铝合金铸造工艺过程中,合金熔炼质量的好坏,是影响铸件质量的首要因素.因此,在解决铸件的技术质量关键中,必须特别注意合金的熔炼质量,不断总结经验,掌握规律,使铸件质量稳定下来.在熔炼工艺定型以后, In the process of aluminum alloy casting, the quality of the alloy is the primary factor that affects the quality of the castings.Therefore, in the key to solve the technical quality of the castings, we must pay special attention to the quality of the alloy smelting, continue to sum up experience, master the law, The quality is stable.After smelting process stereotypes,
