Steel is an alloy of iron that has enhanced chemical and physical properties. The most commonly found steels are alloyed with between 0.2 percent and 2.15 percent of carbon, but some steels can be found that are alloyed with other materials like tungsten, chromium, vanadium and manganese. Steel …
If the cold mill rolls or hot mill coils have too much crown, the mills will roll out the center, creating center buckle in the process (see Figure 8). If the cold mill rolls or hot mill coils have too little crown, the mills will roll out the edges and create edge wave (see Figure 9). This is fairly common in mill master coils.

Pickling is a metal surface treatment used to remove impurities, such as stains, inorganic contaminants, rust or scale from ferrous metals, copper, precious metals and aluminum alloys. A solution called pickle liquor, which usually contains acid, is used to remove the surface impurities.It is commonly used to descale or clean steel in various steelmaking processes.
12/5/2007· You're talking of "sheets" of steel. Sheets have been rolled, either hot or cold rolled; so the grains run in the same direction of rolling. MGD said the same thing with different words. When just small pieces are involved, you can't say which was the rolling direction, that's why MDG said it …
To clean work roll surfaces, put a Scotch-Brite® pad, carpet, or other cloth fastened to a T-shaped plywood board (seeFigure 1) into the slowly turning but empty flattener or leveler roll nip and hold it there.The T should be wider than the machine frame so the board will not pass through.

Steckel Mill: Sheet rolling mill that reduces steel gauge by repeated reversal of rolling action. Heated coil boxes at each end allow the steel to be reheated prior to each reversing pass through the Steckel mill's stands: Strand: A combination of individual steel wires that are specially twisted together.
Steel has the tendency to cling to its original shape and molecular composition. Why? Because it was given a unique configuration when it was rolled, cooled, and coiled at the steel mill. In its natural state, steel is not at all flat. In fact, a hot-rolled sheet coil generally reveals some or all symptoms of poor flatness (see Figure 1).
1/18/2016· Roll Forming Process is a type of rolling involving the continuous bending of a long strip of sheet metal (typically coiled steel) into the desired cross-section. Roll forming involves uncoiling a long strip of metal and sending it through several stacks of rollers set up in a long line.

Electrical steel (lamination steel, silicon electrical steel, silicon steel, relay steel, transformer steel) is an iron alloy tailored to produce specific magnetic properties: small hysteresis area resulting in low power loss per cycle, low core loss, and high permeability.. Electrical steel is usually manufactured in cold-rolled strips less than 2 mm thick.
10/10/2002· Sources of Shape Defects. The mills have come a long way in the last few years in controlling shape and thickness, but perfection is difficult. You need to understand this--not because you're going to be in the rolling mill business, but because you must be realistic when talking to the mills about your expectations for product quality.
