Coolers with water circulating in them are installed between the shell of the blast furnace and the refractory lining in the upper part of the furnace to protect these components from heat radiation. In addition to having its own coolers, the part of the shell adjacent to the hearth and the bottom of the furnace is also cooled in some furnaces on the outside by water sprays.
Get a Quote Blast Furnace Blast furnaces are used to produce iron. Iron was the material that gave rise to the Industrial Revolution. Abraham Darby created the first blast furnaces fueled with coke instead of charcoal.
Charcoal is created from burning trees and requires a lot of labor and resources. Coke is created from coal which is less labor intensive and saves community timber resources. The coke mixed with iron ore and limestone created a much stronger iron than could be made with charcoal.
Modern blast furnaces are made from refractory brick surrounded by steel. The hollow stacks receive raw iron ore, coke, and limestone through the opening at the top. Hot air is blown into the bottom of the stack.
The materials melt and combine to form liquid iron and slag which drains at the bottom.
The combination of high heat with the chemical compounds found in each raw material cause chemical reactions to occur within the furnace. These chemical reactions purify the iron ore and create iron.
The chemical reactions and the temperatures they occur are listed below.Hatch completed a pilot installation in of a pair of finger coolers in a blast furnace cast iron stave and a comparison of predictive models to site monitored temperature data will be presented using a series of thermal finite element analyses.

Iron production is one of America’s backbone industries. Iron was the material that gave rise to the Industrial Revolution.
A blast furnace is used to extract iron by literally melting it out of iron ore. Hot enough to liquefy iron, a blast furnace combines iron ore with other materials such as charcoal, coal and limestone. Then waves of extremely hot air are blasted into the furnace. This heat causes calcium in the limestone to combine with silicates from the other materials, creating slag.
Introduction. Induction furnaces are comprised of three main components. These components are the power supply (Fig. 1), the furnace bowl (Fig. 2) and the cooling system. blast furnace which do not experience extreme heat loads.
Copper staves are proving to be an effective and reliable blast furnace cooling element that are subject to virtually no wear and are projected to have a longer campaign service life in the areas of highest thermal load in the blast furnace.
