Der auf beiliegender Zeichnung durch Fig. ι bis 4 im Längsschnitt, Querschnitt und Grundrifs dargestellte Doppel-Platinenwä'rmofen mit nur einem darüber liegenden Blechwärmherd verfolgt den Zweck, sowohl kurze wie lange Bleche von unten herauf intensiver und von oben herab gleichmä'fsiger zu wärmen in viel kürzerer Zeit, als es mit den heute benutzten Glühofen dieser Art möglich ist. Alle neueren combinirten Platinen- und Blechglühöfen, woselbst der Platinenwärmherd vor oder über dem Blechwärmherd liegt, wärmen thatsächlich den letzteren von unten herauf viel zu wenig, wodurch die untersten Bleche in dem zu wärmenden Blechpack beim Glühen noch schwarz sind, während die obersten Bleche sehr an Zunderbildung leiden und verbrennen. Ebenso haben die Oefen noch den Nachtheil an sich, dafs die Flammeneinwirkung nur von einer Kopfseite des Blechherdes stattfindet, wodurch beim Wärmen langer Bleche von 4 bis 6 m das vordere Blechende warm ist, während das hintere Ende von 2 bis 2Y₂ m noch schwarz ist. Dieses ungleichmäfsige Wärmen wird durch schärferes Stochen des ganzen Ofens beseitigt, oder die langen Tafeln Blech werden aus dem Ofen herausgezogen, gewendet und mit dem warmen Ende wieder in denselben geschoben, und dann wird das andere kalte Blechende nachgewärmt, was ebenfalls wieder mehr Kohlen bedarf.The double-plate heating furnace shown in longitudinal section, cross-section and outline in the accompanying drawing by FIGS in a much shorter time than is possible with the annealing furnace of this type used today. All newer combined sheet and sheet metal annealing furnaces, where the sheet heating hearth is in front of or above the sheet metal heating hearth, actually heat the latter far too little from below, as a result of which the lowest sheets in the sheet metal pack to be heated are still black during the annealing, while the uppermost sheets are very on Suffering from scaling and burning. The stoves also have the disadvantage that the flames only come into play from one side of the head of the tin hearth, so that when long sheets of 4 to 6 m are heated, the front end of the sheet is warm, while the rear end of 2 to 2 and ₂ m is still black . This uneven heating is eliminated by piercing the whole oven more sharply, or the long sheets of sheet metal are pulled out of the oven, turned and pushed back into the oven with the warm end, and then the other cold sheet end is reheated, which also requires more coal.

Der neue Ofen besteht nun aus zwei Platinwärmherden α und a¹ mit den davor liegenden Stochrosten b und b\ die durch die Thüren ρ und p¹ beschickt werden, während beide Platinenherde mit Thüröffhungen r¹ und r zum Einschieben der Platinen versehen sind. Beide Herde α und a^l liegen fast auf einer Höhe mit der Hüttensohle, während die Stochsohle derselben etwa 70 bis 80 cm unter der Hüttensohle liegt; die punktirte Linie η η der Fig. 1 giebt diese Stochsohle mit den Zugangsrampen an. Ueber beiden Platinenherden liegt der gemeinsame Blechwärmherd ee¹, der vorn rechts durch die mit Schieber s versehenen Oeffnungen d direct mit dem Platinenherd a in Verbindung steht, während jeder Platinenherd durch die Heizkanäie c e und C¹C¹ noch von oben durch die Züge f und y¹, sowie deren Austrittsöffnungen m und m¹ mit dem Blechwärmherdtheil e bezw. e¹ in Verbindung steht. Am linken Ende des Blechherdes befinden sich die eigentlichen Feuergasabzugsöffnungen g, welche durch die Schieber s¹ ebenfalls regulirbar sind; erstere münden in den Hauptkanal h, wodurch die Feuerabzugsgase in den Fuchs i und von da in den Schornstein geleitet werden. Die Seitenheizkanäle c und c^l sind ebenfalls zum Reguliren der Flammenwirkung durch die Schieber o¹ eingerichtet; die Thür t ist dieselbe für den ständigen Gebrauch, während die Thür t¹ auch das Herausnehmen ganz langer Bleche nach hinten aus dem Herd gestattet. Der Raum k und k¹ unter den Platinenherden dient zur Lagerung der Stochkohlen.The new furnace now consists of two platinum heating stoves α and a ¹ with the stochromatic grates b and b \ in front of them, which are fed through the doors ρ and p ¹ , while both plate stoves are provided with door openings r ¹ and r for inserting the plates. Both herds α and a ^l are almost level with the hut bottom, while the stoke bottom of the same is about 70 to 80 cm below the hut bottom; the dotted line η η of Fig. 1 indicates this piercing sole with the access ramps. About two platinum herds is the common Blechwärmherd ee ^1, which is the front right through with slider s apertured direct d with the platinum stove a connected while each board stove ce by the Heizkanäie and C ¹ C ¹ f nor from above through the trains and y ¹ , as well as their outlet openings m and m ¹ with the Blechwärmherdtheil e respectively. e ^{1 is} in communication. At the left end of the tin stove are the actual fire gas outlet openings g, which can also be regulated by the slide s ^1; the former open into the main channel h, whereby the fire exhaust gases are directed into the fox i and from there into the chimney. The side heating channels c and c ^l are also set up to regulate the effect of the flame through the slide o ¹ ; the door t is the same allows for permanent use, while the door t ¹ and the removal of very long sheets to the back of the stove. The space k and k ¹ under the plate stoves is used to store the coals.

