When the metal had cooled and hardened, the smaller ingots (the "pigs") were simply broken from the runner (the "sow"), hence the name "pig iron". The phase transition of the iron into liquid in the furnace was an avoided phenomenon, as decarburizing the pig iron into steel was an extremely tedious process using medieval technology. In general, melting is a phase change of a substance from the solid to the liquid phase.The melting point of a substance is the temperature at which this phase change occurs. IndiaMART. ISBN 978-1-4000-4760-4.Gaskell, David R. (1995). It is a semi-fused mass of iron with fibrous slag inclusions (up to 2% by weight), which gives it a "grain" resembling wood that is visible when it is etched or bent to the point of failure. Pig iron can be regarded as an impure form of cast iron and it is the raw material for practically all iron and steel products. The added limestone fuses with these components and lowers their melting point, making it easier to separate them from the iron and recover them. CI can also be produced directly from the molten pig iron. Among the advan- The thermal conductivity of iron (not pig iron) is 80 W/(m.K). These are high purity pig irons and depending on the grade of ductile iron being produced these pig irons may be low in the elements silicon, manganese, sulfur and phosphorus. [4] As pig iron is intended for remelting, the uneven size of the ingots and the inclusion of small amounts of sand caused only insignificant problems considering the ease of casting and handling them.
