Method for producing ultra-high power graphite electrode through natural graphite
The invention relates to graphite electrodes, particularly to a method for producing an ultra-high power graphite electrode through natural graphite. Three layers of moulds are utilized. The method comprises mixing needle coke with modified asphalt and adding iron sesquioxide to be heated and stirred, adding the inner layer of electrode mould after the materials are mixed into a paste, performing prepressing and pressing the materials into a cylinder; removing the inner layer mould, mixing the natural graphite with the needle coke, adding the modified asphalt and the iron sesquioxide, performing heating and mixing, adding the second layer of mould, performing pressurization to press the materials and an inner layer of graphite column together after the prepressing and performing cooling; removing the second layer of mould, heating and uniformly mixing the natural graphite and the modified asphalt and the iron sesquioxide, adding the outer layer of mould, performing pressurization after prepressing to press the outer layer of materials and the graphite column formed inside together; removing the mould and performing cooling; placing the cooled graphite electrode into a high temperature furnace to be roasted, feeding the graphite electrode into a graphitization furnace for graphitization and temperature rise graphitization after dipping and obtaining the finished product after cooling and machining. According to the method for producing the ultra-high power graphite electrode through the natural graphite, the processes are reduced and the cost is reduced.
