Abstract
Tangshan Steel New District adopts new technology and technology for 500 m2 sintering machine from five as-pects,such as fuel system,batching system,mixing system,sintering cooling system and finished product system.Among them,fuel pre-screening technology can effectively reduce the problem of secondary combustion in the electric field of the sintering machine head,improve the use efficiency of roll and four rolls,and improve the equipment life.The new mobile unloading car material splitting technology reduces the failure rate of the unloading car and saves the equipment mainte-nance cost.The steam injection technology of sinter surface and the zero emission technology of flue gas of ring cooler play a key role in energy saving,emission reduction,production increase and efficiency increase.The design level and equip-ment level of the sintering machine are in a leading position in iron and steel enterprises,and it has a certain guiding role for the process design of large-scale sintering machines.
