graphite electrode for EAF LF

Graphite electrode is a major conduction material used in the electric smelting industry, which has the properties of superior electric conductivity ,thermal conductivity ,high mechanical strength, oxidation and corrosion resistance in high temperature .Graphite electrode is typically used in EAF (for smelting steel),submerged arc furnace (for producing ferroalloy ,pure silicon, phosphor, matte ,calcium carbide ,etc. And electric resistance furnace ,such as graphitization furnace producing graphite electrodes, glass-melting furnace ,electric furnaces producing carborundum, etc.

Graphite electrodes are classified into RP,HD,HP and UHP.

The graphite electrode comprises:

(1) Regular power graphite electrode( RP grade Graphite Electrode) . Graphite electrode with current density less than 17a / cm2 is allowed to be used in common power electric furnaces for steelmaking, silicon smelting and yellow phosphorus smelting.

(2) Oxidation resistant coating graphite electrode. A graphite electrode coated with an anti-oxidation protective layer (graphite electrode anti oxidant). The formation of both conductive and high temperature oxidation resistant protective layer can reduce the electrode consumption (19% ~ 50%), prolong the service life of the electrode (22% ~ 60%), and reduce the electric energy consumption of the electrode. The popularization and application of this technology can bring such economic and social effects as follows: 1. The unit consumption of graphite electrode is less, and the production cost is reduced to a certain extent. For example, according to the consumption of 35 graphite electrodes per week and 165 refining heats of LF refining furnace in a steel-making plant without shutdown in the whole year, 373 (153 tons) electrodes can be saved every year by using graphite electrode oxidation resistance technology, and RMB 2585700 can be saved by RMB 16900 per ton of ultra-high power electrode per year. 2 The graphite electrode consumes less electricity, saves the unit electricity consumption of steelmaking, saves the production cost, saves energy! 3. Because the graphite electrode is replaced less times, the labor amount and risk coefficient of operators are reduced, and the production efficiency is improved. 4 Graphite electrode is a high consumption and high pollution product, which has a very important social significance in the days of promoting energy conservation, emission reduction and environmental protection. This technology is still in the stage of research and development in China, and some domestic manufacturers have begun to produce it. It is widely used in Japan and other developed countries. At present, there are also companies that import the anti-oxidation protective coating in China.

(3) High power graphite electrode (HP grade Graphite Electrode). Graphite electrode with current density of 18-25a / cm2 is allowed to be used in high power electric arc furnace for steelmaking.

(4) Ultra high power graphite electrode( UHP grade Graphite Electrode). Graphite electrode with current density greater than 25A / cm2 is allowed. It is mainly used in ultra high power EAF.

The Incinerated scrap or E46, is the by-product derived from the reprocessing of incinerated domestic waste.
After the combustion process, the furnace output (IBA Incinerator bottom ash) is firstly washed, magnetically separated and screened to separate any no ferrous material.

At a visual inspection, the material is fragmentized, with iron and steel parts, resulting partly cut or in shredded form.
The stock appears heterogeneous and contains all kind of cut or dismantled steel parts such as sheets, bars, frames, wires, bolts and other iron/steel household residues.

The incinerated scrap is eventually oxidized, due to the thermal and cooling treatments, that the material has been submitted to. The burnt scrap also contains minor slag parts, ash and iron oxide, due to the recovery process.
Such components are inherent and adhere to the scrap surface. The total impurities, can be sorted, but not fully removed.

The consignment does not contain any type of arms, ammunition, mines, shells, cartridges, radioactive contaminated, or any other explosive material in any form either used or otherwise.

The collected stock, is stored in open air, on cemented flooring. It can be loaded loose in 20â?? heavy duty container.
