PROBLEM TO BE SOLVED: To solve such a problem that the opening/closing of a door becomes difficult by sticking and solidifying skull and slag at a boundary between the back surface of a hang-down type inspection door 1 and the fixed wall 2 of a dust collector of exhaust gas in a converter. SOLUTION: A power cylinder 3 and a reaction device 4 are provided at the lower end part of the inspection door 1. The door 1 is moved in the opposite direction against the fixed wall 2 of the dust collector under pressing a pushing device 14 at the upper part and the stuck skull 21 is removed and fell down.
