Claims

[Scope of utility model registration request]

A cell mount supported on a trolley so that it can move vertically and horizontally via a boom, an idle cell that is attached to the cell mount so that it can move forward and backward with a slide cylinder, and an idle cell that is attached to the guide cell so that it can move forward and backward. and a drilling plate having a drill rod for hole dismantling the tuyere sleeve, the device being removable from the front end of the guide cell at the base of the gas supply pipe of the tuyere sleeve to be dismantled. a joint member to which a gas supply pipe withdrawal attachment and a sleeve insertion attachment for inserting a new tuyere sleeve are removably attached; and a joint member that contacts the bottom wall of the furnace body and applies a withdrawal force to the gas supply pipe on the guide cell. A jack cylinder for operating the tuyere sleeve cover and a hanging arm for hanging the tuyere sleeve cover are respectively provided, and when the gas supply pipe is pulled out, the guide cell slides as the jack cylinder extends. A tuyere sleeve exchange device for a converter, characterized by incorporating a hydraulic control circuit that allows linear movement of the cylinder.
