Description

technical field [0001] The invention relates to the technical field of casting material preparation, in particular to a high-strength casting material and a preparation process thereof. Background technique [0002] Casting refers to the processing method of melting solid metal into liquid and pouring it into a mold of a specific shape, and waiting for it to solidify and form. The metals to be cast include: copper, iron, aluminum, tin, lead, etc. The common casting materials are raw sand, clay, water glass, resin and other auxiliary materials. Special casting molds include: investment casting, lost foam casting, metal casting, ceramic casting, etc. [0003] The output shaft of the motor is an extremely important internal part. The output shaft is the shaft for outputting power and is an important part of power transmission. At present, the casting materials of the output shaft of the motor are not perfect enough. Abrasiveness, high thermal fatigue strength and toughness ne...
