Claims (2)

ι 2 The invention relates to a coke oven door, which also has no connection between the bemen from a metallic door body part with holding frame base plate and the metallic door body part for one made of refractory rammed earth and iron, rather the ones mentioned in Möreinlage between them manufactured stopper, the iron inserts tel embedded insulating stones are arranged, can consist of a number of individual rods, with 5 the thermal expansion of the individual rods to the door affect the limitation of the plug towards the metallic body. This stretch, which is in the Door body part connected towards the forming base plate will usually not be more than 1 to 2 mm are. full of insulating stones embedded in mortar The fireproof protruding into the furnace chamber was added so that the fireproof door stopper The coke oven door is not only plugged in because of the thermal expansion of the coke oven door exposed to high temperatures, but individual rods can act it is also found when the door is removed for the purpose of emptying. It should also be mentioned that in the case of the Every time the furnace chamber is emptied, a strong coke oven door of the stopper is designed according to the design cooling. With such a load there is no bond with the refractory rammed earth Duration of the formation of cracks in the stopper has practically 15 metallic door body part, stopper and can not be avoided. The consequence of this is that the metallic door body part is different Stopper individual pieces falling out or what can also expand. often happens, the whole stopper tears through there, Γη further training of the invention where the holding frame ends. The destruction of the fire coke oven door can be the iron rods on the base plug but means apart from the effort 20 plate be arranged offset and different for its renewal have a great risk of length. In addition, the operating personnel are expediently protected by falling heavy base plate with the stopper attached to it over fragments. the height of the coke oven door divided several times so that. In order to remedy this inconvenience, it has already been proposed, if it is necessary to replace the stopper with iron inserts, that only the part of the stopper in need of repair should be replaced. So is on a known coke oven door must be. It has been shown, however, that the holding base plate attaches a U-shaped wire mesh, availability of a door stopper formed just below the outer surfaces of the stopper, according to the proposal of the invention, many times over and thus encloses it. If applicable, the known constructions is,
In this case, two nested U-shaped wire meshes can also be provided in the drawing. With these co- illustrated. In this, 1 of the metallic turtle cannot prevent destruction of the fire-proof door body part and 2 of the holding frame for the stopper cannot be prevented. Since the expansion refractory ramming material keeps existing plug 3 of iron and ramming material draws differently. This plug protrudes in the operating state in is, on the contrary, it must be expected that the plug formed by the indicated heating walls 4 will be blown by the iron. Oven chamber. Furthermore, a coke oven door is known in which, as the plug 3 is partially penetrated by straight iron inserts, individual rods are used, which are attached to the iron rods 5, which in the present case are fastened in the base plate. The base plate is arranged here in rows, with the rods rigidly connected to the metal door body part, following rows of different lengths and each bound, and the individual rods extend from opposite the rods of adjacent rows in a fan-like manner at a central point on the base plate are in. The bars are with the base plate 6 verden fireproof door plugs. Because of the rigid welds and splayed at their connection facing away from the base plate of the base plate and the metallic door body ends. The base plate limits the door part, the thermal expansion of the single rods can only 45 plug 3 to its end remote from the oven, ie in the direction of the fireproof door plug, to the metallic door body part I.
which is thus torn apart by the individual rods running in different directions between the base plate 6 and the metal. Door body part 1 are insulation embedded in mortar 7 Finally, a coke oven door with stones 8 is also provided, the compressibility of which is the same as in the Form stones existing door frame known, in the 50 operating state taking place length expansion of the the shaped stones of dovetail-shaped Me-iron rods over the base plate allows. To this tallkkörperern are held, the intervening way is a burst of the plug through the Connection of an insulating layer to the door body fixed iron rods avoided with certainty. Also a are connected. Tearing through the stopper, which has often been along the way up to now It has now been found that an optimal 55 of the dash-dotted line 9 between the through the Durability of the refractory plug reached when beads 10 of the support frame 2 weakened points the individual rods were essentially perpendicular to the base, but this is no longer the case with the new design run plate and between the base plate and possible
the metallic door body part the elongation of the individual rods over the base plate, 60 claims:
Insulating bricks embedded in mortar are arranged. The individual rods of the coke oven according to the invention 1st coke oven door, consisting of a metal door penetrate most of the thickness of the fire-Iischen door body part with holding frame for one solid door stopper and thus give it the required refractory ramming compound and iron inlays lent cohesion. Since no connection of the 65 manufactured stoppers, the iron inserts from Rods consists of one another, here is a bursting of a number of individual rods that exist with Door stopper, as is the case with the known U-shaped one, the limitation of the stopper to the metal against iron deposits will not occur. Since the door body part forming the base plate are connected, characterized in that the individual rods (S) run essentially perpendicular to the base plate (6) and between the base plate and the metal door body part (1) the elongation of the individual rods over the base plate and embedded in mortar (7) insulating stones (8 ) are arranged. . j, 2. Coke oven door according to claim 1, characterized in that that the iron bars (S) are arranged offset on the base plate (6) and have different lengths. 1 sheet of drawings
