In the traditional iron and steel industry,the application of automation,digitalization and intelligence is an ef-fective means to reduce costs and increase efficiency,and it is also an inevitable trend of the continued development of tra-ditional industries.Through the automatic control of air volume distribution of sintering machine and the expansion and ap-plication of sealing plate of sintering machine,the harmful air leakage of sintering machine is reduced,the air volume dis-tribution of sintering machine is optimized,and the quality of sintered minerals is effectively improved.
