ANNULAR SINTERING MACHINE FOR AGGLOMERATION FOR PRESSURE SINTERING OF ORE MATERIALS Russian patent published in 1994 - IPC

FIELD: metallurgy, namely apparatus for pressure sintering. SUBSTANCE: machine has two independently and periodically rotating platforms and plates, supporting sintering cups. The plate, designed for discharging, charging and igniting, it is provided by respective devices. The platform is designed for sintering an agglomerate with simultaneous sublimation of non-ferrous metal additives from a layer of the charge, and it is provided by clamping hoods for feeding compressed air and for sealing cups. The sintering cups are arranged on movable cars, and its possible to replace them from platform onto the plate and vice versa with the aid of a pusher. The charge is being ignited with use of a pressure, created by a special clamping device. The platform for sintering is provided by a separate vacuum chamber with autonomous gas scrubber, placed in a position of replacing the cups. The remaining position are joined by a common vacuum chamber with the main gas scrubber. Such structure allows (at a final stage of the process) to remote non-ferrous metal additives from the layer and to collect them in the containing materials with admixture of non-ferrous metals for obtaining separate ferrum containing product and non-ferrous containing product. EFFECT: enhanced efficiency, good labor conditions and ecology. 1 cl, 3 dwg
