1978年在匈牙利布达佩斯举行的四十五届国际铸工会议上一共宣读了四十篇论文。绝大部分是铸造合金和工艺方面的论文。仅有三篇是属于铸造机械化和自动化方面的。以下是这三篇论文的较详细的摘要: 一、砂处理设备自动给水定量器的工艺技术问题,(作者:匈牙利Robert Breitner东德:Werner Tilch及Eckart Flemming) 文章一开始论述了控制型砂含水量的重要性,指出:型砂含水量的允许波动范围一般为±2％。然而对于目前的型砂水份定量装置,只有在旧砂成份比较均匀,温度比较低,混砂的时间长等条件下才能把含水量的变化控制在这一范围内。可是近代的铸造车
A total of forty papers were read in 1978 at the 45th International Foundry Conference in Budapest, Hungary. The vast majority are foundry alloys and process papers. Only three belong to casting mechanization and automation. The following is a more detailed summary of the three papers: one, technical problems quantitative automatic water filter sand processing equipment, (Author: Robert Breitner Hungary, East Germany: Werner Tilch and Eckart Flemming) beginning of the article discusses the moisture content of the sand control The importance of sand, pointed out: sand moisture content of the allowable fluctuation range is generally ± 2%. However, for the current sand moisture quantitative device, only in the old sand composition is relatively uniform, the temperature is relatively low, sand mixing for a long time under the conditions of the water content can be controlled within this range. But the modern casting car
