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.
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.
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.
Steel Steel Basic oxygen steelmaking: More than half the world''s steel is produced in the basic oxygen process (BOP), which uses pure oxygen to convert a charge of liquid blastfurnace iron and scrap into steel. The basic oxygen furnace (BOF) is a refractorylined, tiltable converter into which a vertically movable, watercooled lance is inserted to blow oxygen through nozzles at ...

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.

Steel Slag as an Iron Fertilizer for Corn Growth and Soil . steel slag as fertilizer The feasibility of steel slag used as an iron fertilizer was studied in a pot experiment with corn. Slag alone or acidified slag was added to two Fedeficient calcareous soils at different rates. View Details →
The current steelmaking process is based on the Basic Oxygen Steelmaking process, where a basic slag is produced in the LinzDonawitz converter. The LD slag contains about 13 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.

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''.
Steelmaking slag deriving from BOF process (using the LinzDonawitz (LD) converter) comes from the pig iron refining process, wh ich converts molten pig iron and steel scraps into high quality steel. Most slags from steel pl ant derive from this pr ocess, with an average of 150200 kg of slag generated per tonne of st eel produced.
