Tunnel Kiln Tunnel Kiln Manufacturer India – Electrotherm ... Quality of sponge iron made by the Tunnel Kiln technology is superior as compared to that made from the rotary kilns because, while the input raw material gets just about 24hours for the reaction, the figures almost reverse in case of the Tunnel Kiln.
direct reduction of iron ore from tunnel kiln process. Sponge Iron Dri Plant Made By Tunnel Kiln Buy Tunnel Kiln By using tunnel kiln to produce DRI is that mix the iron ore concentrate, pulverized coal and for reduction and cooling, iron ore concentrate will be reduction and get the direct reduced iron.
corbothermic reduction of iron in tunnel kiln. Keywords: Sponge iron, tunnel kiln, energy e ciency, exhaust, pushing time, district heating, energy survey, energy balance. reduction mix and the ore are dried before charged in the capsules. [1] An overview of the flows in the process is shown in figure 1. The tunnel kilns. Reduction mix. Iron ore.
Solid phase reduction is made at relatively low temperature and low grade steam coal is used as a reducing agent. The reduction process is distributed along the structure of chrome spinellide of anion vacancies with the excess of electrons. Metal iron and chrome alloy is the prime product of reduction.
These Tunnel Kiln is thermal equipment for longterm continuous production. The carbothermic reduction of iron ore takes place in the tunnel kiln. The reduction mix, consisting of coal or coke fine and limestone, is charged with iron ore briquette in Sic container.
Reduction Of Iron Ore By Charcoal Under Microwave Irradiation 44 Reducing agent used in this research was charcoal which has fixed carbon content approximately % and the small amount of sulfur. Charcoal was mashed into microscopics scale up to 100 mesh in size using Ball Milling (Retsch PM400 MA type). B. Reduction Process
In iron reduction processes, a reducing agent, based on carbon or hydrogen, removes the oxygen from the iron. This removal can egories are material preprocessing, iron reduction, steel production and casting, rolling and finishing. Coke is essential in the blast furnace.
