Ivanenko V.F. Removal of Nonmetallic Inclusions by Filtering Nodular Iron Melt through Active Grain Filters
The article discusses the process of filtering nodular iron melt through active grain (lump) filters based on silicocalcium, limestone, fluorspar and pellets of ground Mgand REM-containing master alloy. Processes of influence of grain filter composition, filter grain diameter, nodular iron melt temperature on the size, shape and amount of nonmetallic inclusions (NMI) after filtration have been investigated. It was found that, apart from reduction of NMI quantity, filtration of liquid metal through active grain filters can have a graphitizing effect on nodular iron melt.
Key words: nodular iron, melt, active grain filters, liquid metal filtration, nonmetallic inclusions, graphitization.

Nuraliyev F.A. , Semyonov P.V., Petrov L.A. About the Metal Crystallization during Centrifugal Casting
The peculiarities of heat from the metal into a mold in the horizontal axis of rotation. Change in the intensity of heat by bathing the mold in a water bath, with jets of water supply on a rotating mold, the mold cooling spray nozzles water. We give examples of the pieces of cast iron rolls sheet rolling mills - for protection against heat molds poured cast iron used friable insulation or special paint antipenetration (Patent number 235 505), in the form of colored pieces of cylinder liners of diesel engines, pieces of rolls for the food industry of bronze. In the vertical axis of rotation - were cast in the mold lined with steel casing Books rail cars, in the form of a rod blank injection pump impellers and other parts of workpiece.
Keywords: pig iron, billet, forming rolls, mould.

Issues of solidification of hypoeutectic silumins in thin mold channels in casting with crystallization under pressure (CCP) are discussed. Dependencies of growth intensity of solidifying melt skin on the process parameters and thermalphysic parameters of materials used have been established.
Key words: silumins, melt, pressure, solidification, mold channel, skin.

Dementev V.B., Ovcharenko P.G., Leschev A.Yu. Method of Deep Alloying of Molded Steel Pieces During Casting on Consumable Patterns
In the work method of surface alloying of required area of cast section to a specified depth is treated. Method is carried out by insert of metal plates or needles, required composition for increase operating characteristics in polystyrene model with constant pitch. During model filling by fusion, alloyed layer with given depth is formed.
Key words: alloying, casting on consumable patterns, boronizing.

Zhenzhurist I.A., Buntin A.Y. Effect of Additions of Hydrosols of Aluminum and Silicon Oxides on Molding Sand Properties
Work is denote studying an influence of nanodispersed particles an hydrosol oxides silicon and aluminum, on the structurization clay and sandy. Explored action nanodispersed hydrosols, termoaktive clay and sandy on the process an precipitate particles of clay in the water ambience, as well as structurization modified nanosol an sandi-cley to compositions when shaping a material in process of drying. On changing an incrementation, toughness on the compression, fluidity, toughness is analyse dependency of modifying an sandy cley to compositions from the type an nanosol and sequence of their additive.
