SLRN process - Metso Outotec

In the standard SL/RN process, iron ore, coal, and dolomite or limestone as desulfurizing agent are charged into a rotary kiln and heated up by a countercurrent gas flow. Heat is generated by the controlled combustion of volatiles from the coal and surplus CO from the charge. The reduction of iron oxides in the solid state is achieved at temperatures between 920°C and 1100°C.

Talk:HIsarna ironmaking process - Wikipedia

The original goal was to produce direct reduced iron (in solid state). The SLRN Process : In 1965 the very first DRI developed was the Outokumpu Process by a consortium including STELCO of Canada, Lurgi, Republic Steel (USA) and National Lead, which caused the process to also be commonly known as SLRN. This process adapted the conventional limestone-to-lime converting kiln into an iron ore and coal fines iron reduction kiln which produced sponge iron

DRI production International Iron Metallics Association

The Midrex® and Energiron gas-based processes use predominantly iron ore pellets as feedstock, but sometimes with inclusion of lump ore in the furnace charge. The Finmet / Finored gas-based process utilizes iron ore fines as feedstock. The SLRN coal-based rotary kiln process uses lump ore and, increasingly, pellets as feedstock. There are variants of these processes which are described on the

Sponge Iron - an overview ScienceDirect Topics

The process involves heating the naturally occurring iron oxide in the presence of carbon, which produces “ sponge iron.” In this process, the oxygen is removed without melting the ore. Iron oxide ores extracted from the Earth are allowed to absorb carbon by a reduction process. In this natural reduction reaction, as the iron ore is heated with carbon, it results in a pop-marked surface ...

MIDREX Processes - KOBELCO

The process reduces iron ore using a reforming gas made from natural gas. The DRI is used mainly as the raw material for electric arc furnaces (EAFs), as a clean iron source substitute for scrap iron. Pores are left behind in the DRI after oxygen has been removed. These pores, if filled with water, for example, can cause the iron to reoxidize with ambient oxygen, generate heat and occasionally ...
