Abstract

A three dimensional mathematical simulation model has been developed to study on the scale up of a new ironmaking process (SC process) which consists of a shaft type reduction furnace and a cupola type melting furnace. Results obtained are as follows;
1) The fuel rate of a 2 400 t/d plant with the productivity of 5 t/dm3 is estimated to be 525 kg/t.
2) In this case, gas and solid flows tend to deviate from the uniform flow, which gives effects on the operational performance. Especially, discharging holes must be located at the appropriate positions of the reduction furnace to increase the gas utilization degree.
