美国加利福尼亚州Frankel钛公司研制成一种可将各种形式和尺寸(其它工艺无法回收)的钛废料制成高密度钛电极的等离子系统,该成果获得洛杉矶地区1984年度的金属工艺成果奖。该系统在好几个方面优于其它工艺。例如,可使用以前一直难于回收的中等尺寸的废料;又如,钛电极通常是由几段废料焊接而成,而采用该等离子系统制造钛电极,则不需要焊接,电极密度可达85％,废料压制或焊接而成的电极密度只有50～60％,密度大意味着导电率高,这将提高熔炼速度。
Frankel Titanium, California, USA, developed a plasma system for producing high-density titanium electrodes from titanium scrap of various forms and sizes (other processes can not be recycled), which won the 1984 Metalworking Achievement Award in the Los Angeles area. The system outperforms other processes in several ways. For example, medium-sized scrap that has been previously difficult to recycle may be used. For another example, the titanium electrode is usually formed by welding several pieces of scrap material. However, the plasma system does not require soldering to manufacture the titanium electrode. The electrode density is up to 85% Scrap or welded electrode density of only 50 to 60%, the density means that the high conductivity, which will increase the rate of melting.
