Ferrochrome slag utilization in concrete and mortar as an aggregate replacement. Aggregate replacement is one of the main promising areas for FCS utilization since 60–75% of the concrete volume is occupied by aggregate [7]. Different research studies explored the utilization of FCS in concrete production as partial and full …
In a nutshell, this study provides a thorough and critical examination of ferrochrome slag and ferrochrome ash's suitability for construction, as well as a list of …
This processing plant is for the slag to recovery the Ferrochrome. The process is as below: The wheel loader or excavator feeds the raw slag to the hopper. There is an Electromagnetic vibration feeder under the hopper, which can feed the material to the belt conveyor more evenly.
Glass-ceramics have been successfully prepared from high-carbon ferrochromium slag (HCFS) and waste glass (WG), and the microstructural characterization and mechanical properties of the glass-ceramics were subsequently investigated. The development of HCFS-based glass-ceramics involves the nucleation …
