Hot-rolled mild steel seems to have a wider tolerance for the level of included carbon than does cold-rolled steel, and is, therefore, more difficult for a blacksmith to use. Hot rolling is used mainly to produce sheet metal or simple cross-sections, such as rail tracks.
Metal is drained from the tundish through another shroud into the top of an open-base copper mold. The depth of the mold can range from 0.5 to 2 metres (20 to 79 in), depending on the casting speed and section size. The mold is water-cooled to solidify the hot metal directly in contact with it; this is the primary cooling process. It also ...
A metal detector is an instrument that detects the nearby presence of metal. Metal detectors are useful for finding metal objects on the surface, underground, and under water. A metal detector consists of a control box, an adjustable shaft [dubious – discuss], and a variable-shaped pickup coil. When the coil nears metal, the control box ...
A billet is a length of metal that has a round or square cross-section, with an area less than 36 in 2 (230 cm 2). Billets are created directly via continuous casting or extrusion or indirectly via hot rolling an ingot or bloom. [1] [2] [4] Billets are further processed via profile rolling and drawing. Final products include bar stock and wire. [3]
The term long products may include hot rolled bar, cold rolled or drawn bar, rebar, railway rails, wire, rope (stranded wire), woven cloth of steel wire, shapes (sections) such as U, I, or H sections, and may also include ingots from continuous casting, including blooms and billets. Fabricated structural units, such bridge sections are also ...
Cold-formed steel (CFS) is the common term for steel products shaped by cold-working processes carried out near room temperature, such as rolling, pressing, stamping, bending, etc. Stock bars and sheets of cold-rolled steel (CRS) are commonly used in all areas of manufacturing.
