Refractoriness refers to the temperature at which a material does not melt or soften at high temperatures. Refractory degree is one of the important indicators to measure the heat resistance of materials. It is usually used to evaluate the heat resistance of refractory materials, ceramic materials, glass materials, etc. Test methods for refractoriness usually include high-temperature thermal expansion test, high-temperature thermal conductivity test, high-temperature tensile strength test, etc. Materials with high refractory resistance are not prone to melting or softening at high temperatures, have good heat resistance, and are suitable for applications in high temperature environments.
What are the main factors affecting refractoriness?
Factors that affect refractoriness include the chemical composition, structure, density, porosity, thermal expansion coefficient, thermal conductivity, tensile strength, etc. of the material. The main factors that affect the refractory degree are the chemical composition, mineral composition and distribution of refractory products. Various impurity components, especially magnesium components with strong flux effects, will seriously reduce the refractory resistance of the product; uneven distribution of components will prevent the formation of ideal high-melting point minerals, which will reduce the refractory resistance of the product, thereby damaging the product. usage performance.
For example, differences in chemical composition will affect the thermal stability of the material, differences in structure will affect the thermal expansion coefficient and thermal conductivity of the material, differences in density and porosity will affect the thermal expansion coefficient and thermal conductivity of the material, and differences in tensile strength. Will affect the thermal stability of the material. Therefore, when selecting refractory materials, these factors need to be considered comprehensively to ensure that the materials have good fire resistance.
Refractory resistance of some raw materials and products:
Refractory resistance is a measure of a material’s ability to resist melting, softening, or losing structural stability in high-temperature environments. The importance of refractoriness is reflected in the following aspects:
Safety: In high-temperature environments, melting or softening of materials may lead to structural damage, fire, or other safety risks. Materials with high fire resistance maintain structural stability and reduce the risk of fires and accidents.
Extended service life: High-temperature environments have a greater effect on corrosion and wear of materials, and materials with high refractory resistance can resist erosion and wear in high-temperature environments, extending the service life of materials.
Improve process efficiency: Materials with high refractory resistance can maintain stability in high-temperature environments, reduce downtime and repair time due to material damage or failure, and improve process continuity and efficiency.
Energy saving: Materials with high refractory resistance can effectively insulate, reduce heat conduction and loss, improve energy utilization efficiency, and reduce energy consumption and costs.
To sum up, the importance of refractory resistance lies in ensuring safety, extending service life, improving process efficiency and saving energy. It is especially important for equipment and structures working in high temperature environments. Therefore, when selecting materials, one needs to consider their refractoriness to ensure that they can meet the requirements in high-temperature environments.
