Raw Materials Used In Blast Furnace
Raw Materials Used In Blast Furnace. The three main raw materials used to make pig iron (which is the raw material needed to make steel) for primary steel production in a blast furnace are the processed iron ore, coke (residue left after heating coal in the absence of air, generally containing up to 90% carbon) and limestone (caco3) or burnt lime. It is a hard but brittle metal and the impurities severely hamper its strength.
Because of the nature of the process, the bf process is essentially sensitive to burden material size, the distribution, and the strength. Raw material for cement the largest demand for blast furnace slag is. Raw materials for blast furnace iron making iron ore for b/f (a)haematite (fe203),magnetite (fe304).with size more that 10 mm.
The Principal Raw Materials Used In The Blast Furnace Operation Consist Of 1.
Beneficiation of iron ore the methods available for the beneficiation of iron ore include. In this study, the reactivity of ts was improved by mechanical grinding,. Smelting taconite in blast furnace raw materials used.
The Test Pellets Are Produced Either In The Steel Belt Plant Located In Malmberget Or In One Of The Grate Kiln Plants Located In The Kiruna Area.
To adjust alumina / silica ratio; The main application of the blast furnace is to smelt the iron from its ore and the pig iron formed during the process is used for the production of various grades of steel. Sinter and pellets are together often referred to as agglomerates.
Iron Ore And Agglomerates Introduction All Over The World, Substantial Improvements In Blast Furnace Performance Have Been Brought About By Using Superior Quality Raw Materials.
Pulverized coal / tar etc. 2.2 raw material preparation and dust treatment the raw materials for the experimental blast furnace are normally produced before each campaign. What raw materials are added to the blast furnace?
The Raw Materials Require 6 To 8 Hours To Descend To The Bottom Of The Furnace Where They Become The Final Product Of Liquid Slag And Liquid Iron.
Because of the nature of the process, the bf process is essentially sensitive to burden material size, the distribution, and the strength. The bf burden materials consist of coke, sinter, pellets, calibrated lump ore (clo), limestone, dolomite, manganese ore, and quartzite. This is called pig iron.
Chapter 09 Raw Materials Ii:
Pellets are made using normal Fuel(thermal requirement ) and reductant(chemical requirement) (a)coke from top (b)coal from tuyers 11 | p a g e ©oxygen flux Metallurgical coke, ferrous bearing feeds and fluxes charged via the furnace top.
