eaf thread electrode
What are the graphitization systems of CGM eaf thread electrode?
What are the graphitization mechanisms? Relating to the makeover device of carbonaceous products in the electrode graphitization procedure, as the understanding strengthens, there are various theories, among which the following are depictive:
( 1) Carbide conversion theory. Carbide conversion concept thinks that the graphitization of carbonaceous products is first with the development of carbides with different minerals (such as 203, as well as), and after that disintegrates right into steel vapor and also eaf thread electrode at heats. This theory is appropriate for the decomposition of eaf thread electrode, but it is obviously not true for electrode graphitization of the majority of carbon materials.
( 2) Recrystallization concept. The recrystallization concept thinks that the graphite crystals present in the carbonaceous raw materials are “welded” with each other to form larger graphite crystals via the displacement of carbon atoms throughout the graphitization process; the new crystals take in international carbon at the get in touch with user interface of the original crystals. The degree of graphitization is associated with the growth of crystals, however generally relies on the graphitization temperature; the problem of graphitization is related to the architectural properties of the carbonaceous product; the size of graphite crystals raises as the temperature level rises, however It’s simply a quantitative modification, not a vital adjustment. This concept explains to a specific level the connection between crystal growth and also graphitization temperature level, as well as the influence of basic material buildings on the degree of graphitization, yet graphitization is a much more difficult multi-stage procedure than defined by this theory, and its existing crystal dimension The boost of, there are also modifications in atomic valence bonds and modifications in order.
( 3) The concept of crystallite growth. The theory of microcrystalline growth believes that amorphous carbon is composed of microcrystals of eaf thread electrode, which is the basis for the conversion of amorphous carbon into eaf thread electrode framework. At heats, the microcrystals are roughly on the same plane. The crystal layers gradually incorporate with the brand-new carbon mesh airplane as well as increase quickly, as well as at the same time, the layers are turned and also repositioned in the instructions vertical to the layers, thus enhancing the variety of purchased layers. When the microcrystals are generally transformed right into a three-dimensional orderly arrangement, a crystal of 150-600mm eaf graphite electrodes is ultimately formed.
( 4) Issue removal device. Problem elimination device thinks that electrode graphitization is a procedure in which different types of flaws in the amorphous carbon disordered layer framework are slowly gotten rid of under the action of high temperature thermal stress. The removal of layer defects flattens and expands the initial altered layer, creating an ideal carbon hexagonal planar network structure, and also the microcrystalline structure of the electrode graphite slowly establishes. The elimination of layer stacking faults makes the surrounding carbon hexagonal planar mesh layers prepared in an organized fashion, and also the layer spacing slowly lowers, gradually coming close to the crystal framework of eaf thread electrode. The molecular setup of the carbon mesh layer and also the warmth therapy temperature have an important effect on the electrode graphitization process.
[Electrode paste, many people pick CGM carbon] CGM was established in 1992 and has developed into a massive carbon production enterprise with a yearly output of 200,000 tons of electrode paste as well as 250,000 tons of built coke. In the development procedure of CGM Carbon, we have actually experienced several difficulties as well as detours. Nonetheless, with the basic idea of honest management, CGM Carbon has actually grown more powerful. CGM carbon products are not just offered domestically, but likewise exported to Indonesia, foreign nations and various other countries, and are recognized and praised by the global market.
[Electrode paste, why we do it much better] There are 500 electrode paste manufacturers nationwide, and there are greater than 100 manufacturers with a range of more than 10,000 lots. In so many electrode paste production plants, why is CGM carbon in the manufacturing scale? Do better in terms of word of mouth. This starts with the development background of CGM Carbon. CGM Carbon was developed in 1992 and also was initially a carbon venture with petroleum coke calcination as its main company. In 2006, the CGM carbon electrode paste assembly line was taken into operation. The manufacturing of electrode paste requires heat to soften and form the raw materials. The general electrode paste manufacturing facility needs a gas generator in this procedure, as well as in time, it additionally requires extra expensive gas after coal is transformed to gas. Nonetheless, due to the fact that our calcined coke production line can launch a great deal of spare heat, as well as this warmth is simply utilized by the electrode paste production line. Consequently, compared to even more basic electrode paste manufacturers, we have actually currently saved a lot of prices in regards to warmth generation.
[Purchase of electrode paste, please be cautious when running into these issues] The limit for the production of electrode paste in the natural leather bag firm is reasonably high. First of all, ecological concerns. Without an environmental analysis report, it is difficult to create an electrode paste factory; second of all, it is a cost issue., Also if a non-CNC assembly line, the price of an electrode paste handling line is still tens of millions. Not to mention other basic materials and also technical prices. So not every person can afford the electrode paste organization delicately. As a result, there are many trading business on the marketplace that sell electrode paste under the name of the manufacturing facility, yet they have no production capability, let alone customer service. The rate is also frequently very low, as well as when it is sold, it is shoddy. Therefore, when buying electrode paste, you must examine the strength of the factory and also beware of being tricked. Our firm has come across numerous such customers. [Physical as well as chemical indicators of electrode paste] Resistance: Ductility: <5% volatilization: 10.0-15.0 Density: >6-20 Forming: egg tablet, trapezoid, cyndrical tube. Packaging: Heap bag or export packing. According to client requirements. Note: The parameter is the restriction value reached by our factory. Please call us for details.
[Electrode paste, the finest quality raw materials develop the finest quality items] The success of CGM carbon electrode paste is that sophisticated devices and outstanding technology are important variables. Of course, there are other factors that contribute to the improvement of CGM quality. As all of us understand, electric creating coal is the accumulation of electrode paste, and the quality of electrical building coal directly impacts the use effect of electrode paste. CGM carbon electrode paste uses authentic Ningxia Taixi coal, which has low volatility, reduced ash material, high carbon web content, reduced resistance and also high hardness. It is a natural raw material for electrode paste. The carbon web content of Taixi coal is 20% more than that of Shanxi anthracite, as well as the rate is 30% higher. Ningxia Taixi Coal has been called black gold considering that ancient times.
[Electrode paste, CGM carbon can satisfy big orders] This real tale happened in a large alloy group factory in Shandong. Eventually, a supplier pertained to us and claimed that 12,000 tons of electrode paste are required each year. We didn’t think it initially, yet after comprehensive interaction, we learned that he is the proprietor of a tiny electrode paste factory in Shandong since he authorized a contract with a group firm in Shandong for two each year. For a 10,000-ton order, his very own factory has a maximum annual outcome of only 8,000 tons, and the staying 12,000 bunches must be cooperated with the manufacturing facility. With a yearly result of 200,000 lots of electrode paste, CGM Carbon still has a margin of 12,000 bunches. For that reason, not all orders can be eaten by the manufacturing facilities on the marketplace, however CGM carbon is various. CGM carbon electrode paste can satisfy the needs of the team firm’s electrode paste. [Electrode paste, CGM carbon makes the globe without immersed arc furnace accidents] According to data, in all immersed arc furnace mishaps, 20% are electrode paste troubles, and also 30% are triggered by workers. The top quality of our electrode paste can enable consumers to stay clear of these 20% of the problems, and also the after-sales solution of our manufacturing facility designers can supply totally free training to the workers, enabling the manufacturing facility to avoid the staying 30% of the problems.
