Abstract

The invention discloses an immiscible alloy preparation method and continuous casting device. An immiscible alloy is composed of a metal A and a metal B, and the melting point of the A metal is lowerthan the melting point of the metal B. The preparation method comprises the following steps that the A metal is heated to Ta and then is subjected to heat preserving to obtain A melt, the B metal is heated to Tb and then is subjected to heat preserving to obtain B melt, wherein the Ta is less than the Tb; and after the A melt and the B melt are uniformly mixed through electromagnetic stirring, themixture enters a continuous casting water cooling crystallizer to be rapidly solidified to prepare the immiscible alloy. The immiscible alloy prepared by the method is large in specification range, good in surface quality, internally free of macroscopic segregation, free of air holes, free of cracks such as loosening, uniform in composition and fine in tissue, and has the advantages of simple devices, high production efficiency, low cost, suitability for industrial scale production and the like.

Description

technical field [0001] The invention belongs to the technical field of preparation of immiscible alloy materials, and in particular relates to a preparation method and continuous casting equipment of an immiscible alloy. Background technique [0002] Immiscible alloys have many excellent physical properties, such as high strength, good electrical and thermal conductivity, and magnetic properties. Therefore, this type of alloy has broad application prospects in permanent magnets, high-performance electrodes, and electrical contact materials. Since immiscible metals have an immiscible zone during the solidification process, when the solidification temperature passes through this zone, two liquid phases with different components will be separated in the alloy liquid. The density difference of the two liquid phases makes the alloy easily form macro-segregation in the gravitational field. [0003] In order to solve the above-mentioned macro segregation and other problems, vario...
