SPHE Carbon Pickled Steel Coils For Truck Beams

ACID WASHING; PICKLING;ACID PICKLING

The method of removing scale and rust on the surface of steel with an acid solution is called pickling. is a method of cleaning metal surfaces. Usually done with a pre-passivating treatment.
Generally, the workpiece is immersed in an aqueous solution such as sulfuric acid to remove films such as oxides on the metal surface. It is the pre-treatment or intermediate treatment of electroplating, enamel, rolling and other processes.

EPS INTRODUCTION

EPS (Eco Pickled Surface) is a new and environmentally advantageous technology began in 2006 to remove the oxide layer formed during hot rolling of flat rolled steel. The basic principle is that EPS accomplishes mechanical removal of scale using a unique “slurry blast” technology, in which a mixture of carrier liquid (water) and abrasive material impinges against the moving strip of steel. The force, angle and uniformity of slurry impact against the steel strip are precisely controlled to achieve complete scale removal, with no meaningful erosion of the steel substrate. Under the action of the impact force, the iron oxide scale on the surface of the steel plate is removed, and the steel plate becomes a smooth and clean surface.
