The performance of amorphous refractory materials mainly includes the following aspects:
Basic performance
Fire resistance: Fire resistance refers to the ability of a specimen to resist melting under high temperature conditions. Amorphous refractory materials and their raw materials are aggregates composed of various different compounds, therefore there is no fixed melting point, only a melting temperature range. Its fire resistance is not less than 1580 ℃, which ensures the stability of the material in high temperature environments.
Physical and mechanical properties:
Unshaped refractory materials have good physical and mechanical properties, such as high strength and strong resistance to peeling, which enable them to maintain structural integrity and stability in high-temperature environments.
High temperature performance
Load softening temperature: The load softening temperature refers to the temperature at which a specimen undergoes deformation under constant load under continuous heating conditions. It represents the resistance of materials under the combined action of high temperature and load, and is also an important basis for determining the operating temperature of amorphous refractory materials.
Line change rate (high-temperature volume stability): Line change rate refers to the change in size of a material at high temperatures. The small linear change rate of amorphous refractory materials indicates that they have good volume stability at high temperatures, which is crucial for maintaining the structural stability of kilns and thermal equipment.
Thermal shock resistance: Thermal shock resistance refers to the ability of a specimen to resist rapid temperature changes without damage. During the use of materials, temperature rise and fall are inevitable, which can generate thermal stress. Unshaped refractory materials have good thermal shock resistance and can maintain structural integrity in environments with rapid temperature changes.
Slag resistance: Slag resistance refers to the ability of a sample to resist slag erosion and erosion at high temperatures. In thermal equipment such as smelting furnaces, amorphous refractory materials need to withstand the erosion and erosion of slag, so their slag resistance is of great significance for the service life of materials and the stable operation of equipment.
In addition, amorphous refractory materials also have some other properties:
Strong adaptability: Unshaped refractory materials have strong adaptability, low energy consumption, no need for pre firing, and are not limited by the shape of industrial kiln structures during use. They can be made into any shape. This enables it to be widely used in various complex kilns and thermal equipment.
Good integrity: Unshaped refractory materials can be used as prefabricated blocks or form seamless integral structures, with good integrity. This helps to reduce heat loss in industrial furnaces, save energy, and improve the service life of equipment.
High construction efficiency: Unshaped refractory materials are convenient for mechanized construction, with low labor intensity, simple operation, and high production efficiency. Meanwhile, its finished products are easy to store and transport, enabling mechanized furnace construction and improving construction efficiency.
Unshaped refractory materials have excellent fire resistance, physical and mechanical properties, high-temperature performance, and various other performance characteristics. These properties have made amorphous refractory materials widely used in industries such as metallurgy, chemical industry, and building materials, and have achieved significant results.
