Title:
金属溶融物の製造方法及び装置
Document Type and Number:
Japanese Patent JP4656796
Kind Code:
B2
Abstract:
In a process for producing a metal melt by reducing metal-oxide-containing material in a fluidized-bed reactor by the fluidized-bed method and by subsequently melting down the reduced material in a melt-down gasifier, in the melt-down gasifier there is generated from carbon-containing material a reducing gas which is used for reducing the metal-oxide containing material by the fluidized-bed method. Both the reducing and the melting-down are effected under atmospheric excess pressure. For the purposes of transferring the reduced material from the fluidized-bed reactor into the melt-down gasifier in a simple manner, a lower pressure is set in an intermediate vessel situated above the melt-down gasifier than in fluidized-bed reactor, and the reduced material is allowed to flow, under relaxation, upwards from the fluidized-bed reactor into the intermediate vessel and conducted from the intermediate vessel via a sluice system into the melt-down gasifier while being pressurized.
