Chumanov I.V. , Porsev M.A. About the influence vanadium for the grain of molten steel 110G13
The results of disquisitions by observation of the influence vanadium for the value of the grain of molten steel 110G13L describe in the work. Show that the availability in steel 0,15 percent of V already grates substantially relevant of the structure of austenite. The mechanism of the influence of additives V for the value of the grain and some features of steel examines in short. Reducing some arguments that telling about the affirmative influence of additives V on mechanical qualities of molten steel 110G13L.
Key words: value of the grane, vanadium, casting, prime cost

The article reports about work by the Chair "Computer-aided design and foundry technology" of MATI as applied to the production of critical castings, such as blades for gas turbines and thin-walled large-size missile bodies.
Key words: gating system, blade, body, chill mold, chill, core, gassing capacity crumblability, moisture.

Stulov V.V., Sevastyanov A.M. Processes of Casting Aluminum Alloy in a Lined Mold in Making Hollow Castings
Completed casting aluminum lined with uncooled form centered on the uncooled and cooled heat pipe. Established that the cooling time of hollow casting is reduced by more than 3 times in the presence of cooling pipes. Thus, increasing more than twice the rate of crystallization of the metal.
Key words: lined form, heat pipe, aluminum, cooling, water.

Shishkovsky I.V. Outlooks for Rapid Prototyping to Make Patterns and Foundry Molds
A review of modern methods of rapid prototyping, and procedures that allow implementing those technologies in creating patterns and foundry molds is presented.
Key words: prototype, rapid instrumentation, polymer, shell mold, spray metal casting, vulcanization casting, gypsum mold.

Koltygin A.V., Gorbuzova I.V., Abramova T.I., Bazhenov V.Y. Properties of Z-cast Material Used for Mold Making by the Method of 3D Printing
Studied technological properties of Z-cast molding sand designed for mold and casting manufacture by the method of 3D printing, as well as results of sand X-ray phase analysis are presented. Dependence of strength characteristics of Z-cast sand on the impregnation material and heat treatment modes has been revealed. Effect of various inoculants on the strength and technological properties of sand have been established, and experimental compounds virtually not inferior to the proprietary material Z-cast by its technological properties have been obtained.
Key words: 3D printing, Z-cast sand, 3D printer, foundry mold, technological properties of sand, inoculant, import-replacing counterpart, InkJet.

Tsynovnikova Y.P., Koltygin A.V., Blishun S.A. Peculiarities of Industrial Application of Molds and Cores Made by the Method of 3D Printing on an S-15 Plant
Effect of storage conditions and duration on the technological properties of molds made by the method of 3D printing is discussed. Dependencies of gas permeability values of sand on the time of contact with hot metal have been obtained. Analysis of the data obtained shows a discrepancy between the values of technological properties of sands conventionally made under normal conditions and the actual values during metal pouring and casting cooling.
Key words: 3D printing, cold-hardening sands, gas permeability, thermal destruction of binder.
