Abstract Scope |
The concept of heating strength of sintering surface is introduced, which is used as the evaluation standard of sintering ignition effect. At the same time, ignition system in Shougang Jingtang sintering machine (550 m2) was studied and analyzed. The results showed that: when the gas flow was stable, duration of high temperature (above 1000 ℃) of the sintering bed surface prolonged with the increase of air-fuel ratio, the highest temperature also rose, which means that the heating intensity of sintering bed increased and the ignition effect improved; By increasing the air-fuel ratio, the coke oven gas consumption decreased by 247 Nm3/h, and the sinter quality index remained stable in Shougang Jingtang Company. |
