| Abstract: |
| The powdery fuel is used to substitute partly for metallurgical coke injected from blast-hole area.Industrial experiments have got good technicaland-economic indexes.The technique that injected mixture of semi-coke and brown coal has been used in industry for one year,technical-and-economic indexes was steady.5 months statistic's indexes show that the furnace capacity has enhanced 10.44%,coke rate and produce cost have reduced 15% and 19.13% respectively,replacement ratio was 1.12,lead recovery ratio was 97.34%. |
