FIELD: metallurgy, particularly, designs of capsules filled with low-melting and rapidly oxidizable alloying components, or additives with melting point below melt temperature. SUBSTANCE: capsule shell is made of metal - base of melt or from metals included into composition of metal melt. Capsule has weight correcting its total density to value exceeding density of metal melt by 0.5-1.0 g/cu.cm. Walls of capsule shell are made with thickness ensuring complete melting of capsule in metal melt and may have axial, radial and tangential holes of 1.0-3.0 mm in diameter. EFFECT: spontaneous immersion of capsule into melt, uniform distribution of alloying components or additives and their complete melting or dissociation. 2 cl, 1 dwg |
