Electrode paste index of energy chemical industry

  Electrode paste is a conductive material used for electric furnace equipment such as ferroalloy furnace and carbide furnace.

  It can withstand high temperature and has a small coefficient of thermal expansion. It has a relatively small resistance coefficient and can reduce the loss of electric energy. It has a small porosity and can slow the oxidation of the heated electrode. With high mechanical strength, the electrode will not be broken due to the influence of mechanical and electrical loads.

  The current is input into the furnace through the electrode to generate an arc for smelting. 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 high oxidation resistance and conductivity. Only the electrode made of carbon material has this property, because the carbon electrode can withstand the arc temperature of 3500 ℃ and only slowly oxidize.
