You must have a question, what is a furnace brick? Furnace brick or refractory brick is used in traditional and industrial furnaces with high temperature degrees. In the following, we will fully examine what this type of brick is, its structure, raw materials, etc., and we will also explain to you all the necessary information
?What is a furnace brick
Furnace brick is a type of brick that is specifically used to build furnaces and thermal equipment. These bricks usually have special characteristics that make them suitable for resistance to heat and harsh conditions of fire and molten materials
These bricks are very resistant to chemical, physical and mechanical changes. Furnace bricks are generally made in yellow and white colors. On average, the weight of each firebrick mold is about 3 kg. Bricks are baked in two special and standard ways
?What is the purpose of making furnace bricks
The main purpose of making furnace bricks is to use them in the furnaces of the cement and steel industry, and by using them, the heat generated from the burning of fuel in these furnaces is not lost and this loss is reduced as much as possible. From this point of view, the insulation property of these bricks is very important and sufficient attention should be paid in their construction. These bricks should not be such that they contaminate the internal materials of the furnaces
Types of furnace bricks
Fireclay Brick—
– This type of brick is made from clay and sand and usually contains silicon and alumina materials.
– It has high resistance to high heat and acids.
Silica Brick–
– This brick is made of high-pressure silicon grains.
– Suitable for use in furnaces with high temperature and environments that require resistance to acids.
Alumina brick (High Alumina Brick)—
– This brick is made from the highest possible percentage of alumina.
– Usually suitable for resistance to very high temperatures.
Acid Brick–
– This type of brick is made of materials such as clay and silicon.
– It is resistant to acids and special chemical conditions.
Dolomite brick (Dolomite Brick)–
– This brick is made of dolomite (calcium carbonate and manganese).
– It has good resistance to heat and temperature changes and high chemical resistance.
Chrome-Magnesite Brick–
– This brick is made from a combination of chrome and magnesite.
– It is suitable for furnaces with very high temperatures
?What are the characteristics of non-burning bricks
Physical characteristics
- There are a lot of resistance to impact. They are heat and cold insulation. They absorb moisture from 5 to 10 percent. Generally, they weigh about 3 kg. 200 to 220 kg / cm2 are resistant to pressure
Chemical properties
Density: according to the amount of weight per unit, which is the same density, the strength and conductivity of the hand is changed. As the density increases, the strength increases, but at the same time, the thermal conductivity increases sharply. Linear rate of change: This change is expressed based on the change in temperature and the corresponding volume expansion and contraction. Apparent porosity: Although the absence of apparent porosity is not required, manufacturers are required to control porosity as much as possible and not allow it to progress. Load softening temperature: The softening temperature, which is a very important parameter of material resistance, acts in such a way that it determines the resistance at high temperatures up to the moment of deformation
Uses of refractory bricks
Due to its slow melting and high temperature tolerance, this product is used in many cases such as the following
- Iron and steel casting industries Glass melting and glassmaking industries Metal melting furnaces Brick kilns charcoal furnace Use in lime and plaster furnaces
