The strips are processed in single-strand longitudinal blasting principle, using 4 blast wheels. 

The blast wheels are inclined to the strip plane to avoid blast interferences. Quick, exact and automatic adjustment of all 4 blast wheels for a new strip programme permits full exploitation of the blast stream in the entire width range and results in high descaling performance and quality. Strips up to widths of 600 mm can be blast cleaned, feed rate is approx. 30 m / min.
