The Sintering Process of Iron Ore Fines | ispatguru
The Sintering Process of Iron Ore Fines Sintering plants are normally associated with the production of hot metal in blast furnaces in integrated steel pants , Use of sinter reduces the coke rate and enhances the productivity in blast furnace; Sintering process helps utilization of iron ore fines (0-10 mm) generated during iron ore mining .

The purpose of the sinter plant is to process fine grained raw materials into a coarse grained iron ore sinter, ready to be charged to the blast furnace Sintering of fine particles into a porous clinker – sinter – is necessary to improve the permeability of the burden, making reduction easier A high quality sinter has high reducability, which reduces the intensity of blast furnace .
Factors affecting Coke rate in a Blast Furnace | ,
Factors affecting Coke rate in a Blast Furnace BF is a counter current reactor in which the reducing gas is produced by the gasification of the carbon of the BF coke with the oxygen of the hot blast injected via tuyeres in the lower part of the furnace
Blast Furnace System | Industrial Efficiency Technology ,
While the former provides the necessary air flow at 3 – 5 bar pressure, the latter increases the temperature of air to 900 – 1350 o C Ore, sinter or pellets, coke and lime (that removes impurities and acts as flux) are added to the blast furnace from the top, whereas hot blast (compressed air) is introduced from tuyéres at the lower part .
Blast furnaces used in the ISP have a more intense operation than standard lead blast furnaces, with higher air blast rates per m 2 of hearth area and a , Iron ore + limestone sinter; Coke; Elevator; Feedstock inlet , which is used to increase the efficiency of the blast furnace The hot blast is directed into the furnace through water .
Influence of high grade iron ore usage on the performance of SEA Blast Furnaces BY OLIVEIRA, M VINICIUS *; KUMAR, PRACHETHAN **; OLIVEIRA, DAUTER *** , ratio with low LOI helps improve sinter strength, reduce BF slag rate and fuel rate, , The coke consumption, sinter productivity and sinter tumbler strength were the
influence on the coke rate and blast furnace productivity are (a) reduction properties (RDI/RI) of sinter, (b) Fe content in the sinter, and (c) fines in the sinter It has been conclusively proved in relation to the blast furnaces (BF) of SAIL- Bhilai.
Reduction in coke rate in blast furnaces SINTERING PROCESS A Sinter Plant typically comprise the following sub-units as shown below The raw materials used are as follows - Iron ore fines (-10 mm), coke breeze (-3 mm), Lime stone & dolomite fines (-3mm) and other metallurgical wast
The function of the Sinter Plant is to supply the blast furnaces with sinter, a combination of blended ores, fluxes and coke which is partially ‘cooked’ or sintered In this form, the materials combine efficiently in the blast furnace and allow for more consistent and controllable iron manufacture
Blast Furnace and Stov Blast Furnace , The furnace is charged with sinter pellets and rubble ore (iron bearing materials), flux and coke Conventionally, the materials are charged through a rotating hopper distributor and two-bell system, although many modern furnaces have the Paul Wurth bell-less top which uses a rotating chute .
The parameters which have the greatest effect on coke rate and shop productivity are the coke abradability index M 10, the iron content of the furnace charge, blast temperature, and sinter basicity For example, a 1% decrease in the abradability index decreases coke rate by 712 kg/ton pig (see Table 3 )
