Problems solved by technology

This method requires special mechanical stirring equipment when preparing semi-solid alloy slurry. The composition of the overall equipment is complicated, and the preparation process is cumbersome. There is no special vertical serpentine runner for casting the alloy liquid, that is, it does not use the serpentine sprue. Sprue to cool the alloy liquid and promote nucleation, just pour the superheated alloy liquid into the stirring crucible smoothly
