| Abstract Scope |
This paper analyzes the formation law of liquid phase in the process of ultra-thick bed sintering, and emphatically expounds the key technology and production practice effect of two 500m2 sintering machines of Shougang Jingtang. Through the implementation of ultra-thick bed sintering, Jingtang sintering machine has achieved good results in terms of sintered ore quality, process energy consumption and pollutant discharge. The comprehensive solid fuel consumption of sintering has dropped from 53.95kg/t in the base period to 48.86kg/ t, ignition gas consumption decreased from 2.391 m³/t to 1.553 m³/t; sintering utilization coefficient increased from 1.27t/(m2 h) to a relatively high level of 1.40 t/(m2 h), sintering self-return fines rate decreased, Quality indicators such as drum strength and screening index of sinter remained stable; flue gas volume per ton of ore decreased from 2280Nm3/t to 1779Nm3/t, a decrease of 21.0%; NOx per ton of ore decreased from 0.58kg/t to 0.46kg/t, 20.3% reduction. |
