Compared with traditional copper electrodes,...Read more -
Why can graphite replace copper as an electrode?
How can graphite replace copper as an electrode? Shared by High mechanical strength Graphite Electrode China. In the 1960s, copper was widely used as the electrode material, with the utilization rate accounting for about 90% and graphite only about 10%. In the 21st century, more and more users be...Read more -
Influence of electrode quality on electrode consumption
Resistivity and electrode consumption. The reason is that temperature is one of the main factors affecting the oxidation rate. When the current is the same, the higher the resistivity and the higher the electrode temperature, the faster the oxidation will be. The graphitization degree of electrod...Read more -
How to choose carburizer ?
According to different melting methods, furnace type and melting furnace size, it is also important to select the appropriate carburizer particle size, which can effectively improve the absorption rate and absorption rate of iron liquid to carburizer, avoid the oxidation and burning loss of carb...Read more -
What is the difference between graphite and carbon?
Difference between graphite and carbon among carbon substances is in the way the carbon forms in each matter. Carbon atoms bond in chains and rings. In every carbon substance, a unique formation of carbon can be produced. Carbon produces the softest material (graphite) and the hardest substance ...Read more -
