Abstract

The invention discloses a manufacturing technique for a composite board and belongs to the technical field of composite metal strip rolling. The manufacturing technique comprises the following steps implemented successively: joint surface machining, end surface machining, press fit, blank assembly, vacuum pumping and inert gases filling, heating, hot rolling and verifying. By means of the manufacturing technique, the machining accuracy is improved, and volume production of carbon steel-stainless steel composite boards is achieved; simultaneously, air in a combination blank is replaced through vacuum pumping and inert gases filling, oxidization of interfaces of the combination blank is prevented in a subsequent heating process, a little of residual air between the composite interface and two layers of stainless steel interfaces can be squeezed into an air storage bag gradually along with the moving of a roller and the composite blank simultaneously, and the residual air is prevented from expelling a separating agent or oxidizing the composite interfaces, accordingly, the joint of the finished composite slab is improved effectively, and the quality of the composite slab is further improved.

Description

technical field [0001] The invention belongs to the technical field of metal composite strip rolling, and in particular relates to a composite plate production process and production equipment. Background technique [0002] Composite panels are composite panels made of carbon steel or low alloy steel as the base layer and stainless steel as the cladding. It has both good corrosion resistance and low cost, so it is widely used in petroleum, chemical, salt, water conservancy Electric power, food processing and other fields. [0003] At present, the preparation of composite panels is mainly based on the explosion method. The huge energy generated by the explosion of explosives is used to drive two metal plates to collide at a high speed for welding. The explosion method can realize the composite of metals with widely different properties, but the productivity, yield and The dimensional accuracy is low and the environmental pollution is serious. [0004] With the development o...
