Graphite electrode nipple connect two electrodes when used in a furnace,Website:http://www.stoelectrode.com,to achieve continuous use. In electric arc steel making, as the discharge power and electrode diameter increase, the current intensity and heat increase. That is why now the requirements for electrode connection are turn more stringent.To achieve the ideal electrode connection, we need improve the machine quality for nipples and nipples holes, and improving the nipple material, also need appropriate tightening torque, appropriate pre-tightening force. If the pre-tightening force is too large, it will be easy to break off during operation,and if the pre-tightening force is too small, it will cause that the electrode fall off during operation.
The main role of the graphite electrode is to make the electrodes conductive during the smelting of metal in the electric arc furnace. Due to the increasing proportion of steels smelted by electric arc furnaces worldwide,Website:http://www.stoelectrode.com, the use of electric arc furnaces to smelt steel plates and other secondary steels for smelting are major items for the consumption of graphite electrodes.In addition, graphite electrodes are also used in smelting furnaces for the melting of non-ferrous metals, ceramic products, and even waste
