Q & A

What is the purpose of low-thermal-expansion materials in enhancing refractory durability?

The purpose of low-thermal-expansion materials in enhancing refractory durability is to minimize the adverse effects of thermal stress and thermal shock on the refractory material. By having a low coefficient of thermal expansion, these materials are able to withstand repeated heating and cooling cycles without undergoing significant expansion or contraction. This helps to prevent cracking, spalling, and other forms of damage that can occur due to thermal stress, thereby increasing the overall durability and lifespan of the refractory material.

How does silicon carbide nanoparticles enhance the properties of refractory materials?

Silicon carbide nanoparticles enhance the properties of refractory materials by improving their mechanical strength, thermal conductivity, and resistance to high temperatures. The addition of silicon carbide nanoparticles to refractory materials enhances their overall performance and durability, making them more effective in withstanding extreme conditions such as high temperatures and thermal shocks. The nanoparticles also contribute to reducing the material's vulnerability to thermal expansion and enhance its resistance to chemical corrosion. Overall, the incorporation of silicon carbide nanoparticles enhances the properties of refractory materials, making them more suitable for applications in industries such as metallurgy, ceramics, and aerospace.

What are the different grades of magnesia used in refractory applications?

There are typically three grades of magnesia used in refractory applications: dead-burned magnesia (DBM), fused magnesia (FM), and caustic calcined magnesia (CCM). Each grade has different characteristics and is suitable for specific refractory requirements. DBM is produced by heating magnesite ore at high temperatures, resulting in a dense and chemically stable product. FM is made by melting magnesite in an electric arc furnace, resulting in a high-purity, high-density material with excellent corrosion resistance. CCM is produced by calcining magnesite with caustic soda, resulting in a reactive and high-purity product suitable for certain refractory applications.

Which refractory raw materials are commonly used in the petrochemical industry?

Some commonly used refractory raw materials in the petrochemical industry include alumina, silica, magnesia, and chrome oxide.
