The influences of heating pattern and sodium carbonate addition on the carbothermic reduction ilmenite concentrate have been experimentally studied. experiments were carried out using isothermal–gradient temperature technique between 1000 °C 1500 with different profiles for a total time 110 160 min. was varied 0 to 60 wt%. It found that profile play an important role separation metallic iron gr...

The use of steel-making slag as catalysts for microwave-assisted dry reforming of CH4 was studied. Carbon materials (an activated carbon and a metallurgical coke), mixtures of carbon materials + Fe-rich slag and mixtures of carbon materials + Ni/Al2O3 were tested as catalysts. Mixtures of slag with carbons gave rise to higher and steadier conversions than those achieved over carbon materials. T...

The present investigation revealed the effect of using silica fume and copper slag as a partial replacement of cement and fine aggregate, respectively on the mechanical properties of the concrete. Due to the depletion of natural sand resource worldwide with the increment of industrial waste, simultaneously, partial replacements of fine aggregate with copper slag have been attempted. Therefore, ...

Slagging-off (i.e., slag removal) is an important preprocessing operation of steel-making to improve the purity iron. Current manual-operated removal schemes are inefficient and labor-intensive. Automatic slagging-off desirable but challenging as reliable recognition iron difficult. This work focuses on realizing efficient accurate algorithm slag, which conducive realize automatic operation. Mo...

Abstract Aluminum and iron hydroxides, formed in the stone during hydration of cement with addition special slags, significantly improve properties concrete. The low-basic calcium aluminates CA 2 6 form high-alumina slag, which releases a large amount Al(OH) 3 hydration, increases strength, density, water resistance, frost corrosion resistance hydraulic A compressed mixture concrete scrap slag ...

Pada beberapa tahun terakhir, pertumbuhan industri pengolahan material non fero seperti nikel, alumumium maupun tembaga berkembang sangat pesat. Hal ini secara tidak langsung berdampak terhadap peningkatan limbah metalurgi hasil tersebut. Di Indonesia, slag logam diantarannya Nikel Pic Iron (NPI) merupakan salah satu yang belum digunakan optimal. Disisi lain NPI diketahui mengandung unsur-unsur...
