摘要
介绍了AA7178铝合金的熔铸特点,对该合金的熔铸工艺进行摸索和改进,采用同水平热顶铸造方法,结合已有的技术和经验,有效克服了AA7178铝合金铸造中心裂纹和锯切裂纹,成功试制出Φ250mm AA7178铝合金圆铸锭,确定了合理的熔铸工艺。
Based on the casting characteristics of AA7175 aluminum alloy, the rational melting ＆ casting process of AA7175 aluminum alloy round rod was determined by hot-top casting. The finished product of φ250 mm AA7175 aluminum alloy round rod was successfully produced.
