7. FAQ

We have organized several common questions for our clients，may help you sincerely：

①How about your Warranty of Graphite Electrode ？

Warranty: 1-Year for the whole light. Warranty is based on correct storage, installation, using and maintenanc

②How to guarantee the quality of the products of Graphite Electrode ？

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 after purchase of Graphite Electrode ?

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

Q:Will the brush grease not short-circuit the commutator?: The reverse pole surface should be clean and dry. Any grease, moisture or dust will destroy the carbon film on the commutator surface. The carbon film can not be formed or destroyed. It is very harmful. Grease material will be embedded in the joint between commutator and commutator. Under the action of electric spark, it will be carbonized and conductive. When serious, it will cause partial short circuit between the reversing pieces and reduce the service life of reversing.

Q:The production of one ton of steel required graphite electrode: Not sure, look at your such as what is charge, and your smelting level.If the proportion of molten iron to the furnace is high, then the electrode consumption is low, 0.7kg/t, or lower. If it's cold, 1-2kg/t.

Q:Do electroplating experiments, graphite as an electrode, graphite how to pre process to ensure that the coating will not fall, resulting in increased color of the solution: Use a tight filter cloth as an anode pack

Q:What is the difference between SGL graphite electrode and graphite electrode in general?: Can not say that the more detailed the better, is relative, must be uniform within the range (after all, it is very important to choose the aggregate), such as spectral pure graphite, is not due, he is a lot of technology to producing stains, then burning, and then producing stains, the strength is quite good,

Q:How to improve the efficiency of graphite electrode milling, please tell me: The technical development of the high-speed machining center lays the foundation for improving the milling efficiency and quality of the graphite electrode, especially for the milling of the small electrode with complicated shape and thin wall. In the EDM mold processing, the graphite electrode needs to be processed by the high-speed machining center (HSM), so the demand for HSM machine tools is also increasing. But for some time, because of the technological developments in hard steel processing, it seems possible to make graphite electrodes an obsolete technology.

Q:How to solve the problem of graphite electrode being crushed during electrolysis: There's no way. It's an industrial problem, and that's how graphite works.

Q:What about graphite electrodes for steel mills?: Hebei North graphite electrode factory produces various specifications of graphite electrode, with low resistance, high density, small ash, and so on, so that less tons of steel-making, quality is good

Q:What is the striking electrode in the die making? Where is the technical point?: The electrode in die processing is edm.The discharge produces sparks and forms a "corrosion" to the other pole. The method of machining parts (dies) using this phenomenon is called edm.

Q:Will the concentration of electrolytic sodium sulfite be increased with graphite as electrode?: Can't。 During electrolysis, there is depletion of sulfite ions.

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.
