Application
Applications for Refractory Ceramic Balls
Refractory ceramic balls are widely used in the following fields due to their excellent properties such as high-temperature resistance, corrosion resistance, wear resistance, and thermal shock resistance:
I. Petrochemical Industry
- Catalyst Supports: Ceramic balls are widely used as catalyst supports in petroleum refining, chemical synthesis, environmental protection, and other fields, such as:
- Catalyst supports in petroleum cracking units
- Catalyst supports in the production of chemical products like synthetic ammonia and methanol
- Catalyst supports in automotive exhaust purification systems
- Packing Materials: Ceramic balls are used as packing materials in towers, reactors, and other equipment to disperse gases and liquids, increase contact area, and improve mass transfer efficiency, such as:
- Packing in distillation towers, absorption towers, and extraction towers
- Packing in reactors
- Filter Media: Ceramic balls are used as filter media to filter high-temperature gases and liquids, removing impurities, such as:
- High-temperature flue gas filtration
- High-temperature liquid filtration
II. Metallurgical Industry
- Heat Storage Media: Ceramic balls are used as heat storage media in regenerative high-temperature air combustion systems to recover and utilize waste heat from high-temperature flue gases, improving energy efficiency.
- Hot Blast Furnace Packing: Ceramic balls are used as packing in hot blast furnaces to heat air and provide high-temperature hot air for blast furnaces.
- Protective Slag: Ceramic balls are used as protective slag in continuous casting processes to protect molten steel from oxidation and improve the quality of cast billets.
III. Environmental Protection Industry
- Flue Gas Desulfurization and Denitrification: Ceramic balls are used as catalyst supports in flue gas desulfurization and denitrification systems to remove harmful gases such as sulfur dioxide and nitrogen oxides from flue gases.
- Wastewater Treatment: Ceramic balls are used as biofilm carriers in wastewater treatment systems to remove organic matter, nitrogen, phosphorus, and other pollutants from wastewater.
IV. Other Industries
- Electronics Industry: Ceramic balls are used for packaging and insulation of electronic components.
- Abrasive Industry: Ceramic balls are used for grinding and polishing.
- Refractory Industry: Ceramic balls are used in the production of refractory bricks and castables.
