Carbon For Titanium Slag Furnace

Electric Arc Furnace Operation

Electric Arc Furnace Operation

Materials melted in the carbon-lined furnace generally provided higher slag quality than those processed in the magnesite-lined furnace, particularly with respect to the lime and magnesia content. Accordingly, most tests were conducted in a carbon-lined furnace shell to provide optimum slag quality.

Titania slag smelting and calcination of crude zinc

Titania slag smelting and calcination of crude zinc

-enriched slag with a typical titanium content of 85% if expressed as TiO 2. (In reality up to half the titanium in the slag is in trivalent form; the rest is mainly tetravalent). The typical process temperature – controlled by the presence of a slag freeze lining and hence dependent on the slag melting point3 – is in the range of 1600-1700°C.

The hot air burns the coke and makes carbon dioxide. Carbon dioxide reacts with more coke to form carbon monoxide. Carbon monoxide reacts with iron oxide and forms molten iron and carbon dioxide. The molten iron sinks to the bottom. Limestone reacts with impurities and forms slag which floats on top of the molten iron.
