Abstract

The invention provides a solid-liquid casting-rolling composite equipment for producing net-shaped reinforced interlayer composite materials, which includes an uncoiler, a steering roll, a metal liquid pouring device and a casting-rolling machine. The molten metal pouring device includes a first pouring unit for containing the first molten metal and a second pouring unit for containing the second molten metal, the first pouring unit and the second pouring unit are respectively arranged in parallel on the mesh material on both sides. The present invention also provides a continuous casting-rolling composite method for manufacturing net-shaped reinforced interlayer composite materials. By feeding the net-like materials with surface pretreatment into the casting-rolling area, the surface The combination of processing technology, rapid solidification technology and rolling compounding technology realizes reliable compounding of the interface, which has the advantages of short manufacturing process, high efficiency, low cost and rich product types.

Description

technical field [0001] The invention relates to a production equipment and method of a network-shaped reinforced interlayer composite material, in particular to equipment and a method for producing a network-shaped reinforced sandwich composite material by a solid-liquid casting-rolling composite method. Background technique [0002] With the development of modern science and technology, the requirements for the use of metal materials are no longer limited to a single mechanical property, but require metal materials to have comprehensive characteristics of structure and function under multi-field or even extreme service conditions. Fiber-reinforced metal matrix composites Came into being. Fiber reinforcement methods are mainly divided into two types: network overall reinforcement and short fiber dispersion reinforcement. At present, the problem of controlling the uniformity of short fiber reinforcement dispersed in the matrix has not been completely solved, and the network ...
