Assessing the impact of oxygen enrichment in smelt reduction vessel is crucial, as improving heat and mass transfer efficiency essential for optimizing production. A three-dimensional mathematical model employing a coupled Lagrangian Eulerian approach has been developed to simulate key processes, including reactions ore powder, devolatilization pulverized coal, post-combustion, other across three zones. The predicted results align closely with actual production data, confirming model's...
The arc characteristics especially the distribution of vacuum remelting (VAR) process are closely related to ingot evolution and consequently final product quality. Taking segregation defects solidification quality as indexes evaluate under different distributions, a three-dimensional full-scale transient model for predicting is developed in this paper. Local time (LST) secondary dendrite arm spacing (SDAS) used characterize This adopted predict channel (freckle) macrosegregation during VAR...
The production of fused magnesia is a process in which raw materials are melted and recrystallized the electric-fused furnace (EFMF). Temperature key factor that affects production, but it difficult to be observed monitored due high internal temperature. Thus, working current standard for workers judge whether normal. In order master heat transfer characteristics accurately control processes, three-dimensional mathematical model coupling magnetic–fluid–thermal multifield has been established...
In this paper, a transient integrated model is proposed to investigate the liquid metal transfer mechanism during consumable electrode melting process of vacuum arc remelting (VAR). The main parameters such as distribution, length and current intensity all have an obvious influence on melting. This first validated then applied simulate under different parameters. numerical results show that droplet only mode throughout tip at diffuse arc, long (50 mm) small (4760 A). mainly drip short with...
