What are the 3 raw materials added to top of blast furnace?

The production of iron requires three important raw materials:

iron ore, coal converted to “coke”, and limestone

. The coal is converted to a product called coke in coking ovens. The three raw materials are added to the top of the blast furnace.

What material is added to the blast furnace to help remove impurities?

Forth – the carbon monoxide removes the oxygen from the iron oxide to produce iron metal and carbon dioxide.

What 3 ingredients are required to make steel in a blast furnace ‘?

Iron ore, coking coal, and limestone

are added into the top of the blast furnace while heated air is blown into the bottom of the furnace to drive the combustion process. The combustion of iron ore with other materials in the blast furnace produces molten pig iron, which is then converted to steel.

How steel is made in blast furnace?

To make steel,

iron ore is first mined from the ground

. It is then smelted in blast furnaces where the impurities are removed and carbon is added. … About halfway down, limestone begins to react with impurities in the ore and the coke to form a slag. Ash from the coke is absorbed by the slag.

How is iron made in a blast furnace?

Limestone is also

used to remove impurities from the blast furnace

when making iron. The impurities are mostly silicon dioxide (also known as sand). The calcium carbonate in the limestone reacts with the silicon dioxide to form calcium silicate (also known as slag).

Why is coke added to the blast furnace?

Publisher Summary. Metallurgical coke, along with iron ore and limestone, is layered into a blast furnace to

convert the iron ore to metallic iron

. Coke, which is mostly carbon, reacts with the blast air to produce carbon monoxide, which, in turn, reacts with the iron oxide to produce carbon dioxide and metallic iron.

What is added to iron to make stainless steel?

Like all other kinds of steel, stainless steel is made primarily from iron and carbon in a two-step process. What makes stainless steel different is the addition of

chromium (Cr) and other alloying elements such as nickel (Ni)

to create a corrosion-resistant product.
