摘要： Particulate iron ore is reduced to sponge iron in a vertical shaft reduction reactor by forcing the ore upwardly in a moving bed counter-current to a descending stream of hot reducing gas produced by the gasification of coal in a gasifier, for example, a melter-gasifier, containing a molten iron bath and producing a hot dust-laden gas. The product sponge iron may be used as a feed material for the molten bath in the gasifier. The reactor is equipped with a gas outlet plenum containing a renewable body of ore to minimize clogging at the gas outlet.

摘要： Improved operation of the broadly known combination of a moving bed, gaseous reduction reactor for reducing iron ore and a melter-gasifier for converting to molten metal the sponge iron pellets produced in such a reactor is achieved by preparing a mixture of finely ground sponge iron and coal, either by mixing the sponge iron and coal and then grinding or by separately grinding the sponge iron and coal and then mixing, and feeding the mixture of finely ground coal and sponge iron, along with elemental oxygen, to a point below the surface of a molten metal bath within the melter-gasifier.

摘要： A method and apparatus for increasing the productivity of an existing direct reduction iron (DRI) plant without increasing its reformer capacity existing in the plant. This object is achieved by not only recycling some effluent gas of the reduction reactor to the gas reformer (with natural gas or the like added with an oxidant as make up gas), but also recycling an additional portion of the effluent gas with added natural gas and an oxygen containing stream directly to the reducing gas stream exiting the reformer prior to or as part of its introduction to the reduction reactor, thereby providing additional reducing agents and increasing the reducing capacity of the plant. The oxygen containing stream is preferably added to the recycled reducing gas without preheating. Any excess or purged effluent gas is as usual burned as fuel.

摘要： A method and apparatus for producing direct reduced iron using a melter-gasifier and two reduction reactors. In the first reduction reactor, iron ore is prereduced using a reducing gas from a melter-gasifier. This prereduced iron ore is fed into the melter-gasifier to produce pig iron. A secondary reducing gas comprising hydrogen and carbon monoxide is withdrawn from the first reduction reactor and is reacted with water to produce carbon dioxide which is subsequently removed to produce a tertiary reducing gas that is used in the second reduction reactor to produce direct reduced iron from iron ore.

摘要： In method and apparatus for producing iron and steel from iron cores largely composed of iron oxides, wherein a direct reduction process is used to produce a solid particulate intermediate product, generally known as sponge Iron or Direct Reduced Iron (DRI); pneumatically conveying large iron-bearing particles, such as pelletized iron ore or particularly DRI, in a closed transport pipe, eg. from the reduction reactor of the direct reduction process to the metallurgical furnaces where liquid iron or steel are produced, for example electric arc furnaces, induction furnaces, basic oxygen furnaces, etc. or to a briquetting press to form DRI briquettes, or simply to a silo or storage bin, or in general to a subsequent processing step for said DRI. When the carrier gas is recirculated for reuse, surprisingly air can be a preferred source of such gas, especially for reactive hot DRI. This method has a superior efficiency and productivity and reduces the overall energy consumption relative to currently used DRI steelmaking plants.By using pneumatic conveyors, elements of the plant may be arranged side by side rather than one on top of the other, whereby the overall height of the plant may be reduced.

The valve comprises a pipe made of a non-magnetic material with at least two elements of magnetic material such as iron or carbon steel, vertically spaced apart along said pipe (which advantageously separately ring said pipe and contact the interior thereof) and a plurality of means to selectively create or eliminate or decrease the intensity of a magnetic circuit which passes through said elements and through said ferromagnetic material in such a way that said material is stopped or its flow is diminished when the magnetic field flows therethrough and the flow is allowed when said magnetic field is diminished, deleted, or deviated.
