J. Cent. South Univ. (2017) 24: 1736-1744 DOI: https://doi.org/10.1007/s11771-017-3581-y Inhibition mechanism between sodium (Na3AlF6) and sulfur on coke reactivity ZHONG Qi-fan(仲奇凡)1, XIAO Jin(肖劲)1... (Na3AlF6) and sulfur on coke reactivity was investigated by simulating petroleum coke with low-impurity pitch coke and by impurity doping. The mechanism was discussed by scanning electron microscopy......
dispersive spectroscopy (SEM-WDS). The results show that adding 0.075% (mass fraction) Co into the Zn bath can completely inhibit the silicon reactivity in the galvanized coating on the Q235 steel. But for the Q345 steel, to inhibit the silicon reactivity, 0.3% Co should be added into the Zn bath. The loose ζ layer is transformed into the Co-rich ζ layer contacted directly with the liquid phase......
