The company has developed a lightweight short process process and method for aluminum alloy wheels. The process flow is: smelting preheating, low pressure casting heat treatment cooling, processing and cleaning, the first drying and coating treatment? The second drying; smelting: aluminum alloy material Put it into a hot air and water-cooled cupola for melting; preheating, low pressure casting: first, preheat the mold, and spray the mold after the preheating treatment. The spraying thickness is 100~200 mm. Die casting; heat treatment: heat treatment of the aluminum alloy wheels after low pressure casting. The aluminum alloy wheel lightweight short-process process and method can avoid the effects of sticking aluminum and heat preservation by spraying the mold, fully improve the mechanical properties of the casting, improve the cutting performance of the alloy, etc., and can eliminate segregation and heat preservation through the heat treatment process. Needle-like structure, improve the structure and mechanical properties of the alloy.
