A major use is the production of graphite refractory, including the refractory bricks, crucibles, continuous casting powder, mold core, mold, detergents and high temperature materials. In recent years, the refractory industry in two important changes are MgO-C is widely used in steel-making furnace liner and aluminum carbon bricks used in the continuous casting. Graphite refractory steel industry is closely linked with the sale of graphite Lacey, the world steel industry consumes about refractories. Melting in the molten iron is too saturated, with decreasing temperature of the molten iron, carbon is deposited on the surface of the casting graphite morphology, defect ductile iron, compacted graphite iron and other iron-carbon equivalent prone. Often appear in the casting thick at the surface, a lower surface of the sand core or casting solidification last place, such as riser, riser neck edge. It was a dense dark spots (glossy black), a large number of spherical-shaped blossom, dendritic graphite aggregation. This is also a density segregation, macroscopic fracture was continuous and uniform distribution of graphite, color uniform layer of black spots, microscope low magnification (20 to 40 times) was significantly observed gather graphite; 100 times under observation, dense clusters of graphite or connected together. High quality graphite roughness, magnesium, rare earths, sulfur is also high carbon content in the region, hardness, tensile strength, impact toughness decreases. Graphite is an allotrope of elemental carbon, carbon atoms surrounding each link with the other three carbon atoms (the arrangement was more of a hexagonal honeycomb-like) covalently bonded to form a covalent molecule. Since each carbon atom will emit an electron, that electrons can move freely, and therefore belong to the graphite conductor. Graphite is one of the softest mineral, its uses include the manufacture of pencil lead, and a lubricant. Carbon is a nonmetallic element, located at the second cycle Group IVA of the periodic table. Latin for Carbonium, meaning "coal carbon graphite, charcoal," character "C" word by word plus stone charcoal "charcoal" word next to constitute, from the "charcoal" pronunciation. Lacey graphite sale, Sea Dragon Carbon (certified), graphite is provided by Carbon Co., Ltd. Weifang Sea Dragon. Carbon Co., Ltd.
