我在美国进修期间,参观了一些铸造车间及研究所,了解到美国铸造行业的一般情况。这里,仅以已粗浅之见,向读者们作一介绍。一、工厂的一般情况为了使读者有一个概括的了解,我将工厂的水平分为中等、较先进、较落后三种。 1、中等水平工厂的情况①Wisconsin州某铸造厂主要生产质量要求较高的中、大型铸件,如泵体、阀门,大齿轮等。大部分产品用在汽轮机、飞机及潜艇上。铸件的材质主要是高级铸铁、镍基及铜基合金。该厂起始于1912年,厂房规模较大,设备基本上是六十年代的水平。理化检验的仪器设备齐全,有X射线,荧光分析、光谱分析、计算机作数据处理,还有力学实验 During my fellowship in the United States, I visited some foundry shops and research institutes to learn about the general situation of the foundry industry in the United States. Here, only to the superficial view, to the readers to make an introduction. First, the factory’s general situation In order to give readers a general understanding of the level of the factory I divided into medium, more advanced, more backward three. 1, the case of medium-level factories ① Wisconsin state foundry mainly produces high quality requirements of large and medium-sized castings, such as pumps, valves, gear and so on. Most products are used in steam turbines, aircraft and submarines. Castings are mainly made of high-grade cast iron, nickel-based and copper-based alloys. The plant started in 1912, the plant is larger, the equipment is basically the level of the sixties. Physical and chemical testing equipment, X-ray, fluorescence analysis, spectral analysis, computer data processing, as well as mechanical experiments
