Krupp Sponge Iron Process The Krupp. Sponge iron process uses a rotary kiln for the reduction of high grade lump ores or pellets (Fig. 1). The feed is introduced together with reducing and de-sulphurizing agents (lime-stone or raw dolomite) into an inclined rotary kiln, heated counter current to the flow of hot gas and reduced to form sponge,Sponge Iron Production Process - Arij Trading,Sponge iron production process discussed herein are selected from known methods of which the references are available and referable. We look at the 4 different methods of producing sponge iron: Midrex process. HYL process (4th generation) or Energiron. SL / RN process. Tunnel furnace process.
ENERGY INTEGRATION IN SPONGE IRON PLANT USING HEAT OF,
sponge iron making was in 1972 presumably using a rotary kiln. More than 100 DR processes have been invented and operated since 1920. Most of these have died down but some of them have re-emerged in slightly different form. [6] Sponge iron is mainly produced from iron ore by two different routes – (a) - by reducing gases (CO and H 2Development of energy conservations scenarios for sponge,,16-01-2011· Therefore, case 8 is selected as final design for energy integrated sponge iron process plant which is shown in Fig. 6. Further, it is seen from Table 5 that for the existing system 7.1 times more energy is required than the theoretical value and by proper energy integration through case 8 this value is reduced up to 6.2.Modelling and optimization of a rotary kiln direct,,kiln model developed from first principles to evaluate designs for its clients. This tool has been applied to a variety of pyrometallurgical applications. This paper illustrates the application of numerical optimization techniques in combination with the kiln model in the interrogation of a generic iron-ore reduction process.Sponge iron making process - SlideShare,09-11-2014· Sponge iron making process 1.

SPONGE IRON UNIT - SEIL
The material is cooled down to 100oC and fed to magnetic separator for separating the sponge iron and non-magnetic (char). The Sponge Iron is conveyed to the Storage Silos for dispatch. 7. When the material is travelling downward in the kiln, the hot gases travel in opposite direction. These gases are utilized for power generation through WHRB.OPERATIONAL ASPECTS OF SPONGE IRON PRODUCTION IN A ROTARY KILN,1.

Coal based Direct Reduction Rotary Kiln Process – IspatGuru
14-02-2017· Normally for rotary kiln process volatile matter is to be in the range of 25 % to 30 %. Coals for direct reduction in the rotary kiln need to have low swelling index. Normally swelling index is to be less than 1. The physical and chemical specifications of the non-coking coal are as follows. Size of lumps – 5 mm to 20 mm.SLRN process - Metso Outotec,Our standard rotary kiln (4.8 x 80 m) is capable of producing up to 160,000 tons DRI per annum depending on the raw material.
