Problems solved by technology

[0006] The invention provides a high-permeability soft-contact two-stage copper alloy crystallizer and its preparation and application. The method is based on the principle of "more quantity and less element". The soft contact electromagnetic extrusion force has developed a copper alloy with higher magnetic permeability. The magnetic permeability of the new high-permeability copper alloy is 4 times that of traditional pure copper materials; in view of the problem of insufficient joint strength at the mold weld, the The welding groove angle of the upper half and the lower half of the crystallizer is spe

Abstract

The invention relates to a high-transmission soft contact two-section type copper alloy crystallizer as well as preparation and application thereof, and belongs to the field of electromagnetic metallurgy equipment manufacturing. The crystallizer uses copper alloy ingredients in percentage by mass: less than 0.5 percent of Al, 31 to 33 percent of Mn, less than 0.5 percent of Ti, less than 0.5 percent of Si and the balance of Cu. The crystallizer comprises a crystallizer upper half section prepared by the copper ally, and a crystallizer lower half section prepared from pure copper, wherein the connecting position of the crystallizer upper half section and the crystallizer lower half section is welded by pure copper TIG; the welding mode is a V-shaped big slope opening forming mode; the thorough welding is ensured; in addition, the welding seam welding position is enabled to have the sufficient intensity; the soft contact electromagnetic power is provided by an electromagnetic induction coil surrounded on the outer side of the upper half section of the obtained high-transmission magnetic soft contact two-section type copper alloy crystallizer; the best power supply work parameter is given; the guidance is provided for the optimization production. The cooling effect of the crystallizer is identical to the cooling effect of a conventional pure copper crystallizer; the inherent attribute of the steel liquid initial stage solidification can be enhanced by the crystallizer.
