Iron and steel slags are coproducts of iron and steel manufacturing. In the production of iron, the blast furnace is charged with iron ore, fluxing agents, usually limestone and dolomite, and coke as fuel and the reducing agent. The iron ore is a mixture of iron oxides, silica, and alumina. From this and the added fluxing agents molten slag and ...

5 days agoEAF slag is a rock-like material generated during the steel-making process. Approximately 130 facilities across the United States generate EAF slag. EAF slag is used as an alternative to rock fragments, both in encapsulated uses (e.g., contained in concrete) and unencapsulated uses (e.g., loose ground cover material).

It is quite efficient to weld small metallic pieces using traditional welding methods But when it comes to welding materials that are thicker than 30mm, electro slag welding can be a suitable replacement. This process of welding can be used to weld materials ranging from 30mm to 300mm. Electroslag welding is a single pass welding process, hence it is very convenient to weld thick materials.

Slag is composed primarily of silica and lime, with concentrations of other minor constituents, including alumina, magnesia, and other compounds. During the fluxing process, slag removes the non-ferrous constituents from the molten iron, which purifies the product. Magnesium (Mg) is typically found in concentrations ranging from 1% to 10%, aluminum (Al) from 0.5% to 25%, and silicon (Si) from ...

Slag is a by-product of smelting (pyrometallurgical) ores and used metals. Broadly, it can be classified as ferrous (by-products of processing iron and steel), ferroalloy (by-product of ferroalloy production) or non-ferrous/base metals (by-products of recovering non-ferrous materials like copper, nickel, zinc and phosphorus). Within these general categories, slags can be further categorized by ...
