Abstract

The elastic moduli of coke matrices are measured with a nano-indentation method. The effect of coal rank, blending conditions, final coking temperature and holding time at the final coking temperature on the mechanical property are investigated. The elastic moduli of coke matrices are almost the same regardless of coal rank and blending condition. The rise in the final coking temperature increases the elastic moduli. In addition, the rate of the increase in the elastic moduli of inert is smaller than those of active component. With increase in the holding time at final coking temperature, the elastic moduli of active components increase in the temperature range of 650-850°C. However, if the final coking temperature is above about 850°C, the elastic moduli are hardly dependent on the holding time.
