Application of graphite balls
Graphite balls are widely used in many fields, mainly including metallurgical industry, wear-resistant materials, seals and lubricants. Graphite balls are widely used in many fields, mainly in electronics, information, biology, materials, energy, aerospace, military industry and technology.
In the metallurgical industry, graphite ball carburizer is an environmentally friendly smelting carburizer product, mainly used to increase the carbon content in steel. It is made of natural graphite ore through ball milling, flotation, purification, bonding, curing, drying and packaging, and is in the shape of black oil hemisphere. The use of graphite ball carburizer can reduce the manufacturing cost of steel, improve the performance of steel, promote the growth of crystallizer in steel, and increase the grain fineness. Application in wear-resistant materials
Graphite balls with high hardness are widely used in metallurgy, machinery, chemical industry and other industries, and their surface is flat or circular with a slight arc. This material can withstand various physical and chemical erosions in the air for a long time without being damaged, so it is also used in seals and lubricants. Application in steelmaking industry
Graphite carbon balls can be used as carburizers in the steelmaking industry to improve the performance of steel. Under vacuum conditions, the deoxidation capacity of carbon will be greatly improved. Reasonable application can optimize the organizational structure of steel and enhance its strength, toughness, hardness and wear resistance. 3.
In the energy field, graphite spheres have significant energy potential as nuclear fuel. A graphite sphere the size of a tennis ball with a diameter of only 60 mm releases energy equivalent to 15 tons of standard coal, demonstrating the application of digital and intelligent production methods in improving the quality and reliability of nuclear fuel.
The role of graphite balls in glass production
The role of graphite balls in glass production mainly includes the following aspects:
Prevent glass liquid from bonding with refractory materials: Graphite has excellent thermal and electrical conductivity, which can effectively prevent glass liquid from bonding with refractory materials, thereby reducing the number of failures and repairs in the production process. 1.
Prevent unnecessary convection of tin liquid: In the glass production process, the use of graphite balls can reduce the flow of tin liquid and avoid unnecessary convection, thereby ensuring the quality and production efficiency of glass. 1.
Resistant to chemical corrosion: Graphite materials have good chemical stability, are not easily infiltrated by molten glass, will not change the composition of glass, and ensure the quality and purity of glass. 2.
Thermal stability and resistance to heating shock: Graphite materials have low linear expansion coefficients and good thermal stability, can withstand rapid cooling and heating at high temperatures, and reduce deformation and damage of molds caused by temperature changes. 3.
Lubrication and wear resistance: Graphite material has good lubrication and wear resistance, which can reduce the friction between the mold and the glass liquid under high temperature and high pressure conditions and extend the service life of the mold3.
Easy to process: Graphite material is easy to process and can be made into molds with complex shapes and high precision, meeting the requirements for mold shape and precision in glass manufacturing3.
In summary, graphite balls play a role in preventing adhesion, reducing convection, resisting chemical corrosion, improving thermal stability and wear resistance in the production of glass, significantly improving the efficiency and product quality of glass production.
