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 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 is the difference between pyridine type nitrogen and graphite type nitrogen?
The fine structure graphite is the raw material used in the production of graphite electrode. The particle size is relatively small, generally below 0.5.
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:What's the use of carbon?
Common power graphite electrode. Allows the use of current density of less than 17A/ cm 2 graphite electrode, mainly used for steelmaking, smelting silicon, yellow phosphorus and other ordinary power furnace.
Q:What about graphite electrodes for steel mills?
For steel and iron alloys, graphite electrodes are used, when powerful currents pass through electrodes into the melting zone of the electric furnace to produce an arcThe electric energy is converted into heat energy, and the temperature is increased to about 2000 degrees, so as to achieve the purpose of smelting or reaction. In addition, the electrolytic goldWhen the magnesium, aluminium and sodium are used, the anode of the electrolytic cell is also made of graphite electrode. The resistance furnace for carborundum is also made of graphite electrode as the burnerConductive material.
Q:Thermal expansion coefficient of graphite
Thermal expansion coefficient (100 degrees Celsius --600 degrees Celsius) diameter 200--500 graphite electrode body is not greater than 2.410 of the negative four times per degree Celsius
Q:Is graphite flammable?Why do I bake pencil cores with a fever that doesn't burn?
The temperature is not enough, the composition of graphite is carbon, of course, flammable, but each kind of object burning point is not the same, the nature of graphite is relatively stable, burning point is very high, cigarette lighter this temperature is certainly not burning up.Useful words, remember to adopt Oh, thank you ~!
Q:Which department in the steel plant needs graphite in large quantities?
For steel and iron alloys, graphite electrodes are used, when powerful currents pass through electrodes into the melting zone of the electric furnace to produce an arcThe electric energy is converted into heat energy, and the temperature is increased to about 2000 degrees, so as to achieve the purpose of smelting or reaction. In addition, the electrolytic goldWhen the magnesium, aluminium and sodium are used, the anode of the electrolytic cell is also made of graphite electrode. The resistance furnace for carborundum is also made of graphite electrode as the burnerConductive material.
Q:The future of graphene
Sensor domain. Graphene due to its unique two-dimensional structure is widely used in sensor, has the advantages of small size, large surface area, high sensitivity, fast response time, fast and easy electron transfer protein immobilization and maintained its activity and other characteristics, can improve the performance of sensor. Mainly used in the production of gas, biological molecules, enzymes and DNA electrochemical sensors. Singapore Nanyang Technology University developed a graphene light sensor sensitivity is 1000 times the ordinary sensor; the Rensselaer Polytechnic Institute developed performance than the existing commercial gas sensor cheap graphene sponge sensor.
