Product Description
Refractory Gunning Mix:
Gunning mix is composed of refractory aggregate, refractory powder, water, binder, mineralizer, plasticizer, and firing aid. It is a fire-resistant mixture constructed by spraying method.The materials of gunning mix include silicon aluminum, magnesium, corundum, and phosphate. It is also divided into lightweight,medium heavy weight and heavy weight gunning mix.
Light weight gunning mix is used for thermal insulation and insulation lining, medium heavy weight can be used as both thermal insulation and working lining for mediuContact Usm and low temperature furnaces, heavy weight gunning mix is mainly used as working lining.
Features and Advantages of Refractory Gunning Mix
refractory gunning mix has the characteristics of high adhesive rate,less resilience,high strength and easy gunning etc.scour resistance,impact resistance,erosion resistance.anti-scouring, wear resistance and excellent performances.
Application
Application of Refractory Gunning Mix
Steel Industry,Energy Industry,Building Materials.It serves as a protective layer on the inner surface of blast furnace and hot blast furnace shells, as well as a working lining for blast furnace heads, coal gas outlet pipe, and dust collectors.
