Production Description

Graphite electrode is made from the domestic first petroleum coke and high quality needle coke

and widely used in the electric arc furnaces for production of alloy steels, metal and other

nonmetallic materials, etc. The graphite electrodes include regular power, high power, super high power, ultra high power and square electrode. The range of diameters covers from 200mm to

700mm. Our products own the following characteristics: low electric resistance, good electric and

thermal conductivity, high oxidation resistance, greater resistance to thermal and mechanical shock, high mechanical strength, high machining accuracy.

Applications

Used in EAF and LF for steel making, as well as in electric smelting furnace for producing industrial silicon, phosphorus, etc.

Programmable properties
1.Good electrical conductivity
2.High resistance to thermal shock
3.High mechanical strength

Grades:RP, RPI, HP, SHP, UHP

Graphite Electrode RP Grade

Q:Why is the production of one ton of ultra high power graphite electrode requires 1.05 tons of coke?: After calcined to eliminate ash and volatile part of the points in this process will be a lot of weight loss, in the process of crushing mixing in process of baking or graphite in high temperature heat treatment, another part of the impurities were excluded, so the raw material is higher than the rate of finished products.

Q:Graphite electrode in milling machine processing, dust is especially big, boot 5 minutes, workshop can not open the figure, what is the solution?: Connect the fan with a thicker pipe and suck it out of the workshop. The air inlet is mounted on the milling head. Reduce milling speed properly.

Q:Will the brush grease not short-circuit the commutator?: The brush of motor is usually made of pure graphite electrode, electrochemical graphite electrode and metal fossil ink electrode material. Because it contains graphite, it has conductive effect on the one hand

Q:Electrolytic salt water why use iron as a cathode, all with graphite can not?: The iron electrode is easier to be installed in the electrolytic cell, which is more convenient than the graphite electrode, and the density of the graphite is small. After being adsorbed by hydrogen, the graphite is easy to float up, and the density of the iron is larger. This problem does not exist in the.5

Q:Why should supercapacitors use graphite as electrode material?: Because graphite material, light weight, good thermal conductivity and conductivity.

Q:Do electroplating experiments, graphite as an electrode, graphite how to pre process to ensure that the coating will not fall, resulting in increased color of the solution: Both of these will be a little bit absorbed, when plating, the anode and anode inside the syrup will run on the negative pole,

Q:Synthesis techniques of carbon nanotubes: Carbon nanotube discharge using graphite electrode is one of the earliest studies in various synthetic techniques. The researchers did a lot of work in optimizing arc discharge for carbon nanotubes. In recent years, in addition to people by adjusting the current and voltage, pressure and velocity change, change the electrode composition, improved electrode feeding mode optimization of arc discharge process, but also through changes the arc medium, simplified arc device. In the process of preparing carbon nanotubes, arc method is mature by changing the arc discharge conditions, catalyst, electrode size, feed mode, the distance between the poles and the raw materials. The carbon nanotubes formed by arc method are straight and wall (multi wall or even single wall). But the production rate is low, the arc discharge process is difficult to control, and the preparation cost is too high. The industrial scale production needs to be explored.

Q:What is the difference between SGL graphite electrode and graphite electrode in general?: In fact, the graphite electrode abroad (including Japan) in several ways than we can control the fine, one is pure, another is anisotropic (resistance, thermal conductivity ah) usually do some control, in the strength of domestic now is also doing well, but when we are comparing high quality products, general domestic products it is basically a piece of the indicators are poor

Q:Graphite electrode press device: Ultra high power graphite electrodes. Use of graphite electrodes with a current density greater than 25A / cm 2. Used primarily in ultra high power arc furnaces

Q:What is the striking electrode in the die making? Where is the technical point?: Technology of EDM should master the characteristics of electric discharge between tool electrode and workpiece is not in direct contact, but there is a gap, the gap is generally between 0.05~0.3mm, sometimes may reach 0.5mm or more, full of fluid, processing by high voltage pulsed discharge, the discharge of corrosion the workpiece.

We enjoy convenient access to major transportation networks. Furthermore, all our products are manufactured with advanced equipment and strict QC procedures in order to ensure high quality.
