“Stand-support sintering”, that is supporting the load of the sinter cake with bars or
plates attached to pallets, has been developed and applied practically to the sintering
machines in Kimitsu works, Nippon Steel. The stands start to support the load of the sinter
cake just after the top layer is melted and starts to solidify. Shrinkage is stopped
and the gas flow rate is increased when the stands start to support the load of the
sinter cake. It was found that sintering time was shortened and productivity was improved in
actual sintering machines.
