Formation of the structure of sheet blanks during roll casting of metals

The physical modeling method was used to study the processes of formation structure sheet blanks during ingotless casting-rolling metals. At same time, on basis theoretical analysis, main parameters are determined, with help which it is possible effectively control crystallization and blanks. studies carried out made establish regularities influence hydrodynamic thermophysical conditions pouring metal (the speed nature movement in inter-roll space, overheating temperature melt intensity heat removal from it) its formation. A transparent organic alloy camphene (C10H16) as a medium, makes visually these rolling Due transparency camphene, transformation blank at different stages clearly studied: rough primary crusts solidifying rolls, due their partial deformation zone, passes into fine-grained upon exiting it. dependence linear rate exchange roller mold shown. optimal ranges values ensure stability process roll casting results obtained were for development practical recommendations real metals, particular aluminum alloys various grades.
