Heat and Chemical Heat Treatment in Fluidized and Vibrofluidized Beds

Abstract

Research and development work on the application of a fluidized bed for thermal treatment began in the USSR in 1957 when it was first suggested as a hardening medium. Since then, fluidized bed technology has been widely used in various branches of metallurgy and machine building. At present, quite a number of heat and chemical heat treatment techniques in a fluidized bed have been developed and realized in industrial conditions. The authors discuss some of these methods in this article.
