分析了各种多电极的熔炼过程,以便按照其基本电气行为,找出它们的差别和特点。也打算在炉料热性质的基础上建立一种能够确定炉子尺寸的基本理论。各种主要类型电炉冶炼过程表现出有以下这些电气特性:恒定的熔体电导率(熔化氧化物);恒定的炉料电导(碳化钙、生铁和磷);恒定的相间电压(铁合金);恒定的电弧电导(铜和炼钢)。炉内进行某一冶炼过程所需截面积,看来取决于炉料进入熔体时的温度下炉料的热扩散特性。由于下列原因,这些电气和热力特性是很重要的;为了控制熔体粘度;为了提供设备扩大时所需数据;为了选择供电的部件;为了确定过程分析中的电气参数。
Various multi-electrode smelting processes were analyzed to find out their differences and characteristics according to their basic electrical behavior. It is also intended to establish a basic theory that determines the size of the furnace based on the thermal properties of the charge. Various major types of electric furnace smelting processes exhibit the following electrical characteristics: constant melt conductivity (molten oxide); constant charge conductance (calcium carbide, pig iron and phosphorus); constant interphase voltage (ferroalloy); constant Arc Conductivity (Copper and Steelmaking). The required cross-sectional area for a smelting process in the furnace appears to depend on the thermal diffusivity of the charge at the temperature at which the charge enters the melt. These electrical and thermal characteristics are important for the following reasons; in order to control the melt viscosity; to provide the data required for the expansion of the equipment; in order to select the parts to be powered; in order to determine the electrical parameters in the process analysis.
