    • Procedure and apparatus are utilized for charging scrap metal in accordance with its density to cushion the impact involved in loading it into a vessel such as a preheating silo, and for enabling an accurate control of the quantity of preheated scrap charged based on weighing it before it has been preheated. A preheating silo having upper and lower compartments and a separating partition therebetween utilizes a flow of hot furnace gases into a lower compartment, upwardly through the partition, and into and out of an upper compartment to preheat the scrap from the standpoint of providing a higher temperature portion in the lower compartment that may be directly charged into the furnace and a lower temperature portion in the upper compartment that is to be subjected to further treatment to bring it up to a furnace charging temperature. The compartments of the preheating silo are utilized interchangeably as cold scrap receiving and as hot scrap delivering chambers.
    • 程序和设备用于根据其密度对废金属进行充电,以缓冲将其装载到诸如预热料仓之类的容器中的冲击,并且能够准确地控制在其之前称重的预热废料的数量 已经预热。 具有上隔室和下隔室的预热料仓和其间的分隔隔板通过向上通过分隔件的热室气体流进入上隔室并进出上隔室以从废料提供更高的温度 可以直接装入炉中的下隔室中的部分,以及要进行进一步处理以使其达到炉充气温度的上隔室中的较低温度部分。 预热料仓的隔室可互换使用,作为冷废料接收和热废料输送室。
