| titleOfInvention | Graphite electrode with GHP phi 960-phi 1420mm super-large specification and production method thereof |
| abstract | The invention discloses a graphite electrode with a GHP phi 960-phi 1420mm oversized specification, which is a hollow electrode with a phi 150-phi 300mm and is formed by extrusion molding of a needle coke raw material, and a production method thereof comprises the following working procedures: the method comprises the following steps of a profiling process → a water-cooling drilling process (phi 150-phi 300 mm) → primary roasting → a process of flattening end surfaces and cleaning fillers in holes → a dipping process → secondary roasting → a process of graphitizing in LWG → a machining process. The invention adopts high-quality needle coke raw material, has high electrical conductivity, high thermal conductivity and low thermal expansion performance, and the produced graphite electrode with GHP phi 960-phi 1420mm can bear more than 20A/cm 2 The smelting working current is used for high-efficiency smelting; the invention uses the extrusion forming method to produce the high-quality graphite electrode with the GHP phi 960-phi 1420mm and the super-large specification, achieves the performance indexes of high conductivity, homogeneity, high density, high strength, high thermal stress resistance and the like, and can generate subversive technical breakthrough in the aspects of energy conservation, emission reduction and high-efficiency rapid smelting when being applied to a large-capacity submerged arc furnace. |
