1. A system for installing and removing a porous plug for a port of a metallurgic ladle, the system comprising:
a handler configured for selectively securing and transporting the porous plug to and from the metallurgic ladle, the handler comprising:
a mast disposed at a first end of the handler, the mast configured for retaining the porous plug during transport;
an extendable boom rotatably coupled to the mast, wherein the mast is rotatably moveable relative to the extendable boom to control alignment of the mast in response to movement of the extendable boom; and
a base configured for being secured to a plant floor, wherein the extendable boom is moveable relative to the base to align the mast with the port;
wherein the boom is pivotable up and down relative to the base and pivotable left to right relative to the base;
wherein the mast and boom are moveable relative to each other, such that the mast is positionable in an axially aligned position with a port of the ladle when the extendable boom is moved relative to the base; and
wherein the mast is pivotable both up-and-down and left-to-right in response to corresponding pivoting movement of the boom to position the mast in axial alignment with the port of the ladle.
