《JDJL—1高效、无公害精炼剂》(又名三气精炼剂)技术鉴定会于82年10月15～16日在上海交通大学举行,来自全国44个单位的67名代表出席了会议。代表们分别听取了研制报告和试用报告,参观了上海仪表铸锻厂、上海船厂铸锻分厂现场,并进行验证性测试。 目前国内工厂熔炼铝合金,普遍使用的精炼剂效果虽好,但产生大量有毒气体,污染环境,亟待解决。以上海交通大学铸工教研组为主,上海仪表铸锻厂、上海新南中学等单位参加共同研制成功的JDJL—1高效、无公害精炼剂,既保证精炼效果良好,又无公害。它和国外的三气精炼相比,可
“JDJL-1 efficient and pollution-free refining agent” (also known as the three gas refining agent) Technical Appraisal meeting was held in Shanghai Jiaotong University from October 15 to August 16, 82, and from the country’s 44 units of 67 representatives attended the meeting. The delegates listened to the research report and the trial report, respectively, visited the Shanghai Instrument Casting and Forging Factory, Shanghai Shipyard Casting and Forging Plant site, and conducted the confirmatory test. At present, smelting aluminum alloy factory in China, commonly used refining agent effect is good, but produce a lot of toxic gases, pollute the environment, urgent solution. Shanghai Jiao Tong University Casting Teaching and Research Group mainly Shanghai Instrument Casting and Forging Factory, Shanghai Xinnan Middle School and other units to jointly develop a successful JDJL-1 efficient, pollution-free refining agent, both to ensure good refining effect, but also pollution-free. It is compared with the three foreign refining, can
