Abstract:
Based on lots of investigation and analysis for internal and overseas
slag detection system (SDS) technology, a kind of SDS realization method
using wavelet analysis is brought forward. According to the
characteristic of design and realization for SDS, experiments platform
for vibration measurement is established. After studying casting process
from ladle to pouring box and protection casting supporting mechanical
structure, vibration dynamics model of supporting structure is founded, also variation of steel water impact force and influencing factors of
inspecting spot vibration are discussed. Primary analysis is done for
steel water vibration signal by the way of basal wavelet processing
method, and the deeply feature extraction is finished to realize the
effective recognition for steel water status using wavelet package
method. Experimental results indicate that the method has low
realization cost and long operating life, requires little rebuilding for
current devices, and its slag detection rate can reaches more than 95
percents.
Key words: Slag detection Continuous casting
