This article.ls expected to give some additional knowledge as well as to widen the horizon of literary works, especially for the students and lecturers of mechanical Engineering department as well as the metal industry society that are studying the crystallization process of metal, especially cast iron. Based one the result of the author´s library study, there was a close correlation, in the forming the physical and mechanical qualities of a metal. Between the structure of a metal· and the speed of heat changes, thesolidus-iquiditas temperature gradient, the geometry and the substance of the casting mould Equiaxed crystal with a columnar structure in it could be obtained when the speed of cooling off the metal liquid was high while the metal solidification was going on, on the contrary, when the speed of the heat changes was low the metal obtained would have a vague columnar-shape crystal with crystal grains of random oriented polygons. So to contain a high quality metal whit uniform structures the regulation of the heat changes while the metal solidification process is going on should necessarily be carefully done besides paying attention to the factors of solidus - liquidus temperature gradient and the geometry of the casting mould usedKey words : the frame - work parameter, crystallization.
