Description of Zirconium Corundum Ramming Mass Ladle EAf Basic Ramming Mass
Ramming mass is composed of refractory aggregate, powder, binder, additives, etc. in proportion. The amount of powder used in the ramming mass is large, while the amount of binder is small. Due to the use of ramming methods for construction, it is called refractory ramming mass.Ramming mass into acid, neutral, alkaline three.
According to material classification, there are high alumina, clay, magnesium, dolomite, zirconium, and silicon carbide carbon refractory ramming mass.
Zirconium Corundum Ramming Mass is a specialized refractory material used in high-temperature applications, particularly in industries where extreme heat and wear resistance are required. It's designed to line the inner surfaces of furnaces, ladles, and other high-temperature vessels.
Features of Zirconium Corundum Ramming Mass Ladle EAf Basic Ramming Mass
(1) It has thermal hardness, peeling resistance, wear resistance, and corrosion resistance.
(2) It has a high operating temperature, generally between 1450 and 1700 ℃.
(3) No slag, fast setting speed, and easy to construct.
(4) Energy saving and durability. Application It is mainly used for lining various industrial furnaces such as boilers, blast furnace iron trenches, converters, ferroalloy electric furnaces, open hearth furnaces, intermediate frequency furnaces, power frequency furnaces, tundishes, electric furnaces, rotary kiln discharge ports, hot blast furnaces, heating furnaces, ceramic kilns, and various non ferrous metal smelting furnaces such as copper, aluminum, and steel.
