METHOD FOR PRODUCING SMALL-SIZE CAST PIECES OF HIGH-ACTIVE METALS AND ALLOYS AND PLANT FOR PERFORMING THE SAME Russian patent published in 2008 - IPC B22D21/02 F27B17/00 

FIELD: manufacture of dentures, jewelry, small-size articles.

SUBSTANCE: apparatus includes melting and pouring chamber where non-consumable electrode and crucible of graphite are arranged. Inner surface of crucible is covered with refractory tungsten non-interacting with melt. Apparatus for tilting crucible includes carcass having two mutually parallel vertical grooves. In mutually opposite grooves rollers are arranged with possibility of limited motion. Said rollers are secured to ends of levers through hinges joined with crucible. Carcass includes movable support for crucible secured to wall of carcass. Said support may be moved in horizontal plane. In order to set designed gap, crucible and apparatus for tilting it are moved upwards till contact of billet with end of electrode; then movable support of crucible is introduced and crucible is moved downwards till support. After melting billet said support is withdrawn. Crucible falls down and tilts along path providing motion of point of crucible inner surface at side of draining mostly spaced from axis of crucible in tilting plane along vertical line.

EFFECT: less consumption of power, improved quality of cast products, shortened time period for manufacturing cast products.
