EPS vs. Acid Pickling - EPS - Eco Pickled Surface

As a process for descaling hot rolled strip, EPS directly competes with acid pickling. More mills, picklers and processors are choosing EPS because of its demonstrated advantages over acid pickling. The evidence of those advantages is provided throughout this web site, but the table below provides a helpful summary of the most important ones.. As a product, EPS pickled strip is used Effect of Coiling Temperature on the Formation and Steel strips covered by a tertiary thermal oxide scale from a hot rolling process were studied in this research work. In case that the clean strip is required, i.e. for the cold rolling process, this tertiary scale formed on the steel surface is typically removed by a pickling process. In this work, a finishing temperature the temperature at the exit of strip from a finishing mill was

Fixing Adhesion Issues on High-Carbon Steel Products

Jan 22, 2018 · A. Adhesion issues can be common on high-carbon, heat-treated steel, and one of the primary areas on which to focus when addressing this issue is the acid pickling stage of the process. High-carbon steel generally can be classified as an iron-carbon alloy, ranging from 0.55 to 1.40 percent carbon. High-carbon steel is harder and stronger than regular mild steel, and it is often heat-treated Glossary of Steel Industry Terms - American Iron and Steel Strip. Thin, flat steel that resembles hot-rolled sheet, but it is normally narrower (up to 12 inches wide) and produced to more closely controlled thicknesses. Strip also may be cut from steel sheet by a slitting machine (see Sheet Steel). Structurals. Steel product group that includes I-beams, H-beams, wide-flange beams, and sheet piling.

Hot Rolled Pickled & Oiled Steel Sheet & Coil - Steel

Steel Pickling is the process of descaling Hot Rolled Steel in a hydrochloric acid bath. This scale-free surface benefits welding, painting, bending, stamping, and laser burning both in production savings and the quality of the finished part. Get a Quote Ask an Expert Hot Rolled Steel AK SteelThe finishing mill produces excellent thickness and crown control on all AK Steel Hot Rolled Steels. Finally, pickling can be used to remove the oxide that forms during hot rolling. JOINING SYSTEMS Most Hot Rolled Steels can be readily fabricated using a variety of welding and joining processes.

Hot Rolled Steel Sheet, Pickled and Oiled Steel Products

Hot Rolled Pickled and Oiled hot rolled coil or sheet steel that has been descaled of oxide film by either a chemical method, mechanical method, or a combination of both and oiled to help retard corrosion during storage and after descaling. "HRPO" is available in various gauges, widths, and cut lengths or coil. Hot Rolled Pickled & Oiled ASTM A-1011 Hot Rolled Strip Scientific.NetAbstract:The hot rolled strips for internal plates of automobile was developed by taking the technologies of low-carbon softening steel, including strictly control the chemical composition content during the steel melting and optimization of the rolling processes in

Pickling Behaviour of 2205 Duplex Stainless Steel Hot

Abstract. Pickling behaviour of the oxide layer on hot-rolled 2205 duplex stainless steel (DSS) was studied in H 2 SO 4 solutions with electrolytic workstation. The pickling rate at 75°C increases slightly with the H 2 SO 4 concentration from 100 to 250 g L 1 but increases markedly as the concentration is higher than 250 g L 1.The solution temperature greatly accelerates the pickling rate. Pickling Samuel Steel Pickling GroupPickling. Pickling is a process to clean metal surfaces of stains, contaminants, rust, or scale through a chemical reaction that the surface metal undergoes when passed through a pickling line. Depending on the grade of the material being pickled, and the surface condition of the metal, the speed of the strip may be adjusted to allow for

Pickling of Steel Q&A's - Finishing

Aug 17, 2016 · The surface of the hot steel is going to react with the oxygen and water vapor in the air, forming something similar to a very heavy rust. This is called 'scale'. The scale needs to be removed, and 'pickling' is usually the name given to the chemical (acid) removal of scale. Ted Mooney, P.E. Rizhao Steel's pickling and galvanizing lineThe subsequent chemical pickling with hydrochloric acid and an additional spray pickling section at the entry and exit of the pickling tank deliver scale-free hot strip to the first skin pass mill (SPM1). Strip flatness is improved by skin passing, and strip roughness

A hot rolled or annealed stainless steel strip (10) covered with scale is immersed into hot inorganic acid contained within pickling tanks (12) and (14). Thereafter, the strip may have residual amounts of tightly adherent scale (11).
