DEVICE AND METHOD FOR GASSING AREAS IN A REDUCTION REACTOR SHAFT

摘要

Device comprises a reduction reactor shaft (1), many reduction gas inlet lines which end in the interior of the reduction reactor shaft for introducing the reduction gas into the interior of the reduction reactor shaft, and a reduction gas channel body (11) which passes through the interior of the reduction reactor shaft for distribution of reduction gas into the interior of the reduction reactor shaft. An independent claim is also included for producing metal sponge or pig iron from metal oxide-containing material in piece form using a reduction gas, comprising introducing a first portion of the reduction gas into the bed by many reduction gas inlet lines which end in the interior of the reduction reactor shaft, and distributing a second portion of the reduction gas into the bed by reduction gas channel body which passes through the interior of the reduction reactor shaft.
