In order to solve the problem of the impact of the blower's surge phenomenon on the equipment itself,and even the occurrence of explosions and fires and other accidents,on the basis of a brief overview of the blast furnace steelmaking process and the blower,an in-depth analysis is carried out on the judgement mechanism of the surge phenomenon of the blower,the factors affecting it and the principle of the control of the anti-surge,and it is concluded that,based on the ratio of the real-time working condition point of the blower to the energy head of the surge point,the blower can be used as a basis for judging whether there is the phenomenon of surge or not.Finally,based on the ratio of real-time working condition of the blower and the energy head of the surge point,it is concluded that it is the basis for judging whether there is a surge phenomenon or not,and determining the relationship between the openings of the air release valve corresponding to different ratios,which lays the foundation for guiding the anti-surge control of the blower in practice.
