Claims (1)

【実用新案登録請求の範囲】[Scope of utility model registration request] アーク炉を囲繞する包囲体において、吸煙ダクトにより
包囲体内の排煙を吸引排除して包囲体内を外部の新鮮な
空気と置換するために包囲体の一部に空気流入口を鰻け
るとともにその開口面積を可変ならしめる開度調整用シ
ャッタ装置を設置し、このシャッタ装置により空気流入
口の開度を調節することにより外気吸入時に包囲体内の
負圧状態を保ち、包囲体の開口部からの洩煙を防止する
ようにしたことを特徴とするアーク炉包囲体。In the enclosure that surrounds the arc furnace, an air inlet is provided in a part of the enclosure and an opening is made in order to suck out the exhaust smoke inside the enclosure using a smoke suction duct and replace the inside of the enclosure with fresh air from outside. A shutter device with a variable area for adjusting the opening is installed, and this shutter device adjusts the opening of the air inlet to maintain a negative pressure state inside the enclosure when outside air is taken in, thereby preventing leakage from the opening of the enclosure. An arc furnace enclosure characterized by preventing smoke.
