Product Testing Control Technology
Accurately test each graphite electrode and nipple by y using advanced instrument , including the indices of Weight , Length , Diameter , Density , Specific Resistance , Nipple socket inside diameter , outside diameter , taper and so on . We guarantee the qualified rate of the sold product should be 100%.

Precautions For Using Graphite Electrodes
1 . Please refer to current load and density when make a choice of electrode size.
2 . Rain , snow and water should be kept away during the transportation and storage of electrode and pre-dry be before use.
3 . In the process of loading , unloading and transportation , careful handling and special hanger are appreciated in case the damage of thread.
4 . Compressed air should be used to clear the dust from thread of electrode before nipple and electrode be connected , and make sure that nipple and electrode are properly twisted.
5 . If iron nipple are used in hoisting the electrode , to make sure that thread of iron nipple are not deformed , in order to avoid the damage of thread of electrode.
6 . When the electrodes are connected the terminal surface between the electrodes should be integrated closely for certain span with moment spanner.
7 . During the operation , the elevator of arc furnace should be stable , so that the situation of electrode joints be loosened or dislocated can be avoided.
8 . The electrode clasper must be within the safety line during the operation.
9 . To prevent breakage of electrode from scrap cave - ins , the electrode should be up or down according to the melting condition and push the UN-melted waste steel to the furnace pond.
10 . To have a good effects of dislocation protection , graphite pin and plug are available in our company , and it s convenient for use.
11 . Before the use of anti-oxidation electrode , to make sure a good connection , the material that separated from the socket should be cleared away.
