FINEX技术 ,是在COREX技术基础上进一步发展起来的新工艺 ,前者使用块矿、球团 ,后者全部使用粉矿。它们的主流程为 :COREX由熔化气化炉和还原竖炉两部分构成 ,块矿、球团矿通过炉顶料仓装入还原竖炉 ,被逆向上升的煤气还原成海绵铁 ,再经螺旋卸料器输送到熔化气化炉中。熔化气
FINEX technology is a new process developed on the basis of COREX technology. The former uses lump ore and pellets, while the latter uses powder ore all. Their main processes are: COREX is composed of melting gasifier and reduction shaft furnace. The lump ore and pellets are charged into the reduction shaft furnace through the top silo, reduced by reverse reverse gas into sponge iron, Unloading feeder delivered to the melting gasifier. Melting gas
