特殊合金和不锈钢是在真空感应熔炼炉中制造的。在这些炉里产生的电极在真空中再熔，并在进一步精炼中直接压制。通过电流控制凝固过程使得无分离钢锭的制作成为可能，而这在铸件工艺中则是不可能的任务。
　　Special alloys and stainless steels are manufactured in vacuum induction melt furnaces. Electrodes produced in these furnaces are remelted in vacuum with electrodes pressed directly in further purification. Solidification is controlled by electronic circuits making possible segregation-free ingots - a task impossible to achieve with castings.

　　合金钢热是在脱气装置下进行真空处理，以将氢接触减少到百万分之二以下，并减少金属氧化物。钢锭的浇铸通常是在氩保护下进行的。所有工艺过程都是采用高级尖端的设备，并在实验室观察眼中进行的。
　　Alloy steel heats are vacuum-treated on degassing units to reduce hydrogen contact to less than two parts per million and reduce metallic oxides. Teeming (pouring) of ingots is done usually under argon protection. All processes proceed under the watchful eyes of the laboratories using sophisticated equipment.
