PROCESSO PARA REDUCAO EM BATELADA DE UM OXIDO DE METAL PARA METAL ESPONJA |
摘要 |
<p>A process for the direct gaseous reduction of iron ore to sponge iron wherein the sponge iron is cooled with a carboncontaining cooling gas by a dual temperature procedure that increases transfer of carbon from the cooling gas to the sponge iron and thereby permits the production of a product having a combination of relatively low or moderate metallization and relatively high potential metallization. Increased productivity of the direct reduction plant and of the overall integrated steel plant are achieved.</p> |
