the idea of the process of how to make sponge iron from iron ore is basically to add coal to remove oxygen from iron by adding non coking coal and to remove sulfur by adding lime stone, the iron ore and coal are crushed in crushers and screened to the recommended sizes (5mm- mm), then mixed and heated to degrees centigrade s, the mixture is treated in rotary kiln process with air control ...
This report is one of a series of publications resulting from a comprehensive effort initiated by the Institute of Medicine's Food and Nutrition Board in 1993 to expand the approach to the development of dietary reference standards. The new categories of reference values have specific uses and thus are a significant departure from the previous Recommended Dietary Allowances (RDAs) in the ...

VIU Methodology • The method used to evaluate the value of HBI/DRI and pig iron resulting from the absence of residuals involved looking at direct substitution of higher cost grades of scrap with a blend of OBM and a lower value, high residual scrap grade.
An optimization mass and energy balance has been developed for Electric Arc Furnaces operated with DRI. The model involves linear programming in order to define a metallurgical practice with the lowest production cost. The most recent thermochemical database was also included in the thermal balance. A higher consumption of electrical ...
MASS AND HEAT BALANCE OF STEELMAKING IN BOF AS COMPARED TO EAF PROCESSES M.M.LOTFY1, H.A.AHMED2 AND F.A.ELREFAIE3 ABSTRACT Mass and energy balance equations are applied on top blowing BOF and EAF steelmaking processes to detect the energy profile of production one ton steel by both processes. An

for 3.5%C DRI 14 and extrapolates to 4%C DRI production. For FASTOx, where FASMELT HM (FASTIRON) is fed to a BOF, the internal FASTMET 11,12,13 analysis has been coupled with BOF published data 2,3,4,5. In all cases, the format used for the process operations' energy input and output, is shown in Table IIa.
The MIDREX process produces direct reduced iron (hereinafter referred to as DRI ). The process reduces iron ore using a reforming gas made from natural gas. The DRI is used mainly as the raw material for electric arc furnaces (EAFs), as a clean iron source substitute for scrap iron. Pores are left behind in the DRI after oxygen has been removed.

Steel making today and tomorrow . ... Hydrogen storage of sufficient capacity is used to balance between the DRI- process and the electricity grid allowing a significant amount of intermittent power generation by e.g. wind or solar power plants to be connected/to be connected to it. The sponge iron can be used as hot DRI and melted immediately ...
the kiln process chemistry. This article tries to establish detailed energy audit methodology of sponge iron manufacturing process or kiln operation with a view to finding out major energy sav-ing potential of the unit. In the research work we find that it is the incomplete reaction of coal that causes the major energy inefficiency in the process.
Mar 16, 2013· Fig 1 DRI process principle. Major DRI production processes are either gas based or coal based. Feed material in a DRI process is either iron ore sized to 10 to 30mm or iron ore pellets produced in an iron ore pellet plant. In the gas based plant the reactor, the reduction reaction takes place is a .
Hot direct reduced iron (HDRI) is DRI that is transported hot, directly from the reduction furnace, into an electric arc furnace, thereby saving energy. The direct reduction process uses pelletized iron ore or natural "lump" ore. One exception is the fluidized bed process which requires sized iron ore particles.
Mathematical model of the SL/RN direct reduction . rotary kiln as thereactorratherthan a vertical shaft. The importance of this process restsin the fact that the coal, which is preferably noncoking, is used without treatment; and is therefore less ex-pensive than reducing gas which is obtained either by reforming natural gas or by gasifying coal.
