Cum să alegeți materiale refractare pentru cuptor?

When choosing the refractory materials for a kiln, sunt mai mulți factori de luat în considerare, in functie de tipul cuptorului, conditii de lucru, si cost. Puteți consulta câțiva producători profesioniști de refractare, sau găsiți tehnicieni profesioniști. Rongsheng Refractories can provide customers with professional refractory solutions.

Selection of refractory materials according to the type of kiln

Different types of cuptoare require different types of refractories. De exemplu, 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. De exemplu, 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. De exemplu, 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. în plus, factors such as density, wear resistance and shock resistance of the material need to be considered.
