由冶金工业部鞍山热能研究院研制成功的新型直冷式电极瓦通过该院与辽阳铁合金厂合作,在生产碳素铬铁的两座6300kVA 封闭式矿热炉上安装使用,从1987年4月6日投入生产运行到1991年4月末止,历经4年多的生产实际考验,使用效果良好。这项成果于1992年1月15—16日通过了冶金部的技术鉴定。与会代表们经过认真讨论与评议一致认为这种铜瓦有如下优点:1.水冷面积大,不易结垢,冷却效果好,从而减少了电阻损失;
The new type of direct-cooling electrode tile successfully developed by Anshan Institute of Thermal Energy of the Ministry of Metallurgical Industry was installed and used on two 6300kVA enclosed submerged arc furnaces for producing carbon ferrochromium through cooperation with Liaoyang Ferroalloy Plant from April 1987 On the 6th put into operation until the end of April 1991, after more than 4 years of production of the actual test, the use of good results. This result passed the technical appraisal of the Ministry of Metallurgy on January 15-16, 1992. Participants after careful discussion and comments agreed that this kind of copper tile has the following advantages: 1. Water-cooled area, not easy scaling, cooling effect, thereby reducing the resistance loss;
