Cast iron is basically an alloy of iron and carbon and is obtained by re melting pig iron with coke limestone and steel scrap in a furnace known as cupola The carbon content in cast iron varies from 17 to 667 It also contains small amounts of silicon manganese phosphorus and sulphur in form of impurities elementsMaking iron Conversion to steeThe basic raw material for steel manufacture is either the hot metal from the blast furnace steel scrap or a mixture of bothThe proportions of material used vary according to the process and the type of steel required

The raw materials are melted at an extremely high temperature in a large cauldron called a creuset in French and then poured into the moulds Once the shape is cast and the iron cooled it is removed from the mould ready for the finishing process to beginBy observing the table and subsequent graph the process that seems to be have the greatest CO2 impact and largest tax is the actual iron manufacturing or the production phase This result makes sense as the iron manufacturing process utilizes other sectors of the economy that have high environmental impacts Production

Wrought Iron and its manufacturing process Cast Iron Pig iron alongside scrap iron coke and limestone is liquefied in a vertical furnace called cupola Here likewise the carbon and different impurities introduce oxidize in nearness of a little measure of air to shape slag The liquid iron got from dome heater can be thrown into formsaccount for more than 90 of the world production of iron and steel powders viz the Höganäs sponge iron process and the water atomizing process The former process is based on reduction of iron ore yielding a highly porous sponge iron which subsequently is comminuted to powder The latter process is based on atomization of a stream of liquid

Manufacturing Process of Cast Iron Castings The making of cast iron begins with a combination of raw materials Iron is rarely found in its pure form Only meteorites contain pure iron The iron in use for centuries is found in the combination of iron and other elements These combinations are known as iron The casting process can have a significant effect on the structure and properties of gray iron casting The processes using sand as the mold media have a somewhat similar effect on the rate of solidification of the casting while the permanent mold process has a very marked effect on structure and properti

Iron ore as mined is a combination of iron with oxygen and various other unwanted substances generally known as gangue The first metallurgical step is to reduce iron ore to metallic iron a process which is mostly carried out in a blast furnace using coke as both a fuel and reducing agentThe process starts in the center of the wheel with the three main ingredients of iron in the form of iron ore coke and lime which are fed into a blast furnace to produce molten iron The molten iron is mixed with recycled steel scrap and further processed in a basic oxygen furnace to make steel The electric arc furnace melts recycled steel
