Product Description Product DescriptionThe pre-baked anode is made of petroleum coke and pitch coke as aggregates and coal tar pitch as the binder. It is used as the anode material for the pre-baked aluminum electrolytic cell.The pre-baked carbon anode is usually installed in the upper part of the electrolytic cell, and a strong direct current of 60-300ka is passed through the carbon anode and introduced into the electrolyte. The resistivity of the carbon anode is 50-70 μΩ.m, plus the lead and contact resistance, during normal aluminum electrolysis production, the voltage drop on the carbon anode consumed is 300-500mV, which accounts for 10%-15 of the electrolytic cell voltage drop %. A complex electrochemical reaction (anode reaction) that decomposes alumina occurs at the part where the bottom of the carbon anode contacts the molten electrolyte.SpecificationSpecification:SpecificationTypicalUnitValueReal Density2.05g/cm3MinApparent Density1.54-1.6g/cm3-Air Permeability0.5-2npm-Compressive Strength40-55N/mm2-Youngs Moudle3.5-5.5Gpa-Flexural Strength8-14N/mm2-Spe.

For the sake of simplicity, carbon and graphite materials are sometimes referred to as carbon materials (or carbon materials). Carbon products can be divided into graphite electrode, carbon block, graphite anode, carbon electrode, paste, electric carbon, carbon fiber, special graphite, graphite heat exchanger, etc. Graphite electrodes can be divided into ordinary power graphite electrodes, high power electrodes and ultra-high power electrodes according to the allowable current density. The carbon block can be divided into blast furnace carbon block, aluminum carbon block, electric furnace block and so on. Carbon products can be divided into carbon products, graphite products, carbon fibers and graphite fibers according to the processing depth. Carbon products can be divided into graphite products, carbon products, carbon fibers, special graphite products and so on according to different raw materials and production processes. According to the ash content of carbon products, it can be divided into more ash products and less ash products (ash content is less than 1%). Packaging & ShippingTransport and PaymentWe PromiseWe Promise:1.Any inquiries will be replied with in 12 hours.2.Dedication to quatity,supply & service.3.Strictly on selecting raw meterials.4.Reasonable & competitive price ,fast lead time.5.Smple order in stock and one week for bulk production.6.
