通过一个闭锁式的料斗装置,把块矿、烧结矿、球团矿,或者这些原料的混和料,加到一个还原炉中。在炉中,它们由逆向流动的还原气体还原成含铁约93%的金属化直接还原铁(DRI)。排料螺旋输送机把直接还原铁(DRI)从还原炉送入熔化气化炉中。在熔化气化炉中进行最终的还原和熔炼,并发生其他的所有冶金反应(见图1),然后象传统的高炉炼铁一样 A lump hopper, sinter, pellet, or mixture of these raw materials is added to a reduction furnace through a lock-up hopper unit. In the furnace, they are reduced by the countercurrent reducing gas to about 93% metallized DRI. Dumping screw conveyors direct reduced iron (DRI) from the reduction furnace into the melting gasifier. The final reduction and melting takes place in a melter-gasifier and all other metallurgical reactions take place (see Figure 1), then the same as in conventional blast furnace ironmaking
