Analysis of modality and starting-braking process of rectlinear vibrating tap-hole driller in BF

On the basis of the vibration theory the modality and the starting-braking process of rectlinear vibrating tap-hole driller in BF (blast furance) are analized.On the designing stage,through the analysis of dynamics characteristics,some parameters can be reformed, and the rectlinear vibrating tap-hole driller can work on the best working state. On this condition, the productivity and production power of this kind of vibrating tap-hole driller can be raised, at the same time,the dynamicial pressure can be reduced to the minimum, and the intensity and service life of the rectlinear vibrating tap-hole driller can also be raised.Through the analysis of the dynamics characteristics of the rectlinear vibrating tap-hole driller on line,the best designing scheme can be gained.The computing program has been programed on the basis of the vibrating theoritical analyses and the measured data,and the good foundation of improving the design of the rectlinear vibrating tap-hole driller has also obtained.
