Refractory Material for Blast Furnace
Blast furnaces are used to smelt iron ore and other material. It takes fuel, ore, and flux, as well as a refractory material, in order to produce molten iron and slag. Blast furnace linings utilize refractory materials that are resistant to high temperatures. In this article, we will examine the different refractory materials used in blast furnaces.
Fireclay bricks are made from clay which is baked at temperatures exceeding 1800°C. The result is a heavy, reddish brown, hardened brick that is resistant to high temperatures, abrasion and erosion. Fireclay bricks are often used for the construction of the inner walls and bottoms of blast furnaces, as well as for the flue and throat of the furnace. They are also used as a part of the blast furnace crown and burner block.
Alumina bricks are also used in blast furnaces. They are highly heat resistant because they are made from a mixture of bauxite and magnesia. This mixture has a very high melting point and can withstand temperatures of up to 1700°C before melting. Alumina bricks are often used to line the walls, hearths and floors of blast furnaces.
Silica brick is a type of refractory material that is made from chamotte and silica. This material has a very high melting point and can withstand temperatures of up to 1600°C before melting. They are light-weight, strong and durable and are often used for the walls, hearths and floors of blast furnaces.
Magnesite bricks are another type of refractory material. This material is made from dolomite and magnesia and has a very high melting point. It is used for the walls, floors and hearths of blast furnaces, as well as for the throat and flue. Magnesia bricks are also used to line the walls of stoves.
Carbon bricks are a type of refractory material that is used in the construction of blast furnaces. They are made from graphite and other combustible materials, and have a very high melting point. Carbon bricks are often used as a part of the blast furnace crown, as well as for the walls, throat and flue.
Ganister is a type of refractory material that is made from ganister, a naturally occurring mixture of sand and clay. This material is extremely durable and can withstand temperatures of up to 1500°C before melting. Ganister is often used for the heart and back walls of blast furnaces.
There are a number of different refractory materials used in the construction of blast furnaces. Fireclay bricks, alumina bricks, silica bricks, magnesia bricks and carbon bricks are all used to form the inner walls, hearths and floors of blast furnaces. Ganister is used for the heart and back walls, and all of these materials are chosen based on their ability to withstand extremely high temperatures. Without these refractory materials, blast furnaces would not be possible.
