Compressibility and Foaming behavior of steel slag/waste glass compositesby particle size distribution and foam agents
In present research, the foam glass-ceramic composites fabricated by window glass, steel slag and SiC, CaCO3 foaming agents were investigated by press–sintering method. The optimum sintering temperature was obtained at 1200°C with a 3-minutes holding time and 20°C/min heating rate. The optimum pressure level of 80 MPa for achieving the 70 % of relative density was selected. The effec...
متن کاملINVESTIGATION ON SLAG-REFRACTORY INTERACTION IN LADLE USING COMPUTATIONAL TECHNIQUES
Abstract: Thermodynamic computational packages MTDATA and FactSage have been used to carry out calculations on the variation with temperature of the phases precipitated on cooling in both oxidising and reducing conditions of a typical ladle slag composition, in the temperature range 1700 - 900°C. The current coverage of the databases associated with the computational packages is discussed i...
متن کاملSteel 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 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 کاملEffect of Combining Hydraulic and Phosphate Bonds on Alumina-Spinel Low Cement Castables
A basic alumina-spinel low cement castable (LCC) composed of sintered bauxite, reactive alumina, calcined alumina, calcined magnesia, microsilica, and high alumina refractory cement was prepared (castable A) to which 5% sodium hexa-meta phosphate was later added (castable B) to prepare samples for heat treatment at 110ºC, 900ºC, and 1400ºC. Bulk Density (BD), Apparent Porosity (AP), and Cold Cr...
