coke acts as a reducing agent. It combines with oxygen to form CO which in turn reacts with iron ore to give metallic Iron. Carbon present in coke also produces heat in all oxidation reactions which melts down the metallic iron.
Lime stone (CaCO3) breaks down to CaO upon heating which reacts with SiO2, the main impurity, to flux it out of the furnace
What else can I help you with?
How does limestone coke and iron ore get into the blast furnace?
through the top of the blast furnace
What substance are mixed with iron ore in the blast furnace?
Coke (a form of carbon) and limestone are mixed with iron ore in the blast furnace. Coke provides the heat source for the chemical reaction, while limestone helps to remove impurities from the iron ore.
How much coal coke is needed to run a blast furnace for one day?
that would depend on the size of the blast furnace.
Which three substances are put into the blast furnace?
In a blast furnace, iron ore (Fe2O3), coke (carbon), and limestone (CaCO3) are commonly used. Iron ore is the source of iron, coke acts as a fuel and reduces the iron ore to iron, and limestone helps remove impurities by forming a slag.
What is the charge in the blast furnace?
The charge in the blast furnace typically consists of iron ore, coke (a form of coal), and limestone. The iron ore is the main source of iron, the coke provides the heat and reducing agent, while the limestone helps remove impurities in the form of slag.
Pig iron is produced by heating the coke iron and limestone in a what?
Pig iron is produced when heating * Iron ORE (not iron as the question says!) * Coke * limestone in a Blast Furnace.
What goes into a blast furnace?
A blast furnace typically contains iron ore, coke (fuel derived from coal), and limestone. These materials are layered in the furnace and hot air is blown in at the bottom to create a chemical reaction that produces molten iron.
What are the 3 raw materials used in the blast furnace?
The three raw materials used in a blast furnace are iron ore, coke, and limestone. Iron ore is the primary source of iron, coke is used as a fuel and reducing agent, and limestone helps to remove impurities from the iron ore.
What are the three substances fed into the blast furnace?
The three substances fed into the blast furnace are iron ore (in the form of sinter, pellets, or lumps), coke (a form of carbon derived from coal), and limestone (which helps remove impurities from the iron ore and acts as a flux).
What are the raw materials fed into the blast furnace?
The raw materials fed into the blast furnace typically include iron ore, coke (a form of carbon), and limestone. Iron ore is the primary source of iron, coke acts as a fuel and reducing agent, while limestone helps remove impurities during the smelting process.
What raw material are put into a 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.
What is coke for in a blast furnace?
the Coke supplies carbon monoxide to reduce the ore in a blast furnace and supplies heat to melt the iron.
