Product Description:

 

Production Description

Graphite electrode is made from the domestic first petroleum coke and high quality needle coke 

and widely used in the electric arc furnaces for production of alloy steels, metal and other 

nonmetallic materials, etc. The graphite electrodes include regular power, high power, super high power, ultra high power and square electrode. The range of diameters covers from 200mm to 

700mm. Our products own the following characteristics: low electric resistance, good electric and 

thermal conductivity, high oxidation resistance, greater resistance to thermal and mechanical shock, high mechanical strength, high machining accuracy.

Q:Graphite is made of high-strength graphite, it is a kind of graphite grade specification.
Most of the graphite electrodes are cylindrical, but also have square and multi ribbed shapes. Graphite blank refers to the firing of raw materials without processing graphite.
Q:Why graphite can be used as conductive material?
Graphite used in the electrical industry requires a high degree of particle size and grade. Such as alkaline batteries and some special electric carbon products, requiring graphite particle size control within the scope of the project, grade above, harmful impurities are required in the following. The graphite used in a picture tube for television is required below. As a wear-resistant and lubricating material, graphite is often used as a lubricant in the mechanical industry.
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:How does graphite produce solar cells?
Gerrit J said: "despite the modifications, but the inherent nature of graphene remains unchanged, is a significant advantage of composite materials."
Q:How much does a graphite electrode cost about a ton?
According to purity and quality, the price is 1-6 tons / tonDo not calculate the processing cost
Q:How should carbon deposits be treated?
At certain temperature, can make alloy and carbon can react in the engine surface coated with a layer of graphene film, graphene nano particles can fill the pores, wear scratches, on the friction surface repair function.
Q:Why should supercapacitors use graphite as electrode material?
Because graphite material, light weight, good thermal conductivity and conductivity.
Q:What are the skills of hardfacing process for wear-resistant alloy powder blocks?
The hardfacing of wear-resistant alloy powder block is mostly made by carbon arc surfacing. General selection of graphite or carbon arc surfacing carbon rod and plate electrodes, which has good conductivity, high melting point;
Q:What are the factors affecting the service life of graphite electrode in ultra high power arc furnace?
China's graphite electrode quality standard (YB/T4090-2000) to evaluate the quality of the ultra high power graphite electrode is defined 6 physicochemical indexes, including resistivity, flexural strength, elastic modulus, bulk density and linear expansion coefficient as the quality evaluation index, ash as a reference index.
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.
