The Manufacture of Steel

Zealand a rotary kiln is employed for direct reduction, followed by indirect reduction in an electric melter. This technology is used because the titanium dioxide present in the ore produces a slag which blocks conventional blast furnaces as it has a high melting point. The iron produced in this way always contains high levels of impurities making it very brittle. Steel making is mainly ......

Degradation mechanisms in refractory lining ...

Iron is one of the most important resources in the lithosphere; 90% of all metal ores extracted are based on iron. Many steps are included in the extraction of iron from ore, with extraction processes varying among different producers. Iron ore pellets are a prepared burden material for ironmaking in the blast furnace or by direct reduction. Such pellets can be sintered in a gratekiln furnace ......

OPERATIONAL ASPECTS OF SPONGE IRON PRODUCTION IN A ROTARY KILN

Sponge iron process uses a rotary kiln for the reduction of high grade lump ores or pellets (Fig. 1). The feed is introduced together with reducing and desulphurizing agents (lime stone or raw dolomite) into an inclined rotary kiln, heated counter current to the flow of hot gas and reduced to form sponge iron. Depending on its content of volatile matter, the coal is partly blown into the ......
