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.

EPS provides important advantages in flexibility and simplicity of operation over Conventional Acid Pickling by avoid pickling, shot blasting, painting and other pretreatment processes to achieve green and clean production.The technology currently has corresponding application production lines in China, such as: Angang, Taigang, etc., and it complies with the IATF16949 standard.

EPS pickling is safe and recognized as environment-friendly. Instead of caustic acids, EPS uses carbon tempered steel grit, available world-wide, mixed with ordinary water. It continuously recycles and re-uses these ingredients.
