Abstract：By using minute particles of SiO2 as dust, simulation research on the EAF dust collection characteristics by cold model coke bed filter was carried out: For fixed bed filter, it was found that the longitudinal distribution of static hold up at steady state can be regarded as constant for a certain gas flow rate condition. For moving bed filter, the total static hold up increased with dust supply rate and presented an increased pattern from top to bottom. Under the experimental conditions, after comprehensive considerations of quantity, rate and efficiency for static hold up, the rate of gas supply should not over 0.65 m/s.
