In this method heat coal as a reducing agent is mixed with iron ore and sponge iron is produced in a horizontal furnace. Input iron ore In the Midrex or HYL process it is generally recommended to use high quality cooked pellets with a maximum of about 30 iron ore lumps.
Oxygen analysis is carried out by combustion in a LECO oven. The reduction of mill scale allows the new use and development of this material to obtain sponge iron that can be re-used to the electric furnace as metallic load in steel manufacturing or as a raw material in the production of
Sponge iron process might well be scaled up to a commercial operation a full-scale test was car-ried out in a production kiln of 4.6 m diameter and 110 m length which had been modified to suit the conditions encountered in processing rich iron ores. This test furnished proof that the test results are reproducible on a production scale.
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. The process involves heating the naturally occurring iron oxide in the presence of carbon which produces sponge iron. In this process the oxygen is removed without melting the ore.
Four sponge iron SI1 SI2 SI3 and SI4 plants with different installed capacity and sponge iron SI production have been considered for studies based on the baseline methodology. Figure 3.3.18 shows the annual SI production across sample plants. The production varies from 0.06 SI1 to 0.2 Mt SI4. Sign in to download full-size image
showed that owing to its high porosity the sponge iron produced by H gan s could readily be comminuted to iron powder. Production of iron powder started on a small scale at H gan s in Sweden between 1937 and 1939 and regular shipments were made to the USA. These early grades of sponge iron powder were unannealed containing up to 2 of reducible oxygen H 2
Sponge Iron is a recognized alternative to steel scrap as a raw material for the manufacture of various steel products. The twin issues of rapid depletion of Coking Coal reserves and the scarcity of indigenous scrap made the Government of India support production of sponge iron in the country.Sponge iron is a metallic product produced through direct reduction of iron and iron ore pellets in the solid state. It is
Sponge Iron also called Direct reduced iron DRI is produced from the direct reduction of iron ore in the form of lumps pellets or fines to iron by a reducing gas or elemental carbon produced from natural gas or coal. Many ores are suitable for direct reduction.
Cane Crusher Mill can be made according to Sugar production. We Manufacture all type of 4 roller 5 roller and 6 roller mills where 4 roller mill is a most common roller mill in India. Material Rollers are made up of hard coarse grain cast iron shells shrunk fitted on forged alloy steel shaft with square ends.
Small scale production enjoys certain unique advantages and disadvantages. It is a major contributor of industrial output exports employment and national income in many developing countries. Disadvantages of small scale production. Small scale production suffers from the following disadvantages 1.

Sep 15 2006 Almost 80 per cent coal-based sponge iron manufactured in the world comes from India and about 60 per cent of this production comes from the small-scale industry in the unorganised sector. Some of these are unregistered companies and it is therefore impossible to have an accurate count of how many plants are operating in the country.

process the iron from the blast furnace is con-verted to steel in a basic oxygen furnace BOF. Steel can also be made in an electric arc furnace EAF from scrap steel and in some cases from direct reduced iron. BOF is typically used for high-tonnage production of carbon steels while the EAF is used to produce carbon steels and low-
