Q:Why should graphite paper be placed between the heater and the graphite electrode?

Heater design, the common heater has three shapes, cylinder, cup, spiral, the vast majority of the current heater is cylindrical, as shown in figure. The spiral heater has complicated processing technology and has been eliminated. Cup shaped heater for hemispherical crucible, the bottom melt temperature is more uniform, because the processing technology is difficult, already no use. Nowadays, most of them use cylinder heaters. The cylindrical heater is not only easy to process, but also is related to the large number of flat crucible used in the direct drawing single crystal furnace.

Q:How should carbon deposits be treated?

In this way, can keep the engine seal, to prevent oil because the gap is too large and rampant, buried carbon curse generation "".

Q:The reason why graphite is used as electrode

Graphite is good in plasticity and easier to be machined preciselyGraphite material has the advantages of high processing accuracy and good surface effect, especially in the processing of precise, complex, thin-walled and Gao Ying material mold cavity. Because the cutting resistance of graphite is only 1/5 of copper material, it is easier to do manual grinding and polishing on the operation. There is no burr after graphite processing, and it is easier to realize automatic production. Complex geometric modeling can be realized.

Q:Can Naiduo high temperature graphite

The reinforced graphite gasket is made of flexible graphite tape or flexible graphite and is molded into ring products of different sizes. Suitable for hot water, high temperature, high pressure steam, heat exchange liquid, nitrogen gas, organic solvent, hydrocarbon, low temperature liquid and other medium. Used in compressors, machines, pumps, valves, chemical instruments, instruments, etc..

Q:Why is the production of one ton of ultra high power graphite electrode requires 1.05 tons of coke?

Petroleum coke is divided into needle coke and sponge coke and projectile reef, fixed carbon content components of petroleum coke is around 80%

Q:Why is graphite a negative pole and copper is an anode?

Electrolysis (Electrolysis) is the current through the electrolyte solution or molten electrolyte (also called electrolyte), caused by the redox reaction in the cathode and the anode, the electrochemical cell can occur when an external DC voltage in the electrolysis process.

Q:Why is graphite conductive electrode oxidized?

Graphite electrode uses petroleum coke (carbon), pitch coke (carbon) as granule material

Q:What is the difference between SGL graphite electrode and graphite electrode in general?

Pure graphite is a kind of high-purity graphite. The processing technology of fine graphite and high purity graphite is basically the same, that is, the purity of graphite is different, the purity is higher, and the particle size is basically the same

Q:What are the losses in graphite electrode?

In EDM, discharge principle is to remove the workpiece material by using the tool and the workpiece anode spark discharge explosion, spark discharge is bidirectional, not only will the workpiece removal part, forming processing, will cause some loss of electrode. Electrode loss is one of the main causes of machining errors in machining, and is an important technical parameter affecting the accuracy and quality of EDM

Q:800KVA and 12500 EAF transformer data graphite electrode furnace.

Graphite project: Project Description: steel furnace and iron smelting furnace, ferrosilicon smelting, electrolytic aluminum and so on, all use large surface graphite electrode.
