Q:What are the factors affecting the service life of graphite electrode in ultra high power arc furnace?
The ultra high power graphite electrodes produced in China are 300mm, 350mm, 400mm, 450mm, 550mm, 600mm, 650mm, 500mm and 700mm, with lengths of 1600mm, 1800mm, 2000mm, 2200mm, 2400mm and 2700mm.
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.
Q:What are pyrolytic graphite electrodes used for?
Discharge consumption; because the spark oil also contains C atoms in the discharge process, high temperature oil spark decomposition of C atom, and form a protective film on the surface of the graphite electrode, graphite electrode loss compensation.
Q:MITSUBISHI machine graphite electrode processing, how does not accumulate carbon?
The impact of carbon on the car is quite large, first of all, to reduce the power of the engine, that is, to make the power output uneven and gradually attenuated, in other words, more and more lack of force. Two is to increase fuel consumption, increase your financial burden.
Q:Graphite electrode press device
Ultra high power graphite electrodes. Use of graphite electrodes with a current density greater than 25A / cm 2. Used primarily in ultra high power arc furnaces
Q:Classification of graphite electrodes
A graphite electrode with a current density of 18~25A/ cm 2 is used, which is mainly used in steel-making of high power arc furnace.
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: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.
Q:What are the factors that affect the electrode wear rate of machine tools?
Effect of peak pulse current on electrode wear. The peak current has a great influence on electrode wear, but the curves are very different due to the different materials of the electrode and the workpiece. In the copper electrode machining steel, general peak current, electrode loss is also large, but also have a great relationship with the pulse width, so in practice, we should choose different peak current of different area according to the data processing technology of power supply and discharge pulse width, can make the processing speed is high, and the electrode loss small.
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.
