coal-based DRI. Out of the global DRI production of 68.5 million tonnes in 2008, the production of coal-based DRI occupies 17.6 million tonnes, which equates to 25.7% of the total1). Most coal-based reduction processes including SL/RN2) employ rotary kilns. Pellets, or lump-ore, mixed with coal are/is charged into the rotary kilns2) and heated
What are HYL and SL/RN technologies - key features, advantages and disadvantages of these two Direct Reduction iron making processes HYL III and SL/RN - The two widely accepted Direct Reduction (DR) Processes of ironmaking - Industry.Guru
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 ...
Sponge Iron Roller Kiln Reduction Technology. Slrn process outotec. the process principles are the basis for numerous rotary kiln plants and still represent the dominant technology for the direct reduction of lump ore or pellets using coal. ... lump ore, beach sand, ilmenite and also iron ore fines with slrn.
Direct reduction processes may be classified, according to the type of the reducing agent used, to gas-based and coal-based processes. In 2000, DRI produced from the gas-based processes accounted for 93%, while the coal-based processes produced 7%. Gas-based processes have shaft furnaces for reducing.

The coal based direct reduction rotary kiln process was developed for converting iron ore directly into metallic iron without the.
However, coal consumption is considerably higher than for a blast furnace and the energy efficiency of individual plants depends on the efficient use of the large amounts of residual gas isSL/RN process is a kiln based process that uses . This is the most widely used coal based direct reduction process.
Manufacturing process coal based direct reduction process is classified based on the reducing agent namely solid most solid reduction process use noncoking coal as reducing agent due to abundantly available noncoking coal the process proposed to be adopted is the rotary kiln proposes using noncoking coal and iron ore.

The MIDREX® Direct Reduction Process fueled by natural gas paired with an electric arc furnace (EAF) has the lowest CO² emissions of any commercially proven steelmaking route using iron ore at 1.1 – 1.2 kg CO² / kg steel.
slrn process direct reduction iron, process is a widely used coal-based DRI-making process which uses a rotary kiln, coal consumption is considerably higher than for a blast furnace and the energy efficiency of individual plants depends on the efficient use of the large amounts.
Coal based direct reduction process is based on the solid reducing agent which is non-coking coal. The reaction takes place at high temp (1000 deg C to 1100 deg C). Coal plays a dual role in the kiln. Part of coal is used as fuel to supply the desired heat so as to take the raw materials to the desired temperature.

Midrex Process for Direct Reduction of Iron Ore – Midrex is an ironmaking process, developed for the production of direct reduced iron (DRI). It is a gas-based shaft furnace process is a solid state reduction process which reduces iron ore pellets or lump ore into DRI without their melting using reducing gas generally formed from natural gas.
Producing Iron With Slrn Process.Slrn process outotec. the slrn process was developed in the early 1960s by outotec in collaboration with three us companies. the process principles are the basis for numerous rotary kiln plants and still represent the dominant technology for the direct reduction of.
Such a process combination enables steel to be produced without using coking coal, which is an expensive input in the normal blast furnace—basic oxygen furnace route of steelmaking adopted in integrated steel plants. The book offers comprehensive coverage and critical assessment of various coal-based and gas-based direct reduction processes.
