Abstract

The invention provides a double-column internal cascading type graphitization production method for an ultrahigh-power graphite electrode. The double-column internal cascading type graphitization production method is characterized by comprising the following steps: feeding a roasted product; charging into a furnace; connecting a bus, and pressurizing and pushing; transmitting power according to apower transmission curve; powering off, keeping pressure and releasing the pressure; cooling; discharging from the furnace; transferring. By adopting the double-column internal cascading type graphitization production method for the ultrahigh-power graphite electrode, targets of high yield, low energy consumption and stable quality are realized; the double-column internal cascading type graphitization production method has the advantages of smooth production organization, simple and feasible operation, stable product quality and high single-furnace capacity.

Description

technical field [0001] The invention relates to the production of roasted graphite electrodes, which is a double-column inner series graphitization production method for ultra-high power graphite electrodes, and is specially used for the production of φ550 / 2410 ultra-high power electrodes in inner series graphitization furnaces. Background technique [0002] At present, due to the different structures, sizes and transformer configurations of the series graphitization furnaces in various domestic carbon plants, there are large differences in furnace loading methods and process parameter control. In addition, when the carbon industry produces large-scale electrode products in series graphitization furnaces, relatively conservative technical means are often used for control. In the previous production process, more emphasis was placed on stable product quality while ignoring the pursuit of single furnace output. However, with the continuous innovation and development of carbon ...
