Аннотация: A current trend in nowadays metallurgy is to create combined technologies that cover several metallurgical treatment procedures or various operations performed on a single device dedicated to manufacturing required products and thus ensuring the manufacture of competitive products at minimal production costs. The forms in which the technological operations in metallurgical production are combined may vary. Most effective is the combination of casting and plastic metal working processes. However, during the crystallization of molten metal in an annular groove of the disc and subsequent pressing, a considerable amount of heat is generated, and part of it shall be removed to establish the isothermal conditions while carrying out the continuous casting and pressing process. Otherwise, unstable temperature in the pressed articles exiting a die channel may lead to mechanical properties' dispersion and the distortion of their geometry in length as well as at cross section of the pressed articles, thereby lowering the products' quality. It should be noted that the pressed article is destroyed when a temperature similar to the melting temperature of the pressed metal is achieved, which shall be considered as an ultimate defect. Moreover, increased pressing temperature decreases the strength of the tools, which leads to their premature failure. One of effective ways to solve this problem is forced cooling of both the pressing tool and metal section. This paper presents various technical solutions aimed at solving this problem. © 2006-2018 Asian Research Publishing Network (ARPN).
