Product Description of Low Cement Refractory Castable Gunning Mass Ramming Mass For Glass Furnaces And Cement Kilns:
The gunning mass 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.
Features of Rongsheng Factory Supply Refractory Gunning Mass:
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.
Çelik endüstrisi,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.
Ramming Mass:
Ramming mass is made by mixing refractory aggregate, powder, binder, additive with water or other liquids with certain grading. According to the material classification, there are high alumina, clay, magnesia, dolomite, zirconium and silicon carbide carbon refractory ramming materials.
Ramming mass have good chemical stability, erosion resistance, abrasion resistance, spalling resistance, heat shock resistance.
Widely used in metallurgy, building materials, non-ferrous metal smelting, kimyasal endüstri, machinery and other manufacturing industries.
Acidic, neutral and alkaline ramming materials are widely used in coreless medium frequency furnaces and cored induction furnaces.
Ramming Mass mainly used for furnace lining of boiler, blast furnace, hot blast stove, heating furnace, ceramic kiln and various industrial furnaces. Applicable to all kinds of carbon steel, low manganese steel, alloy steel, alloy cast iron, high-speed tool steel and stainless steel.
Characters of Ramming Mass For Glass Furnaces And Cement Kilns:
1. High refractoriness, high refractoriness under load.
