The steel industry has been forced to switch from the traditional blast furnace electric arc (EAF) process reduce carbon emissions. However, EAF still relies entirely on operators’ proficiency determine electrical power input. This study aims enhance efficiency of by predicting tap temperature in real time through a data-driven approach and applying system that automatically sets input amount p...

Silicon is produced in submerged arc furnaces which are heated by electric currents passing through the furnace. It important to understand distribution of heating within furnace order accurately model silicon production process, yet many existing studies neglect aspects this current flow. In present paper, we formulate a that couples electrical thermal, material flow and chemical processes We ...

A review of the control laws (models) alternating current arc steelmaking furnaces’ (ASF) electric modes (EM) is carried out. phase-symmetric three-component additive fuzzy model electrode movement signal formation proposed. synthesis inference systems based on Sugeno for implementation proposed law length performed. structural computer Simulink EM system in a high-power furnace DSP-200 type wi...

During a run of the Common Programme Three of the EISCAT radar the splitting of an auroral arc was observed by high time-resolution, ground-based cameras when the UHF radar beam was close to the arc. The evening eastward electrojet situation with a largescale northward ionospheric electric field was disturbed by the intrusion of a convection channel with southward electric field from the east. ...

The non-linear loads include rectifiers, blenders, electric drills, UPS, computer, printer, TV’s, variable speed drivers, arc furnaces and high power electronic equipment comprising high power semiconductors i.e thyristorised Converters, Inverters etc. It is well known that any deviation from a perfect sin-wave is an indication of the presence of harmonics in the power system. Hence, a pure alt...

The heavy electrical power draw of electric arc furnaces (EAF) proposes them as prime candidates for economically viable decentralized grid operation, provided they are able to operate efficiently and flexibly in response and in anticipation of fluctuations in price and local renewable energy availability. For this purpose, we consider a hypothetical industrial micro-grid consisting of a wind p...

Abstract: In this work, a new method for calculating the parameters of electric arc model for SF6 power circuit breaker is proposed. The methodology consists in the optimization of a theoretical function with respect to a group of model parameters in order to achieve a better approximation to a set of experimental data. The theoretical function is an asymptotic solution of the equation for the ...
