The selection of carbon graphite mainly needs to consider the following aspects:
Product structure: Carbon graphite is mainly composed of crystalline graphite and amorphous graphite. Crystalline graphite has high electrical conductivity and thermal conductivity, while amorphous graphite has good lubricity and chemical stability.
Appearance and physical properties: High-quality carbon graphite has a black or gray-black appearance, a smooth and flat surface, no cracks, and no impurities. It has high hardness, good wear resistance, and a density of 3.0-3.3g/cm³. In addition, the purity of carbon graphite is also an important indicator, usually expressed in numbers such as 99%, 99.9%.
Purpose: Different types of carbon graphite are selected according to specific uses. For example, when used to manufacture highly wear-resistant materials, products with good wear resistance need to be selected; when used to manufacture seals, products with good lubricity and chemical stability need to be selected.
Selection of carburizer: For carbon graphite carburizer, its raw materials, particle size and strength need to be considered. High-quality raw materials, suitable particle size and strength can ensure the carburizing effect and hardening speed. In addition, the type of carburizer is also important, such as low ash content, high carbon content, etc.
Application areas: Carbon graphite is widely used in many fields. For example, it is used to make graphite crucibles and steelmaking protective agents in the metallurgical industry; it is used to make electrodes and brushes in the electrical industry; it is used as a wear-resistant lubricating material in the machinery industry; it is used to make heat exchangers and reaction tanks in the petrochemical, metallurgical, acid and alkali production industries.
By comprehensively considering the above factors, you can select carbon graphite products that meet specific needs.
