The shortcomings of this process are: vacuuming needs to be heated at 400~450°C, which is time-consuming and energy-consuming; when the composite surface and the high-temperature anti-adhesive agent are in the same sealed space, the high-temperature anti-adhesive agent will be produced when the composite billet is heated in the heating furnace. Harmful gas pollutes the surface to be compounded, resulting in partial non-fitting of the edges. At the same time, due to the existence of gas, the billet is prone to bulging, and the gas moves during rolling to destroy the release agent. Surface Quality

Abstract
The invention provides a production method for a vacuum-rolling layered metal composite board. The high-performance layered composite board is obtained through the steps of blanking of a base plate and a cover plate, drilling a blind hole and a through hole on the base plate, welding a transmission joint, welding a breather pipe, assembling the cover plate, painting separant, sealing welding the periphery of the cover plate, sealing welding the periphery of a billet, drilling a vacuum hole, vacuumizing, rolling and the like. The space in a compound billet is divided into two spaces through the method of the transmission joint, one space is communicated with the outside world, the high-temperature separant is in the space, so that the gas generated by the separant when the compound billet is heated is exhausted to avoid bulging, and the quality of the surface of a covering layer is improved; the other space is a vacuum space, a face to be compounded is in the space, and the face to be compounded is in a vacuum space alone, so that the face to be compounded is not prone to be polluted during the heating and rolling process, and the generation of unbinding at the edge of the face to be compounded is avoided. According to the production method, heating is not needed, high efficiency, energy consumption and environmental protection are possessed, and the layered composite board with high bonding intensity can be produced.
Description
Technical field: [0001] The patent of the invention relates to a production method of a layered metal composite plate with stainless steel, titanium alloy and nickel-based alloy as cladding metal, and ordinary carbon steel and stainless steel as base metal. technical background: [0002] Layered metal composite panel is a new type of material formed by compounding two or more metals. It has physical, chemical and mechanical properties that single-layer metal materials do not have. Fatigue, dimensional stability, wear resistance, vibration resistance and other performance requirements, while greatly saving rare and precious materials, reducing costs, has been widely used in chemical industry, electric power, machinery, ships, aviation and other fields. [0003] At present, the production of layered metal composite panels mainly adopts the method of explosive welding, explosive welding + rolling or rolling. Among them, the two production methods of explosive welding and explo...
