The Phase II program has been conducted by a team of engineers from Westinghouse Electric Corporation and Armco, Inc., with the objective of providing a suitably sized experimental planar flow casting machine, and using it to perform casting trials to address the above technical uncertainties for cast thicknesses and speeds representative of industrial production, and with sufficient duration to diminish thermal transient effects. A nominally 7 ft. diameter water-cooled copper wheel planar flow casting system has been designed, fabricated and installed in a dedicated 15,000 sq. ft. foundry facility are Armco Inc., Middletown, Ohio. This system is capable of casting 3 in. wide strip and operating at surface speeds up to 25 ft/sec. Additionally, the facility also contains a 16 in. diameter water-cooled wheel with interchangeable casting substrates of different materials. This small wheel facility has been adapted to utilize the melt overflow process for casting of 3 in. wide strip. These casting facilities are supported by a 500 lb. induction melting furnace and necessary liquid steel handling equipment. Adequate techniques have been developed for transportation and filtering of liquid steel without undue temperature loss. Good control of the planar flow casting process was not achieved during this program, however given such control and the adoption of clean steel practices, the inference is that the process will be capable of producing strip which is readily cold-rollable in the as-cast condition. After cold rolling and annealing, such material should have useful mechanical properties. 8 refs., 112 figs., 10 tabs.
