FIELD: casting production. SUBSTANCE: method involves reagent feeding to the lower layers of melted metal through the hole in the capacity lining under pressure of gas-carrier exceeding ferrostatic smelt pressure. Hole is closed after treatment finishing is carried out by mechanically after gas-carrier pressure relieve up to the value exceeding ferrostatic smelt pressure by 0.3 atm, not less. EFFECT: improved method of process. 2 cl, 1 dwg, 1 tbl
