Carbon paste is conductive materials supplying electric furnace equipment of ferroalloy furnace and calcium carbide furnace ect.It can endure high temperatures, has smller expansion coefficient and resistance coefficient which can reduce the loss of electric.And it has smaller porous ratio,making heated electrode slow oxidation .Higher mechanical strength makes sure that the electrode isn't broken under the influence of machine and electric load.

  The current carries out smelting through arc produced by electrode inputing furnace.The electrode plays an important role in the whole electric furnace.Without electrode,electric furnace can not be used.The electrode only made of carbon having property such as high oxidative resistance and  electrical conductivity  can work normally under the temperature produced by arc,because the carbon electrode can only slowly oxidize enduring arc temperature of 3500 degree.
