Q & A

Andalusite is a mineral known for its excellent refractory properties. It has a high melting point, low thermal expansion, and good thermal shock resistance, making it an ideal material for refractory applications. Andalusite is commonly used in the production of refractory bricks, crucibles, and kiln furniture due to its ability to withstand high temperatures and harsh conditions. Its unique crystal structure allows it to transform into different phases when exposed to heat, enhancing its resistance to thermal stress. Additionally, andalusite possesses good chemical stability, which enables it to resist corrosion from acids, alkalis, and slag. Overall, the properties of andalusite make it a versatile and reliable material in the manufacturing of refractories for various industrial applications.

The purpose of sodium silicofluoride in refractory materials is to act as a fluxing agent, promoting the fusion of raw materials at lower temperatures and improving the overall melting and sintering properties of the refractory materials.

Raw materials play a crucial role in determining the resistance of refractory products to molten metal attack. The selection and composition of raw materials directly influence the properties of the refractory product, such as its chemical stability, thermal conductivity, and mechanical strength. By carefully choosing raw materials that are resistant to the corrosive effects of molten metal, refractory products can withstand high temperatures and prolonged exposure to molten metal without undergoing significant deterioration. Additionally, certain raw materials can form protective oxide layers on the surface of the refractory product, acting as a barrier against molten metal attack and enhancing its resistance. Hence, the quality and suitability of raw materials are vital in ensuring the durability and longevity of refractory products in harsh industrial environments.

The main sources of serpentine in refractory raw materials are naturally occurring deposits and mines, where serpentine minerals such as chrysotile are extracted.
