graphite electrodes hp 300
What should I pay attention to when purchasing graphite electrodes hp 300 products?
With the continuous development of my country’s industry, the development of graphite electrodes hp 300 in the market is more and more extensive, and gradually occupy a leading position in the market. However, when choosing the material of graphite electrodes hp 300, how should the correct choice be made? Woolen cloth?
The material of graphite electrodes hp 300 can be divided into different grades according to its particle size. Of course, for users, the selection of the material of graphite electrodes hp 300 is very critical, because it directly affects the speed of electrical processing. According to different processing conditions, choose a good graphite electrodes hp 300 material.
We know that the melting point of graphite electrodes hp 300 is extremely high, because it has extremely high heat resistance, can larger current value, reduce the loss of the electrode, thereby further improving the production efficiency; and when the current value is very small, the electrode’s The loss will increase. When the area remains the same and the pulse width remains the same, the peak current will reach a certain value and continue to increase, and then the process will become unstable. The electrode and the process will produce arc burns, which will greatly reduce the production efficiency.
The larger the current of graphite electrodes hp 300, the larger the pits of the galvanic corrosion, so as the peak current increases, its surface will become rougher and rougher. At the beginning, the thin electrode is almost in point contact with the workpiece to discharge. The small electrode cannot withstand excessive current and is easily damaged. Therefore, the current should be lowered at the beginning, and then the peak current should be increased slowly until the discharge is stable and the processing speed is fast.
The size of graphite particles determines its loss. The larger the particle, the greater the loss, and the smaller the loss, the smaller the loss. At the same time, the graphite particles also determine the roughness of the surface. Therefore, when choosing the graphite electrodes hp 300 material At that time, we must be careful.
