Refractory ball,With strong heat storage capacity, refractory balls not only have high temperature resistance, high crushing strength, high refractoriness under load, but also have good peeling resistance, good thermal shock resistance and excellent creep resistance.
Features of Refractory ball:
High temperature stability: Able to maintain structural stability and performance at extremely high temperatures, usually able to withstand temperatures above 1000°C.
Wear resistance: High surface hardness, able to withstand greater wear and impact, suitable for use in areas requiring wear protection.
Chemical stability: Good tolerance to chemically corrosive substances such as acids, alkalis and salts, suitable for harsh chemical environments.
Thermal shock resistance: Able to withstand rapid changes in temperature, not prone to cracks or breakage due to thermal shock.
Good mechanical strength: Sufficient mechanical strength to withstand high loads and impacts.

Applications of Refractory ball:
High temperature furnaces and kilns: used as lining or lining materials in high temperature furnaces and kilns in industries such as steel, electricity, ceramics and cement to protect the furnace
body from high temperature and chemical corrosion.
Smelting furnaces: used in smelting furnaces to provide high temperature protection and wear resistance, ensuring efficient operation and long life of the equipment.
Gasifiers and incinerators: used as linings in gasifiers and waste incinerators to protect the furnace body from damage by high temperature and corrosive substances.
Chemical industry: used in chemical processing equipment to prevent chemical corrosion and improve equipment durability.
Chimneys and exhaust systems: provide fire protection in chimneys and exhaust systems to extend the service life of equipment.
