Superior properties of refractory spray castables

Refractory spray castable is a high-performance material designed for high-temperature environments. Its low impurity content and medium- to high-temperature refractory properties make it excellent in a range of high-temperature industrial applications. This material has the following notable properties:

low impurity content

The impurity content of refractory spray castables is strictly controlled during the production process to ensure the purity of the material. This feature not only improves the material's high-temperature fire resistance, but also extends its service life.

Medium and high temperature fire resistance

Refractory spray castables can maintain stable chemical and physical properties in medium to high temperature environments. Experiments have proven that this material has excellent volume stability and thermal shock resistance at high temperatures of up to 1,600 degrees Celsius , and is adaptable to various complex industrial furnace environments.

Optimize construction process and oven time

Compared with other materials, refractory spray castables exhibit extremely low rebound rates during construction, which significantly improves construction efficiency and reduces material waste. In addition, thanks to its high-performance properties, oven times can be significantly reduced, speeding up repair and maintenance processes. These factors make it ideal for industrial furnace lining repairs.

Low construction rebound rate

Construction rebound rate is an important indicator of the efficiency of injection cast materials. Refractory spray castables perform excellently in this aspect and rarely rebound during construction, saving material and labor costs.

Reduce oven time

The application of refractory spray castables can significantly shorten the oven time, reduce production downtime, and improve overall operating efficiency. Current data shows that the oven time can be reduced by approximately 30% after construction using refractory spray castables.

Wide range of applications in high temperature industry

Thanks to its many superior properties, refractory spray castables are widely used in high-temperature industries, especially in the following aspects:

• Metallurgical industry: used for lining repair and maintenance of various high-temperature furnaces.
• Petrochemical industry: lining protection for high temperature reactors and cracking furnaces.
• Electric power industry: suitable for repairing high-temperature parts of power plant boilers.

All in all, refractory spray castable is an indispensable high-performance material in high-temperature industries. Its low impurity content, medium and high temperature refractory properties, low construction rebound rate and reduced oven time make it an excellent application prospect in repairing and maintaining industrial furnace linings.
