METHOD AND MACHINE FOR POROUS METAL STRIP PRODUCTION Russian patent published in 2011 - IPC B22D11/06 B22D11/108 

FIELD: process engineering.

SUBSTANCE: invention relates to continuous metal casting. Proposed device comprises two-roll casting machine, performing agent feed assembly 9 arranged between crystalliser rolls 3, 4 in plane parallel with axes of said rolls, metal pipeline for lateral feed of fluid metal 5 to said rolls that includes chute 7 and intake bin 8 with walls 11, 12, 13 and 14 that stay in contact with crystalliser roll surface. Refractory web 7 is arranged at the center of chute 7 on intake bon side. Proposed method comprises feeding metal 5 into intake bin 8 and feeding powder-forming material in zone wherein crystalliser rolls 3, 4 entrap metal 18. Fluid metal 5 is fed into said zone 18 in two flows on both sides of powder-forming material intake assembly 9. Strip is drawn in top or bottom direction. Air, inert gas, powder strip or wire may be used as powder-forming substance.

EFFECT: continuously-cast three-layer metal strip with porous core.
