What are the specific characteristics of graphite electrodes?
The main advantages of graphite electrodes include good conductivity, strong high temperature resistance, high chemical stability, easy processing and high efficiency. The disadvantages are low mechanical strength, high brittleness, high cost and strict requirements on the processing environment.
Lightweight: The density is only 1/5 of that of copper, which is suitable for large electrode applications and reduces equipment load.
Long service life: better wear resistance than copper, lower loss rate.
Excellent conductivity
The conductivity efficiency of graphite electrodes is second only to metals. They can effectively conduct current in high current scenarios such as electric arc furnace steelmaking to ensure process stability.
Outstanding high temperature resistance
It can maintain structural stability in environments below 3000°C and is suitable for high temperature operations such as metallurgy and chemical industry.
Strong chemical stability
It has high tolerance to corrosive substances such as acids and alkalis.
Low thermal expansion coefficient
Small deformation due to heat, which helps to maintain processing accuracy.
Processing efficiency advantage
The cutting speed is 2-3 times faster than that of copper electrodes, and no additional manual processing is required, which greatly shortens the manufacturing cycle.The discharge processing speed is 58% faster than copper, which significantly reduces production costs.
