查询词典 molten metal

Experience shows that the introduced magnetic field can give an effective intervention to the transition of droplet, flowing of molten bath metal, crystalline and nucleation of molten bath and the process of crystalline growth. The magnetic field promotes the refining degree of primary crystallization structure , decreases the chemistry non-homogeneity, So it can strengthen hardness and wearing resistance of weld metal overlay and improve quality of surfacing deposit.

实践表明，利用外加磁场对焊接中熔滴的过渡、熔池金属的流动、熔池的结晶形核及结晶生长等过程有显著作用，使堆焊层的一次结晶组织细化，控制硬质相的分布，减小化学不均匀性，从而提高了堆焊层金属的硬度和耐磨性，全面改善堆焊层的性能。

The results reveal that spectra obtained by different parametric methods are similar. The spectra of normal cells' voltage have only one noticeable lobe due to fluctuation of molten alumina at anodes, while spectra of other abnormal cells have one mainlobe and one sidelobe. In cells with carbon in bath the spectral mainlobe of cell voltage is still due to the fluctuation of molten alumina at anodes and the sidelobe is due to the fluctuation of carbon in bath; in cells with metal pad wave, the spectral mainlobe is due to metal pad waving and the sidelobe is still due to the fluctuation of molten alumina at anodes. Compared with wavelet packet analysis, spectral analysis is simpler and takes less time in calculation, which is a big merit in the large-scale application of online diagnosis systems of working conditions in aluminum reduction cells.

研究结果表明：不同的参数估计法得到趋于一致的频谱分析结果，正常槽只有1个尖锐谱峰，对应于阳极下熔融氧化铝涌动的特征峰，其他故障槽都有2个特征谱峰，即1个主峰和1个次峰，碳渣槽的主峰仍然对应着阳极下熔融氧化铝涌动特征峰，次峰对应悬浮碳渣的涌动特征峰；铝液波动槽主峰对应铝液波动特征峰，次峰对应着熔融氧化铝涌动的特征峰；频谱分析相对于小波包分析具有算法简单、耗时少、物理意义明确等特点，在槽况在线诊断系统的大规模推广中具有优势。
