摘要： It regards alloys, in particular steel, that are paramagnetic around the liquidus temperature with an aim to support formation of columnar grains, suppression of forming polyhedral grains, refining a primary structure and targeted intervention into formation and distribution of primary and accompanying structural components. The process control is applied in the entire molten metal volume that solidifies under the effect of linear magnetic field having induction of 0.04 to 03 T. The process control of the solidification of continuously cast steel is applied in the entire molten metal volume, magnetically treated molten metal is transported into from the active zone of an electromagnet generating linear magnetic field having induction of 0.04 to 03 T by transportation motion during 5 to 10 seconds with velocity of 0.1 to 0.6 m.s -1 , wherein motion of the magnetically treated molten metal may be produced in any manner, in particular by a linear motor or conductively, by interaction of magnetic field of the electromagnet and direct current of 500 to 2200 A separately conducted into a billet by rollers closely below a crystalliser and by rollers below the electromagnet.
