Direct Reduction Process an overview ScienceDirect

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

DRI production International Iron Metallics Association

DRI production. Direct reduction of iron is the removal of oxygen from iron ore or other iron bearing materials in the solid state, i.e. without melting, as in the blast furnace. The reducing agents are carbon monoxide and hydrogen, coming from reformed natural gas, syngas or coal. Iron ore is used mostly in pellet and/or lumpy form.

Direct-Reduced Iron an overview ScienceDirect Topics

In direct reduction the ore is heated to temperatures below its melting point. Direct energy requirements per net ton of direct reduced iron are in the order of 10,000 MJ. The product is 90 to 95% metallized and hence is suitable as a charge in blast, basic oxygen, and electric arc furnaces.

Titanium-vanadium slags produced upon the direct

The phase compositions of complex titanium-vanadium slags that form upon the processing (using the direct reduction of iron) of titanium-magnetite concentrates of ten CIS deposits are studied by X-ray diffraction and optical and scanning electron microscopies. Depending on the phase composition, these slags can be divided into the following three groups: spinellide, anosovite-spinellide, and

Article: Comparative study on the properties of UO 2

The UO 2 powder was produced by two different methods: (1) by the reduction of the thermal decomposed product of ammonium diuranate and (2) by the direct reduction of ammonium diuranate. Oxygen to uranium ratio (O/U), specific surface area (SSA) and crystal structure of UO 2 powder produced by these two methods were studied.
