Abstract
The present invention relates to a liquid-solid rolling bonding method for heterogeneous metals and an apparatus therefor. The method comprises: pouring a liquid metal onto the surface of a heterogeneous solid base metal coated with a soldering flux; rolling the liquid metal and the solid metal under pressure; solidifying the liquid metal and making it bond to the surface of the solid base metal under rapid cooling to realize metallurgical bonding of the two or more metals. The apparatus comprises an unrolling machine, a soldering flux tank, a drying-heating apparatus, a pouring nozzle, an interior water-cooling rollers and a roll-collecting machine arranged in order, a pouring basket is disposed above the pouring nozzle and a base frame is disposed below the pouring nozzle. The present invention has the advantages of high bonding strength, lower production cost, high production efficiency, good product quality, fewer investment for the apparatus and lower consumption of energy. The method of the present invention can replace the convention rolling bonding method in solid-solid phase and is suitable for the production of various clad metal sheets and strip.
