PURPOSE:To provide mold for continuous casting of steel which prevents the attenuation in magnetic flux during electromagnetic agitation by using nonmagnetic metals (alloys) having resistivity higher than that of copper. CONSTITUTION:A mold for continuous casting of steel is constituted of nonmagnetic metals or alloys having resistivity higher than that of copper, for example, steel contg. Al, Cr, Mo, Ti, V, W, etc. In the stage of agitating the molten steel in such mold by electromagnetic forces, large-scale frequency converters and the like are not required, unlike with conventional copper molds, and it is possible to prevent the attenuation of magnetic flux and to use electric current of commercial frequencies as the current to be flowed to electromagnetic coils. |
