PURPOSE:To descale uniformly without bending the material by a method wherein the descaling is effected from the oblique upward direction and the oblique downward direction of the material by two sets of descaling machines, whose one set is consisting of two machines, with predetermined angles. CONSTITUTION:The angle-like material such as an angle, a V-post or the like, is taken out by take-out rollers 9. Four sets of descaling machines 2a, 3a, 2b, 3b are arranged on horizontal lines, passing through respective corners of a rectangle standing uprightly about the material, so as to surround the material to be descaled. Upper and lower guide rails 4a, 4b, 5a, 5b, receiving and supporting the material against the projecting directions of the descaling machines 2a, 3a, 2b, 3b, are provided and, further, a guide ring 16, guiding and holding the material into a predetermined direction as well as feeding rollers 7 are provided in this device. |
