FORFARANDE FOR BESTEMNING AV DE METALLURGISKA TILLSTANDEN, SASOM DRIFTTEMPERATUR ELLER DYLIKT, I EN ELEKTRISK LJUSBAGSUGN

摘要

A method for determining the operating conditions in electrical arc furnaces by measurement of an electrical parameter which is varied by the metallurgical processes being carried out. This method may be utilized either with furnaces which operate with an open electrical arc above a molten bath or with furnaces which operate with submerged electrodes. The measured electrical parameter is processed to form a signal for controlling the temperature in the furnace, or the supply of raw materials to the furnace, and/or the carbon/oxide ratio in the raw material mixture in the furnace.
