一、概况:我厂482F 风冷汽油机的汽缸体为了保证冷却效果,是用铝合金一铸铁双金属铸造,就是要求耐磨的汽缸体的内腔是由合金耐磨铸铁铸造的,而要求散热快的叶片则由铝合金铸造的(图1)。其合金耐磨铸铁及铝合金成份和性能要求如下: First, an overview: I plant 482F air-cooled gasoline engine block in order to ensure the cooling effect is cast with a cast aluminum bimetal, is required wear-resistant cylinder cavity is cast from alloy wear-resistant cast iron, and require cooling Fast blades are cast from aluminum (Figure 1). Its alloy wear-resistant cast iron and aluminum alloy composition and performance requirements are as follows:
