Directions for Use Graphite Electrodes

1.When the graphite electrodes are selected for electric steel furnace,reference is made to the currentcarrying capacity of the electrodes.
2.The transport and storage of the graphite electrodes must be kept away from being moistened or weted by rain ,snow,andwater.Be sure to dry up before use
3.During loading,unloading andtransportation,the graphite electrodes must be handled with great care to protect the threads from being damaged by collision. In the course of loading ,unloading and hoisting ,it is advisable to use special hoist tools.
4.Before the electrodes are connected to the nipple,it is necessary to below the electrode threads  throughly clean with compressed air and screw the nipple tightly then into the eletrodes.
5. The terminal faces of the two electrodes tightly screw-connected must be kept in close contact.
6.When the elevator of the electric are furnace is hoisting the electrodes, no swing is allowed so as to avoid the electrode joints being loosened and dislocated.
7.The tighting devices of the electrodes must not hold the electrode near the area of the nipple sockets.
8. In order to prevent the breakage of the electrodes in case of scrap cave-ins,lift the electrodes in time according to the melting condition and dump the unmelted waste steel into the pool.
9. Charging the furnace,put the large scrap steel lumps at the buttom and the small ones at the top .
10.In order to prevent dislocation after the electrodes being joints, we provide binding paste and pins which is easily to be applied.
