Graphite is used in a number of forms in refractories due to its ability to withstand intense temperatures. Alumina-graphite is used to construct nozzles and troughs. Graphite based bricks are used to line steel convertors, blast furnaces and electric arc furnaces. Graphite is used to construct the anodes of all major batteries such as batteries used around the house in remote controls and battery powered toys. Graphite is particularly important in the construction of electric car batteries. Natural graphite and synthetic graphite are both used as a carbon raiser in molten steel. This increases the carbon content in the steel.Graphite is used in the brake linings of large heavy vehicles.Fine flake graphite is used in a certain type of water-based…
Graphite is one of six allotropes of carbon elements,it’s layered crystal structure.As the special crystal structure,graphite shows the unique physical and chemical properties,such like:silver gray,lubricity,electrical conductivity,corrosion resistance,oxidative stability etc.Graphite divided into two categories,natural graphite and synthetic/artificial graphite. The natural graphite come from the graphite mineral,and there are two types of it, Amorphous graphite and crystal graphite(flake graphite).too much impurities in the graphite ore after mining,so it need to be beneficiation before using.the mainly use of natural graphite is produce refractory material,carbon brush,flexible graphite,lubricant,etc.it also be used for carburetant. Among the carbon industry,the largest production of the graphite products is variety of synthetic/artificial graphite.it’s usually manufactured by petroleum coke or pitch coke,and finished after charge mixture, kneading,molding,baking, graphitization and machining,the production…
Graphite electrode is usually used as extruded graphite materials, because of low resistivity of extruded graphite, conductive performance is good, the price is competitive. Mold geometry increasing complexity and diversification of product applications has led to the discharge of sparks getting high accuracy requirements. Graphite electrodes are the advantages of easier machining, electrical discharge machining removal rate is high, small graphite loss, therefore, part of the group of sparks machine customers gave up and switched to the copper electrode graphite electrodes. In addition, some special shape of the electrodes can not be made of copper, but are more easily molded graphite and copper electrodes heavy, not suitable for processing large electrode, these factors have caused some group of sparks machine…
