Blast furnace - Wikipedia

A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally pig iron, but also others such as lead or copper. Blast refers to the combustion air being "forced" or supplied above atmospheric pressure. In a blast furnace fuel (coke), ores, and flux (line) are continuously.

IRON ORE SINTERING PART 2. QUALITY INDICES AND .

Improvements in the blast furnace process are achieved by technological improvements and a stable supply of high quality iron ores and sinters [1]. However, high quality . Table 1 sets out data on coke consumption, productivity, and sinter composition and quality indices in European sinter plants [2]. The figures show a.

Iron ore - USGS Mineral Resources Program

Iron ore consumption data are available for the United States, but not for the rest of the world. Because almost all iron ore is consumed in blast furnaces, the product of the blast furnace, pig iron, is used as the indicator of iron ore consumption. Iron ore consumption, as well as production, is concentrated in a few countries.

Steel: What are the benefits of combined moisture (LOI) in Iron .

The effect is prominent in sinter. High LOI means high porosity of iron ore( As when exposed to high temperatures, moisture escapes leaving voids behind). Iron ores with high loss on ignition affects the sintering process in a negative way by reducing the productivity, increasing the specific fuel consumption and reducing the.
