矿热炉碳素原料导电行为研究

摘要

矿热炉炉料的导电主要靠混合炉料中的碳素原料来导电.本文对矿热炉碳素原料的导电行为进行了研究,对均一粒度焦炭电阻率和混合粒度焦炭堆积电阻率进行了测量,建立了焦炭电阻率与当量直径关系的模型.通过实测数据,得到某电石厂焦炭电阻率与当量直径关系的模型为ρ焦炭= 0.0646r焦炭-0.4569.%The conductivity of a submerged arc furnace is conductive mainly by the carbon charging stock. In this paper, the conductive behavior of carbon charging stock is studied, the piled resistivity of coke with uniform grain size and mixed grain size is measured, the model which describes the relevance between the resistivity of coke and the equivalent diameter is constructed. Based on the measured data, the model which describes the relevance between the resistivity of coke and the equivalent diameter of a certain Calcium Carbide Factory is constructed as ρ焦炭= 0.0646r焦炭-0.4569.
