FAQ

  1. What is the consumption of your Electrode?

    The comsumption of Our Electrode can be below 1.0kg/mt, and the everage is 0.5kg/mt.

  2. What is the reason of the problem of broken?

    There are several reasons, such as: Amperage is too high, the connection is not good, etc.

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:Which department in the steel plant needs graphite in large quantities?
Steelmaking department. The graphite electrode steelmaking is to enter the electric energy through the graphite electrode to the electric arc furnace, and takes the arc between the electrode end and the furnace charge as the heat source to carry on the steel smelting. The electric arc furnace takes electric energy as heat source, and can adjust the atmosphere in the furnace. It is very beneficial to smelt the steel which contains more easily oxidized elements. Smelting a variety of alloys
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 is the composition of petroleum coke and what is its use?
Mainly used for making carbon products, such as graphite electrodes, anode arc, steel, non-ferrous metals, with aluminum for use; silicon carbide products, such as grinding wheel, rubber, sandpaper; producing goods for the production of synthetic fiber, calcium carbide acetylene and other products; also can be used as fuel for fuel, but for grading impact for grinding superfine grinding, through the JZC-1250 device can be made of coke powder after combustion, using coke powder as fuel is mainly some glass factory, coal water slurry plant etc..
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 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:National standard for graphite electrodes
The national standard normal power graphite electrode graphite electrode: the standard name standard classification number Q51 Standard No. YB/T 4088-2000 for YB/T 4088-2000 YB/T 4088-1992 2000/12/1, instead of the execution time of 0:00:00 release time 2000/7/26 0:00:00 adoption situation
Q:Graphite can be used in acid towers in chemical plants because of graphite
A graphite electrode coated with an antioxidant protective layer (graphite electrode, antioxidant). The utility model has the advantages of forming a protective layer capable of conducting electricity and resisting oxidation at high temperature, reducing electrode consumption (19%~50%) during steelmaking, prolonging the service life of electrodes (22%~60%), and reducing the electric energy consumption of electrodes.
Q:The graphite electrode made by the machining center adopts cooling method, which is water cooled, oil cooled and blow cold. Which is good?
In addition, the infiltration of water on graphite is not good, can not get the effect of dust removal. Now there are special graphite machine, sealing system. Air-cooled can be used, after all, the best air-cooled.
Q:Can Naiduo high temperature graphite
The reinforced graphite gasket is made of flexible graphite tape or flexible graphite and is molded into ring products of different sizes. Suitable for hot water, high temperature, high pressure steam, heat exchange liquid, nitrogen gas, organic solvent, hydrocarbon, low temperature liquid and other medium. Used in compressors, machines, pumps, valves, chemical instruments, instruments, etc..
