Abstract At the ratio of iron ore powder of 10%，the influences of coking process conditions (bulk density，heating rate，soaking time) on iron-coke properties (porosity，mechanical strength，thermal property and reduction degree of iron ores) were investigated. The results show that，it is prominent for the coking process conditions to affect iron-coke properties: when bulk density of coal charge is 1.1 t/m3，the properties of iron-coke are excellent; when heating rate is 2.5 ℃/min，the mechanical strength and thermal property are optimal and the iron ore reduction degree increases along with increasing of heating rate; when soaking time ranges between 120-150 min，the properties of iron-coke are the best. Adjustment of the coking process conditions can produce the iron-coke with different properties.

Key words： Iron-coke property Bulk density Heating rate Soaking time
