A method [and apparatus] for refurbishing eroded portions in coke oven doorjambs including refurbishing apparatus having a framework attached to the coke oven structure adjacent the doorjamb. The framework supports a carriage that is simultaneously moveable in an "X" axis direction and a "Y" axis direction within the boundary so that a machine[-cutting] tool, attached to the carriage, can be moved from one position directly to another position within the framework boundary. [The machine-cutting tool is positioned to make cutting] The machine tool is moved directly to selected positions within the boundary to make machining passes along new metal that is fused into the eroded portions of the coke oven doorjamb. |
