Device for preheating objects, particularly aluminum strands, rods, or pins, as well as a system having such a device

Abstract

In the case of a device ( 1 ) for preheating objects (S), particularly aluminum strands, rods, or pins, which device precedes a furnace ( 2 ) for the actual heating of the objects (S), and in which device preheating takes place using waste gases of the furnace ( 2 ) for actual heating of the objects (S), it is provided that the device has a housing ( 5 ) that is configured in the manner of a magazine, to accommodate and preheat multiple objects (S) simultaneously, as a supply, which objects can be passed to the housing ( 5 ) by way of a closable inlet opening element ( 7 ) and can be removed from it again analogously, preheated, by way of a closable outlet opening element ( 9 ), whereby the waste gases of the furnace ( 2 ) for actual heating of the objects (S) get into the housing ( 5 ) by way of at least one feed channel ( 3 ), to preheat the objects. The device ( 1 ) is furthermore integrated into a system (A) for processing the objects (S).

1 . Device ( 1 ) for preheating objects (S), particularly aluminum strands, rods, or pins, which device precedes a furnace ( 2 ) for the actual heating of the objects (S), and in which device preheating takes place using waste gases of the furnace ( 2 ) for actual heating of the objects (S), wherein the device has a housing ( 5 ) that is configured in the manner of a magazine, to accommodate and preheat multiple objects (S) simultaneously, as a supply, which objects can be passed to the housing ( 5 ) by way of a closable inlet opening element ( 7 ) and can be removed from it again analogously, preheated, by way of a closable outlet opening element ( 9 ), whereby the waste gases of the furnace ( 2 ) for actual heating of the objects (S) get into the housing ( 5 ) by way of at least one feed channel ( 3 ), to preheat the objects. 
     
     
         2 . Device according to  claim 1 , wherein the housing ( 5 ) is configured in the manner of a magazine, in such a manner that the objects (S) are disposed sequentially in it and their transport takes place by means of a pushing cylinder ( 8 ). 
     
     
         3 . Device according to  claim 1 , wherein the housing ( 5 ) is configured in the manner of a magazine, in such a manner that the objects (S) are disposed sequentially in it, on a slanted plane, in which the inlet opening element ( 7 ) is disposed higher relative to the outlet opening element ( 9 ), so that transport of the objects (S) takes place by means of gravity. 
     
     
         4 . Device according to  claim 2 , wherein when an inlet opening element ( 7 ) and/or outlet opening element ( 9 ) is open, at least one grid-like holding element ( 10 ) is provided for holding the sequentially disposed objects (S) in place, in each instance. 
     
     
         5 . System (A) for processing objects (S), particularly aluminum strands, rods, or pins, which system comprises at least one device ( 1 ) for initial heating of the objects (S), a furnace ( 2 ) for actually heating the objects that follows this device ( 1 ) for initial heating of the objects (S), as well as a processing unit that follows this furnace ( 2 ), and at least one transport unit ( 6 ) for the objects (S) in the region of the device ( 1 ) for preheating, the furnace ( 2 ), and the processing unit, in each instance, whereby the initial heating of the objects (S) takes place in the device ( 1 ) provided for this purpose, using waste gases of the furnace ( 2 ), wherein the device for initial heating ( 1 ) is configured according to  claim 1 .
