1700c Heat Resistant Refractory Gunning Materials Low Cement Castable Magnesia Gunning Mix

Product Description

1700C heat resistant refractory gunning materials low cement castable magnesia gunning mix

The 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 mass include silicon aluminum, magnesium, corundum, and phosphate. It is also divided into lightweight,medium heavy weight and heavy weight gunning mass.

Light weight gunning mass is used for thermal insulation and insulation lining, medium heavy weight can be used as both thermal insulation and working lining for medium and low temperature furnaces, heavy weight gunning mass is mainly used as working lining.

Gunning Mass Features:

It 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.


Gunning Mass Application:

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.
