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: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?
The copper electrode used for finishing size of the copper electrode discharge speed is not fast but spent graphite electrode is relatively smallRequirements of the high surface, the appearance of products are copper electrode discharge processingThe iron electrode is not clear enough to be used
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:What do carbon products include?
Carbon products can be divided into graphite electrode, carbon block, graphite anode, carbon electrode, paste, electric carbon, carbon fiber, special graphite, graphite heat exchanger and so on according to the use of products. Graphite electrode class can be divided into ordinary power graphite electrode according to the allowable current density.
Q:What are the losses in graphite electrode?
In EDM, discharge principle is to remove the workpiece material by using the tool and the workpiece anode spark discharge explosion, spark discharge is bidirectional, not only will the workpiece removal part, forming processing, will cause some loss of electrode. Electrode loss is one of the main causes of machining errors in machining, and is an important technical parameter affecting the accuracy and quality of EDM
Q:What is the graphite furnace electrode with a diameter of 400?
With the development of EAF steelmaking technology, the steel-making technology is developing towards large scale and ultra high power. The graphite electrode is mainly made of large size graphite electrode and ultra high power graphite electrode.
Q:What kind of asphalt is better for natural graphite coating?
Main types of graphite electrode with petroleum coke and needle coke, coal tar pitch as binder, calcination, mixing, kneading, pressing, baking and graphitization, and made the processing machine, is a conductor in an electric arc furnace to form arc release electricity for heating and melting of the charge, according to the quality index level, can is divided into ordinary power, high power and ultra high power.
Q:The production of one ton of steel required graphite electrode
Can not generally say, a ton of steel production consumes much of graphite electrode.
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:Graphite can be used in acid towers in chemical plants because of graphite
Ultra high power graphite electrode. A graphite electrode that allows current densities greater than 25A/ cm 2 is allowed. Mainly used in ultra high power steelmaking arc furnace
