The invention relates to a short-flow efficient production process of a double-metal composite belt material. The short-flow efficient production process of the double-metal composite belt material comprises the following steps: preparing a high-quality double-metal composite plate blanket with a metallurgical bonding interface by a continuous casting composite process and putting the high-qualitydouble-metal composite plate blanket into a heating furnace to heat; performing multi-pass rolling on the heated plate blanket by a rolling machine, wherein the pass reduction rate of the first passis controlled to be 50 to 70 percent, the pass reduction rate of the subsequent passes is controlled to be 25 to 45 percetn and the total rolling deformation quantity is controlled to be 85 to 95 percent; performing warm rolling forming, wherein the rolling process avoids lubrication; after performing acid-washing treatment, performing rolling forming on a cold-rolling machine, wherein the pass reduction rate is controlled to be 15 to 30 percent, the total rolling deformation quantity is controlled to be less than 90 percent and the rolling speed is 1 to 25 m/min; and performing rapid sensingheating continuous heat treatment on the composite belt material after cold rolling to obtain the double-metal composite belt material. The plate material prepared by the method is short in process flow, high in production efficiency and favorable for realizing large-scale production.
