In the field of materials science, graphite blocks have become key materials for industrial production and technological innovation. It has unique physical and chemical properties such as high melting point, excellent electrical and thermal conductivity, low coefficient of friction and chemical stability. These enable it to adapt to extreme working conditions. From high-temperature furnaces to semiconductor chips, from clean energy to aerospace, graphite blocks<\/a> are widely used.<\/p>\n Furnace Sealing<\/b><\/strong><\/p>\n During the metallurgical production process, the interior of the furnace is often exposed to a high-temperature environment above 1500\u2103and highly corrosive gases. Graphite block\u00a0has\u00a0outstanding high-temperature resistance and chemical stability\u00a0so it is\u00a0the ideal material for furnace sealing. You can\u00a0process\u00a0it\u00a0into sealing gasket or sealing ring, which\u00a0effectively blocks the leakage of high-temperature gases.\u00a0And it\u00a0can\u00a0also\u00a0resists\u00a0the erosion of corrosive gases such as sulfides and oxides inside the furnace. Thus significantly improving the thermal efficiency of the furnace and reducing energy waste.<\/p>\n <\/p>\n Heating Element<\/b><\/strong><\/p>\n Graphite block\u00a0has\u00a0high electrical conductivity and low coefficient of thermal expansion, which\u00a0\u00a0make it\u00a0the core material for metallurgical heating elements. In equipment such as electric arc furnaces and induction furnaces, you can use it\u00a0as heating elements. It can convert electrical energy into high-temperature thermal energy in an instant\u00a0and meet the extreme temperature conditions required for metal smelting. Graphite electrodes can maintain structural stability at temperatures above 2000\u2103.\u00a0Compared with traditional metal heating elements,\u00a0their service life is extended by 3 to 5 times. This significantly reduces\u00a0equipment maintenance costs and downtime.<\/p>\n <\/p>\n Powder Metallurgy<\/b><\/strong><\/p>\n Its self-lubricating property makes graphite block mainly used in mold manufacturing and pressing processes. It\u00a0can significantly reduce the friction during the powder pressing process, which makes\u00a0the powder distribution more uniform. And it avoids\u00a0product defects caused by the adhesion between the mold and the material. Meanwhile, its\u00a0high-temperature resistance of ensures that it\u00a0maintain dimensional accuracy during sintering processes above 1000\u2103.\u00a0So it can be used to facilitate\u00a0the production of high-precision and complex-shaped powder metallurgy components. Such as oil-impregnated bearings for automotive engines and hard alloy cutting tools.<\/p>\n <\/p>\n Mold<\/b><\/strong><\/p>\n Graphite blocks play\u00a0a significant role\u00a0in the fields of injection molds and die-casting molds. Compared with metal molds, its density is only 1\/3 to 1\/5 of that\u00a0metal molds. So it\u00a0significantly reduces\u00a0the weight of the molds and lowers\u00a0the load and energy consumption of the equipment. And its\u00a0high thermal conductivity can increase the cooling rate of the mold by 30% to 50%, which significantly shortens\u00a0the product forming cycle.<\/p>\n <\/p>\n Heating Elements<\/b><\/strong><\/p>\n In the heat treatment process of mechanical processing, you can use graphite\u00a0blocks to process graphite heating elements. Because it can\u00a0precisely control the temperature, graphite heating elements<\/a> can achieve annealing, quenching and other process treatments on metal materials. And it ensures\u00a0that the materials obtain ideal mechanical properties. It can control the\u00a0temperature uniformity error within \u00b12\u2103, far superior to traditional resistance wire heating elements. So it provides\u00a0a stable guarantee for the processing of precision mechanical parts.<\/p>\n <\/p>\n
