- Q: How to improve the efficiency of graphite electrode milling, please tell me
- There are many factors that determine the need to continue producing graphite electrodes, so high-speed machining has become a key manufacturing process in the die manufacturing industry. Compared with the time required for the milling of graphite electrodes, the processing of high rigidity hard steel still takes longer. When milling dies, cavities, and complex 3D surfaces on hard steel, radial runout errors and tool deviations often result in fracture of the tool. 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.
- 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 kind of asphalt is better for natural graphite coating?
- Special graphite mainly to high quality petroleum coke as raw material, coal tar or synthetic resin as binder, the raw material preparation, mixing, kneading, pressing, crushing, mixing, molding, roasting, soaking, repeatedly repeated purification and graphitization, and made the processing machine. It is generally used in the aerospace, electronics and nuclear industry sectors. It includes pure graphite, high purity, high strength, high density and pyrolytic graphite.
- 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 much does a graphite electrode cost about a ton?
- And different sizes of prices also change, you simply say you use the environment, that is used in where? And how to use it to tell you the price
- 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: Excuse me, why does the graphite electrode flake when electrolyzed salt water is used?
- For example, according to connection of the electrode, which can be divided into two types of unipolar and bipolar type electrolyzer (see photo). The electrode is connected with the DC power supply parallel polarity monopolar electrolyzer, electrodes on both sides of the same, at the same time as anode or cathode. At the same time as the positive and negative electrode bipolar type electrolyzer ends respectively with DC power supply connected, as anode or cathode. The current through the electrode through the electrolysis cell in series, each side of the intermediate electrode as the anode, the other side is the cathode, so it has a bipolar electrode. When the total area at the same time, the current bipolar type electrolyzer is small, high voltage DC power supply, the required investment ratio monopolar, bipolar type filter press used. The general structure, more compact. But easy to leakage and short circuit, slot structure and operation management is more complex than the monopolar type. The monopolar electrolyzer section is generally rectangular or square, cylindrical covers a large, empty The utilization rate is low and the adoption rate is less
- Q: I remember the more lively metal, the electron?
- C is a salt solution of copper metal because copper is first reduced to a single element on a graphite electrode.Moreover, the addition of dilute sulfuric acid has a H2 emission, then a H of the previous metal.
- 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: How large is the permissible overload current per square millimeter of the graphite electrode cross section?
- 9A/mm2 safety current should be bare overhead, 5A/mm2 is obviously insulation lines, the indoor environment standards.
