Gunning mixes are composed of high-quality refractory aggregates, binders, and additives that provide excellent thermal stability and mechanical strength. These materials are designed to be applied using a pneumatic gunning process, which allows for rapid and even distribution. The mix is typically supplied in powder form, which can be easily mixed with water on-site to achieve the desired consistency. Once applied, the gunning mass quickly sets and hardens, forming a durable and heat-resistant layer. Its ability to withstand extreme temperatures and harsh operating conditions makes it an ideal choice for industries requiring robust and reliable refractory solutions.

Product Usage:
Refractory gunning material is an unshaped refractory material that prolongs the service life of kilns and reduces the user's expenditure on refractory materials. After spraying on major kilns and thermal equipment, the use effect is very significant.
Refractory Gunning Mix is mainly used to repair the lining of kilns or thermal equipment, blast furnaces, hot blast furnaces, tap ditch, open hearth furnace, converter and electric furnace, heating furnace, flue, chimney, etc., such as RH furnace dip pipe, ladle, hot metal ditch, etc.
Product Advantages
high refractoriness
Gunning mixes are formulated to withstand temperatures up to 1800°C, ensuring they remain stable and durable in high-temperature applications.
01
Quick Application
The pneumatic gunning process allows for rapid application, reducing installation time and labor costs.
02
Strong Adhesion
The mix provides excellent adhesion to existing refractory surfaces, ensuring a strong bond and long-lasting repair.
03
Thermal Shock Resistance
Gunning mass mixes are designed to resist thermal shock, maintaining their integrity under rapid temperature changes.
04
Chemical Stability
These materials are resistant to chemical attack, making them suitable for harsh industrial environments
05
Product technology:
Key steps include:
The process begins with the selection of refractory aggregates, such as fireclay, silica, and alumina, which are ground into fine powders. These aggregates are then mixed with binders and additives, such as calcium aluminate cement and plasticizers, to enhance the material's workability and durability. The mixture is carefully formulated to ensure optimal plasticity and refractoriness. The final product is thoroughly tested to meet industry standards and specifications. The gunning mix is typically supplied in powder form, which allows for easy transportation and storage. On-site mixing with water ensures that the material achieves the desired consistency for application.
