glasses.
