Description

technical field [0001] The invention belongs to the technical field of metal processing. Background technique [0002] Semi-solid metal processing is currently a research hotspot in the field of material processing. It has the characteristics of high quality, high efficiency, low cost, cleanliness and agility. It is called "the most promising near-net shape technology in the 21st century" by many famous experts at home and abroad. The primary solid phase of the semi-solid metal slurry is similar to a spherical shape. Under the action of high-speed shearing, the viscosity of the metal melt is greatly reduced, and the fluidity is greatly improved. It can form various castings with very complex shapes. The internal microstructure of the formed castings is relatively ordinary. It is finer, more uniform in distribution, and the internal density becomes higher, so the mechanical properties of semi-solid processed parts are greatly improved. For this reason, many experts at home a...

Problems solved by technology

For this reason, many experts at home and abroad have carried out a large number of experiments and theoretical researches, developed many new processes and new devices for the preparation of different types of semi-solid slurries, and successfully prepared high-quality semi-solid slurries, and obtained many orders. It is a gratifying achievement, but it has not made great breakthroughs in the promotion of industrial applications and the production of large-scale parts. The key reason is that the automation of the production process is not high, and it is difficult to achieve precise control of the core process parameters. , the instability of the process, the connection with existing equipment and the high cost, etc., all restrict the practical application of semi-solid technology and become a stumbling block for the industrialization of semi-solid processing
