用于预加热、转变和熔融金属炉料的方法以及相关设备
摘要：
本发明涉及用于预加热、转变和熔融金属炉料的方法以及相关设备。用于在电弧炉(12)和与该电弧炉相联的烟道(11)内预加热、转变和熔融包括金属废料的金属炉料的方法，该烟道传送、预加热和排放所述废料。炉(12)包括炉膛(13)和电极(15)穿过其中的顶(14)。本方法包括至少定期称炉(12)的重量以便检测该炉(12)本身中存在的排出的废料的量，至少定期检测该炉(12)内熔池的温度，以及至少通过称重来检测排放输送到炉(12)内的废料并对其进行调节，以便将所述熔池的温度保持在预定值附近。
摘要（英）：

Method and plant for pre-heating, transforming and melting a metal charge comprising metal scrap, in an electric arc furnace (12) associated with a tunnel (11) to transport, pre-heat and discharge the scrap. The furnace (12) comprises a hearth (13) and a roof (14) through which the electrodes (15) pass. The method provides that the furnace (12) is weighed at least periodically in order to detect the quantity of discharged scrap present inside the furnace (12) itself, that the temperature of the liquid bath inside the furnace (12) is detected at least periodically and that at least the discharge delivery of the scrap inside the furnace (12) is detected by weighing and is regulated in order to maintain the temperature of the liquid bath around a pre-determined value.
