You don't. Carbon burns!
The fuel is carbon (as coke).
The refractory lining (fire-bricks) is made from minerals with very high melting-points.
A blast furnace is a type of furnace used for smelting to produce industrial metals like iron. It uses a continuous supply of air blown into the bottom of the furnace to create high temperatures for the chemical reactions to take place. A crucible furnace is a small, cylindrical furnace used for melting substances like metals for casting. It is lined with refractory material and can reach high temperatures quickly due to its compact size. This type of furnace is commonly used in laboratories and small-scale metalworking operations.
NO!!! Its primary purpose is to REDUCE iron ore to iron. Iron ore is the commercial name for iron(III)oxide ( Ferric Oxide). (Fe2O3) In the Blast Furnace , carbon forms carbon monoxide. , from the coke(carbon) and oxygen ( hot air blast). 2C + O2 = 2CO CO(carbon monoxide) is a very good reducing agent. Hence Fe2O3 + 3CO = 2Fe + 3CO2 The CO2 is not released into the atmosphere, but undergoes reduction to form more CO. NB THere are many more secondary reactions going on in the Blast Furnace.
Coal, distilled in a retort to expel the volatile content and leave the carbon as a spongy-looking solid called "coke".(Strange - there are several versions of this question, suggesting to me poor teaching or text-books that focus only on the chemistry and not the overall process, purpose?and materials.)?
Coal, distilled to drive off itscontents and leave the carbon, plus a little bit of non-volatile impurities, principally silica; in a form called Coke. (No relation to the colloquialcontraction of Coca-Cola! :-) )
The iron produced by a blast furnace is typically referred to as pig iron. It is a crude form of iron with high carbon content, which needs to be further processed to remove impurities and adjust its carbon content before it can be used in various applications.
A blast furnace is used to extract iron from its ore.

Mudgun is hydraulically operated machine that is used to close the tap hole of the blast furnace after draining out the metal / slag from the furnace from time to time. It is heavy equipment and the most critical of all the equipments used in blast furnace. The failure of the machine will lead to shut down of the furnace to close the tap hole.

The main products of a blast furnace are pig iron (used to make steel) and slag (a byproduct that is used in construction materials).
there are various kinds of refractory bricks for glass furnace using, and different bricks are using in different parts of glass furnace, the most widely used blocks is fused cast azs block. Zhengzhou Sunrise Refractory Co., Ltd. can provide excellent quality refractory, more details you can find in fusedcastazs.com
Refractory consumption per ton in an induction furnace refers to the amount of refractory material used during the melting process, typically measured in kilograms per ton of metal produced. This consumption can vary based on factors such as the type of refractory used, the operational practices, and the specific characteristics of the charge materials. Generally, the refractory consumption ranges from 5 to 20 kg per ton of metal, depending on the furnace design and operational conditions. Minimizing refractory consumption is essential for cost efficiency and operational effectiveness.
Because it is more reactive then carbon to be extracted in a blast furnace. Remember carbon is the reducing agent and for it to work the metal being extracted has to be lower in the reactivity series, e.g. iron