Der Wärme- und Arbeitsprocefs dieses Ofens ist nun ein ganz anderer, als der der heutigen Flamm- und combinirten Oefen.The heat and work process of this furnace is now completely different from that of today Flame and combined stoves.

Nämlich für gewöhnlich wird nur mit dem Platinenofen α mit dem vorderen rechten Blechwärmherd e gearbeitet bei der Herstellung von Handelsblechen bis 2,50 m Länge; sollenNamely, usually only with the blank furnace α with the front right sheet metal heating hearth e is used in the production of commercial sheets up to 2.50 m in length; should

Claims

however, longer sheets of up to 4, 5 and 6 m are produced, first the blank heating furnace a ^{1 is} put into operation and is also used to heat the sheet metal hearth part c ¹ . This sets the new furnace apart from all other known annealing furnaces in this branch.

The oven heating process is now as follows:
The stove α is covered with the plates to be heated, the flames developed on the grate b strike over the fire bridge into the stove α, thereby not only heating the plates, but also the overlying sheet metal hearth vault (sole) in a very short time, during the Heating flames enter the sheet metal hearth directly from below through the openings d and heat part ee ¹ sufficiently. The warm boards are taken before and after from the oven α and once rolled and then already laid as a sheet metal in the sheet metal stove e, annealed and further rolled, then annealed again in packing in the oven e to the production to the correct length. If the warming is too strong, the slides 5 are made tighter as required; to be further heated from above the Glühblech so open to the slide ο accordingly, and a portion of the hot gases moves through the side heating cf and openings meters from the top of the Blechwärmherd and warms the sheet everywhere ä'ufserst gleichmäfsig without scale formation. If, furthermore, the completely rolled sheets are to be annealed, which makes them soft, as is well known, the slides s are completely closed, the same ο opened accordingly and the heating occurs from the heating flames only from above, instead of through the openings of m. The action of the latter on the sheet metal is a very mild one and, owing to the adjustable position of the slides ο, it is entirely up to you to regulate them.

If, on the other hand, the furnace is to be used for the production of larger metal sheets over 2 m long, then the plate heating stove a ¹ is also put into operation. As a result of the heating of the plate in it, the hearth vault of a ¹ (the sole of ^{the sheet metal base e 1} ) becomes almost red-hot, which means that the rear end of the sheet metal is also heated very intensively from below. The heating flames of the stove a ^l, on the other hand, pull directly through the side heating ducts c ^l c ^l f ^l f ^l and the openings m ¹ m ¹ from above into the sheet-metal heating stove e ^l , mix here with the incoming heating flames of the stove part e and fill the entire sheet-metal heating stove e and e ¹ with their brightly burning flame, whereby a very even heating of the long sheet is made possible in the same. The slides o ¹ (see Fig. 3) also serve to regulate the flame effect for the various industrial heating purposes in sheet metal production.

You are therefore through this double-blank heating furnace with just one overlying sheet-metal heating stove capable of handling not only small, but also large sheets of up to 6 m in length to anneal, warm and in a short time to fall, d. H. to soften by a lot less coal consumption.
