Power electronic converters (PEC) are integral to various sectors, including power systems, transportation, and industrial production, where their reliability significantly influences overall system performance. Despite its importance, current research has not thoroughly addressed the simultaneous impact of component performance degradation functional failures on This paper introduces a prediction method for PEC that considers both failure. Initially, digital prototype models developed...
Gas‐based shaft furnaces (SFs) have garnered considerable attention because of their low CO 2 emissions. The sticking behavior burden material influences the smooth operation SFs. In this study, effects reduction degree, temperature, and atmosphere on pellets are studied thoroughly under typical conditions. results demonstrate that will stick with each other as degree increases, main phase at maximum index (SI) is iron, interconnection between iron whiskers in bonding phenomenon pellets....
The oxidation process of iron ore with different Cr 2 O 3 contents is separated into two stages. Coats–Redfern method applied to conduct the kinetic analysis, and restriction links between stages I II correspond diffusion control. apparent activation energy ( E ) progressively decreases at all as increase, which favorable for improving kinetics. fluctuation amplitudes in are 5.450 16.021 kJ mol −1 , respectively. interaction Fe during forms a Fe–Cr solid solution, loosens internal structure...
Herein, the optimized process parameters for preparation of vanadium‐titanium magnetite (VTM) pellets are determined, and an efficient green utilization technology VTM based on integration oxidation roasting‐hydrogen‐based shaft furnace direct reduction is established. The results indicate that preferable oxidized pre‐reduced can be prepared by preheating at 925 °C 18 min roasting 1200 25 min, followed temperature 1050 atmosphere 4% CO 2 H /CO = 8. corresponding compressive strength...
This study investigates the effect of TiO 2 on oxidation kinetic mechanism iron ore concentrate under nonisothermal conditions. Based fact that iron‐containing materials are mainly smelted in form pellets, microstructure evolution pellets with different additions during is studied to verify accuracy analysis results. The results show reaction model describing at stages I and II. increase increases E worsens conditions phenomenon caused by Fe–Ti solid solution embedded hematite particles...
To realize the efficient and clean comprehensive utilization of vanadium–titanium magnetite in Baima mining area Panzhihua, an innovative hydrogen‐based shaft furnace direct reduction followed by a melting separation process is proposed. In this study, behaviors affected temperature, time, basicity, C/O (mole ratio carbon to reducible oxygen) are systematically investigated. The chemical composition, phase microstructure slag using modern analytical techniques such as X‐ray diffraction,...
