Technical characteristics of graphite is mainly determined by its crystalline form. Graphite crystal form different minerals, having different values ??and industrial uses. Industrially, depending on the crystalline form, natural graphite into three categories. Crucible and related products made of graphite forming and refractory crucible and its related products graphite manufacturers, such as crucibles, retorts, plugs and nozzles, etc., with a high fire resistance of graphite, low thermal expansion, melting metal process, by metal infiltration and erosion are also stable at high temperatures good thermal shock resistance and excellent conductivity, so the graphite crucible and its related products are widely used in the process of direct molten metal. Flake graphite manufacturing conventional graphite clay crucible with carbon content greater than usually graphite flake should be greater than mesh (- sieve) Weifang graphite manufacturers, and now the important improvements abroad in the crucible production technology is the graphite type with scales the size and quality has greater flexibility followed by silicon carbide graphite crucible to replace the traditional clay graphite crucible, which is constant with the introduction of the steel industry in technology generated. Constant voltage technology can also be applied to make a small flake graphite graphite wholesale Shandong, clay graphite crucible, graphite and silicon carbide crucible, large flake ingredients only content, carbon content is reduced to graphite. Qingzhou graphite, graphite, carbon industry is provided by the North Sea Dragon Sea Dragon Carbon Co., Ltd. Weifang. Carbon Co., Ltd. Weifang Sea Dragon (www.longmentanye.com) strong, credible, Shandong Weifang graphite and carbon products industry has accumulated a large number of loyal customers.
