摘要：A method and apparatus for the descaling of metal surfaces without the use of caustic substances is provided. The apparatus includes a first and second blast heads containing nozzles that spray high velocity jets of media at a scale covered continuous sheet of steel. The continuous sheet of steel is advanced into an abrading station containing a pair of brush assemblies that include stainless steel bristled brushes. The stainless steel brushes engage the surface of the sheet of steel and abrade away the cracked scale, leaving a surface clean of scale. The surface produced is pH neutral and therefore resists additional corrosion and does not require oil coatings, or other protective treatments. Eliminating these steps makes for a faster, more robust process and saves considerable cost.
