Claims

[Scope of utility model registration request]

It has a side wall and a ceiling wall that respectively surround the sides and top of the main body of an arc furnace for steelmaking, and an opening/closing door for suspending scrap packets and allowing them to pass through from the side is provided on the side wall, and a scrap packet hanging device is attached to the arc furnace. In an exhaust system for an arc furnace enclosure for steelmaking, which has an opening in the ceiling wall that can be moved laterally to the center of the main body, the exhaust system is attached to the ceiling wall surrounding the opening in the ceiling wall, and is attached to the side of the packet hanging device on the upper side. It is equipped with a suction duct for dust collection that has an opening with the minimum width that allows movement and a ceiling door that opens and closes the opening, and is configured so that exhaust gas can be discharged to the outside of the enclosure through the suction duct. An exhaust system for an enclosure for a steelmaking arc furnace, characterized in that:
