作者两次去日本考察铸造技术,参观了一些铸造厂。这些广大多是专业化铸造厂,差不多每个厂都有自己的铸造技术特点,力求采用专门的特种铸造技术,生产独具特色的、成本低的铸件产品,增强竞争能力,占领市场,来谋求高额利润。例如采用离心铸造法大量生产球墨铸铁管、铸铁铸钢轧辊;采用负压造型法生产形状不复杂的铸件,如配重、浴缸、建筑构件等;采用连续铸造法生产连续铸棒等等。此文专门介绍所看到的铸铁连续铸棒的生产技术概况。
The author went to Japan to study foundry technology twice and visited some foundries. Most of these are specialized foundries, almost every factory has its own casting technology features, and strive to use special special casting technology, production of unique, low-cost castings products, enhance competitiveness, occupy the market, to seek High profits. For example, mass production of ductile cast iron pipes and cast iron cast steel rolls by centrifugal casting; production of uncomplicated castings such as counterweights, bathtubs and building components by negative pressure molding; continuous cast rods by continuous casting and the like. This article is devoted to the production technology overview of cast iron continuous casting rods.
