Abstract:
     The invention relates to a method for removing scale of cold rolling strip steel without acid. Wherein, the strip steel on the release machine, via the drawing roller, is fed to the cutter to be cut head or cut end; it uses welder to weld the head and end; feeding it to the wide adjustable free sheath to be stored; feeding it to multi-roller tooth scale remover to break the ferric oxide on the surface of strip steel; the steel brusher removes the left scale skin; in the scale removing box, the high-pressure water flows with the wet sand with 5% water content to brush the strip steel; washing it with water after removing scale; the strip steel via two steering rollers torsions the strip steel for 180 degrees; via another scale removing box, it removes the ferric oxide skin left on the back of strip steel; feeding it to another wide adjustable free sheath to be stored; feeding it to passive groove; to passivate the strip steel; the strip steel via another cutter is cut; the cut strip steel is fed to the coiling machine to be coiled. The invention has lower cost and lower metal consumption of strip steel, without fuel consumption.
