Q:Which department in the steel plant needs graphite in large quantities?
The variety and specifications of graphite electrodes used in modern EAF steelmaking are mainly determined by the technical parameters of the steelmaking furnace. With the development of EAF steelmaking technology, the steel-making technology is developing towards large scale and ultra high power. The graphite electrode is mainly made of large size graphite electrode and ultra high power graphite electrode.
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 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?
The process of causing a chemical change by passing through a substance. Chemical change is the process in which material is lost or obtained by electrolysis (oxidation or reduction). Electrolysis is performed in an electrolytic cell. The electrolytic cell is composed of two electrodes, yin and Yang, which are respectively immersed in the solution containing positive and negative ions. The current into the negative electrode (cathode), are positively charged ions migrate to the cathode solution, and with the combination of electronic elements, become neutral or negatively charged molecules; negative ion transfer to another electrode (anode), electrons are given into neutral elements or molecules.
Q:How can I electroplate iron? I would like to use graphite as an electrode. Iron is plated on graphite with iron solution, so it can be processed into iron parts. I wonder if it can be done
Iron plating can be, with 2 valence iron, but on the graphite joint force is good, it is difficult to say, electroplating is bad, peeling is also common. Relatively speaking, iron parts on nickel plating is relatively simple, also more applicable
Q:How long is the graphite electrode machining cycle?
The dust produced in the processing of graphite electrode is relatively large, the possible intrusion to the machine tool guide screw and spindle, which requires a corresponding machining device of graphite graphite dust machine, sealing better, because the graphite toxic.
Q:The difference between graphite electrode and graphite rod
The difference between an electrode and a rod is that the electrode has a lead conductor, and the rod is not.
Q:Are graphite and carbon electrodes the same? What kinds of ore furnaces are used?
Graphite electrode should be relatively pure, composed of graphite.
Q:Iron and graphite as electrodes and Nacl as electrolyte solutions. Why do they produce electric current? Graphite and iron react not with solution, can they be connected by wires?
What happens is oxygen etching negative pole: Fe-2e-=Fe2+ positive electrode: O2+2H2O+4e-=4OH-, of course, the current is produced.
Q:The reason why graphite is used as electrode
Graphite is good in plasticity and easier to be machined preciselyGraphite material has the advantages of high processing accuracy and good surface effect, especially in the processing of precise, complex, thin-walled and Gao Ying material mold cavity. Because the cutting resistance of graphite is only 1/5 of copper material, it is easier to do manual grinding and polishing on the operation. There is no burr after graphite processing, and it is easier to realize automatic production. Complex geometric modeling can be realized.
