Product Description

 

 

Graphite Electrodes are a high temperature resistant graphite conductive refractory material used in the metallurgical industry. Graphite Electrodes are made of petroleum coke, bituminous coke as aggregates, coal tar pitch as binders, after raw material calcination, crushing and milling, batching, kneading, molding, roasting, impregnation, graphitization and machining, which are also known as artificial graphite electrodes in order to distinguish from natural graphite electrodes made of natural graphite.
Notice : How to Use Graphite Electrode

Be careful when transporting and pilling electrodes with forklift and avoid of collision. One layer of goods at a time; notice the balance and alignment and avoid falling or breakage.

When loading and unloading with forklift, wire rope must be used and steel wrapping tape cannot be employed directly to fetch electrodes.

> Electrode should be stored in clean and dry place. When pilling up outdoors, it should be covered with rain-proof tarpaulin and the number of piling layers ought not to exceed four.

> When using electrodes, special tools should be employed to cut the steel wrapping tape, and crane should not be adopted to avoid bursting.

> Steel-wire ball, metallic brush or emery cloth is not allowed for cleaning the electrode thread, but compressed air free of oil and water is available.

> Use revolved resilient hanger and put soft truss pad under the electrode joint to avoid breakage of the thread.

> Lift the electrode to the furnace by using a hoister with resilient hangers, and find out the center and move slowly downwards, screw and tight with a hoop.

> If the two poles of the two electrodes are untouched or touched in overpressure, this may cause bad effect.

> In order to avoid electrode breakage, put the large materials in lower part and small materials in the upper part.
