Achieving carbon neutrality in the hard-to-abate iron and steel industry requires feasible mitigation at plant level. Presently, decarbonization pathways are mainly assessed country or sector level, whereas specifics regional differences socioeconomic conditions have been underexplored. Here, we take China, world’s largest producer, as an example assess level using a provincial AIM/Enduse model...

Induration furnaces for iron-oxide pellets are expensive processes, due to their high energy consumption. Moreover, they are highly interactive and then complex to control. Real-time optimization strategies based on reliable process models are thus necessary. However, induration furnaces are described by distributed-parameter models that require long computation times. The performance of IMCopt...

Abstract In the present study, a modified duplex melting process was set up so as to be able produce an EN-GJL-150 gray cast iron from local manganese-rich pig iron. A descriptive statistics showed average Mn and Si content in raw material such that: % = 2.457±0.133 0.682±0.088. The demanganization run monitored cascade of two industrial-scale furnaces: rotary kiln electric arc furnace. perform...

The application of direct-current plasma arc furnace technology to the problem coal gasification is investigated using computational multiphysics models inside such units. An integrated modelling workflow for study DC discharges in synthesis gas atmospheres presented. thermodynamic and transport properties are estimated statistical mechanics calculations shown have highly non-linear dependencie...

The present paper emphasizes the potentialities of the industrial use of three-dimensional mathematical modelling of glass melting tanks for optimization of working conditions, design and control of indusaial furnaces. A short review of related recent relevant works is presented and industrial needs and requirements in modelling are discussed. A modelling procedure to solve the heat and mass tr...
