| 1 | High-temperature investigation of mould slag crystallization by single and double hot thermocouple techniques显示文摘Methods for the characterization of mould slag crystallization with special emphasis on the single/double hot thermocouple technique(SHTT/DHTT)are reviewed.In the continuous casting process of steels,horizontal heat transfer is mainly influenced by the crystallization behaviour of the mould flux film.Here,both precipitation of crystals out of a liquid phase and devitrification of the glassy film in contact with the mould are of main interest.Therefore,various investigation methods are implemented to characterize different slag properties related to crystallization:a viscometer for determining the break temperature,differential thermal analysis(DTA),confocal scanning laser microscopy,and the water-cooled copper finger test.For near-service conditions,DHTT reveals the most detailed information,including not only the crystallization or devitrification temperature but also the morphology as well as the crystallization velocity.Due to improvements in the device and the representation of the results,a comparison of different samples is possible.Nevertheless,the application field of SHTT/DHTT is restricted to slag systems with low contents of evaporating components.Furthermore,the time required for data analysis is significantly longer than that required for other methods,e.g.DTA.Therefore,the application of DHTT is mainly advisable for mould slag research and development,whereas DTA can also be used for incoming inspections. | Nathalie Kolbl Irmtraud Marschall Harald Harmuth | 2019 | Journal of Iron and Steel Research(International)2019，26，4： | 3 |

| 4 | Identification of secondary raw materials in mold powders and their melting behavior显示文摘Commercial mold powders use a limited number of main mineral constituents,but may differ significantly in chemical composition.The main mineral raw materials of specimens investigated here are quartz,fluorite and free carbon,as well as wollastonite and carbonates.The investigations revealed the use of secondary raw materials like blast furnace slag,fly ash,glass scrap and phosphorous slag as further components.Since the formation of cuspidine was one major point of interest,the influence of the silica source on its formation was identified.A replacement of wollastonite by blast furnace slag reduced the temperature of the first precipitation of cuspidine by about 100℃;the dissociation of sodium carbonate was lowered by-40℃.The lowest temperature of the first Na2CO3 dissociation could be achieved by using fluorine in combination with blast furnace slag.Cuspidine formation from the melt is further decreased if sodium and fluorine are both present.The use of glass scrap and phosphorous slag strongly reduced the temperature of first melt formation and enhanced cuspidine formation. | Irmtraud Marschall Nathalie Kolbl Harald Harmuth Christina Atzenhofer | 2019 | Journal of Iron and Steel Research(International)2019，26，4： | 0 |
