Blast Furnace - an overview ScienceDirect Topics

Blast furnace slag is a nonmetallic coproduct produced in the process in the production of iron from iron ore or iron scrap. 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

Explain blast furnace.

The blast furnace is a huge, steel stack lined with refractory brick, where iron ore, coke and limestone are dumped into the top, and preheated air is blown into the bottom. The raw materials require 6 to 8 hours to descend to the bottom of the furnace where they become the final product of liquid slag and liquid iron.

Describing the Use of Limestone in a Blast Furnace

A blast furnace can be used to extract iron from its ore. Components other than just the ore are added to the furnace to extract the iron. One of these key components is limestone, which is primarily composed of calcium carbonate, CaCO3. The heat from the blast furnace causes the calcium carbonate to decompose into calcium oxide and carbon dioxide.
