Abstract

The invention discloses a composite preparation process and composite preparation equipment for semisolid metal slurry. A weak electromagnetic stirring device and a mechanical stirring device are compounded together to prepare the semisolid metal slurry. Compared with an existing semisolid metal slurry preparation technique, the compound preparation process has the advantages that 1, compared witha rotary magnetic field electromagnetic stirring method, the electromagnetic field can be fully covered to avoid a skin effect and the needed energy consumption is low; 2, compared with a weak electromagnetic stirring method, the stirring force of alloy slurry is enhanced, the time needed to obtain the semisolid metal slurry is shortened, and the efficiency is improved; 3, compared with a mechanical stirring method, no mechanical stirrers are available, so that the defects that the stirrer is corroded and the alloy slurry is polluted are overcome, and meanwhile, the temperature of the slurryis controllable; 4, the composite preparation equipment is simple in structure, low in cost, flexible to control process and convenient to operate; and 5, the composite preparation process solves theproblem of low preparation efficiency of the semisolid slurry in large structural part production in production of large structural parts, the weights of which are over 5 Kg.

Description

technical field [0001] The invention belongs to the technical field of semi-solid metal processing, and relates to a composite preparation process and equipment for semi-solid metal slurry. Background technique [0002] Semi-solid metal forming technology is an advanced forming method for metal parts that combines the strong fluidity of liquid casting and the high mechanical properties of solid forging. It is known as the green manufacturing process with the most development potential in the 21st century. The technology has gradually realized industrialization, and the key lies in the preparation of high-quality, low-cost metal semi-solid spherical grain materials. [0003] Among all the preparation methods of semi-solid metal materials invented, the electromagnetic stirring method is the earliest method applied in industrial production, and it still occupies a dominant position in the industrial application of semi-solid metal forming. The parameter control of the electrom...
