Knowing molten state of the scrap in the electric arc furnace is very important for process control. Because of the harsh environment of the furnace new measurement techniques must be developed to measure the molten state. This paper looks at vibrations emitted from the furnace with the use of accelerometers, looking for correlations with the molten state. It was found that 87% of the heats have increasing vibrations with the respect to time. Also, 47% of the heats have a coefficient of determination (R2) of more than 0.5 between vibrations and time. Further evaluation must be conducted to see if this can be related to the scrap content in the furnace.
