Q:The reason why graphite is used as electrode

Good chemical stabilityGraphite has good chemical stability at room temperature. It can resist acid, alkali and organic solvent.

Q:How do graphitized electrodes differentiate between high power and low power?

In electrolysis industry, using graphite anode plate as the anode has a history of more than 100 years, the metal anode is in recent decades, the research and application of metal anode in China late last century, only in 70s the technology related to the research and experiment of metal anode, anode on electrolysis industry, mainly through the silver (2%) (0.5%): low silver lead silver alloy, lead and silver tin antimony alloy, lead calcium alloy and lead silver alloy adding nucleating agents and several stages.

Q:Use of graphite in steelmaking

Graphite can be used as an agent for carburizing in the steel making industry. Carburizing uses a wide range of carbonaceous materials, including synthetic graphite, petroleum coke, metallurgical coke, and natural graphite. Worldwide, the use of graphite for carburizing is still one of the main uses of earth like graphite.

Q:Where is the graphite electrode scrap?

Vortex ring formed in a highly ionized internal ICP can be regarded as the secondary coil of the transformer is only one turn, and the work coil water is equivalent to the primary winding of the transformer, the coupling between them, the strength and direction of the magnetic field varies with time, the electronic and ionic field acceleration continuously changes its direction of motion. Lead to Joule heating effect and incidental ionization. This gas forms a new and stable "electric flame" light source in the quartz torch tube in a very short time.

Q:What do carbon products include?

Carbon and graphite materials are mainly carbon based non-metallic solid materials, in which carbon material is basically composed of non graphitic carbon material, and graphite material is basically composed of graphite carbon material. For the sake of simplicity, carbon and graphite materials are sometimes referred to as carbon materials (or carbon materials).

Q:What is the composition of petroleum coke and what is its use?

Petroleum coke can be used for the manufacture of graphite, smelting and chemical industries, depending on its quality. For example, the quality of cooked sweet coke coke, mainly used in the manufacture of ultra high power graphite electrode and some special carbon products; needle coke in steelmaking industry is an important material new technology development of EAF steelmaking.

Q:Please senior doubts. The graphite electrode is used in the mold cavity In what case is graphite processing taken?

Because of the great loss of graphite electrode in finishing, it is not suitable to be used as finishing electrode material. Because of the small coefficient of thermal expansion of graphite, it can also be used as a big electrode material in perforation processing.

Q:What is anodized graphite?

According to the production method of brush, there are two kinds. One is colored brush, that is, metal graphite brush. One is black brush. The black brush is made of petroleum coke, pitch coke, carbon black, charcoal and natural graphite powder and so on. Some binders (such as coal tar pitch, coal tar and artificial resin etc.) are added to the black brush. The resin binder by curing brush manufactured for high resistance brush, and the calcined product called carbon brush and graphite brush (with natural graphite as the main raw material) graphitised after product called electrographite brush,

Q:The graphite electrode made by the machining center adopts cooling method, which is water cooled, oil cooled and blow cold. Which is good?

I had worked on graphite electrodes for 3 years before, and the fact told me that in addition to using the wind to remove the powder, the others were ineffective or disorderly. Because you have to measure size while processing.

Q:How can hydrogen be produced by electrolysis of sodium hydroxide with graphite as an electrode?

Molten sodium hydroxide is ionized out of Na+ and OH-, electrons are lost at the anode OH-, oxygen and water are produced (immediately evaporated at high temperature), and electrons are generated at Na+ at the cathode Na
