Description

本発明は金属を溶断加工する溶断装置に関する。   The present invention relates to a melting apparatus for melting metal.

従来、金属の溶断加工はガス溶断、プラズマ溶断、レーザー溶断等の溶断装置の溶断トーチで行なっている。   Heretofore, metal melting and cutting processes have been performed with a melting and cutting torch of a melting and cutting apparatus such as gas melting, plasma melting, and laser melting.

このため、溶断される金属の溶断部分は高温に加熱されるため、金属表面に酸化物スケールや酸化被膜が生成される。   For this reason, since the fused part of the metal to be fused is heated to a high temperature, an oxide scale or an oxide film is formed on the metal surface.

したがって、溶断後に溶接や塗料、メッキ等の処理を行なう場合、酸化物スケールや酸化被膜を除去しなければ溶接強度の低下や、塗料・メッキの品質の劣化となるが、その除去作業が大変で、コスト高になるという欠点があった。   Therefore, when processing such as welding, paint or plating after melting, if the oxide scale or oxide film is not removed, the welding strength will be reduced and the quality of the paint and plating will be degraded. There is a drawback that the cost is high.
