Embodiment Construction

[0078] exist figure 1 The ironmaking process shown in uses iron-bearing feedstock in the form of iron ore powder to produce molten iron and includes:

[0079] (a) a direct reduction process which partially reduces solid iron ore powder in a direct reduction vessel in the form of a circofer circulating fluidized bed reactor 3; and

[0080] (2) A molten bath direct smelting process which involves combining (i) solid feedstock in the form of partially reduced iron ore powder and solid carbonaceous material in the form of synthetic coal from reactor 3 and (ii) industrial grade Oxygen is supplied to the direct melting vessel 5, the iron ore that has been partially reduced is melted and further reduced, and molten iron is produced.

[0081] More specifically, refer to figure 1 A process flow diagram for the process of combining (i) solid feed from reactor 3 in the form of partially reduced iron ore powder and (ii) gas, i.e. by scrubbing CO from the off-gas 2 The oxygen and enri...

Abstract

The invention discloses a method for iron-smelting which comprises: a direct deoxidizing process which partly deoxidizes material with iron and produces part deoxidized material with iron; a direct smelting process which smelts part deoxidized material with iron and produces smelting raw iron, slag and discharge gas; and a process which collects CO2 from discharge gas without releasing the discharge gas to air.

Description

technical field [0001] The present invention relates to an ironmaking method. [0002] The present invention relates particularly, but not exclusively, to an ironmaking process which employs carbon as a recirculating reducing agent in the process. Background technique [0003] In general, according to the present invention there is provided an ironmaking process for the production of iron from an iron-containing feedstock, the process comprising: [0004] (1) a direct reduction process comprising providing an iron-containing feed material to a direct reduction vessel, at least partially reducing the feed material in the vessel, and producing the at least partially reduced iron-containing feed material; [0005] (2) a direct smelting process which includes supplying solid feedstock from the direct reduction process (1) in the form of a partially reduced iron-containing feed to a direct smelting vessel together with (i) solid carbonaceous material and (ii) an oxygen-containin...
