The main aim of studies was to determine common influences of two different refinement methods on EN AW-Al99,5 primary structure and developing of refinement mechanism. The first method is inoculation with small amount of (Ti+B) less than obligatory standard PN-EN 573-3 and the second method is influence of electromagnetic field on aluminium crystallization process. These methods of structure refinement are particularly important in continuous and semi-continuous casting where products are used for plastic forming. Large columnar crystals zone result in forces extrusion rate reduction and during the ingot rolling delamination of external layers can occur.
