Problems solved by technology

However, this method also needs special mechanical stirring equipment when preparing semi-solid metal slurry. The composition of the overall equipment is complicated, and the preparation process is relatively troublesome. There is no special oblique straight composite pipe channel for pouring the molten metal, that is, it does not use oblique Straight composite tube channel to cool the metal liquid and promote nucleation, just pour the superheated metal liquid into the stirring crucible smoothly
