随着达钢生产规模的不断扩大,氧气供需关系的平衡越来越难,制氧机组启动过程较长、能耗浪费大.在保证公司用氧用氮的前提下,通过变负荷操作进一步降低放散率,灵活的调整生产负荷就成为了不二选择.

According to the sintering production conditions at Dazhou Iron and Steel Group Co. Ltd （DISGC）, the effects of titanium magnetite proportion in ore mix on sintering process and metallurgical properties of sinter are investigated in this paper. The results showed that vertical sintering speed declined to less than 25 mm/min and RDI index became worse with increasing of titanium magnetite concentrate ratio to reach 12 %. For these considerations, titanium magnetite concentrate ratio in ore mix should be controlled within 5 %.

Reaches the steel sintering plant foothold existing iron raw material condition,Uses the crude agglutination cup experimental facility,Has carried on the fumble experiment to the partial hard raw material agglutination performance,Instructs the agglutination production,To improves the agglomerate quality,The improvement agglomerate metallurgy performance played the very important role.

Grasping firmly technic management,optimizing continuously material charge mixture and intensifying technic process controling and the utilization coefficient of 2# 85 m2 sintering machine of DaZhou Steel excess its design capacity consumedly.In 2006 the utilization coefficient achieved 1.711 t/m2·h.The output of sinter ore was continuously improved.

Along with 3# BF of DaZhou Steel putting into production,the production capacity of two sintering machines cannot satisfy the demand of BF production.For improving further the output and quality of sinter,we have earnestly analysed,tested and studied operating principle.We probed constantly for feasible technological operation parameter.Sinter solid burning-out and cost have consumedly been reduced and achieved anticipative effect in the instance of assuring sinter intensity index for one more years.
