Q:MITSUBISHI machine graphite electrode processing, how does not accumulate carbon?

The three is difficult cold start, is sparking difficult, not easy car, and finally the combustion chamber carbon Yan will cause a heavy cylinder knock, low speed and acceleration noise, causing damage to the piston and crankshaft, causing the engine temperature which can seriously affect the automobile safety. Emission standards exceeded, not only through the annual inspection, but also directly aggravate the pollution of the environment

Q:The reason why graphite is used as electrode

Graphite has good thermal stabilityThe softening point of copper in 1000 degrees, easily deformed by heat, the melting point of graphite is 3850 + 50 DEG C, the boiling point of 4250 DEG C, even after the ultra high temperature arc ignition, the weight loss is very small, the thermal expansion coefficient is small. The strength of graphite increases with the increase of temperature, and the strength of graphite is doubled at 2000 degrees centigrade. In comparison, the thermal expansion coefficient of graphite material is only 1/30 of copper material.

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:The difference between graphite electrode and graphite rod

Graphite rod for non metal products, as carbon arc gouging cutting process in an essential pre welding cutting supplies, is composed of carbon and graphite with appropriate adhesive, through the extrusion, the temperature of 2200 DEG C after baking rotary plating a layer made from copper, high temperature resistance, good electrical conductivity, is not easy fracture, suitable for metal cutting into required shape.

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:How long is the graphite electrode machining cycle?

Industrial graphite is hard and brittle, and the tool is worn more seriously during machining. It is generally recommended to use carbide or diamond coated cutting tools. When the graphite is rough, the cutter can be directly worked on the workpiece. When it is finished, it is necessary to use light knife to walk quickly to avoid the occurrence of chipping and chipping

Q:What is the composition of petroleum coke and what is its use?

Medium sulphur and common cooked coke; used in large quantities for aluminium smelting. High sulfur, ordinary coke is used in chemical production, such as the manufacture of calcium carbide, silicon carbide, etc., but also as a metal casting and other fuels. Most of the petroleum coke produced in China belongs to low sulfur coke, which is mainly used for smelting aluminium and making graphite.

Q:Is the anode of electrolytic water suitable for ordinary titanium wires?

The graphite is cheaper and easier to obtain, but the carbon electrodes sold in the general market are not very pure at most times. The experiment is done for a period of time, and the carbon is inexplicably broken, especially if you need to work for a long time. So, if your graphite electrode is of good quality, it's still graphite.

Q:Electrolytic salt water why use iron as a cathode, all with graphite can not?

Although iron and graphite can be used, it is better to use iron as the cathode: 1, because the cathode will be protected when it is electrolytic, that is to say, iron will be protected and will not lose electrons

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

Use a tight filter cloth as an anode pack
