Processing and Reusing Technologies for Steelmaking Slag
About 40 million tons of steel slag a year, which is the by-product of iron and steel manufacture, is generated in Japan and the almost all the slag is reused for the materials, e.g. cement raw material, road base course material and civil engineering material, by effectively utilizing its characteristics such as chemical components and mechanical properties. Most of its purposes of uses are to...
متن کاملPossible Uses of Steelmaking Slag in Agriculture: An Overview
Over the past decades, the steel production has increased and, consequently, the higher volumes of by-products and residues generated have driven to the reuse of these materials in an increasingly efficient way. In recent years new technologies have been expanded, and some of them are still under developing, in order to improve the recovery rates of slags. On this subject material separation te...
متن کاملRoles of Mineralogical Phases in Aqueous Carbonation of Steelmaking Slag
Mineralogical phases of steelmaking slags have significant influences on the carbonation of the slags. In this paper, the effects of temperature and reaction time on the conversion of calcium-related phases and the carbonation degree of a slag sample were studied. The experimental conditions were a liquid-to-solid ratio of 20 mL/g, a carbon dioxide flow rate of 1 L/min and a slag particle size ...
متن کاملComputer Simulation of Slag Splashing in a Steelmaking Converter
Some variables that influence the slag splashing phenomenon in an oxygen steelmaking converter are numerically analyzed in this work. The effect of lance height, jet velocity, jet exit angle and slag viscosity on the washing and ejection mechanisms of slag splashing is studied in this work employing twodimensional transient computational fluid dynamics simulations. A parameter here called avera...
متن کاملApplication practice of BOF Slag tailings in steelmaking process
The present paper introduces the steel production and BOF slag processing techniques in Steelmaking Sector of Bayuquan Iron and Steel Subsidiary, Ansteel. The technology of slag tailings utilization has been developed under the consideration of the properties of slag tailing and the characteristics of slag forming in BOF steelmaking operation practice. The processing of the BOF slag includes ho...
