Synopsis : In order to improve the inner quality of continuous casting bloom, especially for the increase of the ratio of the equiaxed crystal zone and the reduction of center segregation and center porosity, a study was made of the application of the stirrer (Direct Current and Static Magnetic Field Method) to the bloom caster. From experiments in the laboratory and at a 300 •~ 400 m/m bloom caster, the following results were obtained, (1) The ratio of the equiaxed crystal zone increased when long stirring time with low stirring force was applied. (2) The degree of white band was related to the maximum stirring force and was not influenced by the stirring time. A direct current and static magnetic field method was suitable to the bloom caster. Application of the stirrer to the 300 •~ 400 m/m Caster made it possible to improve the inner quality of the cast bloom and to expand the applications of caster products.
