Abstract
When a continuous cast slab is cut, such as by gas cutting, burrs tend to be caused at the cut edges. These burrs are removed by a plurality of edged cutting tools which are installed serially along the width of the slab to be treated. Each of the edged cutting tools may be selectively raised or tilted in the vertical direction or moved in the horizontal direction to substantially follow the warped or otherwise uneven surface on which the burrs are located. In this manner, substantially all of the burrs are exactly and completely removed.
