Embodiment Construction

[0047] Reference is made in detail below to the various forms of embodiments of the invention, one or more examples of which are illustrated in the accompanying drawings. Each example is given by way of illustration of the invention and none should be construed as limitation of the invention. For example, features shown and described may be used as part of one embodiment form or in connection with other forms of embodiment to form another embodiment form. It should be understood that the present invention includes all such modifications and variations.

[0048] figure 1 It is used to describe an embodiment form of a device 10 for moving and preheating a metal material M, in particular for a metallurgical smelting process.

[0049] The metal mass M can be melted by a smelting process in a smelting furnace 11 of known type, so it will not be described in detail in this description, but only its parts that have an effect on the device 10 .

[0050] Melting furnace 11, such as ...

Abstract

An apparatus (10) to move and preheat metal material (M) to be fed to a container (12) comprises a containing structure (14), having an internal compartment (14a) and provided with a support wall (18), a conveyor (20) for the material (M), a fume transit section (21) whose volume reduces as it is distanced from said container (12) along the longitudinal development of said containing structure (14), and a collector (22) for hot fumes (F) whose volume increases in a manner correlated to said reduction in the fume transit section (21). The collector (22) is located below said conveyor (20) inside the internal compartment (14a) essentially along the entire longitudinal development of said containing structure (14). Moreover, one or more through apertures (1 18a- 1 18h) are made in said support wall (18) to put the conveyor (20) and the collector (22) into fluidic connection.

Description

technical field [0001] The invention relates to a device usable in the field of metallurgy and / or steelmaking for moving and preheating metal materials to be delivered to containers. [0002] The device according to the invention is used to heat metal material using hot flue gases from, for example, a furnace connected to the device and to convey it to a container, which may be scrap for discontinuous or "batch" feeding of said furnace The loading basket or, for example, in the case of a direct continuous feed, the shell of the furnace. Background technique [0003] In the field of metallurgy, it is known to utilize vibrating or moving conveyors with the function of conveying metal material to temporary storage containers or furnaces. [0004] The metal material can be scrap iron, hot or cold sponge iron (DRI, direct reduced iron), chilled cast iron in bricks or briquettes or other metal materials and can be conveyed to holding baskets or The shell of a furnace in a contin...
