China’s graphite electrode quality standard (YB/T 4090 – 2000) has defined six physical and chemical indicators for the quality evaluation of uhp graphite electrode. Among them, Electrical Resistivity, Bending Strength, Elastic Modulus, Bulk Density and CTE(coefficient of thermal expansion) are used as indicators for quality assessment, and ash is used as a reference index.
