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 ...

The composition of slag varies with the type of melting process used and the type of iron or steel being melted. The cleanliness of the metallic charge, often consisting of sand-encrusted gates and risers from the casting process or rust- and dirt-encrusted scrap, significantly affects the type of slag formed during the melting operation.

This type of slag has good physical properties, high inclusion absorptivity, and high sulfide capacity. Choi et al. [3] described two possible methods to recycle ladle slag: (a) by pouring molten ladle slag to another ladle, at time (taking advantage of the heat) and (b) by making a ladle slag ingot.

siliceous flux, and scrap copper are charged and gaseous products are vented. Air, or oxygen-rich air, is blown through the molten matte. Iron sulfide is oxidized to form iron oxide (FeO) and SO2. Blowing and slag skimming continue until an adequate amount of relatively pure Cu2S, called "white metal", accumulates in the bottom of the converter.

By-products, scrap and the circular economy. Steel is the only major material group today that can meet tomorrow's challenge of a fully circular economy due to its high recyclability, whereby 85-90% of steel products are recovered at their end of life and recycled to produce new steel. Making one tonne of crude primary steel with the typical ...

Blast furnace slag is a nonmetallic coproduct produced in the process. It consists primarily of silicates, aluminosilicates, and calcium-alumina-silicates. The molten slag, which absorbs much of the sulfur from the charge, comprises about 20 percent by mass of iron production.

During the steelmaking process, fluxes that consist of lime (CaO) or dolomitic lime, with iron and scraps, are charged to the furnace.There is a certain amount of free lime (f-CaO) in steel slag. Free lime, with a specific gravity of 3.34, can react with water to produce Ca(OH) 2, with a specific gravity of 2.23, which results in volume increase (Fig. 9.1).
