titleOfInvention | Preparation method and application of ultrahigh-purity cobalt plate with controllable structure |
abstract | The invention discloses a preparation method and application of an ultra-pure cobalt plate with controllable structure, wherein the preparation method comprises the following steps: cold press molding, high-vacuum degree vertical melting, a high-vacuum degree electron beam smelting furnace, an argon chamber stainless steel sheath, three-dimensional high-speed isothermal hot forging cogging with gate forging deformation and total deformation cooperatively controlled, angle-variable cross control rolling and heat treatment, turning, packaging and the like, wherein the purity of the prepared ultra-high pure cobalt is more than or equal to 99.995%, the average grain size is 10-40 mu m, the content of beta-Co of an fcc structure in the plate exceeds 50%, the magnetic permeability is more than 70%, and the magnetic permeability nonuniformity is less than 1%. The preparation method designed by the invention can effectively control the grain size and grain size distribution of the finished product and regulate the tissue distribution of the finished product, thereby providing a raw material guarantee for the finished product to be used as a high-quality target material. |
