Metallurgy and Mechanism of Underwater Wet Cutting Using Oxidizing and Exothermic Flux-Cored Wires [PDF]
Materials, 2021 This paper considers the metallurgical processes of dissociation, ionization, oxidation, deoxidation, and dissolution of oxides during underwater wet cutting. A multiphase mechanism of underwater wet cutting consisting of working and idle cycles of the electrical process in a pulsating vapor gas bubble is proposed. A model of arc penetration into metal

Towards solar metallurgy: Iron ore reduction by ammonia under concentrated light flux
Solar EnergyIron and steel making are responsible for around 7% of global CO2 emissions. The use of fossil fuels to provide both the heat needed to reduce iron ore into iron and the reducing agent is the principal cause of these emissions. Here, we focus on an alternative pathway for direct iron ore reduction using concentrated light power as the heat source and ...

Solar EnergyCurrent ironmaking process leads to large CO 2 emissions due to the use of fossil fuels as both heating agent and reducer. An alternative ironmaking process based on the reduction of iron ore by hydrogen under a concentrated light flux, simulating a direct solar heating reactor, is studied here.
