Although sometimes graphite powder does not form bright carbon when pouring molten iron, the wetting angle of graphite to molten iron is far greater than 90 °, that is, the sand mold is not wetted by molten iron.
Continue ReadingThe liquid phase method is simple to produce high-purity graphite and has no strict requirements on raw materials. It is suitable for processing raw materials with 10000 mesh to 20 mesh and fixed carbon of more than 80%.
Continue ReadingArtificial graphite is calcined petroleum coke, added with asphalt as binder, and then added with other auxiliary materials. After high-temperature graphitization at 2500-3000 ℃
Continue Readingit has the performance of high-quality natural flake graphite, and has special oxidation resistance under high temperature conditions. Self lubricating and plastic, with good conductivity, heat conduction and adhesion.
Continue ReadingThe raw materials of the two kinds of carburizing agents are different: the graphite carburizing agent is made of 2830 degree graphitized artificial graphite, and the coal carburizing agent is made of anthracite.
Continue Readingit is necessary to know what elements are contained in the carburizing agent so as to better select the appropriate carburizing agent products and make better use of the carburizing agent.
Continue ReadingThe process development of pretreatment agent can be effectively divided into two stages to a certain extent, namely, traditional pretreatment process and modern pretreatment process.
Continue ReadingNatural graphite, as its name implies, is naturally formed graphite in nature. It generally occurs in graphite schist, graphite gneiss, graphite containing schist and metamorphic shale.
Continue ReadingThe main raw materials for producing isostatic pressure graphite are petroleum coke, asphalt coke and coal tar pitch.
Continue ReadingCarburizing agent is an auxiliary material used in steelmaking and casting industries for carburizing and desulfurization. It is most widely used in the iron and steel smelting industry.
