The choice graphite electrode requires attention. When selecting a welding and cutting graphite product, you need to pay attention to the power of the device so that it can be used with one or another diameter electrode. You also need to pay attention to manufacturing materials, as some programs require special additives that are not available in all models. One of the main aspects of selection is the prompt, because the form may depend on its purpose.
Graphite electrodes are characterized by high conductivity, fire resistance, heat and chemical resistance. Graphite electrodes are widely used in metallurgy, chemical industry, shipbuilding and mechanical engineering.
Graphite electrodes are more practical and versatile in the use of wires. They are easier to process than coal and eventually have flexible joints. Choice graphite electrode, the higher the density, the longer the service life. Compared with 1.5 and 1.7 density service life, the experiment proves that the latter is more than twice as much as the former. Secondly, the specification of graphite electrode was developed. Generally speaking, the material layout control of graphite electrode determines the length of its service life.
The main raw material of graphite electrode is crystalline natural graphite, so the graphite electrode keeps the original natural graphite with good thermal conductivity and high temperature resistance.
When the choice graphite electrode is used, the thermal expansion coefficient is small, and it has a certain strain resistance to rapid heat and cold. Secondly, because the model is relatively stable, the electrode has strong corrosion resistance to acid and alkaline solutions, excellent chemical stability, strong applicability of the electrode, and can ensure the purity of the melted material. Finally, during the use of graphite electrode, the strong oxidizing flame should be avoided to spray directly to the electrode, otherwise the electrode raw material oxidation short life.
