UHP 700mm Graphite Electrode

UHP 700mm graphite electrode as one of  the diameter dimensions of UHP grade graphite electrodes used for the recycling of steel in the electric arc furnace industry. Its main ingredient is high-value needle coke which is made from either petroleum or coal tar. Graphite electrodes are finished with a cylinder shape and machined with threaded areas at each end. In this way, the graphite electrodes can be assembled into an electrode column using electrode nipple.

In order to meet the requirement of higher work efficiency and lower total cost, large capacity ultra-high power arc furnaces are becoming more and more popular. Because of this, UHP graphite electrodes with diameters of over 500 mm will dominate market.

1. Resistance (≤, µΩ·m):5.5
2. Density (≥, g/cm³):1.68
3. Flexure Strength (≥, MPa):11.0
4. Elastic Modulus (≤, GPa):14.0
5. Ash Content (≤, %):0.2
6. CTE (100 °C – 600 °C) (≤, 10-6/°C):1.5
7. Current Load (A):70000-120000
8. Current Density (A/cm²):18-30

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 UHP Graphite Electrode 700mm is suitable for electric furnaces with a furnace content of 250 tons~350 tons,and an inner diameter of 8.2m~8.8m.

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 uhp 700mm graphite electrode are:

TPI3:

Nipple Designation:317T4N or 317T4L

TPI4:

Nipple Designation:317T4N or 317T4L

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.
