铅厂联合有限公司研制了一种从铅精炼锅自动除浮渣的改进方法并已取得专利. 该系统采用一种特殊设计的机器,它可以脱除所有形式的干渣和半干浮渣,脱除迅速有效,除渣后铅熔体表面实际上已无浮渣,由于烟罩结构几乎完全密闭,卫生环境得以改善. 第一台生产规模样机于1982年11月在铅厂联合有限公司的Elswick厂投产,生产证明这台机器在险恶环境中非常可靠,至今已脱除12,000吨以上的浮渣。根据这台样机在试用阶段的情况.在7台撇渣机里作了进一步的改进设计,现在可以处理Elswick厂产出的全部精炼浮渣. 铸锭和堆垛装置的专业厂商已取得制造这些撇渣机的许可证,目前在有色金属工业几家公司采用的这台装置已引起人们极大关注。
Lead Factory United has developed and patented an improved method of automatic scum removal from a lead refining pot using a specially designed machine that removes all forms of dry and semi-dry scum, Removal of swift and effective, after deslagging lead melt surface virtually no scum, as the hood structure is almost completely closed, the health environment can be improved.The first prototype of the production scale in November 1982 in the lead plant United Co., Ltd. The Elswick plant is in production and the production proves that the machine is very reliable in dangerous conditions and has so far removed over 12,000 tons of scum. Based on the prototype’s trial phase, further refinements were made in the seven skimmers and all of the refined scum from the Elswick plant can now be processed. Specialists in ingots and palletizers have made these Skimming machine license, the current non-ferrous metal industry in several companies using this device has caused great concern.
