Thermal Conductivities of Slags for Ironmaking and Steelmaking

Utilization of ironmaking and steelmaking slags

smelting of hammerable iron and its treatment in antiquity and Medieval produced also by-product: slag. Because of small yields of iron the process produced only small amounts of slag that did not attract attention of smelters concerning its possible use. the use of slag pieces was only accidental. a lot of slag pieces and blocks from slag pit shaft furnaces were used as a material for mound bu...

Cementitious Properties of Steelmaking Slags

Production and Crystallization Behavior of an Iron Rich Glass–Ceramic Prepared by Ironmaking and Steelmaking Wastes

Using wastes as starting raw materials is a common method to reduce the production costs and the environmental pollution problems arising from such wastes. In this study the production and crystallization behavior of an iron rich glass prepared by iron and steel making wastes has been investigated. The raw materials used, were the blast furnace slag, the blast furnace dust, converter slag and s...

Alternative Methods for in Situ Determination of Iron Oxide in Steelmaking Slags

The most important component of steelmaking slags is the iron oxide since it serves as the oxidizing agent in refining reactions. The measurement of the iron oxide content is performed in the steelworks by taking a sample out of the liquid slag, cooling it and subsequently analysing it. The procedure takes some time. It would be highly desirable, therefore, to develop methods for rapid in situ ...

Thermal conductivities of individual tin dioxide nanobelts

We have measured the thermal conductivities of a 53-nm-thick and a 64-nm-thick tin dioxide (SnO2) nanobelt using a microfabricated device in the temperature range of 80–350 K. The thermal conductivities of the nanobelts were found to be significantly lower than the bulk values, and agree with our calculation results using a full dispersion transmission function approach. Comparison between meas...
