Murokh A.F., Badryzlova М.Р., Aronovich D.A., Klenovich O.N., Khamidulova Z.S. Improvement of Casting Tightness by Using Impregnating and Metal-Filled Compositions
The article is dedicated to the modern sealing methods of porous castings using acrylic impregnating compositions. Sealing technologies of anaerobic and heat curable impregnating materials are considered. The most effective trademarks of commercial compositions are presented in this paper. The possibility to use metal-filled compositions for elimination of macrodefects and repair of castings surface is also shown.
Key words: acrylic antipores, impregnation technologies, defects, die casting, tightness.

Vogel W. Treatment of Primary Silicon Grains in Hypereutectic Alloys
Casting requirements become ever tougher, and, as a consequence, so do metallurgical requirements on alloys. For this reason, currently, ever more frequently they start to use alloys that used to have a very limited application, for example, cast hypereutectic Al alloys.

Nazaratin V.V., Nuraliyev F.A. High-Speed Pouring Modes for Large Steel Castings
The practice of using high-speed pouring modes in the production of large steel castings weighing up to 2001 and more is analyzed. A method of designing the gating system (GS) and a procedure of designing its basic elements for pouring molds allowing a mass rate of feeding liquid metal up to 1500 kg/s and higher have been proposed. For wide application of high-speed pouring modes, specifications and sketches for 10 types of refractory chamotte products with an inner diameter of 120 mm for GS of steel castings have been developed. Key words: steel casting, high-speed mode, gating system, pouring time, riser.
