Description

The Brife Introduction Of HP 550mm Graphite Electrode

HP 550mm graphite electrode as one of  the diameter dimensions of HP grade graphite electrodes is the conducting element for electric arc furnaces steelmaking. It is made of petroleum coke, needle coke, coal pitch and produced by a series of strict production processes. High-current lines insert through the graphite electrode port inside the furnace body. This will releases electric energy in the arc furnace to heat the furnace.

The demand for the larger diameter electrodes has been increasing as EAF furnace sizes become larger. Graphite electrodes with diameter of 500 mm or 600 mm have become increasingly popular in recent years.

The Production Process Of Graphite Electrodes

Graphite electrode is made of petroleum coke, needle coke and coal pitch, through crushing, calcining, batching, kneading, forming, baking, impregnation, graphitization and machining.

It is a conductor that releases electric energy in an arc furnace to heat the furnace. Mainly used in electric oven. For example: like smelting steel, smeltiing silicon and smelting yellow phosphorus.

Therefore, a strict production system is very important and necessary for the quality of graphite electrodes.

Details Of Quality Inspection And Assurance

Graphite Electrode Selection

Electrode oxidation, sublimation, dissolution, spalling and breaking are all related to the cost of EAF steelmaking. Proper graphite electrode selection, use and maintenance can effectively reduce electrode consumption.

So the HP 550mm Graphite Electrode is suitable for electric furnaces with a furnace content of 120 tons,and an inner diameter of 6.7m.

Package And Transportation

Nominal package type

Electrodes are placed upon wooden pallet and braced strongly with high quality steel tape to be suitable for land and sea transportation. Nipples are packed in crates.

Pre-set package type

Assembled electrodes and nipples are packed in crates. Caps protect nipples and sockets with polyester. Keep the protective caps at each end in place and undamaged, this can protect the threads from damage by bumping and other abrasions.
