SATURATION DYNAMICS OF ALUMINUM ALLOYS WITH HYDROGEN

Текст статьи не публикуется в открытом доступе в соответствии с политикой журнала.This work presents research results on the dynamics of the saturation of aluminum and its alloys with hydrogen in a flow chart for preparing melts in the manufacture of flat-shaped ingots at UC RUSAL. It is demonstrated that one of the main sources of the saturation of an aluminum melt with hydrogen is its interaction with atmospheric moisture during open metal pouring in the course of its transportation from an electrolyzer to a mixer. According to the results of the conducted works, new technical solutions have been proposed whose introduction will ensure, in the long term, a considerable decrease in hydrogen content in aluminum ingots and low-alloyed aluminum alloys

Study of change in the scm's strength properties depending on the aqueous-clay suspension's concentration and muscovite's amount in its composition

Текст статьи не публикуется в открытом доступе в соответствии с политикой журнала.This article represents the results of the study of change in aqueous clay suspensions' (ACS) electrostatic properties depending on muscovite's concentration in their composition. The influence of ACS' concentration and muscovite's varied amounts in the composition of mechanically activated bentonite clay (Chernogorskoe field) used as a coupling agent in molding sand mixtures for steel and cast ironcasting, on the mixture's strength properties has been studied. The increase in the sand-clay mixture's (SCM) strengthproperties and gas permeability depending on the ACS's and muscovite's concentration has been establishe

CONFORM INSTALLATION STRUCTURAL ELEMENTS DESIGN METHODS

Текст статьи не публикуется в открытом доступе в соответствии с политикой журнала.The technical features in manufacturing press non-ferrous metal articles have been considered via the Conform continuous pressing. Based on an analysis of different types of press equipment, the absence of a connection between the system for fastening the two-part container fixed part (the shoe) and the working wheel shaft has been revealed as a shortcoming specific to many Conform installations. This does not allow observation of a controlled gap between the shoe and the groove bottom during the operation of the installation, which, in turn, breaks the stable feed of the bar billet into the die. The purpose of this operation is to develop a system for fastening the shoe that ensures the stable continuous metal extrusion process. Meanwhile, the task has been set of creating a tough and strong connection between the shoe and the working wheel shaft with the levers and drafts system that reduces the load of the bearings in the housing posts in which the wheel shaft rotates. As a result, the original technical solution of the Conform installation press unit has been developed. The practical use of the design presented in this work will open up new possibilities for manufacturing pressed metal non-ferrous metal products with a permanently high level of properties
