据估计,1985年内燃机铸件产量约占全国铸件产量的1/10,其中球铁占全国球铁产量的1/4,可见内燃机铸造行业在全国铸造行业中占有重要的位置。内燃机中铸件占整机重的80％,因此铸造是内燃机行业的基础,是内燃机行业的身躯。内燃机铸件结构复杂,主要零件如缸体、缸盖、曲轴等在高速、高温、高压下工作,要求铸件内外在质量高,工作可靠,耐久性好。内燃机铸造技术水平,特别是在大量流水生产中往往代表一个国家铸造生产技术及相关材料工业和铸造技术装备工业的发展水平。建国35年来,我国内燃机铸造生产有很大的发展,工艺技术和装备,铸件质量都不断提高,少数工厂的工艺和装备水平以及铸件质量可接近国际先进水平。但是整个内燃机铸造行业目前大约相当于国际五、六十年代水平,相当多的工厂只相当于国际三、四 It is estimated that in 1985, the output of internal combustion engine castings accounted for about 1/10 of the national output of castings, of which ductile iron accounted for 1/4 of the national ductile iron production. This shows that the internal combustion engine foundry industry occupies an important position in the national foundry industry. The internal combustion engine castings account for 80% of the weight of the whole machine, so the foundry is the foundation of the internal combustion engine industry and the internal combustion engine industry body. The structure of the internal combustion engine casting is complex. The main parts such as cylinder block, cylinder head and crankshaft work under high speed, high temperature and high pressure. The internal and external requirements of the casting are of high quality, reliable work and good durability. The level of internal combustion engine casting technology, especially in a large number of running water production often represents a country casting production technology and related materials industry and casting technology and equipment industry level of development. In the 35 years since the founding of the People’s Republic of China, great progress has been made in the foundry production of internal combustion engines in our country. The technology and equipment, the quality of castings are constantly improving. The craftsmanship and equipment level of a few factories and the quality of castings can be approached to the international advanced level. However, the entire internal combustion engine foundry industry is currently equivalent to the world’s five or six decades, a considerable number of factories is only equivalent to international three, four
