Vacuum Metallurgical Equipment
Our electromagnetic stirring (EMS) vacuum precision casting refining furnace is a three-chamber, semi-continuous system integrating high-temperature alloy melting, casting, precision casting, and electromagnetic oscillation. This advanced vacuum refining equipment is primarily used for the melting and precision casting of iron-based, nickel-based superalloys, and other metal materials. It also ensures electromagnetic stirring of the melt to achieve precise mold filling and refined grain structures, enabling continuous and efficient precision casting.
