Apparatus to move and preheat metal material

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...
