DESCRIPTION
Low cement castable is a high-strength refractory castable that is widely used in furnace lining. It is made from a blend of fine grain materials, silica fume, alumina, and low-cement binder. The low cement content makes the castable more workable and easier to install.
The low cement castable has excellent high-temperature strength and thermal shock resistance, making it ideal for use in various types of furnaces such as cement kilns, aluminum melting furnaces, and petrochemical furnaces.
One of the significant benefits of using low cement castable in furnace lining is the ease of installation. The castable has excellent flow properties, which makes it easier to apply and spread evenly across the furnace lining without the need for extensive vibration or compaction.
Other benefits of using low cement castable in furnace lining include:
1. High strength and durability: Low cement castable has excellent mechanical strength and durability, making it resistant to abrasive wear and thermal shock.
2. Reduced installation time: The workability and flow properties of low cement castable make it easy and faster to install, reducing the installation time and cost.
3. Enhanced heat insulation: The low thermal conductivity of low cement castable makes it an excellent choice for furnace lining insulation.
4. Ability to withstand extreme temperatures: Low cement castable can withstand high temperatures of up to 1800°C, making it ideal for use in high-temperature furnaces.
