Apr 19 2012 The steel making process in the oxygen converterconsists of Charging steel scrap Pouring liquid pig iron into the furnace Charging fluxes Oxygen blowing Sampling and temperature measurement Tapping the steel to a ladle Deslagging The iron impurities oxidize evolving heat necessary forthe process The forming oxides and sulfur are

Manufacturing Process of Cast Iron Castings

Used by itself pig iron has few uses due to its brittle nature Alloyed with other metals pig iron takes on new uses Making Cast Iron The term cast iron is generally used to describe grey cast iron but it can also describe a whole group of alloys too The surface color of the cast iron is often used to identify it

Corex Process in Iron Making SlideShare

Dec 02 2009 ii Absence of post combustion means that much chemical energy is lost in the exit gases and consequently the coal consumption in Corex is much higher than in any other iron making process iii The system is maintenance oriented including cooling gas compressor for recycling part of COREX gas for cooling the hot gases from the meltergasifier

Process Iron Castings

Core Making Cold Box Warm Box amp Shell The core is a chemically bonded sand shape that creates the interior surfaces of an iron casting A core box is the tooling used to create the core Highquality cores are essential to the iron casting process At Waupaca Foundry we have the ability to design and manufacture custom core machines

How is Wrought Iron Made History of Steel Carolina

The process of making the various kinds of iron and steel is described below The difference between iron and steel is based on the amount of carbon contained in the metal If less than 01 carbon is present in the metal it is termed wrought iron and it remains a ductile metal that can be heated and welded but not hardened it can be

Steps in the Modern Steelmaking Process

Aug 21 2020 Ironmaking the first step in making steel involves the raw inputs of iron ore coke and lime being melted in a blast furnace The resulting molten ironalso referred to as hot metalstill contains 445 carbon and other impurities that make it brittle

US4880477A Process of making an austempered ductile iron

An austempered ductile iron alloy with a mixed austeniticbainitic structure is made by a method which enables the iron to withstand high cyclical stresses while having a high resistance to abrasion Articles such as automobile rollerfollower camshafts that are made from the iron alloy may have portions thereof selectively austempered to reduce the overall cost and time required to

Process for making cast iron Armco Inc

More specifically the invention concerns a process for making cast iron of nodular graphite iron and compacted graphite iron types Cast iron usually contains in excess of 25 carbon and upon cooling the cast iron forms either gray iron or white iron When the cast iron is cooled rapidly so that the carbon is retained in a martensitic matrix
