As the iron travels down the molding line, the temperature gradually decreases from about 1,200 to 900 degrees Fahrenheit. Temperature at this stage varies based on the size of the casting as well as the molding rate. At the end of the mold line, castings enter a shakeout process where the molds are shaken off and the sand is recycled for reuse.

Ironsand, also known as iron-sand or iron sand, is a type of sand with heavy concentrations of iron. It is typically dark grey or blackish in colour. It is composed mainly of magnetite, Fe3O4, and also contains small amounts of titanium, silica, manganese, calcium and vanadium.

Metal Melting and Pouring: Life of a Casting Reliance

The process of melting the iron around the coke and additives adds carbon and other elements and produces different grades of iron and steel. Cupola furnaces are no longer usually used in production, as electric arc and induction methods are more efficient at producing the needed heat.

An Introduction to Iron Smelting Part I: Theory Harald

The Basic MechanicsOreFuelThe FurnaceIronSteelAfter The Smelt Processing The BloomA Conclusion to Part IThe smelting, or reduction, of iron ore is a thermochemical reaction, wherein the iron oxides are reduced to metallic iron. Impurities in the ore are melted out of the ore in the form of slags most commonly iron silicates while the iron itself is never truly molten. Instead the product of the smelt is a spongy mass of iron and slag known as a ‘bloom’. This then needs to be consolidated by hammering while the bloom is at a (white) welding heat. In doing so, the slags trapped in the bloom a...

Iron sand Smelting, Melting, Foundry, and Casting I

Feb 28, 2013Iron Sand is the grains of magnetite that weathers out of igneous and metamorphic rock. It's fairly dense and so it collects in streambeds and along shores where the water concentrates it. You can collect it by dragging a magnet along such an area---shroud the magnet so when it sticks to it you can pull off the shroud and dump your collection.
