Problems solved by technology

However, since the core material casting composite method still does not solve the interface problem, when the outer layer of the composite material is solidified, gas and impurities are easy to accumulate at the interface, which affects the product quality, and the process is complicated, the technology is difficult, the production cost is high, and the scope of application Narrow, only suitable for the preparation of clad composites, not suitable for the preparation of gradient layered metal composites, laminated metal composites

Abstract

The present invention discloses a technique and relative equipment for casting laminated and composite metal material. Target material is heated to 300 DEG C to 1200 DEG C by an electromagnetic induction heater installed on exterior of a casting die or a water cooling crystallizer. Molten electroslag liquid is poured in the casting die or the water cooling crystallizer, and an electrode is inserted in for heating. The metal liquid is poured in the casting die or the water cooling crystallizer by top casting mode or bottom casting mode. After casting, the induction heater and the electrode conduct continuous heating for 3 to 20 minutes, then heating is stopped, and layered composite material with plane gradient, laminated composite material and coated composite material of all geometric shapes can be produced. The present invention can simplify production procedures of composite material and can realize the dynamic regulation of all technical parameters during composition. The interface of the composite layer is under eay control so as to achieve excelllent metallurgical combination. The present invention has wide optional range about materal of the composite layer, high productivity, simple production technique and low cost.

Description

technical field [0001] The invention belongs to layered metal composite materials, and the technical field mainly relates to a process and equipment for manufacturing metal layered composite materials by casting method. Background technique [0002] Laminated metal composite materials are various double-layer metal composite materials prepared by using various composite technologies to combine two or more metal materials with different physical, chemical and mechanical properties in layers to achieve firm metallurgical bonding at the interface. Layer or multi-layer gradient layered composite materials, laminated composite materials and coated layered composite materials, although the prepared composite materials still maintain their original characteristics, their physical, chemical and mechanical properties are relatively single The metal material is much superior, so that different parts of the material have different properties, so as to overcome the respective shortcomin...
