Abstract
The object of this project was to establish the extent to which the various forms of energy can be replaced by each others as well as what will be their corresponding efficiency as a substitute for electricity in the electric arc furnace process. A further object was to establish the possibilities for decreasing the total energy consumption of the melt shop and to create process models for melting and refining in order to be able to predict the correct moments for scrap charging, sampling and temperature measurements as well as for tapping of the furnace. With investigations and practical experiments regarding preheating, melt-down and refining the interchangeability of the different forms of energy has been established. With these results a basis has been created for the energy - and temperature models. The models are based on the assumption that when the scrap has received a certain amount of energy or the temperature of the charge has reached a certain level the furnace is ready to accept the next scrap basket or that the all-melt has been reached. Further, as far as the refining is concerned the final models are able to instruct the furnace operators as to which transformer tap
