DEVICE FOR OUT-OF-FURNACE TREATMENT OF MELTS Russian patent published in 1995 - IPC

Abstract RU 2034041 C1

FIELD: metallurgy. SUBSTANCE: vacuum-chamber 2 has duct 3 vertically oriented to the receptacle for melt 1 to be treated. Duct 3 has a cut angled to the vertical axis at 45-70 degrees. Duct 3 is spaced from the receptacle wall at a distance equal to 0.25-0.40 of the length of either the main axis of the receptacle or its diameter. The duct cut is directed towards the receptacle center so that the angle between planes "a" and "b" ranges from 20 to 45 degrees where in plane "a" is drawn through the axis and minor generatrix of the duct and plane "b" is drawn through vertical axes of the duct and receptacle. EFFECT: enhanced quality of treatment. 2 dwg
