Cast Iron - an overview ScienceDirect Topics

Cast iron was the earliest metallic material to be used structurally (from around 1780),and many examples of its use are still in service today.Cast iron girders were often used to support brick jack arch infill (Fig.1.1) so as to form a bridge deck or the floor of a large building.Cast iron columns were used in both buildings and bridge piers.Cast Iron Metallurgy BritannicaCast iron metallurgy Britannica Cast iron Cast iron,an alloy of iron that contains 2 to 4 percent carbon,along with varying amounts of silicon and manganese and traces of impurities such as sulfur and phosphorus.get price Midrex Process for Direct Cast Iron Metallurgy for DummiesCast Iron.Cast iron is derived from pig iron,and while it usually refers to gray iron,it also identifies a large group of ferrous alloys which solidify with a eutectic.The colour of a fractured surface can be used to identify an alloy.White cast iron is named after its white surface when fractured,due to its carbide impurities which allow cracks to pass straight through.

Cast Irons Composition and Properties Alloys Iron

Cast irons are iron-carbon (and silicon) alloys having carbon or carbon equivalent value,more than 2% (actually it is 2.1 1%),i.e.,more than the maximum solid solubility of carbon in austenite such that the eutectic reaction occurs during solidification.As the higher carbon contents make them more brittle,industrial cast irons have carbon normally in the range of 2.11 to 4% and silicon 0.5 to 3% (along-withCast iron Wikipedia Republished // WIKI 2ProductionTypesHistorySee AlsoFurther ReadingExternal LinksCast iron is made from pigiron,which is the prod­uct of melt­ing iron ore in a blastfur­nace.Cast iron can be made di­rectly from the molten pig iron or by re-melt­ing pigiron,often along with sub­stan­tial quan­ti­ties of iron,steel,lime­stone,car­bon (coke) and tak­ing var­i­ous steps to re­move un­de­sir­able con­t­a­m­i­nants.Phos­pho­rus and sul­fur may be burnt out of the molten iron,but this also burns out the car­bon,which must be re­placed.De­peSee more on wiki2History_of_ferrous_metallurgy - chemeuropeEastern MediterraneanChinaEuropeThe Transition to Coke in EnglandHot BlastIndustrial SteelmakingSee AlsoReferencesAbout 1500 BC,increasing numbers of smelted iron objects (distinguishable from meteoric iron by the lack of nickel in the product) appear in Mesopotamia,Anatolia,and Egypt.During the Early Iron Age (12th to 10th centuries BCE) iron came to replace bronze as the dominant metal used for tools and weapons across the Eastern Mediterranean (the Levant,Cyprus,Greece,Crete,Anatolia,and Egypt).Although iron objects are known from the Bronze Age across the Eastern Mediterranean,they occur only sporadicallSee more on chemeuropeRelated searches for cast iron metallurgy britannicacast iron metallurgymetallurgy of iron and steelductile iron metallurgySome results are removed in response to a notice of local law requirement.For more information,please see here.12345NextCast iron metallurgy BritannicaCast iron,an alloy of iron that contains 2 to 4 percent carbon,along with varying amounts of silicon and manganese and traces of impurities such as sulfur and phosphorus.It is made by reducing iron ore in a blast furnace.The liquid iron is cast,or poured and hardened,into crude ingots called pigs,and the pigs are subsequently remelted along with scrap and alloying elements in cupola furnaces and recast into
