Semi-solid slurrying device and composite board manufacturing device using semi-solid slurrying device

Abstract

The invention relates to the technical field of semi-solid slurrying, in particular to a semi-solid slurrying device and a composite board manufacturing device using the semi-solid slurrying device. The semi-solid slurrying device comprises a runner communicated with a liquid storage tank, obliquely arranged from top to bottom and used for molten metal to flow through, wherein the runner is provided with the contact surface in contact with the molten metal, strip-shaped protrusions parallelly distributed from top to bottom are arranged on the contact surface, grooves are formed among adjacent strip-shaped protrusions, the length directions of the strip-shaped protrusions are perpendicular to the flowing direction of the molten metal. By adopting the semi-solid slurrying device, the kish problem of the contact surface of the runner is greatly solved, high-quality semi-solid slurry produced by the semi-solid slurrying device can form metallurgical bonding with a solid heterogeneous material, and further the technical problem that interface metallurgical bonding is difficult to achieve by adopting a traditional composite board manufacturing process is further effectively overcome.

Description

technical field [0001] The invention relates to the technical field of semi-solid pulping, in particular to a semi-solid pulping device and composite board preparation equipment using the device. Background technique [0002] Due to resource constraints and the need for material properties, layered composites with good properties (such as copper / aluminum, steel / aluminum) have become the goal of domestic and foreign scholars. Semi-solid processing technology is between solid-state processing and liquid processing, and has its unique advantages, such as reducing energy consumption and cost, improving product quality and performance, etc. After research, the semi-solid-solid preparation technology can prepare bimetallic composite materials with good metallurgical bonding, and the rapid preparation of high-quality semi-solid slurry is the premise and key of composite forming, but so far there is still no suitable semi-solid-solid bimetallic composite material. Metal composite s...
