Hot rolling is a metalworking process that occurs above the recrystallization temperature of the material. After the grains deform during processing, they recrystallize, which maintains an equiaxed microstructure and prevents the metal from work hardening. The starting material is usually large pieces of metal, like semi-finished casting products, such as slabs, blooms, and billets. If these products came from a continuous castingoperation the products are usually fed directly into the rolling mills at the proper temp
This is a list of primary aluminium smelters in the world. Primary production is the process by which alumina is smelted to pure aluminum metal. Secondary production is the process of recycling aluminum scrap into aluminum that can be used again. Capacity here refers to metric tonnes of output aluminum.
Aluminium foil is produced by rolling sheet ingots cast from molten billet aluminium, then re-rolling on sheet and foil rolling mills to the desired thickness, or by continuously casting and cold rolling.To maintain a constant thickness in aluminium foil production, beta radiation is passed through the foil to a sensor on the other side. If the intensity becomes too high, then the rollers

Jan 29, 2013· Milling can be done with a wide range of machine tools.The original class of machine tools for milling was the milling machine (often called a mill). After the advent of computer numerical control (CNC) in the 1960s, milling machines evolved into machining centers: milling machines augmented by automatic tool changers, tool magazines or carousels, CNC capability, coolant systems, and enclosures.

Most of aluminium sheet sold today comes from the rolling mills. Alcoa’s Micromill process, on the other hand, requires roughly 20 minutes to go from molten metal to sheet. The molten metal is poured onto a high speed caster that feeds into the series of rolling mills, going from molten to finished product in a continuous fashion.

Rolling Mills . In metal forming industry, rolls themselves do not function in isolation. In a metal rolling process, rolls, stands, bearings, housing, motors, and other mechanical equipment are all a necessary part of the manufacturing operation. The place where all the equipment for metal rolling manufacture is set up is called a rolling mill.

A rolling mill is a complex machine having two or more working rollers, supporting rollers, roll stands, drive motor, reducing gear, flywheel, coupling gear etc. Rollers may be plain or grooved depends upon the shape of rolled product. The metal changes its shape gradually during the period in which it is in contact with the two rollers.
History. Since the invention of the Bessemer process, steel mills have replaced ironworks, based on puddling or fining methods. New ways to produce steel appeared later: from scrap melted in an electric arc furnace and, more recently, from direct reduced iron processes..
