摘　　要：试验了直流电弧炉炉底用石墨12％～14％，镁砂86％～88％导电捣打料，在不同状态下的电阻车和耐压强度，并用岩相分析研究了试样的显微结构;50kg直流电弧炉炼钢试验表明，该导电捣打料具有良好的导电性和耐侵蚀性。Under different conditions, the electrical resistivity and compressive strength of conductive ramming mixes 12%~14% graphite and 86%~88% magnesia for DC electric arc furnace bottom were tested, and the microstructure of samples was investigated by petrographic analysis. The experiment results of steelmaking using 50 kg DC EAF show that the conductive ramming mixes has excellent conductive and anti-etching properties.
