Accretion Control in Sponge Iron Production Kiln using ...
The performance of rotary kiln sponge iron based processes is normally affected by accretion build up along the kiln linings. Accretion build up is the accumulation of semimolten material which form rings along kiln lining. These rings narrow the kiln diameter thereby hindering efficient material flow and effect lowering production rate and performance of the kiln. PID controllers have been ...

Control of Slag and Insoluble Buildup in Ladles, Melting ...
ductile iron production has experienced continued growth, the quality of metallic scrap and other iron unit feed stocks has steadily deteriorated. The result: slag related melting problems have become widespread issues in recent years. Yet, a search of the foundry technical literature from the past 30 years about slag control and buildup will result in only a handful of articles. A new flux ...
MIDREX® Process
· The MIDREX® Direct Reduction Process fueled by natural gas paired with an electric arc furnace (EAF) has the lowest CO² emissions of any commercially proven steelmaking route using iron ore at – kg CO² / kg steel. To maximize the efficiency of reforming, offgas from the shaft furnace is recycled and blended with fresh ...
Development of energy conservations scenarios for sponge ...
· In sponge iron process variation in temperature of iron ore, coal, dolomite, sponge iron, and waste gas is in the range from 1,020°C to 30°C. Though specific heats of these materials vary considerably with change in temperature, in the present work these variations are taken as negligible. The reason behind this assumption is that the present work deals with the comparative study among ...

Sponge iron industry needs quick actions for survival ...
· While gasbased sponge iron process is highly ecofriendly and energy efficient, coalbased sponge iron process is a highly energy intensive activity and leads to higher carbon load on climate, especially by smaller units. Inadequate availability and uncertainty in the prices of iron ore NMDC is the prime source of iron ore for sponge iron producers as they have almost reserves of sponge ...
Iron Recovery from Bauxite Tailings Red Mud by Thermal ...
not available. Due to the high content of iron oxide (30–60% wt.) red mud ranks as a potential raw material for the production of iron through a direct route. In this work, a novel process at the laboratory scale to produce iron sponge ( 1300 C) or cast iron (> 1300 C) using blast furnace sludge as a reducing agent is presented. Red mud ...
