Pressure inside a coal fired sponge iron rotary kiln depends on several operating parameters such as coal injection rate, ore feed rate, moisture, and primary and secondary air blow rates ...
The temperature profiles of the gas and charge in a coal-fired rotary sponge iron kiln affect both the iron ore reduction process and accretion formation. The temperature profile of charge is ...
Innov Engineering advanced tunnel kiln technology is arguably the most sufficient and effective method for sponge iron production which allows for economically feasible plants.
Many efforts have been put into effect to make the steel making efficient through induction furnace route. The main raw materials for induction furnaces are steel scrap, sponge iron and cast...
According to this experiment it was shown that the sponge iron might be easily produced by tunnel kiln.
Abstract: The present investigation deals with the feasibility study of the process development for production of Directly Reduced Iron (DRI) using waste/low grade iron ore (slime), mill scale …
The invention discloses a technology for producing sponge iron in a tunnel kiln. The technology mainly solves the problems that an existing tunnel kiln technology is low in capacity, high in energy consumption, large in loss and the like. Raw materials, a reducing agent and additives are mixed and subjected to ball milling to obtain a ball grinding material; the ball grinding material …
i need some resources about the production process and raw material of Silicon carbide saggers in sponge iron reduction via the tunnel kiln method.
The max. temp of the kiln was kept at about 1300°C. The seduced products were solid mass of sp. gr. about B.G. The sp. gr. of 7 may be obtained, if desired, by suitably charging conditions. According to this experiment it was shown that the sponge iron might be easily produced by tunnel kiln.

The product gases from coal-fired sponge iron kilns exit at a high temperature (800-950 o C) and contain some unburnt carbon and carbon monoxide along with nitrogen, carbon dioxide and entrained dust.
VOL. 5 NO. 1 OCTOBER, 2010 STEEL TECH 11 from an industrial coal-based sponge iron rotary kiln process. We have developed a fairly comprehensive mathematical model for the direct reduction of iron ore
production of sponge iron was investigated with calcium carbonate, sodium carbonate, and barium carbonate cata-lysts under different conditions using the tunnel kiln meth-od. The …
Processes that produce iron by reduction of iron ore in solid state are generally classified as direct reduction (DR) processes and the products also referred to as direct …
Sponge Iron and Smelting Reduction Sectional Committee, MTD 30 FOREWORD ... In this revision, the carbon content for rotary kiln DRI/sponge iron has been modified to around 0.1 percent apart from the size range of sponge irori. Direct reduction (DR) is a metallurgical process of producing iron from iron oxides (mainly in the form of lump ...

These plants use iron ore pellets in the rotary kiln. Raw material mix consisting of iron ore, dolomite and non-coking coal is fed at the one end of the rotary kiln and is heated by coal burners to produce DRI. The product DRI along with char (sometimes called dolo char) is taken out from the other end of the kiln. ... Equivalent metallization ...
Sponge Iron Kiln Main Structure. Sponge iron kiln's kiln head steal: Sponge iron kiln adopts kiln shell gas seal and spring steel sheet double-layer flexible sealing device. The cold air enters the cooling shield through the bell mouth, and is exhausted after being heated.
