Slag Melting Characteristic of Slag Forming and Slag Splashing for BOF Less Slag Smelting

Journal of Iron and Steel Research International, 2012
The slag melting characteristic of slag forming and slag splashing for 300 t BOF less slag process is researched by combining the methods of the slag chemical composition, the melting point determination and the petrographie analysis. The results show that the melting point of final slag for less slag smelting is 20 ’C lower than that for conventional ...

The potential of mining slag as a substrate for microbial growth and the microbiological analysis of slag and slag seepage

Antonie van Leeuwenhoek, 1997
The potential of a Cu/Ni mining slag to act as a substrate for the growth of the bacteria Thiobacillus ferrooxidans, Thiobacillus thiooxidants, and Thiobacillus thioparus was examined. As well, slag and slag seepage samples were screened for the presence of the Thiobacillus species.

The influence of steel slag and ferronickel slag on the properties of alkali-activated slag mortar

Construction and Building Materials, 2019
Abstract With the continuous development of industry, a huge amount of industrial wastes have been produced and caused severe environmental problems. In order to reduce the issue caused by industrial waste, in this investigation, 50 wt% ground granulated blast furnace slag (GGBS) replaced by steel slag (SS) or ferronickel slag (FNS) was used to ...

Effect of Ladle Slag Modification on Slag Sticking to Snorkel and Rate of Slag Erosion

Advanced Materials Research, 2011
To reduce the slag sticking to snorkel and to increase the operation life of snorkel during ladle alloying process, B2O3-CaO (mass ratio 1:2) and CaF2-CaO(mass ratio 1:2) were respectively employed as modifiers added to ladle slag. The effects of modifier on weight of sticking slag and erosion rate were investigated.

Slag-Refractory Interaction in Slagging Coal Gasifiers

Materials Science Forum, 2008
The combustion chamber of slagging coal gasifiers is lined with refractories to protect the steel shell of the gasifier from elevated temperatures and corrosive attack of the coal slag. Refractories composed primarily of Cr2O3 have been found most resistant to slag corrosion, but they continue to fail performance requirements.
