Technological line for production of activated powders by hydro-vacuum dispersion of liquid metals

Abstract

This article is a short scientific communication devoted to substantiation of expediency of industrial implementation and further development of our innovative unified development of hydro-vacuum dispersion of metallic melts. Here the basic principles of the dispersing line functioning are given and its advantages over traditional technologies are shown.

Hydrated aluminum powder for direct alloying of steel and alloys - challenges of the future

“…Perspectives for development Based on the above analysis, we concluded that there is a new possibility of improving the technology of direct alloying of steel and alloys, which is associated with the prospect of using as an active reducing agent obtained specifically for this purpose hydrogenated aluminum powder AlH 3 (H 1-5%). We were the first to obtain such a powder as a by-product of hydro-vacuum dispersion of liquid aluminum No 193 superheated at 150 o C. The observed effect was achieved by operating our hydro-vacuum dispersion unit [25] in the mode of generating a high-frequency cavitation-wave field [26] and initiating sonochemical hydrogenation reactions. According to the study of [27], the general sonochemical hydrogenation reaction of metal powder particles can be written as follows:…”
