In order to change the current use of imported needle coke and medium temperature asphalt as raw materials to produce ultra-high power (u1trahigh power
Known as UHP) graphite electrode, this paper uses domestic oil-based Jinzhou needle coke and Tianjin modified asphalt as raw materials
UHP graphite electrode was prepared by adding Fe indica and oleic acid (or stearic acid). Through comparative experiments, explore the domestic Jinshao I'I needle
There are differences in quality between shaped coke and imported needle coke, medium temperature asphalt and modified asphalt, as well as the corresponding products
Zhou needle coke and Tianfeng modified asphalt were used as raw materials, and 1% Fe: 0 was added. After testing its impact on the product quality
On the basis of this, different contents of oleic acid and 0.5% stearic acid were added to investigate their effects on the product quality. Through the Institute
The indicators of the samples were tested and the microstructure was analyzed, and the samples were produced with imported needle coke and medium temperature asphalt as raw materials
Through comparison, determine the process parameters to obtain the best performance, and finally determine whether UHP graphite electrode can be produced by this method,
Realize the localization of ultra-high power graphite electrode. The paper also added different amounts of Tianjin modified asphalt at 433K
Determine the appropriate amount of oleic acid and verify whether it is consistent with the above experimental results
To. The experimental results show that this method can produce ultra-high power graphite electrode.
