The world is changing, and consequently so are policies on the use of natural resources. One most convenient ways to reduce consumption aggregates in production more sustainable construction materials recovered industrial by-products. In this study, concretes designed using siderurgical from electric arc furnaces, taking advantage their high density them as radiation shielding concrete. To veri...

Cokes play an important role in the blast furnace as a spacer for maintaining gas permeability. Since furnaces with large inner volumes exceeding 5000 m3 are now common Japan, use of high strength coke has become crucial issue modern furnaces. However, general methods evaluating strength, example, drum test, insufficient understanding breakage behavior detail. In order to evaluate furnaces, mod...

In view of improved control of the combustion process in e.g. industrial glass furnaces, accurate in-situ COgas sensors are required. With help of reliable in-situ gas sensors, burner control can be optimised. By better burner control, NOx emissions can be reduced and the radiative heat transfer from combustion chamber to the glass melt and thus the energy efficiency of glass furnaces can be im...

Silicon is produced in submerged arc furnaces which are heated by electric currents passing through the furnace. It important to understand distribution of heating within furnace order accurately model silicon production process, yet many existing studies neglect aspects this current flow. In present paper, we formulate a that couples electrical thermal, material flow and chemical processes We ...
