How to choose the right lining material? What factors should be considered? Below, let's take a look!

1, heat resistance

When choosing the lining material, the factor to be considered is the heat resistance. Different stoves have different operating temperatures and heat conduction modes, so it is necessary to choose materials with appropriate heat resistance. For example, high-temperature furnaces require the use of high-temperature refractory materials, while ordinary furnaces can use ordinary refractory materials. In addition, the coefficient of thermal expansion of the material needs to be considered to prevent the lining from deformation or cracking at high temperatures.

2, corrosion resistance

In some industrial areas, the chemical environment inside the furnace may cause corrosion to the furnace lining. Therefore, it is very important to choose materials with good corrosion resistance. For example, in the process of electrolyzing metals, it is necessary to use materials that are resistant to acid and alkali corrosion. In addition, in the production of special alloys and amorphous materials, it is necessary to use materials that are resistant to oxidative corrosion.

3, density and heat transfer coefficient

The density and heat conduction coefficient of the lining material have influence on the energy utilization rate and temperature distribution of the furnace. The selection of materials with appropriate density and low thermal conductivity can improve the energy efficiency of the furnace and the uniformity of temperature distribution.

4, stability and life

The stability and life of the lining material have an important influence on the running stability and service life of the furnace. Choosing materials with good stability and long life can reduce the frequency of furnace lining replacement and the maintenance cost of the furnace.

5. Cost and availability

When choosing a lining material, you need to consider the cost and availability of the material. Some high performance materials may lead to an increase in cost, so it is necessary to choose the right material according to the actual situation.
