The current steelmaking process is based on the Basic Oxygen Steelmaking process, where a basic slag is produced in the Linz-Donawitz converter. The LD slag contains about 1-3 wt% of P2O5, which is too low to be used as phosphate fertilizer, but, at the same time, it is too high to be used in the BF or recycled in the sinter plants.
Steel works slag is a by-product of the basic oxygen steel making process used by orus at their Port Talbot, Scunthorpe and Teeside works. Like the old basic slag our grade of steel works slag called Super Slag Basic is principally a lime based material which has absorbed the . oxides and trace elements arising from the refining of iron.

Managing the process. When the required steel had been formed, it was poured into ladles and then transferred into moulds while the lighter slag was left behind. The conversion process, called the "blow", was completed in approximately 20 minutes.
Not all steel slag is expansive, but water quenching is the first step in weathering of steel slag which may be essential to provide a stable, non-expansive construction material. In the cooling process, some of the lime in the slag may be "hard burnt".
It is clear that the leaching process of steel slag will not cause soil damage, but the application of steel slag in Chinese agriculture is still forbidden. (2) In addition, China does not have a standard for steel slag fertilizer and soil modification, which affects the development of slag fertilizer technology.
iron. For steel making, about 100 to 150 kg/tonnesteel converter slag is discharged, - and this by-product contains not only the converter slag but also the slag generated during hot metal pretreatment. When scrap is used as the main raw material for steelmaking, about 120 kg/tonne-steel of electric arc furnace slag is generated.
