- Q: What are the factors affecting the service life of graphite electrode in ultra high power arc furnace?
- China's graphite electrode quality standard (YB/T4090-2000) to evaluate the quality of the ultra high power graphite electrode is defined 6 physicochemical indexes, including resistivity, flexural strength, elastic modulus, bulk density and linear expansion coefficient as the quality evaluation index, ash as a reference index.
- 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: Use of graphite in steelmaking
- Application of graphite electrode in smelting, 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 2000 degrees Celsius, so as to achieve the purpose of melting or reaction.
- Q: MITSUBISHI machine graphite electrode processing, how does not accumulate carbon?
- Carbon deposition can cause insufficient combustion of gasoline and cause engine chattering.
- Q: How does graphite produce solar cells?
- Gerrit J said: "despite the modifications, but the inherent nature of graphene remains unchanged, is a significant advantage of composite materials."
- Q: Classification of graphite electrodes
- 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 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: Why is graphite a negative pole and copper is an anode?
- Electrolysis (Electrolysis) is the current through the electrolyte solution or molten electrolyte (also called electrolyte), caused by the redox reaction in the cathode and the anode, the electrochemical cell can occur when an external DC voltage in the electrolysis process.
- 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 do carbon products include?
- Carbon products can be divided into graphite electrode, carbon block, graphite anode, carbon electrode, paste, electric carbon, carbon fiber, special graphite, graphite heat exchanger and so on according to the use of products. Graphite electrode class can be divided into ordinary power graphite electrode according to the allowable current density.
