Gasified models of spherical PROFIT

摘要

The invention relates to a foundry, particularly to exothermic gas models arrived for the production of steel and cast iron machine-cast pieces (castings). Gasifiable spherical model of profit made from foam and includes a cylindrical portion and hemispherical interconnected by the mating surface, wherein the seat installed in it an insert formed as a packet of the exothermic mixture is disposed in the cylindrical portion coaxially adjustment model. The insert may be formed as a sleeve or filling of the exothermic mixture. Proposed gasified profit model ensures high efficiency of the profit, to create a low-waste technology for producing high quality castings.
