It can withstand high temperature and has a small coefficient of thermal expansion. It has a relatively small resistance coefficient, which can reduce the loss of electric energy. With small porosity, the heated electrode can be oxidized slowly. With high mechanical strength, the electrode will not break due to the influence of mechanical and electrical loads.
The current is smelted by the electric arc generated by the electrode input into the furnace. The electrode plays a very important role in the whole electric furnace. Without it, the electric furnace cannot play a role. In order to make the electrode work normally under the temperature generated by the arc, it needs to have a high degree of oxidation resistance and conductivity, which is only possible for the electrode made of carbon material, because the carbon electrode can withstand the arc temperature of 3500 ℃ and only oxidize slowly.
Rongxin carbon Group electrode paste is the “research and development base of ferroalloy Association”, and graphite electrode roasted products are the formulation units of industrial quality standards. It has received the honorary titles of “management standard enterprise”, “Henan Quality Supervision qualified enterprise”, “Henan quality trustworthy enterprise” and “Gongyi City supporting excellent and strong enterprise” issued by the Ministry of agriculture, and enjoys a high reputation in the carbon industry.
