- In order to minimize cost and protect environment, the BOF slag as dephosphorizing agent has been utilized.
- Hot metal dephosphorizing factors are analyzed and practice on dephosphorizing powder for hot metal pretreatment with LT-dust and BOF slag is introduced.
- The 30 t BOF at Shanghai No. 1 Iron &Steel Corporation uses usually poor quality hot metal for steelmaking.The FeO content in BOF slag is very high at the end point of smelting.
- The distensibility of BOF slag was measured by steam test method and the effect of size and ageing time on the distensibility was investigated.These gives evidence for application of BOF slag.
- According to the experimental results, the utilization of oyster shells, rice husk ash, WTPS and BOF slag as cement raw materials to produce Alite-rich cement and Belite-cement is feasible.
- Pinchen, 36 and 26 tons BOF slag and De-S slag per hectare;
