Estimation of phosphorus distribution ratio at the end of blowing in BOF
Metallurgical and Materials Engineering, 2021 In integrated steel plants, the removal of phosphorous normally takes place during the primary basic oxygen furnace (BOF) steelmaking process. Phosphorous is usually introduced to the integrated steelmaking process through blast furnace additions, such as iron ore, coke, sinter, and fluxes.

Film Cooling from a Single Row of Compound AngleHoles at High Blowing Ratios [PDF]
International Journal of Rotating Machinery, 1996 Experimental results are presented which describe the development and structure of flow downstream of a single row of holes with compound angle orientations producing film cooling at high blowing ratios. This film cooling configuration is important because similar arrangements are frequently employed on the first stage of rotating blades of operating ...
