How to choose high-temperature castable?

Selecting suitable high-temperature castable needs to comprehensively consider multiple factors such as working temperature, chemical composition, physical properties, wear resistance, construction methods, budget, and supply reliability, so as to ensure that the selected castables can perform well under specific conditions And has a long service life.

How to choose high-temperature castable？

Operating temperature

First of all, it is necessary to determine what kind of working temperature environment the refractory castable will be used for. Different castables are suitable for different temperature ranges, ensuring that the selected castables can maintain stability and durability at the expected working temperature.

Chemical composition

The chemical composition of a refractory castable directly affects its performance and durability. According to the application requirements, select the appropriate chemical composition, such as oxides, nitrides, carbides, etc., to ensure that the castable can effectively resist corrosion and wear under specific conditions.

Physical properties of high-temperature castable

Consider physical properties such as density, thermal conductivity, and thermal expansion coefficient of castables to ensure that they can work in harmony with other materials in actual use and avoid problems caused by mismatching physical properties.

Wear and Corrosion Resistance

According to the actual use, choose refractory castables with sufficient wear resistance and corrosion resistance, especially in high-temperature and corrosive environments.

Construction method

Different refractory castables may require different construction methods, including vibrating, pouring, spraying, etc. Make sure that the castable selected is suitable for the desired method of construction.

Budget considerations of high temperature castable

The price of refractory castables varies by type, performance, and source of supply. Consider choosing a castable with suitable performance according to the budget, and also consider its service life and maintenance cost.
