The roller pouring is one of advanced methods of thin metal sheet manufacturing and it is widely used in engineering and other branches of industry. The analysis of influence of speed rates and technological parameters of unit for roller pouring in water-cooled crystallizer (meniscus angle, roller radius, melt overheat temperature) on the condition of metal bar forming from high-strength aluminum alloy with different thickness (2, 3 and 4 mm) was made using methods of mathematical and computing modeling. The series of executed computing experiments allowed to build the analytic dependencies for determination of optimal melt pouring speed under given technological parameters that arranged the solidification of the strips with different thickness on the level of rollers output. For high-strength aluminum alloys there were detected the pouring speeds ranges that determined different conditions of strip forming in inter-roller space and on the level of roller crystallizer output.The obtained results can be used for technology refinement and for choosing balance between technological parameters during roller equipment creation and advancing.
