大吨位真空自耗电弧炉是生产大规格钛材等的关键设备,大直径铜坩埚是该类设备的必需部件。以前我国缺乏制造此部件的技术手段,以致严重影响了大吨位钛铸锭的生产。自从1970年以来,国内先后试用电解沉积、焊接等方法制造,均未获明显效果投入 Large-tonnage vacuum consumable arc furnace is the key equipment for producing large-size titanium, etc., and the large-diameter copper crucible is an essential part of this kind of equipment. In the past, China lacked the technical means to manufacture this component, which seriously affected the production of large-tonnage titanium ingots. Since 1970, China has tried electrolytic deposition, welding and other methods of manufacturing, have not been significantly effective investment
