Q & A

How are refractory materials chosen for lining cement kilns and other high-temperature equipment?

Refractory materials are chosen for lining cement kilns and other high-temperature equipment based on their ability to withstand extreme temperatures, resist chemical reactions, and have good thermal conductivity. Factors such as the type of fuel used, the operating temperature, the presence of corrosive substances, and the desired service life are considered when selecting refractory materials. Additionally, the material's mechanical strength, thermal shock resistance, and ease of installation are also taken into account for optimal performance and cost-effectiveness.

What is zirconia, and how is it used in refractories?

Zirconia is a white, crystalline oxide of the metal zirconium, known for its high melting point and excellent thermal and chemical stability. It is commonly used in refractories, which are materials designed to withstand high temperatures and harsh environments. In refractories, zirconia is used as a key component due to its ability to enhance the mechanical strength, thermal shock resistance, and corrosion resistance of the material. Its refractory properties make it ideal for lining furnaces, kilns, and other high-temperature industrial applications.

How is carbon processed and shaped for refractory applications?

Carbon is processed and shaped for refractory applications through a series of steps. Firstly, raw carbon materials such as petroleum coke or coal tar pitch are selected and crushed into smaller particles. These particles are then mixed with binders and additives to form a carbon paste or slurry. This paste is then shaped into the desired form using various techniques like extrusion, molding, or casting. After shaping, the carbon products are subjected to a heating process called carbonization, which removes volatile components and strengthens the structure. Finally, the carbon products undergo a graphitization process, where they are heated at high temperatures to transform the carbon into a more crystalline structure, improving its refractory properties.

What are the thermal properties of refractory raw materials?

The thermal properties of refractory raw materials refer to their ability to withstand high temperatures without undergoing significant changes in their physical or chemical properties. These materials typically have a high melting point, low thermal conductivity, and excellent thermal shock resistance. They also exhibit minimal expansion or contraction when subjected to extreme temperature fluctuations. These properties make refractory raw materials suitable for applications in industries such as metallurgy, glassmaking, and ceramics manufacturing, where they are used to line furnaces, kilns, and other high-temperature environments.
