How to choose refractory materials for kiln?

When choosing the 耐火物 for a kiln, there are several factors to consider, depending on the type of kiln, working conditions, and cost. You can consult some professional refractory manufacturers, or find professional technicians. Rongsheng Refractories can provide customers with professional refractory solutions.

Selection of refractory materials according to the type of kiln

Different types of 窯 require different types of refractories. 例えば, for drum kilns, rolling kilns, tunnel kilns and other kilns, different types of refractory materials need to be used to adapt to their special working environment and requirements.

Select according to the working temperature of the kiln

The working temperature in the kiln is usually higher than other equipment, and it is necessary to choose refractory materials that can withstand high temperatures. 例えば, for high-temperature furnaces, high-purity refractory materials, such as zirconia, are required.

Selecting refractory materials considering chemical properties

Various chemical substances may be present in the kiln, and refractory materials need to be selected to be able to withstand these substances. 例えば, kilns containing acidic or alkaline components need to choose acid-resistant or alkali-resistant refractory materials.

Consider physical properties

The refractory materials in the kiln need to have physical properties such as low thermal expansion coefficient, high heat capacity and high thermal conductivity to adapt to the high temperature and thermal expansion changes of the kiln. 加えて, factors such as density, wear resistance and shock resistance of the material need to be considered.
