Abstract Phase development during slag formation and reduction of Comilog Assmang ores in a setup that simulates the conditions an industrial SAF process under different coke bed temperatures, 1473 K (1200 °C), 1673 (1400 °C) 1773 K, (1500 was investigated. Graphite crucibles were utilized to contain charge as heating element induction furnace. A temperature profile established, cross-sectional...

Steel products are coated with Aluminum (Al) and Zinc (Zn) alloys to improve their corrosion properties. Bulk steel in batches; however, sheets by a continuous hot-dip galvanizing process. guided into out of the molten Al-Zn-Si (AZ) bath help stainless-steel rolls, known as guiding, sink rolls. These rolls subjected excessive surface AZ and, hence, replaced frequently. The deterioration immerse...

Dissolution of Al2O3-based inclusions are paramount during production special steel and slag engineering is key to enhance this phenomenon. This work evaluates the influence thermodynamic driving force (?C) effective viscosity (?e) on cleanliness three distinct grades composition (Steel/Slag A, Steel/Slag B C). Initial final samples were withdrawal an electric steelmaking facility. The first af...

When considering the extraction of metals from lunar regolith for use in space, one reductive method interest is vacuum thermal dissociation. Given high environment on Moon, sub-liquidus operation such a process, i.e., sublimation, warrants investigation. In current work, kinetics sublimation more volatile major oxides found regolith, Na2O, K2O, and FeO, are evaluated. Two distinct factors acco...

A new technology of hydrogen bottom blowing instead traditional argon in the current converter steelmaking process is proposed herein, aim overcoming problems such as energy shortages caused by increased scrap charging, low stirring intensity blowing, high CO2 emissions, and endpoint carbon content control. The thermal effect metallurgical characteristics were investigated based on production d...

Oxygen-Carrier-Aided Combustion (OCAC) is a promising technology for the combustion of solid heterogeneous fuels such as biomass and waste. However, frequently encountered problem with waste their high alkali contents, which can lead to build-up deposits on heat transfer surfaces, leading corrosion increased maintenance costs. The addition elementary S one options used in processes mitigate cor...

Bereits früher wurde über die Möglichkeit berichtet, heterogene Bauabfälle wie Mauerwerkbruch als Rohstoff für Herstellung von leichten Gesteinskörnungen, den Blähtonen oder auch dem Bims ähnlich sind, einzusetzen. Dieser Weg konsequent weiterverfolgt. Als aktueller Aspekt untersucht, inwieweit gipshaltiger geeignet ist. Damit wird nicht nur (teure) Deponierung dieses Materials umgangen, sonder...

The processing of belite cement clinker in a rotary kiln at about 1000oC is new recycling option for autoclaved aerated concrete (AAC) waste that otherwise must be landfilled. produced can partially substitute ordinary portland (OPC) AAC production. Waste quantities and landfill costs are minimized, while the same time CO2 emissions primary resource consumption production reduced. technology cu...
