Steel - Primary steelmaking | Britannica

Steel - Steel - Primary steelmaking: In principle, steelmaking is a melting, purifying, and alloying process carried out at approximately 1,600° C (2,900° F) in molten conditions. Various chemical reactions are initiated, either in sequence or simultaneously, in order to arrive at specified chemical compositions and temperatures. Indeed, many of the reactions interfere with one another ...

Mill Scale – Beshay Steel

Mill scale is molded on the outer exteriors of billets when they are being manufactured in rolling mills. It is an assortment of iron oxides, regularly, ferric and is dark in color. It is commonly less than 0.1 mm and primarily follows the steel exterior and protects it from environmental erosion to avoid any damage.

v0.34:Ore - Dwarf Fortress Wiki

Ores are left behind after mining certain varieties of stone.Ore can be smelted to create bars of pure metal or combined to create alloys.Many ores are quite valuable as mined without being refined, and a mason or stone crafter can work them the same as any stone. However, ores fall into the economic stone category, and so must be designated for non-restricted use in the z-stone menu.

Magnetite - Wikipedia

Magnetite is a rock mineral and one of the main iron ores, with the chemical formula Fe 3 O 4.It is one of the oxides of iron, and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself. It is the most magnetic of all the naturally-occurring minerals on Earth. Naturally-magnetized pieces of magnetite, called lodestone, will attract small pieces ...

Magnet - Wikipedia

A magnet is a material or object that produces a magnetic field.This magnetic field is invisible but is responsible for the most notable property of a magnet: a force that pulls on other ferromagnetic materials, such as iron, and attracts or repels other magnets.. A permanent magnet is an object made from a material that is magnetized and creates its own persistent magnetic field.
