    摘要: An apparatus to move and preheat metal material (M) to be fed to a container comprises a containing structure, having an internal compartment and provided with a support wall, a conveyor for the material (M), a fume transit section whose volume reduces as it is distanced from said container along the longitudinal development of said containing structure, and a collector for hot fumes (F) whose volume increases in a manner correlated to said reduction in the fume transit section. The collector is located below said conveyor inside the internal compartment essentially along the entire longitudinal development of said containing structure. Moreover, one or more through apertures are made in said support wall to put the conveyor and the collector into fluidic connection.

    摘要: An arc furnace automatic feeding device comprises an automatic distributing device, wherein the automatic distributing device comprises a distributing groove, and at least one step-like distributing section which tilts from high to low along a material delivery direction is provided at the bottom of the distributing groove; and further comprises a thermal feeding device, a feeding device, and an uploading device. The automatic distributing device enables forward tossing of the materials when falling down, which eliminates the problem that the materials are difficult to be scattered in overall movement, so that the materials can be effectively scattered by vibration, the stacked materials can be uniformly and continuously distributed in the groove, and the waste steel piling problem of the materials is prevented from occurring at a throat portion of the feeding device. Different thermal feeding devices have advantages such as good material preheating effect and environment friendliness. The uploading device does not require a crane, so the operation is convenient, of high safety, and suitable for high-frequency material uploading; and the uploading device can satisfy operation frequency demands of continuous feeding for smelting of medium to large arc furnaces.
