Predicting slag viscosities in metallurgical systems
JOM, 2002Slag viscosity is a major process variable for most pyrometallurgical smelting and refining process operations. While extensive measurements have been made of slag viscosities, it is not practicable to provide data on all the possible combinations of compositions and process conditions encountered in metallurgical practice.

Effects of slag characteristics on sulfate durability of Portland cement-slag blended systems
Construction and Building Materials, 2019Abstract Sulfate resistance of Portland cement-slag mixtures was compared at 30, 50 and 70% cement replacement levels for slags with variable Al2O3 and MgO content and variable fineness in combination with moderate- and high-C3A cements. Sulfate resistance generally decreased with increasing slag Al2O3 content, although decreasing MgO also increased ...

The reduction experiment of iron ore containing high Alumina content with petroleum coke was carried out in the temperature range of 1673 to 1773K by changing the slag composition. The sulfur and phosphorous content in the reduced iron nugget were measured to investigate the desulfurization and dephosphorization behavior during the reduction.

Experiments were conducted to examine of nitrobenzene reduction by steel convert slag (SCS) with Fe(II) system. The results showed SCS with Fe(II) was an effective reductant for nitrobenzene at pH 5.5-6.5. Further analysis suggested Fe(II) was adsorbed by SCS through ion replacement with SCS-bound Ca(II).

The effect of blast furnace slag chemistry on carbonation characteristics of cement-slag systems
2022In order to compensate the limited availability of raw material resources and meet the growing demand for decreasing CO2 emissions during cement and concrete productions, a practical method is to decrease the clinker content in cement. This strategy mainly consists of substituting a part of the clinker with supplementary cementitious materials (SCMs ...

Slag Monitoring System for Combustion Chambers of Steam Boilers
Heat Transfer Engineering, 2009The computer-based boiler performance system presented in this article has been developed to provide a direct and quantitative assessment of furnace and convective surface cleanliness. Temperature, pressure, and flow measurements and gas analysis data are used to perform heat transfer analysis in the boiler furnace and evaporator.

Cement and Concrete Composites, 2016
Abstract This study collected four ground granulated blast furnace slags from different manufacturing locations for CaO-activation to investigate the influence of the slag characteristics on strength development and the reaction products. Despite the seemingly similar characteristics of the slags, each slag developed significantly different strengths

Electrocapillary Phenomena in an Iron-Slag System
1965In most metallurgical processes, interaction between the liquid metal and molten slag plays an important part. The further improvement of metallurgical production calls for increased research on the properties of slags. The greater attention which has recently been paid to the electrochemical properties of slags should be noted.

The Rheological Properties of Heterogeneous Slag Systems
Slags are molten oxides formed during the high temperature smelting processes used to produce metals. These complex liquid oxide phases play a key role in removing unwanted elements from the several hundred million tonnes of metal produced annually. Understanding and controlling the flow behaviour of the slag phase is crucial to improving the technicalopenaire +2 more sources
