In the present work, effect of basicity at lower range from 0.98 to 2.13 on dephosphorization hot metal 1623 K was studied through high-temperature laboratorial experiments. With increase 2.13, P and C contents in rapidly decrease first, then gradually increase, respectively. From scanning electron microscopy-energy dispersive X-ray spectroscopy (SEM-EDS) diffraction (XRD) results, with basicit...

During the converter steelmaking process, gas-slag-metal three-phase emulsification is realized by injecting gas to complete metallurgical tasks such as slagging, dephosphorization, decarburization, and heating. As green intelligent development of steel industry progresses, injection technology also constantly innovating. In this review, types applications top blowing elements, bottom medium ar...

In the BOF steelmaking process, lime quality and quantity directly affect slag quality, affecting metallurgical results, liquid metal yield, productivity, therefore total cost environmental impact of steel production. this paper, a value in use model based on mass balance heat was developed used to evaluate process. The has been successfully validated using data Steel Plant. Then three types wi...

This study analyzes the pore structure and durability of concrete according to four different ratios steelmaking slag powder (SSP). Concrete containing SSP increased formation gel capillary pores due delayed hydration, largest cumulative volume was observed when incorporation ratio 20%. In terms durability, had decreased performance compared without (NN), which changes in caused by incorporatin...

The mechanism of feeding slag-forming mixture (SFM) with a pneumatic drive has number disadvantages associated, in particular, the uneven supply into mould. To eliminate drawbacks, device an electric was designed to them. In order ensure control SFM process, automated system been developed that provides real-time information on technological process mould continuous casting machine, including s...

Copper smelter slag and copper smelter slag flotation tailings were leached using sulphuric acid solutions, without or with the addition of either ferric sulphate or hydrogen peroxide. Copper extraction from the slag was typically found to be twice as high as that from the slag flotation tailings. Hydrogen peroxide was determined to be the best lixiviant. Thus, copper and iron extractions were ...
