Q: Classification, uses and manufacturers of graphite electrodes: Classification of graphite electrodes:(1) common power graphite electrode (RP), (2) high power graphite electrode (HP), (3) quasi ultra high power graphite electrode (SHP), (4) ultra high power graphite electrode (UHP) Note: poly carbon classification method

Q: How to improve the efficiency of graphite electrode milling, please tell me: When the tool is broken, it will not only stop the continuous processing of the steel, but also affect the quality of the product, which will lead to the scrap of the parts and the waste of the material. Considering the foreseeable future, the graphite electrode will occupy a high position, usually used equipment for processing graphite electrode the highest efficiency mold manufacturers will unremittingly, expand and between those determined to use the hard steel processing manufacturer competition gap. The foundation of micro cutting tools, in terms of graphite electrodes, is one of its most magical words: "high speed."". The spindle speed of the high speed machining center is up to 30000~60000r/min, and the feed speed can be increased to shorten the processing period and improve the quality of the surface and edge. The motor needed to drive this type of spindle is relatively small and light, which helps to reduce cutting power and reduce tool breakage. This is critical because many of the electrodes are complex, and their production involves small, easily broken micro tools (see Figure 1).

Q: What is the graphite furnace electrode with a diameter of 400?: The variety and specifications of graphite electrodes used in modern EAF steelmaking are mainly determined by the technical parameters of the steelmaking furnace.

Q: Is the anode of electrolytic water suitable for ordinary titanium wires?: Graphite firstFirst of all, the titanium electrode is usually not pure titanium, it should be titanium with a metal oxide coating. Secondly, the advantages of the titanium electrode is mainly to save electricity, the corrosion resistance of carbon is much stronger than that of industrial production, if the meaning is relatively large, but it is still in laboratory experiments, electrolysis of water, not what meaning.

Q: What kind of asphalt is better for natural graphite coating?: Main types of graphite electrode with 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: National standard for graphite electrodes: The national standard normal power graphite electrode graphite electrode: the standard name standard classification number Q51 Standard No. YB/T 4088-2000 for YB/T 4088-2000 YB/T 4088-1992 2000/12/1, instead of the execution time of 0:00:00 release time 2000/7/26 0:00:00 adoption situation

Q: Graphite powder produced by graphite electrode and what we usually call graphite is a kind of thing?: Coal tar pitch as binder is made by calcination, batching, kneading, pressing, roasting, graphitization and machining

Q: How should carbon deposits be treated?: At certain temperature, can make alloy and carbon can react in the engine surface coated with a layer of graphene film, graphene nano particles can fill the pores, wear scratches, on the friction surface repair function.

Q: After vacuum melting of quartz crucible, there are three graphite electrode rods. What's the adjustment?: Or did you adjust the electrode when it was installed? There are two electrode distance, two away, causing melting after different lengths.

Q: What are pyrolytic graphite electrodes used for?: In 1960s, copper is widely used as electrode material, usage rate of about 90%, about graphite only 10%; in twenty-first Century, more and more users start using graphite as the electrode material, in Europe, more than 90% above the graphite electrode material is. Copper, the once dominant electrode material, has almost lost its advantages over graphite electrodes.
