Abstract

This study was done to define the casting property of aluminum alloy strip by the melt drag process. Roll speed, roll material, melt-height in the nozzle (roll-molten metal contacting length) and nozzle position for roll were chosen as fundamental formation factor and investigated. Sound strip is cast in the range of 20∼70m/min, and thickness of the strip was 0.5∼1.5mm. Strip thickness can be controlled by roll speed and contacting length between roll and molten metal. Strip thickness increases with decrease of roll speed and increase of roll-molten metal contacting length. Diagram, by which we can estimate the dependence of such fundamental factors as roll speed, melt-height in the nozzle on the thickness and quality of the strip, is drawn. Surface condition and thickness distribution of the cross section of the strip depend on contacting condition between roll and molten metal (strip). Aluminum coating on the roll surface is useful for getting sound contacting condition between roll and molten metal (strip).
