INSTALLATION FOR MAKING PELLETS BY CENTRIFUGAL MELT SPRAYING Russian patent published in 1995 - IPC

FIELD: metallic pellet production. SUBSTANCE: installation includes the spraying furnace 1 with the sealed melting apparatus 2, having a cover with the charging hatch 3 and a branch pipe for inlet of the metal conduit 4. The metal conduit 4 is in the form of a siphon, whose one end through the sealing gasket 5 is immersed into the liquid lock 6 of metal and whose other end through the centering body 7 with the sealing current-conductive gasket 8 is introduced into the cover of the pelletizing chamber 9. System of inlet of the metal conduit 4 into the spraying apparatus through the centering cone allows to achieve a necessary degree of axial alignment between the discharging hole of the metal conduit and an aperture sleeve and therefore to increase a yielding of spherical pellets of main fraction. Using of the liquid lock and the sealing gasket in the ends of the metal conduit, being heated by direct current, allows to insulate a volume of the palletizing chamber from an atmospheric air. EFFECT: enhanced efficiency of the installation. 2 cl, 1 dwg
