A thermomechanical control process consisting of slab reheating, controlled rolling, and accelerated cooling has been adopted at the plate mill, Bhilai Steel Plant, India for achieving high strength and toughness in C-Mn and microalloyed steels while keeping the mechanical properties and the flatness constant. A mathematical model has been developed to predict the temperature distribution in the plate during accelerated cooling, taking into account the heat generation of the phase transformation. EVects of chemistry and mill parameters on ferrite grain refinement are explained in terms of nucleation and growth rate.MST /3978
Due to increased load demand, the power system developers are encouraged to
meet power quality requirements. Using harmonic filter and capacitor bank is
one of the essential solutions in mitigating power quality issues. This
research aims to mitigate harmonics and improve the voltage in distribution
systems by using ETAP. For this purpose, a distribution system in Homs city
is considered, which is a part of Syrian power system. The capacitor banks
are designed using numerical analysis and Optimal Capacitor Placement (OCP).
The results indicate that this approach enhances the voltage profile, which
is reflected in some buses. The voltage profile is effectively improved on
several buses, and power losses are significantly reduced. The Total
Harmonic Distortions (THDs) and Individual Harmonic Distortions (IHDs) of
the subjected buses are reduced. Moreover, the power factor is improved from
0.877 to 0.926 for the studied system.
were used for the curing process. Results showed strong interactions between the process variables mentioned above. The process was anoptimization to achieve a combination of T gel and T peak within the regime of experimentation.Mathematical models were developed using regression for both peak temperature and gel time. Confirmatory experiments were performed to validate the predicted results.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
