RATIONALIZATION OF PRODUCTION OF SHAPED INSERTS FOR ROTOR CASTING

The article deals with the rationalization of the production of shaped inserts for casting rotors. The theoretical part describes the characteristics of shaped inserts for rotor casting, die casting technology, analysis of the existing technology of production of shaped inserts. The main part of the article is focused on the proposed technological process of production, comparison of existing and proposed process. The article concludes with a technical and economic benefit of the proposed solution and evaluation of the work. Rationalization of production has its justification in the development of the company and thus improve competitiveness in the market. These interventions in production offer the possibility of using new technologies that are beneficial both from an economic point of view and to improve working conditions. The article focuses on the description of the existing technology, its evaluation and subsequent processing of a new technological process.

Electromagnetic Modification of Aluminium Ingots in Rotary Casting Machine

This article considers the problem of modifying the ingot structure by electromagnetic effects in the rotor casting machine. The principle of the electromagnetic modifier operation and the apparatus design are described. The results of physical modeling process of electro-magnetic modification of crystallizing ingot are presented.

Magnetodynamic Mixer-Batcher for Overheating and Pouring of Cast Iron

Magnetodynamic mixer-batcher is intended for adjustable inductive heating and controlled electromagnetic pouring of cast iron into crystallizers and moulds on automated casting lines, chill-mould casting machines, rotor casting machines. Also, mixer-batcher allows realizing the out-of-furnace treatment of liquid alloys. In comparison with conventional ladle pouring of grey cast iron, application of magnetodynamic mixer-batcher allows to reach more isotropic structure and properties on casting body, to increase 5-10% the mechanical properties of castings, and to refine both the metal matrix structure and dimensions of graphite inclusions. Moreover, using of magneto-dynamic mixers-batchers provides automation of pouring, economy of materials and energy re-sources, increasing productivity, and improvement of ecology.
