ESR method - ESR method

… There are two common methods for producing ingots: one is to cast into a mold (ingot case) and cast the same number of ingots at the same time as the mold, and the other is to cast into a bottomless mold with only a periphery and cast continuously. In addition, there are various vacuum ingot casting methods that control the amount of nitrogen, hydrogen, oxygen, etc. by vacuum treatment, and the electroslag melting method (ESR method) that uses a cast ingot as an electrode to remelt the molten slag by the electrical resistance heat, dripping it into the slag and gradually solidifying it, which are used in special cases. Continuous casting has been used for non-ferrous metals for a long time, but in recent years it has also spread to steel, and in 1980 more than 60% of Japan's crude steel production was produced by continuous casting. …

Japanese:

… インゴットの製造法は,鋳型(インゴット・ケース)に鋳込んで鋳型の数だけ同時に造塊する方法と,周囲だけで底のない鋳型に鋳込んで連続的に鋳造する連続鋳造の2方法が多く行われている。そのほか,真空処理により窒素,水素,酸素などの量をコントロールする各種の真空造塊法,一度鋳造したインゴットを電極として,溶融スラグの電気抵抗熱によって再溶解し,スラグ中を滴下させて順次凝固させるエレクトロスラグ溶解法(ESR法)などが特別な場合に行われる。連続鋳造は,非鉄金属では早くから行われてきたが,近年では鉄鋼にも普及し,1980年には日本の粗鋼生産量の60%以上が連続鋳造で生産されるようになった。…
