Iron ore fines are mixed at the ironworks with line, olivine, dolomite etc. and pre-fired at low temperature to form sinter, i.e. agglomerates which can then be fed to the blast furnace. Finely divided lime/dolime is often added to the.blast furnace line,What is the purpose of line in a blast furnace? - Quoraline is used to remove impurities in the furnace and the main impurity of the blast furnace is silica (sand and rock) which is silicon dioxide. silicon dioxide is a solid at furnace temperatures so it reacts with calcium oxide from the decomp.

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.

The Blast Furnace Process. 1. The Iron Ore, Coke and Line, (the Charge), is conveyed to the top of the Furnace. 2. The Charge is stored in Bells until the timing is right for the charge to be dropped into the Furnace. 3. Hot air is then blown through pipes called Tuyeres, to fire the mixture. 4. The Coke burns to increase.

Blast Furnace - ScienceAid

Blasts furnaces are used for smelting during the production of metals such as iron, lead, zinc, and copper. A blast furnace works by blasting hot air up through the furnace while fuels, line, and ore move continuously through the top of the furnace. The method used in blast furnaces have been used since the 1500's.

Steel making, blast furnace

To make the pig iron you need: iron ore, coke, line and, as we already said, a blast furnace. The iron ore is mined. The iron ore has chemical formula Fe2O3 – the iron-oxide. Almost all the iron in nature comes in this form. There is no metallic iron around (except, interestingly, if you find some iron-nickel meteorite).
