WAYS OF PERFECTING THE TECHNOLOGY OF MAKING LARGE CASTINGS,
Abstract
A discussion is given of the progress made in non-Soviet countries in working refractory alloys and other metals with relatively low ductility, and considers the problems which must be solved for increasing Soviet production of large forgings. It is pointed out that forging productivity can be increased only by automation, mechanization and development of new technological processes for producing blanks. Scientific research and design organizations in the Soviet Union today are devoting their main efforts to development of programmed control systems applicable to traditional forging methods. It is felt that more energy should be devoted to development of progressive technology which fits into the requirements of complex mechanization and automation. Some of the steps to be taken in achieving this goal are discussed and recommendations are made for improving the workability of refractory metals by mechanical heat treatment. Improvements in ingot production are suggested. It is pointed out that the production of forging blanks by the most progressive methods will require high-speed hydraulic presses with a capacity of 20-30 thousand tons. (Author)
