Description

technical field [0001] The invention relates to the technical field of electromagnetic casting, in particular to an aluminum silicon carbide differential pressure electromagnetic casting equipment. Background technique [0002] Aluminum silicon carbide composites have a wide range of applications in electronic packaging, aerospace, military and automotive fields due to their high strength, modulus and thermal conductivity, as well as low thermal expansion coefficient and other performance advantages. Due to the poor wettability between silicon carbide and aluminum melt, aluminum melt cannot spontaneously infiltrate into the porous silicon carbide preform, so the preparation of aluminum-silicon carbide composites currently mainly relies on pressure casting. By utilizing mechanical pressure or differential pressure, a driving force is provided for the infiltration and filling of the aluminum melt in the silicon carbide porous preform. [0003] However, the pressure required b...
