Abstract: One can that the indudtry of cast iron foundry manufactures invisible products, no matter what vital, then that they are machined before becoing the components of machines where equipment for all industries. The knowledge of the pig iron and cast iron is not thing simple, complex are the phenomena which accompany, as well solidification as cooling in a solid state such alloys and complex also are the effects, on the pace of the solid product cold. Various components elements the castiron and can obstained satisfactory results, only the founders who inculed/understand prefectly, which occurs in the mould. The addition of alloy element suitable in the pig iron and cast iron makes it possible to modify the structure and to still improve the mechanical, physical characteristics...etc. Thus, one goes, one studied the influence of the mechanical properties and the distribution of the elements between the structural components according to the section of the cylinders at the speed of their cooling.
