Oct 22, 2018 · The Cold Rolled Carbon Steel Sheet (CR) is produced by going through annealing and skin pass rolling after removing the scale from the surface (Pickling process) and after rolling to the degree of up to 0.15 ~ 3.2 mm in thickness with the hot rolled coil as its material. Compared with the hot rolled steel sheet, the cold rolled steel sheet is HBIS Product-HBIS Group-Being The Most Competitive Steel automobile structure steel. Application. Pickling products are mainly used for auto structure parts, such as house appliance compressor shell, enamel inner tank, sub-automobile frame, rear suspension system, torsional beam, trailer arm and seat cushion frame, and so on. Product size. 1.6-6.0mm×850-1650mm.
The pickling process removes scale from the hot rolled sheet surface by utilizing water and other inorganic solutions at the mill. After the scale is removed, an oil film is applied to guard against rust. The term steel refers to iron whereby 0.02 to 1.7% carbon has been added. There are many different types of steel and various alloys and Hot Rolled Pickling And Oiling Steel Plate OverviewPickling and oiling improves hot-rolled steel plate in durability and workablility at a low cost. It provides a cleaner surface hot rolled product suitable for painting with a limited barrier to rust formation. It is an all purpose steel product used for roll-formed shapes, pipe, tubing, industrial storage racks, automotive and other stampings, air compressor housings, filter housings

Pickling steels to remove rust and scalePickling is a finishing process in which heavy oxide crust or scale is removed chemically.. That is done by immersion in a bath, called pickle liquor, of suitable mixtures of acids.. Scale develops on the surface of iron or strip steel, steel wire, and some other forms of steel, during hot forming or heat treating in air.. The most used solution to treat Carbon steel products, with an alloy
Direct-reduced iron (DRI), also called sponge iron, is produced from the direct reduction of iron ore (in the form of lumps, pellets, or fines) to iron by a reducing gas or elementary carbon Servosteel Coil PicklingCoil Pickling is a process in which any surface scale or rust on the steel is removed to leave a clean substrate. It is only used for hot strip mill products. There are a number of steel pickling processes. Servosteel operates a modern push/pull shallow bath hydrochloric acid line. Steel coils are unwound in a very similar way to decoiling and
Cold-rolled sheet in coil form is produced by removing rust from hot-rolled sheet by "pickling" it in a weak acid solution, then washing, brushing, drying, oiling and unrolling the sheet and finally performing cold-rolling by passing the sheet through a reducing mill under pressure and winding it into a roll. Cold-rolled steel is a more highly finished product and has a smoother surface, Steel coil suppliers offer hot-rolled and cold-rolled Hot-Rolled Coil. Hot rolling is a process at the steel mill which involves rolling steel above its recrystallization temperature, typically over 1700° Fahrenheit. Steel that is heated above the recrystallization temperature can be shaped and formed more easily, which allows the steel to be made in much larger sizes.
The hot-rolled coil passes through the pickling line, where surface scales (iron oxide layer) are removed from the surface of the coil to give an (attractive) surface finish to the steel. In the pickling line, surface scales are removed with hydrochloric acid, and the coil is completely washed and dried before antirust oils are applied. U003en Cold-Rolled Steel Sheets and Coilsoffering light, strong, and pristine Cold-Rolled Steel Sheets and Coils that meet those demands.

Mar 21, 2016 · Thus, hot rolled pickled and oiled (from here on referred to as HRPO) flat rolled steel coils were born. HRPO steel is still considered hot rolled steel even though it does not have any scale. The final product of HRPO steel is created when steel mills use acid baths to remove the scale that usually forms on the surface of carbon steel coil, as [Product Manual] STEEL - CSVCEN10149-2 S315MC~S500MC P/O steel coils with high yield strength from the range 315 ~ 500 Hot Roll coil Pickling and oiling P/O coil 4.
