uhp 600 mm graphite electrodes
What are the characteristics of uhp 600 mm graphite electrodes?
How much do you know about uhp 600 mm graphite electrodes? –graphite electrode will give you details.
Graphite is widely used in the electrical industry as graphite electrode, brushes, carbon rods, carbon tubes, positive electrodes of mercury rectifiers, graphite washers, telephone parts, coatings for television picture tubes, and so on. Among them, uhp 600 mm graphite electrodes are the most widely used. When smelting various alloy steels and ferroalloys, graphite electrodes are used. At this time, a strong current is introduced into the melting zone of the electric furnace through the graphite electrode to generate an electric arc, which converts electrical energy into heat energy, and the temperature rises. Up to about 2000 degrees, so as to achieve the purpose of smelting or reaction.
In addition, when electrolyzing metal magnesium, aluminum, and sodium, the anode of the electrolytic cell also uses uhp 600 mm graphite electrodes. The resistance furnace that produces emery also uses graphite electrode as the conductive material of the furnace head. Graphite material is mainly composed of polycrystalline graphite, which is an inorganic non-metallic material, but it is called semi-metal because of its good thermal and electrical conductivity. Graphite has higher thermal and electrical conductivity than some metals, and at the same time It has a much lower thermal expansion coefficient than metals, a high melting point and chemical stability, which makes it of important value in engineering applications. Graphite has good corrosion resistance and does not react with any organic compounds.
Graphite is an allotrope of elemental carbon. The periphery of each carbon atom is connected with three other carbon atoms (multiple hexagons arranged in a honeycomb) covalently bonded to form a covalent molecule. Since each carbon atom emits an electron, those electrons can move freely, so graphite is an electrical conductor. Graphite is one of the softest minerals, and its uses include the manufacture of pencil leads and lubricants. Carbon is a non-metal element, located in the IVA group of the second period of the periodic table.
