the descaler and brushing unit combines a four-pulley descaler and four steel brush groups to remove the oxide. each steel brush group consists of a high speed motor and a transmission shaft. the pressure of the brushes against the wire surface is adjusted through the pneumatic cylinder, not only ensuring the thorough removal of the oxide coating, but also greatly reducing the acid consumption and prolonging the service life of the brushes and hence lowering the comprehensive cost. the whole unit is set within a closed box, which include the dust and exhaust pipe joints on the top and a dust removal device in the lower part.
the wire diameter is φ5.5—φ8.0 mm ,more than φ8.0 mm is available , the speed of treament is more than 2m/s.
