Introduction to Refractory Gunning Materials

Refractory gunning materials play a crucial role in high-temperature industrial environments, providing essential protection to furnaces and kilns. Developed by Rongsheng Kiln Refractory Materials Co., Ltd., these materials are engineered to withstand harsh conditions while ensuring durability and efficiency.

Key Features of the Materials

One of the standout features of these refractory gunning materials is their low impurity content. With minimal levels of Fe2O3, CaO, Na2O, and K2O, they exhibit exceptional medium to high-temperature refractoriness and stability. Furthermore, they possess a low rebound rate, approximately half that of standard spraying materials, which significantly enhances the effectiveness when repairing refractory linings.

Efficiency in Construction

The drying time for these gunning materials is around half that of traditional castables, leading to shortened construction cycles. With adjustments, the construction equipment can accommodate these materials using standard spray machines, allowing for continuous spraying with minimal human error. An average application speed of 2 to 3 cubic meters per hour is achievable, coupled with the added benefit of setting up non-perforating maze-like expansion joints.

Ideal Applications

These high-performance refractory gunning materials are particularly suited for a variety of high-temperature applications including:

• Fluidized Bed Boilers
• Sulfur Burning Furnaces
• Waste Acid Cracking Furnaces
• Gypsum Calcination Furnaces
• Smelting Furnaces
• Heating Furnaces
• Cyclone Dust Collectors
• Hot Air Ducts

Conclusion

With excellent formulation and performance, Rongsheng's refractory gunning materials offer industrial clients efficient and reliable high-temperature protection solutions. These innovative materials are a testament to advancements in refractory technology, catering to various industrial needs while maintaining high standards of quality.
