Abstract

The publication presents the functions of the SLAG software created to recreate historical metallurgical processes. SLAG allows for determining the smelting temperature, the viscosity of the metallurgical melt, and the oxygen and sulfur fugacities during smelting. With software, both liquidus temperature and melt viscosity can be calculated using different models, covering the range of chemical compositions of historical slags as wide as possible. Based on thermodynamic calculations, SLAG allows the performance of O₂ and S₂ fugacity calculations in the temperature range of 1000–2000 K (727–1727°C). The range of applicability of other properties (viscosity and liquidus temperature) depends only on the limitations of individual models. Using SLAG, it is also possible to create predominance area diagrams (PADs) and diagrams that consider the viscosity's dependence on temperature for slag of a given chemical composition. Based on glass transition temperature (Tg) and melt fragility, it is also possible to reconstruct the conditions that prevailed during the various stages of historical glass manufacturing processes.

根据炉渣特性重建历史冶炼过程的软件 SLAG

该出版物介绍了 SLAG 软件的功能，该软件是为重现历史冶金过程而创建的。SLAG 可以确定冶炼温度、冶金熔体粘度以及冶炼过程中的氧和硫逸散度。通过软件，可以使用不同的模型计算液相温度和熔体粘度，尽可能广泛地涵盖历史炉渣的化学成分范围。基于热力学计算，SLAG 可以在 1000-2000 K（727-1727°C）的温度范围内进行 O2 和 S2 的逸度计算。其他属性（粘度和液相温度）的适用范围仅取决于个别模型的局限性。使用 SLAG，还可以绘制占优势区域图 (PAD) 和图表，考虑特定化学成分炉渣的粘度与温度的关系。根据玻璃转化温度 (Tg) 和熔体脆性，还可以重建历史上玻璃制造过程各个阶段的条件。

期刊介绍： Archaeometry is an international research journal covering the application of the physical and biological sciences to archaeology, anthropology and art history. Topics covered include dating methods, artifact studies, mathematical methods, remote sensing techniques, conservation science, environmental reconstruction, biological anthropology and archaeological theory. Papers are expected to have a clear archaeological, anthropological or art historical context, be of the highest scientific standards, and to present data of international relevance. The journal is published on behalf of the Research Laboratory for Archaeology and the History of Art, Oxford University, in association with Gesellschaft für Naturwissenschaftliche Archäologie, ARCHAEOMETRIE, the Society for Archaeological Sciences (SAS), and Associazione Italian di Archeometria.
