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 is the reason that the current cannot be increased when the graphite electrode is used for anode electrolysis?Add calcium chloride and sodium bicarbonate into electrolytic water
Because in the process of electrolysis of water in cathode electron generated hydroxyl, the alkaline solution increased. But with the hydroxyl reaction of sodium carbonate and sodium bicarbonate, carbonate and calcium ions exist at the same time, must produce the precipitation of calcium carbonate, the ion in the solution is reduced, thereby conductive resistance increases. Thus weakened over time current cannot be raised
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:Carbon graphite electrode and what is the difference?
Graphite electrode is a mixture of natural graphite and petroleum coke and asphalt coke. After being treated by high temperature graphitization, the material is composed of graphite;
Q:Why is the production of one ton of ultra high power graphite electrode requires 1.05 tons of coke?
Petroleum coke is divided into needle coke and sponge coke and projectile reef, fixed carbon content components of petroleum coke is around 80%
Q:Please senior doubts. The graphite electrode is used in the mold cavity In what case is graphite processing taken?
Graphite electrode has better machining stability and high production efficiency. It is easy to be used as EDM electrode material in EDM when it is processed with long pulse width and high current.
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:The use of graphite as an electrode in alumina electrolysis
The technical knowledge of electrolytic aluminum, cleaning and maintenance of alumina equipment, you can search for Baidu on the green, looking for.
Q:Graphite is made of high-strength graphite, it is a kind of graphite grade specification.
The difference is: the graphite bar may be machined graphite electrode materials may be insulated with material of graphite. Graphite electrode is an electrode product to guide the processing of graphite material with good electrical properties. Bars are usually cylindrical.
Q:Is the anode of electrolytic water suitable for ordinary titanium wires?
The graphite is cheaper and easier to obtain, but the carbon electrodes sold in the general market are not very pure at most times. The experiment is done for a period of time, and the carbon is inexplicably broken, especially if you need to work for a long time. So, if your graphite electrode is of good quality, it's still graphite.
