摘要：

Effective thermal conductivity of metallurgical coke was measured in the temperature range from 1 00 to 1 400-degrees-C by using the laser flash method. Effective thermal conductivity k of coke increased with a rise of temperature, and decreased with an increase of porosity of coke. The effect of radiation in the pore of coke on the value of effective thermal conductivity of coke was very small. The following empirical equation was obtained for the determination of effective thermal conductivity k (W/m K) as a function of temperature T(K) and porosity epsilon (-) of coke. k= {0.973+6.34 x 10(-3)(T-273)}(1-epsilon, 2/3)
