今年4月21日至25日,美国铸造协会84届年会在美国圣路易市召开,同时举办了显示美国当前铸造工艺技术水平的展览会。中国代表团应邀参加了大会,并在会后参观了一些铸工工厂和大学铸工实验室。年会表明,美国铸造工业当前主要发展目标是:提高质量、提高生产效率、节约能源和控制环境污染。年会提出的口号是:为在1985年生产2500万吨铸件而努力;并提出质量是整个事业的基础。年会发表的139篇论文和专题报告中:占首位的是球墨铸铁方面的有关问题,重点是提高质量,扩大应用范围;其次是造型方法和材料,重点是树脂砂和水玻璃砂的研究和应用;第三是铸钢、铸铁和铸铝,重点是如何控制和提高质量;第四是熔化设备和方法;第五是环境保护和污染的控制及防治。前四组论文的主要内容,集中在如何控制、改进熔炼造型用的材料和工艺上,并提出要相应发展检测技术和装备,以达到提高铸件质量的目的。展览会中展出的各种型砂处
From April 21 to April 25 this year, the 84th annual meeting of the American Foundry Association was held in the city of St. Louis in the United States. At the same time, an exhibition was held to show the current state of the art of foundry technology in the United States. The Chinese delegation was invited to attend the conference, and after the conference, visited some foundry factories and university castor laboratories. Annual meeting shows that the United States foundry industry’s main current development goals are: to improve quality, improve production efficiency, save energy and control environmental pollution. The slogan put forward at the annual meeting was to work hard to produce 25 million tons of castings in 1985 and to say that quality is the foundation of the entire undertaking. Of the 139 papers and special reports published at the annual conference, the top priority is ductile iron related issues, with emphasis on improving quality and expanding the range of applications; secondly, modeling methods and materials, with a focus on resin sand and sodium silicate sand research and The third is cast steel, cast iron and cast aluminum, the key is how to control and improve the quality; the fourth is the melting equipment and methods; the fifth is the control and prevention of environmental protection and pollution. The main contents of the first four groups of papers focused on how to control and improve the material and process for smelting modeling, and proposed to develop testing techniques and equipment accordingly in order to achieve the purpose of improving the quality of castings. Various types of sand exhibited at the fair
