developments in blast furnace iron making. Introduction Kobe Steel started operation as an integrated steel manufacturing company with the blowing-in of the No. 1 blast furnace (BF) at the Kobe Works in 1959.1) We as latecomers faced an issue with burden materials which forced us into high pellet ratio operation requiring central gas flow. A Before iron ore can be used oxygen must be removed from it. Known as reducing this can be done either in the blast furnace where hot air is injected into a continuous feed of coke sinter and lime or by the direct reduced iron (DRI) process. The result from both is liquid iron which is then transported to the basic oxygen furnace. The blast furnace process also produces two

Basically the blast furnace is a countercurrent heat and oxygen exchanger in which rising combustion gas loses most of its heat on the way up leaving the furnace at a temperature of about 200° C (390° F) while descending iron oxides are wholly converted to metallic iron. Blast furnaces are used to produce pig iron from iron ore for subsequent processing into steel and they are also employed in processing lead copper and other metals. Rapid combustion is maintained by the current of air under pressure. A zinc-lead blast furnace and lead-splash condenser.

We had expected that no new blast furnaces would be built in the developed world we will see new blast furnaces in Brazil and India as well as many in China. Iron Making Crude steel production begins with the reduction process where the iron ore reacts with carbon sources inside the blast furnace. The blast furnace requires different types of refractory products with resistance to thermo-mechanical and thermo-chemical reactions.

Blast furnace gas is produced during the iron oxide reduction in blast furnace iron making in which iron ore coke and limestone are heated and melted in a blast furnace and is an indigenous process gas of the steelworks industry (Pugh et al. 2013). At present the blast furnace ironmaking is still the dominant process in ironmaking. Despite the apparent environmental advantages of the new ironmaking technologies the blast furnace is still predicted to be the single largest process for ironmaking from iron ore until 2050.

1. Brief introduction of iron blast furnace. The pig iron blast furnace provides the means by which iron is rapidly and efficiently reduced from iron ore and it is the basis for all primary steelmaking. The structure of pig iron blast furnace is made of steel plate and refractory bricks and its shape is vertical drum like bowling pin. The insides of blast furnace can be divided into hearth Jul 16 2017 · Blast furnaces existed in China from about 1st century AD and in the West from the High Middle Ages.They spread from the region around Namur in Wallonia (Belgium) in the late 15th century being introduced to England in 1491.The fuel used in these was invariably charcoal.The successful substitution of coke for charcoal is widely attributed to Abraham Darby in 1709.
