چکیده
The technology of submerged carbon powder injection with CO2 and O2 mixed gas (SCPI-COMG) is a new type technology. It can increase the molten bath content improve steel quality by injecting directly into gas. To optimize process parameters this novel technology, mechanism effect SCPI-COMG on EAF steelmaking were investigated in study. Based an induction furnace experiment, effects carburization fluid flow scrap melting analyzed. A mathematical model axis jets liquid was built to analyze impact behaviors steel. results theoretical model, for jet steel, α ≥ 20°, horizontal inject distance decreases increasing 0° ≤ increases increasing. Finally, based newly materials energy balance SCPI-COMG, influences gas-solid technical indexes also analyzed.is very useful optimizing SCPI-COMG. study are Gas Jet Liquid Steel.

Pragmatic analysis of the electric submerged arc furnace continuum
A transient mathematical model was developed for the description of fluid flow, heat transfer and electromagnetic phenomena involved in the production of ferronickel in electric arc furnaces. The key operating variables considered were the thermal and electrical conductivity of the slag and the shape, immersion depth and applied electric potential of the electrodes. It was established that the ...
متن کاملChar refiring under O2/N2 and O2/CO2 atmospheres. Implication for PCI injection in blast furnace
It is attempt in pulverized coal injection (PCI) in blast furnace tuyeres to increase the injection rate without increasing the amount of unburned char inside the stack of the blast furnace. The unburned char can cause problems in the blast furnace operation, such as reduced permeability, undesirable gas/temperature distribution, excessive coke erosion and significant char carryover. In the nea...

متن کاملRecycling Evaluation of Mill Scale in Electric Arc Furnace
A considerable amount of mill scale is generated from steelmaking plants annually. Although some industries use it as raw material however, since it contains iron in the form of FeO, Fe2O3, and Fe3O4, it can be considered as a valuable metallurgical raw material for iron and steelmaking industry as well. Thus, the aim of this study was to evaluate the possibility, efficiency, and consequences o...
متن کاملA KINETIC STUDY ON THE CARBOTHERMIC REDUCTION OF ZINC OXIDE FROM ELECTRIC ARC FURNACE DUST
In the present study, reduction of zinc oxide from the pellets made of steelmaking electric arc furnace dust has been investigated. Effects of such parameters as the type of carbon material (graphite, coke and charcoal) as well as time and temperature on the reduction reaction have been examined. The reduced (dimensionless) time method was applied to perform a kinetic analysis of the system. Ex...
