为了改进熔炼工艺,提高铝及铝合金产品质量,深圳金属特种材料有限公司、中国科学院金属研究所、东北轻合金加工厂、中国有色金属学会合金加工学术委员会轻合金专业学组共同发起,于2月13～14日在哈尔滨东北轻合金加工厂召开“铝合金添加剂、精炼剂推广应用交流会”。30个单位的49位代表参加了会议。代表们发言指出:熔炼是铝合金产品生产的头道工序,它对产品的质量起着重要影响。从70年代末以来,国外铝加工厂广泛应用铝合金添加剂,取代以中间合金形式向铝中添加合金元素。采用高纯金属粉末和有利于精练作用的盐类,按严格配比均匀混合压制成型,向铝
In order to improve the smelting process and improve the quality of aluminum and aluminum alloy products, Shenzhen Metal Special Materials Co., Ltd., Institute of Metal Research, Chinese Academy of Sciences, Northeast Light Alloy Processing Factory, China Nonferrous Metals Society of alloy processing Academic Committee of Light Alloy professional group co-sponsored by the 2 January 13 to 14 held in Northeast Light Alloy Factory in Harbin, “aluminum additives, refining agent to promote the application of exchange.” 49 delegates from 30 units attended the meeting. The delegates pointed out: Smelting is the first procedure in the production of aluminum alloy products, and it has an important influence on the quality of the products. Since the late 1970s, aluminum processing plants in foreign countries have extensively used aluminum alloy additives instead of adding alloying elements to the aluminum in the form of an intermediate alloy. The use of high-purity metal powder and salts conducive to scouring effect, according to strict proportioning evenly mixed molding, to aluminum
