The core of the suspension smelting equipment system is the cold crucible induction suspension smelting technology. The segmented water-cooled crucible is placed in an alternating electromagnetic field, the eddy current generated by the electromagnetic field is used to heat melt the metal, and the electromagnetic force is relied on to keep the molten metal in soft contact with the crucible wall. or non-contact state to realize the technology of furnace smelting; the biggest feature: the material to be melted is in a suspended or quasi-suspended state, which can solve the defects in the existing material production process (unevenness + secondary pollution)
The scientific research projects that Semet has developed and completed include: research on enhancing levitation force, increasing melting temperature, extending crucible life, expanding equipment specifications, improving operating efficiency, improving alloy uniformity, and realizing digital and intelligent operations. Combined with various casting technologies, the technologies that can be realized include bottom casting, tilting and suction casting, centrifugal casting, squeeze casting, continuous ingot pulling, etc. Cold crucible smelting technology combined with gas atomization powder making, directional solidification, zone melting purification, rapid quenching and rapid cooling, etc.
