  • Patent number: 10260116
    Abstract: An apparatus for shaving a tap hole surface of a blast furnace or the like wherein efficiency can be improved, and a worker can be freed from physically burdensome work in the vicinity of the lower furnace wall of a blast furnace under high temperature. The apparatus includes a surface shaving unit having smoothing bits, and a rotating mechanism unit that, when the surface shaving unit is pressed against the tap hole surface, rotates the surface shaving unit, by utilizing the pressing force, by a predetermined angle in a predetermined direction substantially parallel to the surface, and holds the surface shaving unit at the rotated position. The rotating mechanism unit eliminates the need for work such that every time a conventional surface shaving unit is separated from the tap hole surface after being pressed against the surface, a worker manually rotates the surface shaving unit by a predetermined angle.
