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:Graphite electrode press device
Graphite electrode is mainly in the petroleum coke and needle coke, coal tar pitch as binder, calcination, mixing, kneading, pressing, baking and graphitization, and made the processing machine, is a conductor in an electric arc furnace to form arc release electricity for heating and melting of the charge, according to the quality index level, can is divided into ordinary power, high power and ultra high power.
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: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 graphite can be used as conductive material?
Widely used as electrode, graphite, carbon brush, carbon nanotubes, mercury rectifier cathode, graphite gasket, telephone parts, TV tube coating and so on in the electrical industry. The most widely used in the smelting of graphite electrode, alloy steel, iron alloy, graphite electrode, the strong current through the melting zone, the arc electrode into the electric furnace, the electrical energy into heat, the temperature rises to around, so as to achieve the purpose of melting or reaction. In addition, in the electrolysis of metal, magnesium, aluminum and sodium, the anode of the electrolytic cell is also made of graphite electrode. The resistance furnace used for the production of rigid sand is also made of graphite electrode as the conducting material of the furnace head.
Q:What kind of asphalt is better for natural graphite coating?
Graphite anode is mainly made of petroleum coke as raw material and coal pitch as binder. It is made by calcination, batching, kneading, pressing, roasting, impregnating, graphitization and machining. Conductive anode used for electrolysis equipment in electrochemical industry. Including: (1) anode plate for various chemical industries. (2) all kinds of anode rods.
Q:How large is the permissible overload current per square millimeter of the graphite electrode cross section?
9A/mm2 safety current should be bare overhead, 5A/mm2 is obviously insulation lines, the indoor environment standards.
Q:What is the application of wire cutting with graphite electrode?
Greatly shorten the preparatory time of mechanical processing, and improve the level of automation of the whole process of machining, and also enhance the ability of the manufacturing system to adapt to changes in production conditions.
Q:How can hydrogen be produced by electrolysis of sodium hydroxide with graphite as an electrode?
You can think so, since sodium has been reduced, so there is always an atom is oxidized, it can only be oxygen oxidation reaction
Q:Use of graphite in steelmaking
Graphite can be used as an agent for carburizing in the steel making industry. Carburizing uses a wide range of carbonaceous materials, including synthetic graphite, petroleum coke, metallurgical coke, and natural graphite. Worldwide, the use of graphite for carburizing is still one of the main uses of earth like graphite.
