a process for producing pig iron is described, which contains a reducing shaft furnace 1 and a melting gasifier 2. the sponge iron produced from iron ores in the reducing shaft furnace is supplied to the melting gasifier and converted there into a pig iron melt. the gas produced in the melting gasifier is supplied directly via a line 4 as reducing gas to the reducing shaft furnace.
this invention relates to a process of producing iron. the invention, more precisely, refers to a process of iron production using a reactor, into which the reactants are injected beneath the surface of a molten bath. a reactor for gas production where pig iron production occurs is known from canadian pat. no. 1,097,078.
bessemer converter, schematic diagram. the bessemer process was the first inexpensive industrial process for the mass production of steel from molten pig iron before the development of the open hearth furnace. the key principle is removal of impurities from the iron by
in a separate process in a melter gasifier, these vile smelling, and highly toxic, compounds are almost completely combined in sponge iron, aggregates, and slag. in conventional pig iron production at iron works, coking coal is first mixed with charge consisting of pellets, sinter and lump ore, and then the mixture is put into a blast furnace.
nowadays, over 93 of the total iron production from ores is taking place via bf route. an alternative route for iron production is direct reduction, which is described more thoroughly in a separate chapter. figure 1.1.1 illustrates the position of the blast furnace as well as direct reduction in the overall steelmaking process 8.
quebec iron and titanium (qit fer et titane) in sorel, canada where coarse ilmenite is smelted to produce a high-tio2 slag and pig iron in similar furnaces. this technology was adapted for rbm to process the fine ilmenite concentrate mined on the north coast of kwazulu-natal.5 the process generates very little in the way of waste products.

ductile iron is made by the treatment of molten iron with no-dulizing (spheroidizing) material. during this treatment, gra-phite changes from flakes to nodules or spheres. the treatment process is a key operation in the production of ductile iron that ensures a predetermined microstructure, and mechanical and engineering properties of castings.
broken from the runner (the sow) hence the name pig iron. pig iron types are used to dilute all the elements in ductile iron which is a harmful process. pig iron contains low residual, lower nitrogen steel, has a consistent chemistry, promote slag conditions and improve process control.
process flow diagram of pig iron production. production of pig iron by using the romelt process. the romelt process of reducing molten is a continuous one phase process used in the production of liquid pig iron from various raw materials that containing iron and waste with the use of coal figure 1 shows a general layout of a romlet unit where
