摘要
为进一步研究矿热炉设计理论,通过对原始文献的系统分析,对安德烈公式的准确表述、安德烈公式测算方法以及物理意义进行了系统研究。研究表明,安德烈公式建立的假设前提包括:炉内电能全部在电极端部往下的熔炼区释放;将矿热炉炉内阻抗看成纯电阻,并假定炉内电阻等于电极端部到炉底之间的电阻。另外,测算操作电阻时选择的冶炼状态还存在分歧。
In order to further study design theory for the submerged arc furnace, it makes a systematic research from original references, accurate Andreae formulation and its measure method, physical significance. The study concludes that the establishment of formula is on the following hypothesis： All the electrical energy in the furnace were released in the smelting zone below the electrode tip; furnace impedance were deemed as pure resistance, furnace resistance were assumed equal to the resistance between electrode tip and furnace bottom. In addition, there is ambiguity in choosing melting state for measuring operation resistance.
