Leushin I.O., Chistyakov D.G. Analysis of the processes of carbide-formation in the surface layer of castings glass-molds
The operation of details of glass molds is carry out in the complex thermo-mechanical conditions. One of the conditions of reliable work of the details of this type is the creation of a fine-grained structure in the areas of contact with molten glass. The creation of such a structure is accompanied by the formation of a large number ofcementite and cementite ledeburite in the surface layer. Control over the processes graphitization and carbide-formation in the surface layer of the workpiece will allow to control the process of the creation of casting with the required structure.
Keywords:Cast iron, glass-mold, modifier, metal refrigerator, chill, cementite, ledeburite.

Key words:Casting, pressure, steel, dies, technology, castings.

Pivavarchyk A.A., Michalzov .. Effect of dividing methods of applying coatings to a thickness of cutting the separation layer of aluminum casting alloys under pressure
The results of studies to determine the thickness of the lubricant layer separation, depending on how they are applied to the surface of the casting equipment.
Key words:Release coating, die casting, aluminum alloys, thickness gauge, cutting the spacer layer.

Gruzman V.M., Musinov M.V., Burdakov K.A. Study of Regime of Binder Settling on Sand Grains in Fluidized Bed
Proposed is a method of comparative determination of the critical sand fluidization rate in a molding sand preparation plant. Existence of an optimal fluidization rate is shown. Tendency towards lower sand strength during additional, after binder settling, boiling has been established.
Key words:Binder, sand, boiling bed, critical fluidization rate.

Guriya I.M., Lyutyi R.V., Keush D.V., Smolskaya V.S. Core Sands with a Binder Based on Orthophosphoric Acid and Alkaline Metal Salts
The article presents the results of the development of new core mixtures based on previously unexplored binding system of phosphoric acid and inorganic salts of alkali metals. In the composition of the mixtures are used sodium tripolyphosphate, sodium chloride and potassium chloride, that are react with phosphoric acid. Established that binders in core mixtures, which provide higher total and surface strength, are potassium and sodium phosphates that are formed directly in the mixture at thermal strengthening of its components. Cores provide produce quality castings in iron and steel.
Key words:Phosphoric acid, strength, binding composition, core mixture, sodium tripolyphosphate, sodium chloride, potassium chloride.
