Low thermal expansion castable is a kind of indeterminate refractory material, mainly made of oxide ceramics and carbide ceramics and other raw materials. It is suitable for the lining of rotary kiln of various heat treatment furnaces, such as heating furnace and even heat furnace.
Low thermal expansion castable is a kind of monolithic refractory material, mainly made of oxide ceramics and carbide ceramics and other raw materials.
Low thermal expansion castables are characterized by low coefficient of linear expansion, good thermal shock resistance and good thermal shock resistance, and are suitable for the lining of rotary kilns of various heat treatment furnaces.
The main characteristic of low thermal expansion castables is their low coefficient of thermal expansion. This means that their dimensional changes during heating and cooling cycles are minimal. By reducing expansion and contraction, these castables help minimize the risk of cracking or failure of the refractory lining.
Low heat expansion castables maintain their physical and chemical properties at elevated temperatures. They can withstand thermal cycling and extreme temperatures without significant degradation or loss of performance.
These castables typically have excellent thermal shock resistance and can withstand rapid temperature changes without cracking or spalling. This property is critical in applications where refractory linings frequently experience temperature fluctuations.
Low thermal expansion castables have good mechanical strength and structural integrity. They can withstand mechanical stresses and thermal expansion and contraction in high temperature environments.
Depending on the specific formulation, low thermal expansion castables are resistant to chemical attack by molten metals, slag and other corrosive substances. This makes them suitable for applications where exposure to corrosive chemical environments is expected.
Low heat expansion castables can be used in a variety of industries including steel, aluminum, cement, glass and petrochemicals. They can be used in furnace linings, kiln linings, combustion chambers and other high-temperature applications where thermal stability and low expansion properties are required.
Low hot expansion castables are usually supplied as pre-mixed dry powders or ready-to-use wet mixes. They can be installed using standard pouring or lancing techniques. The ease of installation makes them convenient and widely available for refractory applications.
