''•The slag from the ThomasGilchrist process for making steel has long been supposed to have valuable properties as a manure. In the Bessemer converter, there is a lining of lime which, in the process of manufacturing the steel, takes up a large percentage of phosphorus, in the form of phosphoric acid.
Impact of Iron and Steel Slag on Crop Cultivation: A Review The LD slag contains about 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.

Having spent more than 40 years in steelmaking, I think I am qualified to answer this question – but WIKIPEDIA has already done a fine job of answering it. WIKIPEDIA defines steel plant slag as: "Basic slag is a coproduct of steelmaking, and is t...
Converter steelmaking is the main step in orebased steel production using blast furnace hot metal and steel scrap as basic raw materials. About 70% of steel is nowadays produced via different variants of basic oxygen converters. The converter process was developed in the middle of the nineteenth century using bottomblown air for oxidation.
LD steel slag as fertilizer in agriculture. Steel LD slag can also be used in fertilizers for agricultural applications (Das et al., 2007). The efforts have been made in Tata steel that LD slag after grinding to 300 mesh, can be used as a soil conditioner in paddy field, tea gardens etc (Basu et al., 2002).

produced in the Thomas converter process could be made into phosphate fertilizer. "Thomas phosphate fertilizer" manufactured from ground converter steelmaking slag soon became widespread as it proved to be a valuable source of phosphoric acid for plant life. In the 1960s, annual production of Thomas phosphate fertilizer in Ger
iron. For steel making, about 100 to 150 kg/tonnesteel converter slag is discharged, and this byproduct 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/tonnesteel of electric arc furnace slag is generated.
Converting is a type of metallurgical smelting that includes several processes; the most commercially important form is the treatment of molten metal sulfides to produce crude metal and slag, as in the case of copper and nickel converting. A nowuncommon form is batch treatment of pig iron to produce steel by the Bessemer process. The vessel used was called the Bessemer converter.
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.

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, nonexpansive construction material. In the cooling process, some of the lime in the slag may be "hard burnt".
Aug 01, 2015· The role played by the slag in the oxygen converter steelmaking process is very important. Lime is critical to steelmaking. The science of how lime interact with the various components formed during the steelmaking is the basis for understanding the old phrase ''Make the slag and the steel will make itself''.
