Yetan Shanghai Graphite Co., Ltd.-Ye Carbon Shanghai Graphite Co., Ltd. was established in 2023. It mainly deals in graphite and carbon products and standard fasteners and non-standard fasteners. The company's main products include graphite electrodes, special graphite, recarburizer, carbon bricks, pastes, non-standard graphite products, ferroalloys, alloy cored wires, and various high-quality bolts, nuts, screws, expansion bolts, drill tails and other fasteners and non-standard fasteners.-Graphite Electrode-Graphite electrodes are made of mixed petroleum coke and needle coke as raw materials, coal tar pitch as binder, and are made by extrusion, baking, impregnation, graphitization, and mechanical processing. They are used as conductive materials in EAF (electric arc furnace) and LF (ladle furnace). There are three series: normal power (RP), high power (HP) and ultra-high power (UHP).-Carbon Raiser-Energy storage equipment-YeCarbon Shanghai Graphite Co., Ltd. can provide customers with land transport standard prefabricated cabins, container prefabricated cabins, photovoltaic inverter containers, photovoltaic energy storage power station prefabricated cabins, SVG prefabricated cabins, LNG mobile gas stations, container mobile villas, etc. -Electrode paste-Electrode paste is a conductive material used in electric furnace equipment such as ferroalloy furnaces and calcium carbide furnaces. Electrode paste is also called self-baking electrode. It relies on the heat in the submerged arc furnace to complete the baking. Therefore, the key to the use of electrode paste is to match the electrode consumption rate with the baking rate. Due to the development of submerged arc furnace technology, it is gradually developing in the direction of large-scale and closed. During the baking process, the electrode has reduced the more conductive heat and radiant heat obtained by the open furnace type in the past to only conductive heat. Therefore, the heat obtained by the electrode from the furnace is greatly reduced, which requires improving the sintering performance of the electrode paste to make up for this deficiency.-Fastener-In our daily life and industrial production, there is a class of seemingly inconspicuous small objects that play a vital role - they are fasteners. Various types of fasteners such as bolts, nuts, screws, washers, etc., although small in size, are indispensable connectors in various mechanical equipment, building structures and household items.-Alloy cored wire-Alloy Cored Wire is mainly used as a deoxidizing, decarburizing, and desulfurizing agent in alloy steel and special steel production. It is also used as a reducing agent in high-purity rare earth metal processes.-Graphite Sleeve-Graphite sleeve is an important industrial component used in high temperature and high pressure environments, and is widely used in metallurgy, chemical industry, machinery, electronics, aerospace and other fields. -Isostatic Graphite-lsostatic pressure isotropic graphite is made of high-quality asphalt coke,petroleum coke as raw material and pitch as binder by grinding,batching,mixing,secondary grinding, isostatic pressing molding,baking,impregnation,graphitization,purification and other processes.lt has the characteristics of good isotropic,fine and uniform structure,high mechanical strength,good high temperature resistance, strong chemical corrosion resistance, good electrical and thermal conductivity and excellent machining performance,widely to be used in solar photovoltaic,semiconductor,metal continuous casting,precious metal smelting,and other industries.-Anode side-Graphitiferous cathode carbon block for aluminium electrolysis is made of graphiteparticle as main raw material and pitch as binder by extrusion,baking and machining processes.-Medium coarse graphite-The max grain size of medium &fine-grain special graphite is 2.0mm,1.0mm,0.8mm,0.5mm,etc.,with special production technology,after multiple impregnation and baking, graphitization treatment,it has high strength,good electrical and thermal conductivity and other excellent characteristics.At high temperature state,it has excellent physical and chemical properties,which can be used to produce graphite crucible for high temperature smelting,heating body of vacuum furnace and high frequency electric furnace,graphite vessel for smelting pure metal,mechanical bearing,sealing ring,piston ring and anti-corro- sion equipment of chemical industry.-Graphite Crucible-Graphite crucible is made of artificial graphite electrode material with good thermal conductivity and high temperature resistance. It is used in high temperature processes, has a good thermal expansion coefficient, good resistance to rapid heating and cooling, strong corrosion resistance to acid and alkaline solutions, and can withstand high temperatures of 2000℃. It is used as a high-temperature container for melting and holding non-ferrous metals and producing negative electrode materials.
