Abstract
Two-pole rotary field type electromagnetic stirring was applied in the secondary cooling zone in order to reduce center-line segregation of continuously cast high carbon steel billets.
The results obtained are summarized as follows.
(1) A homogeneous macrostructure of equi-axial crystals are obtained by the stirring.
(2) It is proved that the stirring is more effective at higher casting temperatures, by a statistical method which is presented to accurately evaluate the degree of center-line segregation of continuously cast billets.
(3) Tensile properties of products, PC wire, are improved by the stirring.
