摘要： In a method for desulfurizing hot metal by analyzing S concentration of a sample taken out from the hot metal, the S concentration is analyzed rapidly and precisely by a method comprising a high frequency induction heating step of oxidizing the sample under a high frequency induction heating in a pure oxygen atmosphere to convert S in the hot metal to SO2 and an analysis step of analyzing SO2-containing gas generated in the high frequency induction heating step through an ultraviolet fluorescence method to quantify S concentration in the sample, whereby S concentration after the desulfurization is controlled precisely and hence fault of S concentration is prevented but also the increase of the cost due to the excessive addition of a desulfurization agent and step disruption at steel-making step are prevented.

摘要： An alloyed hot-dip galvanized steel sheet is obtained by forming a hot-dip galvanized layer on the surface of the steel sheet and then alloying the steel sheet. The steel sheet exhibits a potential of −850 mV or less when it is immersed in a zinc sulfate-sodium chloride electrolyte. Alternatively, when it is electrolyzed according to constant potential electrolysis process in a zinc sulfate-sodium chloride electrolyte at a potential in a range from −940 mV to −920 mV, the quantity of electricity consumed is less than or equal to 0.5 C/cm2. The steel sheet exhibits excellent processability and particularly excellent sliding property.
