摘　　要：简要介绍了一种V型干式缸套气缸体铸造工艺,针对缸孔加工后发现的夹渣缺陷进行了分析。通过优化排气溢流系统、提高浇注温度、增强滤渣排渣结构、增加毛坯局部补贴等措施,最终大幅降低缸孔夹渣缺陷率,解决了夹渣问题。The casting process of V-shaped dry cylinder liner cylinder block is briefly introduced,and the slag inclusion defects found after cylinder hole machining are analyzed.By optimizing the exhaust overflow system,raising the pouring temperature,strengthening the filter slag discharging structure,increasing the partial subsidy of blank,etc.,the slag inclusion defect rate of the cylinder hole is greatly reduced and the slag inclusion problem is solved.
