DETAILS Conversion of Sponge Iron From Low Grade Iron ore. The process of DRI or sponge Iron making can be classified into different categories as given below A Rotary Klin Process Rotary Kiln method is very important for sponge iron production using noncoking coal as a reluctant The Iron ore is charged from one end with noncoking coal which is in the lump form or pellets and heated from.Free Consultation
Tunnel Kiln Process For Sponge Iron Making . Can We Use Magnetite Ore For Dri Tunnel Kiln Process. sponge iron tunnel kiln process of iron ore reduction. low grade iron ore fines can be utilized, and further processing of produced hot of rotary hearth furnace .DRI, also known as sponge iron, is the product of reducing iron oxide in the form of iron ore and steel plant wastes into metallic iron, below the melting point of iron and typically in the range of 800–1200 C. Iron oxide is charged into shaft furnace, rotary kiln, or fluidized beds in the form of pellet, iron ore lumps, or fines. The reduction takes place using gaseous reductants (CO + H.2II. Rotary kiln Operation and construction details A schematic diagram of the rotary kiln of sponge iron process considered for the present work is shown in Fig. 1. The rotary kiln consists of a rotating cylindrical shell lined inside with refractory material. The kiln is around 80 m long with 4 m.Modeling of Rotary Kiln for Sponge Iron Processing Using CFD package (ANSYS 13.0) A Thesis Submitted for Partial Fulfillment of the Degree Award Of MASTER OF TECHNOLOGY In CHEMICAL ENGINEERING Under the supervision of.
This study focuses on sponge iron kiln based process. The chemical process involved in making sponge iron removes oxygen from iron ore by using a reducing agent in the form of non-coking coal [Patra et al, (2005)]. The reduction process is carried out in an inclined horizontal rotary kiln, which rotates at a programmed speed.8. Sponge Iron Rotary Kiln head hood including stationary type and flexible type. Working Principle Sponge Iron Rotary Kiln Sponge Iron Rotary Kiln is a cylindrical vessel, inclined slightly to the horizontal, which is rotated slowly around its axis. Sponge Iron Rotary Kiln to be processed is fed into the upper end of the cylinder.Sponge iron dri rotary kiln The introduction of Rotary kiln a, Rotary kiln is the main equipment for sintering cement clinker. b, The rotary kilns produced by our company can be divided into dry process and wet process.Sponge Iron Industry in recent years has witnessed growth in India as well as globally. Chhattisgarh blessed with abundant natural resources is one of major producers of Sponge Iron in India.
Production sponge iron through tunnel kiln process. production sponge iron through tunnel kiln process Sponge iron production by tunnel kiln method was developed from 1911 as H gan s method in Sweden After many modifications now this process is a sufficient and effective method for sponge iron production PDF Production of Sponge Iron through Tunnel Kiln Process .However, Rotary kiln process suffers from serious limitations like low productivity and pollution. In this respect fixed bed Tunnel kiln furnace are evolving as an alternative to Rotary kiln process. Iron ore fines and the low grade beneficiated iron ore cake are directly used for manufacturing of sponge iron.Process for production of sponge iron by direct reduction of iron ore wherein iron ore admixed with a carbonaceous reducing agent is passed through a rotary kiln countercurrent to a gas stream, and wherein granular coking high volatile coal is injected co-current to said gas stream as a solid reducing agent by means of oxygen containing gases through an inlet pipe, and said solid reducing.Iron Making Process Sponge Iron DRI Steel Making Iron ore Pellets Fe 64.0 SiO 2 traveling grate while pellets are fired in a rotary kiln by radiation. Hot pellets are cooled in a rotary cooler. Hot air from the rotary kiln is used in the grate for drying and preheating. The hot air from the cooler is.
DRI, also known as sponge iron, is the product of reducing iron oxide in the form of iron ore and steel plant wastes into metallic iron, below the melting point of iron and typically in the range of 800–1200 C. Iron oxide is charged into shaft furnace, rotary kiln, or fluidized beds in the form of pellet, iron.As touched upon earlier, sponge iron is mainly produced from ore by two different routes -(a) By reducing gases (CO and H 2 ) in a shaft furnace (b) Through direct treatment with coal in a rotary kiln.Sponge Iron -Sponge iron is the metallic product formed by the reduction (removal of oxygen) of iron ore at temperature below the fusion point of.In the coal based DR Process, the reducing gas is produced from non coking coal in the reduction zone of the furnace, typically a rotary kiln. Sponge iron plants The typical examples of coal based.Sponge Iron Composition Manufacturing Process. Sponge iron making is a process in which iron ore lumps typically 5mm18mm size are tumbled with a select grade of ironcoking coal little dolomite inside an inclined rotary kiln and control combusted in the presence of air for about 12 hours before the products are air cooled magnetically separated screened and size wise in finished.
