The method of obtaining the castings in vacuumized molds with gasified consumable pattern includes the arrangement in the container with friable refractory material of cellular polystyrene pattern, its degassing, further gravitational filling with the upper bringing of metal, cooling and removal of castings after their hardening, moreover the gravitational filling of the mold is achieved through multistage pouring gate system at the rate of lifting of the metal in the mold of 5.0-10.0 cm/s and temperature of 1560-1620 DEGREE C, with subsequent annealing of the obtained casting.
