一九八四年七月二十六日至三十一日,机械工业部基础件局在山东益都召开了铸造技术攻关经验交流会。国内从事液压件铸造生产和发研工作的十五个生产厂、五个专业公司、七个大专院校和科研单位的46名代表参加了会议。会上交流的专业论文和经验材料共24篇,其中大会交流20篇,书面交流4篇。在交流期间,同时展示了有关的实物、样品和图片。液压处处长姚子玉同志到会并做了总结性科言。认为:就去年第四次专业会议布置的15个攻关课题的进展情况而言,取得较大进展的有5项、取得一定程度进展的有7项。另外几个项目虽然已经起步,但进展还不太明显。
From July 26th to 31st, 1984, the Basic Parts Bureau of the Ministry of Machinery Industry held an experience exchange meeting on casting technology in Yidu, Shandong. At the meeting, 46 representatives from 15 production plants, 5 professional companies, 7 colleges and universities and scientific research institutions engaged in the production and initiation of hydraulic parts castings participated in the conference. There were 24 professional papers and experiential materials exchanged at the conference, including 20 conference exchanges and 4 written exchanges. During the exchange, relevant physical objects, samples and pictures were also displayed. Director of Hydraulic Division Yao Ziyu attended the meeting and made summative words. It is believed that: As far as the progress of the 15 research projects laid out in the fourth professional conference last year, there have been 5 projects that have made significant progress and 7 projects that have achieved some degree of progress. Although several other projects have started, progress has not been obvious.
