Application 4filed February 3, 19.12. Serial No. 675,297.
of Ohio, l Sheridan, 'in the county of Lebanon and State of Pennsylvania, Vhave invented cer! tain new and luseful Improvements in Con'- tlnuous Heatlng-Furnaces; and we do hereby declare the following to be a full, clear,v
and exact description of the invention, such y as will enable others skilled in the art to or billets are automatically which it appertains to make and use the \same.
This invention relates to that class of continuous heating furnaces wherein vthe ingots the zone of highest heat, and 'the primary object of our invention is to enable the heat to be concentrated and intensified at or near' the point of discharge or to be distributed generally. throughoutthe furnace, according as conditions may require.
The invention will be hereinafter fully set forthand particularly pointed out in the claims. A y
In Vthe accompanying drawings, Figure l is a vertical longitudinal sectional view. Fig. 2 is a horizontal vvsectional view. Fig. 3 is a side elevation of the fuel attachment.
We have shown our invention applied to -a known-type of furnace which embodies the usual track 1 extending longitudinally of the heating chamber 2 from the charging ilrlet 3 to the discharge outlet 4, the track being inclined at 5 to effect the automatic discharge of the billets frdm the furnace when inthe zone of highest heat. The billets are pushed along the tracks by push- 0 ing mechanism of known construction. At-
' lstructural beams.
The air and gas are fed into the mixing chamber in line with the hea-ting chamber. The air is introducedJ through nozzles 8, and the gas through nozzles 9, and both project into openin sin the end wall of the mixing chamber. e have shown three air contro-l of the operator. discharged from nozzles and a" corresponding number of gas nozzles, the former leading from an airsupply boX'lO, and the gas nozzles from a gas-supply box 12. Air is supplied to box lOby pipes 13, andf gas to boX 12 by pipes 14. Each nozzle 8 is shown as having atits 'receiving end an ordinary inlet valve 15,
and each nozzle 9 a similar valve 16. These valves regulate the volume of air and gas admitted to the furnace.
' For the purpose of controlling the direction -of the air and gas, that is to say, the plane of the direction thereof into the mixing and heating'C chambers, each nozzle is equipped withI deecting means within the In each nozzle 8 we locate a deflector 17, and in each nozzle 9 a deflector 18, respectively controlled by levers 19 and 20. Under normal conditions the de-flectors 18 will lie on the bottoms of t-he gas-nozzle so as to allow an uninterrupted llow of gas in substantially direct chambers, and at the same time the 'airdefletors 17 will be fully opened and lie Iagainst the tops of the air-nozzles.
If, 1n practice, it be found that the ingots or billets have not attained the necessary temperature before being discharged, this result may be secured by intensifying as Well as concentrating the flame on the in gots just before they reach the inclined track. This is accomplished by lowering t-he airdeflectors 17 a few inches, as indicated in dottedv lines, Fig. 1. lThis will result in concentrating on the ingots near the point of discharge a very intense Haine which will quickly bring the lsteel up to the desired heat. If, on the other hand, it is found that the steel is being heated to too great a degree at or about the point of discharge, the operator raises the air-deflectors 17 against the tops ,of the air nozzles and at the same time raises the gas-dence tors 18 about half Way as, shown in dotted lines, Fig. 1. This will result in the gaseous i alinement with the mixing and heating fuel being directed. against the roof of Ythe heating chamber and over the billets near' the discharge outlet, and the` heat will be thrown back into the chamber toward the charging inlet.' Vithin cert-ain limits the extent'to which the heat may be thus thrown back into the heating-chamber is controlled by the operator b merely adjusting the gas-denectors.
We claim as our invention:
l. In a continuous heating furnace having a charging inlet at one end and a discharge outlet at or near the other end, supports' for ingots or billets extendingthrough the heating chamber from the charging inlet tothe discharge outlet, a mixing chamber in alinement Wlth said heating chamber, means for admitting gaseous fuel into said -mixing chamber in line with the heating chamber, and means for'changing the plane of enrance of the gaseous fuel into said cham- E2. In a continuous heating furnace having a charging inlet at one end and a discharge outlet at or near the other end, supports for ingots or billets extending through the heating chamber from the charging linlet to the discharge outlet, a mixing chamber in alinement with said heating chamber, means for admitting gas to said mixing chambery in line with the'heating chamber, means. for likewise admitting airto said mixing chamber, and means forlregulating the plane of entrance of the air.
3. In a continuous heating furnace having a charging inlet at one end and a discharge outlet at or `near the other end, supports for ingots or billets extending through the heating 'chamber from the charging inlet to the discharge outlet, a mixing chamber in alinement With said heating chamber, means for admitting gas to .said mixing chamber'in line with the heating chamber, means for likewise admitting air to said mixing chamber, and means for regulating the planb of entrance of the gas.
- 4. In a continuous heating furnace having a charging inlet at one end and a discharge outlet at or near lthe other end, supports for ingots or billetsextending through the heating chamber from the charging inlet to the dischar e outlet, a mixing chamber in `alinement W1th said' heating chamber, means'forJ admitting gas to said` mixingchamber in a charging inlet at one end and a discharge outlet at or near the other end, supports for ingots orbillets extending through the heat- L ing chamberfrom the` charging inlet'to the discharge outlet, a mixing chamber in aline- `ment with said heatinghamber, air inlets in"1said mixing chamber inline With said heating chamber, gas inlets in said mixing chamber also in line with said heating chamber, oneseries of inlets being above the other, separate deflectors for the air. and gas inlets, and means for operating such deflectors' to regulate the plane of entrance of the gaseous fuel into the mixing and heatin chambers.
