An apparatus for removing surface oxidized iron sheets of high temperature billets comprises a frame, a roller brush and a driving device. The apparatus is characterized in that the roller brush comprises an upper roller brush, a lower roller brush and a side surface roller brush; the driving device includes an upper and a lower roller brush running motor, an upper and lower roller brush adjusting motor, and a side surface roller brush adjusting motor; and the apparatus also comprises an upper and lower roller brush adjusting rod, a side surface roller brush adjusting rod, a guide post, an adjusting screw, a universal joint and a reduction box. The enforcement of the utility model requires no change of the present production line, and only needs the arrangement of the apparatus between the two rolling ways. The apparatus removes surface oxidized iron sheets of billets in omni-directional mode, brushing-off is carried out after rolling, the bristles of the roller brush are arranged in V shape, and thus crushed iron oxide sheets fall down along the V-shaped brushing way and two ends of the roller brush to prevent accumulation of iron oxide sheet power, and self-damage of equipment can be effectively avoided.
