Abstract

The invention relates to a device for manufacturing a composite or slurry and a using method of the device, in particular to a device for manufacturing a metal matrix composite or semisolid slurry and a using method of the device. The technical problems that in the process of manufacturing the metal matrix composite or the semisolid slurry through an existing stirring casting method, heat corrosion happens to a stirring bar in the stirring process, so that the service life of the stirring bar is short, impurity elements are introduced in materials, the purity of the materials is influenced, and it is difficult to manufacture the composite of a large size through the stirring bar are solved. The device is composed of a container end cover, a heating element, a smelting container, an ultrasonic device, a thermocouple, a valve switch, a discharge channel, a rotary device, a device supporting structure, a material collecting container, a transmission device, a device shell, side wall ribs, bottom ribs, a motor and a speed reducer. The device is applied to the field of manufacturing the composite or the slurry.

Description

technical field [0001] The present invention relates to a device for preparing composite material or slurry and a method for its use. Background technique [0002] Metal matrix composites are composite materials that use metal or alloy as the matrix and fibers, whiskers, particles, etc. as reinforcements. Through reasonable design and composite process, it has the advantages of good plastic toughness and processability of metal, high specific strength and specific rigidity of reinforcement, better thermal conductivity, wear resistance and dimensional stability. In the early research and development of metal matrix composite materials, the demand for military technology such as aviation, spaceflight, and weapons played a huge role in promoting. Provide a broader application prospect. [0003] According to the addition method of reinforcement, the preparation method of metal matrix composites can be divided into external method and in situ reaction method. The external addi...
