Abstract

The invention particularly relates to a device and method for double-stream-pouring continuous casting of a multilayer metal plate. The device is provided with a first heat preserving furnace, a second heat preserving furnace, a first crystallizer, a second crystallizer, a first drainage bar and a second drainage bar. The bottom end of the first heat preserving furnace is connected with the first crystallizer. The bottom end of the second heat preserving furnace is connected with the second crystallizer. The first crystallizer is connected with the second crystallizer. The width of the first drainage bar is equal to that of the second drainage bar. The first drainage bar is located below the second drainage bar and is tightly attached to the second drainage bar. The first drainage bar and the second drainage bar penetrate into the bottom end of the second crystallizer commonly. The first drainage bar penetrates into the bottom end of the first crystallizer. The first drainage bar and the second drainage bar are connected with a traction mechanism. By means of the device and method for double-stream-pouring continuous casting of the multilayer metal plate, the production processes of the compound plate are obviously reduced, the production period is shortened, the material utilization rate is increased, the compound plate lower in manufacturing cost can be produced, meanwhile the combining strength of a compound face and the like is effectively improved, and the reliability of finished products is improved.

Description

technical field [0001] The invention relates to a manufacturing technology of a clad metal sheet, in particular to a device and method for double-strand continuous casting of a clad metal sheet. Background technique [0002] In the field of electrical contacts, the internal oxidation process is a common process for manufacturing silver metal oxide contacts. Among them, the sheet contacts used in electrical appliances such as AC contactors need to be assembled with copper contact bridges after welding, while silver metal oxides The wettability between the material and the solder and the copper contact bridge is not good, and it is not easy to weld, so a pure silver layer should be added on the welding surface of the silver metal oxide sheet contact to facilitate welding, and the thickness distribution of the silver layer is required As uniform as possible, there is a relatively clear boundary between the silver metal oxide layer and the silver layer. Internal Oxidation Silve...
