摘要

摘要：提出了一种确定电弧炉（EAF）动态电弧模式数学模型参数的方法，电弧作为电路的一个元件，将从供电网络中消耗的电能转化为加热周围材料的热能。电弧的稳态电流-电压特性和时间常数是模型所必需的，通过动态电流-电压特性来恢复，动态电流-电压特性可以通过先验的理论数据设置或实验确定。

Restoration of the Parameters of a Dynamic Arc Model for an Electric Arc Furnace

Abstract—An approach is proposed to determine the parameters of a mathematical model for the dynamic arc modes in an electric arc furnace (EAF) by considering an arc as an element of an electrical circuit, which converts electrical energy consumed from the supply network into thermal energy for heating the surrounding materials. The steady-state current–voltage characteristic and the time constant of an arc, which are necessary for the model, are restored using a dynamic current–voltage characteristic, which can be set using a priori theoretical data or determined experimentally.

期刊介绍： Russian Metallurgy (Metally) publishes results of original experimental and theoretical research in the form of reviews and regular articles devoted to topical problems of metallurgy, physical metallurgy, and treatment of ferrous, nonferrous, rare, and other metals and alloys, intermetallic compounds, and metallic composite materials. The journal focuses on physicochemical properties of metallurgical materials (ores, slags, matters, and melts of metals and alloys); physicochemical processes (thermodynamics and kinetics of pyrometallurgical, hydrometallurgical, electrochemical, and other processes); theoretical metallurgy; metal forming; thermoplastic and thermochemical treatment; computation and experimental determination of phase diagrams and thermokinetic diagrams; mechanisms and kinetics of phase transitions in metallic materials; relations between the chemical composition, phase and structural states of materials and their physicochemical and service properties; interaction between metallic materials and external media; and effects of radiation on these materials.
