Uses of graphite electrodes

Graphite electrode refers to a type of resistant material made by utilizing oil coke and also pitch coke as aggregate as well as coal pitch as a binding agent through resources calcination, squashing and grinding, batching, working, molding, toasting, impregnation, graphitization, and mechanical processing. The high-temperature graphite conductive material is called artificial graphite electrode (graphite electrode for brief), which is different from the all-natural graphite electrode prepared by using all-natural graphite as basic material.

( 1) Made use of an electric arc steelmaking heater

 Graphite electrode materials can be primarily utilized for electrical heating system steelmaking. Electric heating system steelmaking utilizes study graphite electrodes to introduce functioning present right into the furnace The effective existing at the lower end of the electrode can influence arc discharge via these gas atmospheres, and also the warmth produced by the arc is used for smelting. The size of the electrical capacity is furnished with graphite electrodes with various diameters, which can be utilized continually, and the connection between the electrodes versus the electrode joints. Graphite used in steelmaking as an electrode material makes up about 70-80% of the total intake of graphite electrodes in China.

( 2) Utilized in a submerged electric furnace

 It is generally made used to create an iron heating system with ferroalloy, pure silicon, yellow phosphorus, calcium carbide, and also matte. Its particular is that the reduced part of the conductive electrode is hidden in the cost, so along with the heat created by the arc in between the electric plate and the fee, the present goes through the fee At the same time, warm is additionally produced by the electric resistance of the charge. Every lot of silicon takes in 150 kg of graphite electrode, and also every ton of yellow phosphorus consumes 40 kg of graphite electrode.

 ( 3) Make use of a resistance furnace.

 In the manufacturing process, the graphitization heater for graphite product products, the heater and also production of melting technical glass, and the electrical heating system for silicon carbide are all resistance furnaces. The management of the materials in the heater is both a heating resistor as well as an object to be heated up. Typically, the graphite electrode for carrying out is placed right into the furnace headwall at the end of the fireplace, so the carrying out electrode is not taken in continuously.

 ( 4) For processing

 A large number of graphite electrode spaces are likewise made use of to process numerous crucibles, graphite watercraft, hot die spreading molds and also vacuum cleaner electrical heating system heating elements, and also other special-shaped items. For instance, in the quartz glass industry, 10t of graphite electrode space is required for every production of lt electrical combination tube, as well as 100 kg of electrode blank is taken in for every production of lt quartz block. It must also be kept in mind that there are 3 sorts of graphite composite products at high temperatures, including graphite electrodes, graphite molds, and also graphite crucibles. In these three materials, graphite is prone to oxidation as well as burning reactions at high temperatures, causing surface area adhesive. The increased porosity and loosened structure of the carbon layer influence the service life.
