②How to guarantee the quality of the products Graphite Electrodes and Nipples？

We have established the international advanced quality management system，every link from raw material to final product we have strict quality test；We resolutely put an end to unqualified products flowing into the market. At the same time, we will provide necessary follow-up service assurance. We have D&B report and you could check details information for our company.

③How long can we receive the product Graphite Electrodes and Nipples after purchase?

In the purchase of product within three working days, We will arrange the factory delivery as soon as possible.

Q:Does the silicon carbide heat plant require a fine structure graphite electrode? What kind of graphite products do you need?: But because the silicon carbide is too hard, it is difficult to machining, good workability, such as non special requirements, using graphite instead of silicon carbide, instead of the effect is not good, but can use a silicon carbide, easy processing, small life than silicon carbide.

Q:Thermal expansion coefficient of graphite: Thermal expansion coefficient (100 degrees Celsius --600 degrees Celsius) diameter 200--500 graphite electrode body is not greater than 2.410 of the negative four times per degree Celsius

Q:What are the losses in graphite electrode?: So tell, this problem is to answer a lot, graphite under high temperature oxidation, generally around 400 degrees, began a slight oxidation, but the human eye is to be observed, with the increase of temperature, the graphite oxide will increase, this time should be used to protect gas or vacuum to protect what you said is, nitrogen protection, and general protection of nitrogen can reach more than 2000 degrees, if the high temperature to 3800 degrees, will you say that vapor formed in graphite surface. To achieve this temperature, it is necessary to add inert gas to achieve, otherwise, can not reach, generally to 4350 degrees, the graphite began to soften.

Q:Is graphite flammable?Why do I bake pencil cores with a fever that doesn't burn?: In theory, as long as a certain temperature is reached, any substance can be burned, and the diamond is converted to graphite at 2000~3000 DEG C under anaerobic conditions. That is to say, graphite (flake graphite)

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:Classification of graphite electrodes: A graphite electrode that allows current densities greater than 25A/ cm 2 is allowed. Mainly used in ultra high power steelmaking arc furnace.

Q:What's the purpose of the electrode material?When the electrolytic molten state of NaCl is said, what is the use of the graphite electrode and the iron electrode?: 1. graphite (two kinds of EDM3 and EDM200)2. copperIn general, graphite electrode for extensive escape material (graphite texture loose, discharge energy is relatively large, removal of materials faster, but face flowers that roughness is relatively large

Q:How to solve the problem of graphite electrode being crushed during electrolysis: I can only use the experience of the past to tell you that if you want to save money easily, the time can be considered as the costA thick graphite stick; inexpensive

Q:What is the striking electrode in the die making? Where is the technical point?: Technology of EDM should master the characteristics of electric discharge between tool electrode and workpiece is not in direct contact, but there is a gap, the gap is generally between 0.05~0.3mm, sometimes may reach 0.5mm or more, full of fluid, processing by high voltage pulsed discharge, the discharge of corrosion the workpiece.

Q:Graphitized coke, graphite, broken, mixed up, how to export?: The graphite powder is soft, black and gray, greasy and polluting paper. Hardness is 1~2, along the vertical direction with the increase of impurities, its hardness can be increased to 3~5. The specific gravity is 1.9 ~ 2.3. Under isolated oxygen conditions, the melting point is above 3000 degrees Celsius and is one of the most refractory minerals. At room temperature, the chemical properties of stone toner are relatively stable, insoluble in water, dilute acid, dilute alkali and organic solvents. The material has high temperature resistance and conductivity, and can be used as refractory materials, conductive materials, wear-resistant and lubricating materials.
