Sponge Iron an overview ScienceDirect Topics

Pig iron is the basis of a majority of steel production. A majority of steel produced in the world is created through pig iron production. Sponge iron. Removing oxygen from the ore by a natural process produces a relatively small percentage of steels in the world. This process uses less energy and is a natural chemical reaction method.

PROCESS FOR PRODUCTION OF SPONGE IRON

Process for production of sponge iron by direct reduction of iron ore wherein iron ore admixed with a carbonaceous reducing agent is passed through a rotary kiln countercurrent to a gas stream, and wherein granular coking high volatile coal is injected co-current to said gas stream as a solid reducing agent by means of oxygen containing gases through an inlet pipe, and said solid reducing agent becomes admixed with the iron ore

PRODUCTION OF IRON AND STEEL POWDERS

2. PRODUCTION OF IRON AND STEEL POWDERS 8 2.3 The Höganäs Sponge Iron Process The Höganäs sponge iron process, is essentially a chemical process in which finely divided iron ore is being reduced with coke breeze yielding a spongy mass of solid metallic iron, which can readily be comminuted to iron powder. The iron ore used at

Sponge iron: property, methods of production, application

Sponge iron is obtained by reducing concentrates or high-quality iron ores under conditions of exposure to relatively low temperatures, less than 1100 degrees Celsius. Such processes eliminate the smelting of ore and its sintering.

iron could be lowered to 3.5-3.7 kilo-caloriesIton of sponge iron with partial recirculation of char. The trials yielded adequate data for designing a commercial prototype, or for industrial production of sponge iron. Introduction The direct reduction processes, developed for converting iron ore directly into metallic

The reasons for the success of Sponge Iron Industry in

Thus, sponge iron prepared through the reduction of iron ore using non-coking coal or natural gas as reductant was developed as a substitute for ferrous scrap. The consumption of sponge iron by EAF typically range 60-80% as an input with the metallic scrap, hence, easing the demand for steel scrap.

Sponge iron Manufacturing process Azerbaijan Simurgh

Raw materials for the production of sponge iron include iron ore, non-coal, and dolomite. For direct iron ore regeneration, the main kiln used is the rotary kiln. The spherical or spongy spherical parts, which are produced by the direct reduction of iron ore (Direction Reduce Iron) and the removal of oxygen, are called sponge iron.

production of steel & iron ore requirements

Units Production Iron ore requirements EAF Units 14.82 23.71 Sponge Iron Units 18.50 29.60 Total: 53.31 Note: Assuming no scrap is being used. For producing one tonne of crude steel, 1.6 tonnes of iron ore consumption has been assumed. If we add iron ore requirements of RINL of about 5.00MT (3.13 MT x 1.6 tonnes), the total iron

sponge iron process

7/29/2010· In general sized iron ore of 5-18mm is used in the process of manufacture of sponge iron on all types of rotary kiln with +16mm not exceeding 15-20%.The mean particle size of iron ore shall be restricted to 11mm in order to achieve uniform Fe metallic of all grain size fraction of the product.

Steel making process ArcelorMittal

In the former process, iron ore is the main raw material. In an electric furnace, scrap iron is used and occasionally also sponge iron. Sponge is an intermediate product, which is produced from iron ore by means of direct reduction (= DRI or directly reduced iron) and that is then further reduced and smelted in an electric furnace.
