Abstract

The invention provides a scrap preheater, an arc melting device and a preheating method. The scrap preheater comprises a vertical shaft, an unloader, a material transfer trolley and a guide roll. A feeding inlet is arranged at the upper end of the vertical shaft, and a discharging outlet is arranged on the side wall of the lower end of the vertical shaft. The unloader is arranged in the vertical shaft and can move relative to the vertical shaft in the vertical direction. The unloader is provided with an upper surface which inclines towards the discharging outlet. The material transfer trolleycan transfer materials in a vibrating manner, and an inlet end of the material transfer trolley is connected with the discharging outlet. The guide roll is arranged at the position of the dischargingoutlet and is located on the upper side of an inlet end of the material transfer trolley, and the opening degree of the discharging outlet can be controlled by the guide roll. The scrap preheater, thearc melting device and the preheating method have the advantages that the unloader can be adjusted in the height direction, different unloading speeds can be implemented by adjusting the height of the unloader and the position of the guide roll, the material transfer trolley can horizontally move, the landing position of scrap steel can be under control by adjusting the vibrating frequency and the vibrating magnitude of the material transfer trolley, and it is achieved that the scrap steel is fed continuously.

Description

technical field [0001] The invention relates to the technical field of metallurgy, in particular to a scrap steel preheating device, arc melting equipment and a preheating method. Background technique [0002] Energy saving, consumption reduction, and environmental protection in electric arc furnace steelmaking have always been one of the core technologies in the development of global electric arc furnace steelmaking technology. [0003] In the traditional electric arc furnace for steelmaking, steel scrap is loaded from the top of the furnace into two to three times, relying on the arc generated between the electrode and the scrap steel to melt the scrap steel. Therefore, the traditional electric arc furnace can only send electricity to the furnace intermittently, and the power will be cut off after a period of time, and the furnace cover will be unscrewed to charge, which greatly reduces the productivity of the electric arc furnace and increases the heat loss and energy con...
