Q:National standard for graphite electrodes
Page 7 the international standard specifies the shape, dimensions and tolerances, technical requirements, test methods, packaging, marking, storage, transportation and quality certificates of graphite electrodes. This standard applies to high quality petroleum coke, asphalt, coke as the main raw material, through molding, roasting, impregnation, graphitization and mechanical processing made of, power supply arc furnace as conductive material of ordinary power graphite electrode. Common power graphite electrode GB
Q:Why should graphite paper be placed between the heater and the graphite electrode?
. Different single crystal furnace heaters may be of the same size or may be different. The heater is determined according to the size of the Czochralski single crystal furnace and the parameters of the drawn single crystal, and is generally designed in the form of a parallel circuit, and the following parameters. A heater, the heater, the shape of two inner diameters of three, four, the effective length of the heater heater, the heater piece is five thickness and gives the heater diameter. These parameters are determined according to Czochralski single-crystal furnace parameters and its crystal diameter. The power transformer parameters are mainly based on the single crystal furnace heating power: maximum output power, maximum output voltage and maximum output current, diameter and height of the crucible. The design of the heater has the following steps: 1. Selecting and determining the shape of the heater; the heater is made of high purity graphite; the resistivity of the high purity graphite; the heater is usually made into a cylinder at present.
Q:The future of graphene
Field of semiconductor materials. Graphene is considered to be an ideal material for replacing silicon. A large number of powerful enterprises have developed graphene semiconductor devices. The Han Guocheng Institute has developed a highly stable n type graphene semiconductor that can be exposed to air for a long time. Graphene silicon optoelectronic hybrid chip developed by Columbia University has broad application prospects in optical interconnection and low power photonic integrated circuit. IBM researchers have developed graphene field effect transistors with cutoff frequencies of up to 100GHz, with frequency performance far superior to the cut-off frequency of the most advanced silicon transistors of the same gate length.
Q:Graphite is made of high-strength graphite, it is a kind of graphite grade specification.
Most of the graphite electrodes are cylindrical, but also have square and multi ribbed shapes. Graphite blank refers to the firing of raw materials without processing graphite.
Q:Synthesis techniques of carbon nanotubes
The synthesis techniques of carbon nanotubes are mainly arc method, laser ablation (Zheng Fa) method, catalytic cracking or catalytic chemical vapor deposition (CCVD), and directional control growth method based on various synthesis techniques.
Q:The original battery is not necessary to form the electrode potential? Why can we use graphite as electrode only? No potential difference.
External electronic wire and the directional movement of ions in the solution of the directional movement between the poles of a closed loop, so that the two electrode reaction, electron transfer process, ordered a current converting chemical energy to electrical energy.Attention, here, "the ion does not go ashore, the electron does not enter the water"." That is the external circuit of graphite electrode is composed of electron flow and electrolyte ion flow; graphite electrode is to produce voltage and electrolyte, and to provide or absorb electrons
Q:The graphite electrode made by the machining center adopts cooling method, which is water cooled, oil cooled and blow cold. Which is good?
I had worked on graphite electrodes for 3 years before, and the fact told me that in addition to using the wind to remove the powder, the others were ineffective or disorderly. Because you have to measure size while processing.
Q:After vacuum melting of quartz crucible, there are three graphite electrode rods. What's the adjustment?
The shorter one is the farther away from the other, and the shorter one is the shorter one
Q:What's the purpose of the electrode material?When the electrolytic molten state of NaCl is said, what is the use of the graphite electrode and the iron electrode?
The copper electrode used for finishing size of the copper electrode discharge speed is not fast but spent graphite electrode is relatively smallRequirements of the high surface, the appearance of products are copper electrode discharge processingThe iron electrode is not clear enough to be used
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.
