RP 450mm Graphite Electrode

RP 450mm graphite electrode as one of  the diameter dimensions of RP 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.

1. Resistance (≤, µΩ·m):8.5
2. Density (≥, g/cm³):1.53
3. Flexure Strength (≥, MPa):8.0
4. Elastic Modulus (≤, GPa):9.3
5. Ash Content (≤, %):0.5
6. CTE (100 °C – 600 °C) (≤, 10-6/°C):2.9
7. Current Load (A):22000-27000
8. Current Density (A/cm²):13-17

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.

1. Procure quality raw materials;
2. Leading computer batching system;
3. 3500tons extrusion molding machine, with vacuum, synchronous cutting advanced process;
4. Automatic temperature baking system;
5. 20000KVA within string graphite furnac;
6. Precision CNC machining lines.

Jinsh Company built up an integrated system of supervision & control, measuring & testing equipment, and quality assurance from raw materials, semi-finished goods to finished goods. We have gone through the GB/T 19001-2016/ISO 9001:2015 quality system certification. International standard on management has been achieved in production management, quality control, safe opertaion, technology development, occupational health, product sales, logistic statistics and customer service.

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 RP 450mm Graphite Electrode is suitable for electric furnaces with a furnace content of 30 tons~50 tons,and an inner diameter of 4.6m~5.2m.

Graphite electrode nipple is the accessory of the graphite electrode. The continuous uese of electrodes use nipple to connect electrode bodies.

The  suitable nipples of rp 450mm graphite electrode are:

TPI3:

Nipple Designation:241T3N or 241T3L

TPI4:

Nipple Designation:241T4N or 241T4L

We have gone through the GB/T 19001-2016/ISO 9001:2015 quality system certification. International standard on management has been achieved in production management, quality control, safe opertaion, technology development, occupational health, product sales, logistic statistics and customer service.

Graphite is a brittle materail, with limited flexibility. For reducing the consumption & cost, please handle your graphite electrodes carefully.

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.

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.
