Electrode paste material calcined petroleum coke
Calcined petroleum coke is an excellent material for producing electrode paste
This paper introduces one of the raw materials of electrode paste, petroleum coke, and analyzes its characteristics and quality index.
Calcined Petroleum Coke
Petroleum coke is the product of carbonization of petroleum refining residue after high temperature treatment. It is characterized by low ash impurity content, high temperature liquid phase arrangement and easy graphitization. It is one of the by-products of petroleum refining process.
Came out from the oil refinery of petroleum coke is commonly raw coke, it contains about 10% - 14% of the volatile, petroleum coke need after 1350 ℃ high temperature calcination to remove volatile can be used as a carbon material, quality of petroleum coke calcined by determination of the calcined petroleum coke true density, resistivity, ash content, volatile matter and moisture index to evaluate, the level of the quality indicators are mainly depends on the duration of the calcination temperature and high temperature.
The higher the temperature and the longer the duration, the lower the corresponding resistivity and the greater the true density.
Calcined petroleum coke has the characteristics of small expansion coefficient, good thermal stability and easy graphitization at high temperature.
The main quality indicators are shown in table 3-1.

Generally, when the cathode carbon block is lower than its roasting temperature, it shows a positive coefficient of thermal expansion as the temperature increases, while the ramming paste will shrink from curing temperature to the maximum roasting temper
From 1954 to 1976, calcined petroleum was widely used in aluminum plants. On the one hand, the carbon plant of aluminum factory produces anode paste, using local materials; On the other hand, there were no more effective pastes.
An important index to measure the performance of calcined pet coke is the content of volatiles in calcined pet coke. If the content of volatiles in calcined pet coke is too high, the shrinkage ratio of raw anode will be large in the roasting process, and
