steel rolling mill hot rolled pickling
Cold Strip Mill Cold rolled strip steel and sheet steel generally have a thickness of 0.1 - 3 mm and a width of 100 - 2000 mm; All of them take hot rolled strip steel or steel plate as raw materials and are rolled into products by cold rolling mill at normal temperature. SheetSteel sheet is processed to its final thickness by rolling at high temperatures on a hot-rolling mill. This process can be taken a step further by pickling and oiling, which is a method of removing the surface oxides and applying an oil to improve lubricity and provide a more rust-resistant product.
After hot-rolled sheet is pickled, leveled, and edge-trimmed, our cold-rolling mill is capable of reducing the steels thickness to as thin as 0.013 inches and as thick as .085 inches. Coated steel sheet. We galvanize hot-roll and cold-roll steel sheet, offering galvanneal, Aluminized Type 1 and Galvalume®, as well as acrylic overcoat options. Steel Pickling:A Profile - US EPAsteel mill products at 78.8 million tons.4 Although statistics on the percentage of total steel mill products processed by pickling operations are not available, we can infer from the above data that roughly 55 percent of all steel mill products in 1991 were pickled. This Steel strip processing [SubsTech]Oct 31, 2013 · Cold rolling in a tandem rolling mill. The rolling mill consists of 5-7 stands having four-high configuration (two large back-up rolls and two small work rolls). Annealing at a temperature 1100-1300ºF (600-700ºC) in a controlled reducing atmosphere (commonly a mixture of Hydrogen and Nitrogen ) preventing oxidation of the steel surface.
Steel Hot Rolling Mills Temperature Monitoring Temperature Control in Hot Rolling Mills. Hot Rolling Mills are used to reheat shapes of steel to soften them enough so that they can be rolled thinner and longer through a series of rolling stands. The finished product can be either a strip, plate, rod, bar, wire, or shape (rails and H-beams). The manufacturing route for tinplate productsduring rolling. After the continuous pickling process, the strip is rinsed, dried, edge trimmed, oiled and rewound into coils. 2 Cold rolling The tandem cold rolling mill takes the pickled hot rolled strip and rolls it to achieve its final thickness of between 0.12 and 0.49 mm The tandem mill has several stands equipped with a four high U001en Hot-Rolled Steel Sheets and CoilsPickling 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.
