Steel Slag Utilization in Asphalt Mixes
Steel slags are the major byproduct from the conversion of iron to steel in the basic oxygen (major type), electric arc and open hearth (minor type) steelmaking processes. Steel recovery from the slag results in a processed aggregate with both positive (wear resistant, skid resistant, rough textured, angular, well graded, stripping resistant) and negative (heavy, expansive) features. Considerab...
متن کاملControl of Slag and Insoluble Buildup in Ladles, Melting and Pressure Pour Furnaces
Introduction: During the past 30 years, the melting methods and associated molten metal-handling systems used by the U.S. foundry industry have changed significantly. During the same period, while ductile iron production has experienced continued growth, the quality of metallic scrap and other ironunit feed stocks has steadily deteriorated. The result: slag related melting problems have become ...
متن کاملTransient Thermo-fluid Model of Meniscus Behavior and Slag Consumption in Steel Continuous Casting
The behavior of the slag layer between the oscillating mold wall, the slag rim, the slag/liquid steel interface, and the solidifying steel shell, is of immense importance for the surface quality of continuous-cast steel. A computational model of the meniscus region has been developed, that includes transient heat transfer, multi-phase fluid flow, solidification of the slag, and movement of the ...
متن کاملRecovery of Vanadium from Esfahan Steel Company Steel Slag; Optimizing of Roasting and Leaching Parameters
In this Study, vanadium recovery from the steelmaking converter slag was studied. Salt roasting-basic leaching is the process which was applied to separate and extract vanadium from steel making slag. Ground slag was roasted after mixing with determined quantities of sodium carbonate. The effect of time and temperature of roasting and sodium carbonate content were studied. The optimum temperatu...
متن کاملremoval of cadmium from industrial wastewater by steel slag
the steel slag is the main by-product of steel industry. the aim of this study using the steel slag as a low-cost absorbent in order to remove cadmium pollutant from industrial wastewater. some factors that affect the process of cadmium removal by steel slag such as ph, contact time, absorbent dosage and cadmium initial concentration has been studied. standard solution of synthetic wastewater i...
