Dear user:

We appreciate your choosing the Graphite electrodes produced by “JiangLong”,Please read the using guide carefully before using graphite electrodes to ensure the effectivity.

一、             Choosing Graphite Electrode
 Please choose the suitable graphite electrodes grade and diameter according to the capacity of furnace and the matched transformer.(Attch 1)

Remake: the operating current ranges in table 2 are for AC EAF, DC EAF or LF can run at a reasonable higher current level with the electrode.
二、二、Handling and stacking of the electrode
1、Operate carefully when lift and move the electrodes so as to avoid drop and damage caused by the inclining of the electrode.
2、To keep the end face of the electrode and the thread in the socket in a good status, never hook into the sockets on both side of the electrode with metal hooks when moving the electrodes.
3、Carefully lift up and down when load and unload the case with nipples so as to prevent the nipples from clicking against each other and cause damages to the thread of the nipples thereof.
4、Don’t put the electrodes and nipples directly onto the grand, put them onto wooden bars or metal stands instead, collision or sand contamination must be avoided. Don’t take the packing materials away when the electrode and nipples are not going be used. Dust and contaminations to the threads must be avoided.
5、Electrode must be stacked in order in a warehouse; both ends of an electrode stack must be blocked safely so as to avoid collapsing. The electrodes stacks should be lower than 2 meters high.
6、Electrodes in the stacks must be protected away from rains and heavy humidity, wet electrode must be dried before being loaded onto the furnace so as to reduce the risks of cracking and over high oxidization when operation.
7、Nipples must be away from high temperature to prevent the pitch plugs from melting.
