Mold level fluctuation has always been one of the key factors in slab quality control. Abnormal fluctuations can easily cause slag entrainment and form surface defects hot-rolled cold-rolled steel sheets, thus reducing product qualification rate. In this study, mold data was collected during Ti-bearing Interstitial Free (IF) a stable state for complete casting sequence certain factory. The is analyzed using discrete wavelet transform (DWT) method, its characteristic values are classified...
During casting of titanium stabilised stainless steel, a gradual increase in TiO2 content the molten mould slag from absorption inclusions causes changes properties flux, such as viscosity, solidification temperature and crystallisation behaviour. To simulate this effect fluxes were prepared with SiO2 being substituted 5 10%TiO2 viscosity behaviour studied. Experimental results indicate that substitution leads to suppression cuspidine formation perovskite glass quenched fluxes. The tendency...
Liquidus temperatures of fluoride free mould fluxes simultaneously containing B2O3 and TiO2 have been estimated from two methods, the activation energy for viscous flow DTA technique. Generally, liquidus determined methods are in good agreement. With increase content, variation is consistent. As content increases, slags initially decrease then increase. decrease. Further quenching experiments reveal that there no crystal precipitation slag at temperature DTA, while some can be observed flow....
