Description

Wynalazek niniejszy dotyczy komory pieca do topienia metalu, której dno i ewentualnie takze sciany utworzone sa z rur przez które przeplywa woda.W komorach znanych pieców w celu wykona¬ nia otworów do spuszczania zuzli, trzeba rury sciany komory odpowiednio wygiac i zastosowac oddzielne chlodzenie typu otworów czesto za pomoca oddzielnego obwodu chlodzacego. Ponad¬ to nalezalo zastosowac równiez specjalne srodki do kierowania strumienia wyrzucanych zuzli.Dotychczas znane komory pieców do topienia metalu posiadaly skomplikowana konstrukcje i sa trudne w prowadzeniu.Na rysunku przedstawiono komore wedlug wynalazku, przy czym fig. 1 przedstawia sche¬ matycznie widok boczny komory do topienia me¬ talu, fig. 2 ^- przekrój poziomy wzdluz linii A-B na fig. 1, fig. 3 — przekrój poprzeczny wzdluz linii C — D na fig. 2, fig. 4 — przekrój poprzeczny wzdluz linii E — F na fig. 2, a fig. 5 — przekrój wzdluz linii G — H na fig. 2.Jak wynika z fig. 1 zarówno sciany jak i dno komory do topienia metalu wykonane sa z dwóch zespolów rur kotlowych, krzyzujacych sie w miejscu 5.Rury te moga byc oczywiscie ulozone na pew¬ nym odcinku dna obok siebie w kierunkach przeciwnych. W dnie komory albo pod nim znaj¬ duja sie dwa zbiorniki 3, 4 do wody chlodzacej, przy czym w miejscach zamkniecia komory, z wyjatkiem otworów do spuszczania zuzli i do odprowadzania gazów spalinowych, wyloty le¬ wych rur 1 sa doprowadzone do prawego zbior¬ nika 3, a wyloty prawych rur 2 do lewego zbior¬ nika 4. W miejscach otworów do odprowadzania gazów spalinowych, rozmieszczonych np. w pla¬ szczyznie E — F, wyloty wszystkich rur sa do¬ prowadzone do prawego zbiornika 3 (fig. 4). Ru¬ ry 2 tworza wiec rodzaj rusztu, poprzez którygazy spalinowe przeplywaja do przestrzeni chlo¬ dzonej.W miejscu otworu 6 do spuszczania zuzli (fig. 5), wyloty lewych rur 1 doprowadzone sa do lewego zbiornika 4, a wyloty prawych rur 2 do prawego zbiornika 3, przy czym rury te nie krzyzuja sie wzajemnie.W ten sposób uzyskuje sie dogodne rozwiaza¬ nie konstrukcyjne otworów do spuszczania zuzli, które zarazem sa dobrze chlodzone za pomoca tego samego ukladu chlodzacego. PLThe present invention relates to a chamber of a metal melting furnace, the bottom and possibly also walls of which are formed by pipes through which water flows. In the chambers of known furnaces, in order to make holes for draining the slags, the tubes of the chamber walls must be bent appropriately and separate cooling of the type of holes must be applied. often with a separate cooling circuit. Moreover, special means had to be used to direct the stream of ejected slags. The hitherto known chambers of metal melting furnaces had a complicated structure and are difficult to operate. The figure shows the chamber according to the invention, with Fig. 1 showing a schematic side view of the chamber for by melting metal, Fig. 2, Fig. 2 - horizontal section along line AB in Fig. 1, Fig. 3 - cross section along line C-D in Fig. 2, Fig. 4 - cross section along line E - F in Fig. 2, and fig. 5 - a section along the line G - H in fig. 2. As can be seen from fig. 1, both the walls and the bottom of the metal melting chamber are made of two sets of boiler tubes, crossing at 5. be of course placed on a certain section of the bottom next to each other in opposite directions. In the bottom of the chamber or below it there are two tanks 3, 4 for cooling water, whereby in the places where the chamber is closed, except for the drainage and exhaust gas discharge openings, the outlets of the left pipes 1 are led to the right tank. 3, and the outlets of the right-hand pipes 2 to the left-hand tank 4. At the locations of the exhaust gas discharge openings, for example located in the E-F plane, the outlets of all the pipes are connected to the right-hand tank 3 (FIG. 4). . The pipes 2 thus form a kind of a grate through which the exhaust gases flow into the cooled space. At the place of the opening 6 for draining the sluice (Fig. 5), the outlets of the left pipes 1 are led to the left tank 4, and the outlets of the right pipes 2 to the right tank 3, the pipes not crossing each other. In this way, a convenient design of the drainage openings is obtained, which at the same time is well cooled by the same cooling system. PL

Claims

Claims 1. A chamber of a metal melting furnace made of water-cooled pipes, characterized in that the pipes, forming its bottom and possibly walls, are two or more separate units (1, 2), crossing each other and passing next to each other. each other in opposite directions, except where there is an opening for the discharge of the slug and possibly for the discharge of exhaust gases.

2. The chamber according to claim A method according to claim 1, characterized in that it has separate reservoirs (3, 4), preferably located below its bottom, for draining cooling water from the pipe units (1, 2).

3. The chamber according to claim A method as claimed in claim 1, 2, characterized in that the tanks (3, 4) are spaced apart from each other so that a slag drainage hole and possibly a flue gas discharge hole can be made between them.

4. The chamber according to claims 1 - 3, characterized in that the outlets of the pipes of the set (1) of the left half of the bottom, with the exception of the places where openings for drainage of the sluice are located, are placed in the tank (3), and the outlets of the pipes of the set (2) of the right half of the bottom the bottoms are placed in the left tank (4), while in the place of the chamber where the drain hole is located, the outlets of these pipes are directed opposite.

5. Chamber according to claims Characterized by the fact that in the place of the chamber where the flue gas discharge openings are located, the outlets of the pipes forming the bottom and possibly the walls of the chamber are directed to the tank on the side of the chamber where the discharge openings are arranged exhaust gases.
