Isolator material is refractory material, and built-in framework of steel reinforcement, length is less than crystallizer.
A kind of composition metal continuous cast method, it is characterised in that include the following steps：
1) isolator is heated to 700~1300 DEG C, is installed along on conticaster with crystallizer；
2) parent metal liquid and composite metal-liquid are injected separately into the parent metal liquid holding groove of tundish and compound simultaneously Molten metal holding groove；
3) parent metal liquid and composite metal-liquid are respectively from parent metal liquid long nozzle and composite metal-liquid long nozzle, simultaneously Inject parent metal liquid cast gate and composite metal-liquid cast gate；Dummy bar seals crystalliser feet；
4) the cooled solidification crust of the composite metal-liquid contacted with crystallizer inner wall, when pulling out crystallizer by dummy bar with every It is partially in semisolid from device contact；
5) the parent metal liquid of injection isolator does not solidify, after leaving isolator with dummy bar, parent metal liquid with it is multiple The semisolid part of alloy category scull inner layer contacts, and its part is melted, and forms mixed layer；
6) with strand downlink, under the action of cooling system, green shell continues to solidify, until strand all solidifies, realizes The metallurgical melting of parent metal and composition metal obtains metallurgical melting composite metal blank.
Beneficial effects of the present invention：(1) parent metal realizes metallurgical compound, binder course truly with composition metal Intensity is high；(2) mixed layer is had between parent metal and composition metal, it can be achieved that composite layer is conducive to the gradual transition of substrate performance The quality control of the operation of rolling；(3) the mixing layer thickness between parent metal and composition metal is controllable, is conducive to composition metal material Amount control；(4) it is not only suitable for plank and is suitable for wire rod again；(5) liquid metal direct combination is cast, without metallurgical compound in order to realize It heats again, efficiently and saves the energy.
