Blast Furnace Operation an overview ScienceDirect
A blast furnace is a reactor which produces an impure form of molten iron, termed ‘hot metal’, from ferrous bearing ores. The principal raw materials used in the blast furnace operation consist of 1. Metallurgical coke, ferrous bearing feeds and fluxes charged via the furnace top.

HOW A BLAST FURNACE WORKS Foundry Gate
2018-7-10 The purpose of a blast furnace is to chemically reduce and physically convert iron oxides into liquid iron called "hot metal". 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. These liquid products are drained from the furnace at regular intervals. The hot air that was blown into the bottom of the furnace ascends to the top in 6 to 8 seconds after going through numerous chemical reactions. Once a blast furnace
