A system and method for installing and removing a porous plug relative to a port of metallurgic ladle includes an extendable boom rotatable about vertical axis and pivotable up and down at a first end of the boom. A mast is coupled to a second end of the boom and rotatable about multiple axes relative to the boom to position or maintain the mast in a given orientation, such as in alignment with the port of the ladle in response to rotatable or pivotable movement of the boom. The mast includes a slider mast that is translatable along the length of the mast to insert the plug or retract the plug. The mast may also include jaw grippers to secure the plug and may be configured to rotate the plug relative to the mast. The system may automatically control the position and orientation of the boom, mast, and slider mast.
