WIRE- HEATING OVEN.
- mamma med settantaic, i925. serial no. 55,929.
This invention relates to im rovements in furnaces and Amore particular y to animproved oven in -`which coils ori bundles of Wire maybe heated for Vdrying'after they 5 have been pickled to remove scale.
It is an. object ofthe invention to provide an oven for the purpose specified which shall be simple in construction, etlicient in o eration, and which may be heated with uid Another object is to -provide a furnace construction in which the oven may be heated in such amanner that the hot air in the oven mayv circulate 'freely around the 5 workto be dried or heated, the circulation'Y of air being set up by convection currents within the oven. j j.
A stillv further object is to provide an oven which may be heated by means of a 29 longitudinally extending tunnel arranged at the bottom of the oven, means being rovided for leading the products of com ustion through a radiator arranged within'the oven in order to more efectually utilize the heating value of the fuel and to assist in setting-up convection currents within the oven.
The above and other objects will appear from the detailed description taken in connection with the accompanying drawings lforming part of this specification.
Referrlng to the drawings: 1
Figure 1 is a vertical longitudinal section through the improved furnace or wire-heatingoven, showing the preferred arrangement of parts and how the radiator is disposed within the oven; i
Figure v2 isa vertical transverse section taken on line' 2--2 of Fig. 1 and showing the base of the furnace provided with spaced piers or runways on which wire-laden, and vwheeled vehicles (not shown) are adapted to vbe supported, and
Fig.A 3 isa vertical transverse section taken on line `3-3 of Fig. 1,- showing constructional features of the furnace. y In the drawings, the sidewalls of the .furnace or oven are indicated at 10, the roof or .arch of the same at 12,`and1the doors at the ends of the oven at 1 4. @The side walls4 of 18. Extending longitudinally of the base is a` flue or tunnel,- generally indicated "at 20, this flue being built of suitable refractory material and having an opening 22 at one vend through which lluid fuel such as oil or riser 30, which is in connection with a suitthe furnace are supported on a suitable base.
may be entered into the tunnel, any suitable type of burner being utilizedl for introducing the fuel into the tunnel. I
yThe .products of combustion` formed by the burning fuel pass out of the flue or tunnel through an opening or outlet 24 atv the far end thereof. Disposed over the opening 24 is an elbow 26 and connected with the elbow is a radiator 28, preferably in the form of a pipe or'conduit, bent back upon itself, the lower run of the pipe being disposed somewhat above .the top ofthe l tunnel. The gases passing through the radiator pass-from the same through a suit-able able flue 32 leading to a stack. A damper 34 is preferably provided in the riser togper.- mit control of the rate of passa e of the products of combustion through h e' radiator. i
That end of the radiator farthest away from the tunnel outlet 24 is preferably -provided with a conduit .36 which leads from the tunnel adjacent the firing end thereof to permit by-passing of some of the hot gases to the adjacent' portion of the radiator. This conduitl is preferably provided with a damper 38 for controlling the flow of the hot gases into the radiator. The radiator is suspended in a vertical plane Within the oven in any suitableiman ner, as by means of strap-hangers 40 Ysus-` pended from cross-rods 42. The radiator and tunnel are located midway between the walls 10.0f the oven which is thus divided into two equal parts, one part oneach side of 4the radiator andthe tunnel.
' 'Rising from 4the base of the furnace at i `that the wire or work to be heated will be` I `placed on the wheeled vehicles, such` as trucks. The tracks are conveniently con- 100 nected by transverse ties48, as indicated in Fig; 2. The piers' are spaced from each other to form channels 49 and `from the adv jacent side walls of the oven to form chan nels' 49.
. los Referring to Figs. 2 and 3, it will be noted thatthe side walls of thev tunnel 20 are not of the same thickness throughout their length, the walls being thicker in the first part of the tunnel 'so asbetter to withstand 110 the high temperature of the lburning gases, the thickened portion of the walls being indicated at 50. The tunnel 20 is preferably capped with anarch 52, which is of equal length with the thickened side walls, That portion of the tunnel having the thickened side walls 50 and the arch 52 may properly be termed the combustion chamber of the tunnel. The other ortion of the tunnel may conveniently be termed the expansion chamber of the tunnel. The side walls of the expansion chamber are indicated at 54 and the cover tile at 56. These arts are preferably of less thickness than t e corresponding parts of the combustion-chamberpart of the tunnel. It will also be noted that the expansion chamber is of larger mes-section area than the combustion chamer. I
The piers 44 nearest the tunnel are contiguous the combustion-chamber-part.thereof, but are in spaced relation to the' other part whereby channels 57 are formed. The piers are provided with lateral passages 58 to permit free circulation of the heated air between the various channels.v
By reference to Fig. 1 it will be noted that the tracks 46 are preferably arranged on a gradient so as to facilitate the'movement of the trucks or wheeled vehicles through the oven.
What is claimed is:
1. A furnace comprising an oven, a tunnel in which fuel may be burned for heating .the oven extending longitudinally of the oven midway its sides and'beneath the floor thereof, means for leading the products of combustion formed in said' tunnel through the oven for further heating'the latter comprising a radiator extending from the top of the flue to the top of the oven, and open top channels extending parallel -to the flue in the fioor of the oven on both sides of 'the tunnel and connected by lateral passages whereby air may circulate freely along the sides of the tunnel to be. heated thereby and may circulate below work supported on the floor across said channels.
2. A furnace comprising an oven, 'a tunnel in which fuel may be burned for heating the oven extending longitudinally of the same midway its sides, means for supporting the work to he heated comprising elevated tracks lthe tops of which are substantially on a level with the top of the tunnel, said tracks being in spaced relation with respect toeach other and the sides of the oven and the sides of the tunnel whereby air may freely circulatebelow the work supported on`the tracks and may come in contact with the sides of the tunnel to be heated thereby, and means for leading the products of combustion formed ir said tunnel through the oven for further heating the latter, said means comprising a radiator extending from the top of the tunnel to the roof of the oven and through whichl the products of `combustion pass on their way to the atmosphere.
