Mass production of composite castings

Regularities have been studied for forming bimetallic castings like bodies of rotation which have developed plane surfaces and spiral shapes. As a result, the engineering processes and equipment have been developed for their mass production. The processes provides a way of cutting high-alloyed alloys down to 70 %, of rising bimetallic casting service life by 1.5-4.5 times and output of wares hardening productivity by 6-8 times, of using available burden materials and ferroalloys. The engineering processes and equipment developed have been successfully introduced at 15 plants to a great technical and economical effects.
