Description
I lB5269 The present invention relates to a door of a coking oven. More particularly, it relates to a coking oven door which includes a metallic door body and a door plug mounted on the door body and constituted of a refractory ceramic material.
Coking oven doors of the above-mentioned general type are ~nown in the art. In a known coking oven door, a sealing member is provided which is connected with a diaphragm and has an edge abutting against a sealing face of a chamber frame under the action of a pressing member. Locking means are provided in the upper and lower regions of the coking oven door and connected with the door body.
The sealing members for sealing metal to metal in the coking ovens are provided in different forms such as flat iron, L-shaped profile, Z-shaped profile and the like. They are mounted on diaphragms. A11 these sealing members are elastic in a greater region and brought into contact by pressing elements such as spring-bias~ed pressing member. However, these sealing members must be adjusted from time to time, in correspondence with the deformation of the door body and/or chamber frame. This i9 attained by subsequent adjustment of the pressing members or mounting members.
It has been shown in practice that the known steps for the above mentioned subsequent adjustment, which are required for providing abutment of the sealing member against the ahamber frame, are not always sufficient. This is true particularly for coking doors having relatively great construction height. The deformations of the door body take place because of various temperature differences, such as, for example, in operation during the coking time, on the one hand, or changes of throughput capacity, on the other hand. In condition of such deformations,

A11 these sealing members are elastic in a greater region and brought into contact by pressing elements such as spring-bias~ed pressing member. However, these sealing members must be adjusted from time to time, in correspondence with the deformation of the door body and/or chamber frame. This i9 attained by subsequent adjustment of the pressing members or mounting members.
It has been shown in practice that the known steps for the above mentioned subsequent adjustment, which are required for providing abutment of the sealing member against the ahamber frame, are not always sufficient. This is true particularly for coking doors having relatively great construction height. The deformations of the door body take place because of various temperature differences, such as, for example, in operation during the coking time, on the one hand, or changes of throughput capacity, on the other hand. In condition of such deformations,
-2-1 ~65269 the known constructions are not always satisfactory in obtaining reliable closure of the chamber, over a long time. Elastic sealing members which are adjustable on the door body and brought into abutment by the pressing elements against the chamber frame deformed under the action of heat, allow leakage directly after the filling coal into the open chamber. This is particularly true after longer operational time when the deformation of the chamber frame or the door body is so great that satisfactory adjustment for maintaining the originally planned and designed abutment line of the edge of the sealing member cannot be pro-vided. In the construction wherein the diaphragm with the seal-ing member is adjustable but in principle is firmly connected with the door body between the adjustments, the working region of the edge of the sealing member and the pressing force change because of the deformations.
Accordingly, it is an object of the present invention to provide a coking oven door which guarantees reliable sealing relative to a chamber frame without time-consuming and labor-consuming adjustment of a sealing member.
In keeping with these objects and with others which will become apparent hereinafter, one feature of the present invention resides, briefly stated, in a coking oven door in which a diaphragm with a sealing member as well as a pressing element are mounted on a door body, a door plug is mounted on the door body with formation of an intermediate chamber therebetween, and a mounting plate of the door plug and a plug holder mounted thereon have contact faces which are kept as small as possible.
Since the door body and the door plug are arranged so as to form the intermediate hollow space therebetween, the temperature which reaches the door body is considerably smaller .
Accordingly, it is an object of the present invention to provide a coking oven door which guarantees reliable sealing relative to a chamber frame without time-consuming and labor-consuming adjustment of a sealing member.

Since the door body and the door plug are arranged so as to form the intermediate hollow space therebetween, the temperature which reaches the door body is considerably smaller .

than it would be in the case of direct contact of the door plug with the door body. This means tha~ variations of the temperature in the door body either do not take place or are insignificant.
This guarantees that the adjusted working region of the edge of the sealing member remains identical to the end of the coking process with higher temperature of the refractory member of the door plug and during subse~uent insertions with lower temperature of the refractory member of the same.
This effect is further improved by the fact that the membrane and the sealing member are not arranged on the door plug as is conventional in the art, but instead are arranged on the relatively colder door body. When these members were arranged on the door plug, each flexure or longitudinal deformation of the door plug results in changes in the distance to the pressing members. In contrast, the mounting of both the diaphragm and the pressing member on the door body results in maintaining this distance constant. Variations on the edge of the sealing member under the action of the temperature in the chamber frame are thereby needed to be taken up only by the pressing members.
Since the contact faces of the mounting place of the door plug and of the plug holder which is mounted on the mounting plate are maintained as small as possible, the heat transition from the heated refractory member to the mounting plate is reduced to a minimum. In such a construction, it can be provided that the mounting plate takes up at the refractory member side and at the opposite side identical temperatures so as to elim-inate deformation because of a temperature differential, which otherwise can lead to mechanical loading of the door body.
Longitudinal deformations of the door plug because of diffusion `5~g~`
of graphite or thermal post expansion can be compensated by suitable mounting members relative to the door body.
The above-described combination of the door plug ar-rangement with the separation of the door body and door plug as well as with the mounting of the diaphragm and the pressing members on the door body, can provide for reliable sealing rela-tive to the chamber frame, in condition of adjustable varied distance in the event of a deformed chamber frame.
In accordance with another feature of the present invention, the door body is provided with a plurality of limiting or stopping members which are distributed over the periphery of the door body and spaced from one another in a circumferential direction. When the coking door is designed in accordance with this feature, the door can be brought by a door servicing machine to its predetermined location relative to the chamber frame and the locking hooks.
The novel features which are considered as character-istic for the invention are set forth in particular in the ap-pended claims. The invention itself, however, both as to its construction and its method of operation, together with addi-tional objects and advantages therefor, will be best understood from the following description of specific embodiments when read in connection with thé accompanying drawings.

The door lock 2 is mounted on the door body 1 by screws 3. The door body 1 is generally constituted of metal. A plur-ality of spacer members 4 are provided between the door body 1 and the door plug 2 so that an intermediate space 5 is formed between the same.
A diaphragm 7 which may be constituted of metal is clamped on the door body 1 by screws 7. The diaphragm 7 is cir-cular and circumferentially closed. A sealing member 8 extends over an outer periphery of the diaphragm 7. The sealing member 8 is a packing strip which is formed here as a flat iron.
The sealing member 8 has an edge or plate which seal-ingly abuts against a sealing ace 9 of a chamber frame 10. A
spring-biased pressing member 11 acts upon the sealing member 8.
The sealing member 11, similarly to the diaphragm 7, is mounted on the door body 1. Finally, a further clrcular metallic dia-phragm 12 is clamped by the screws 6. The metallic diaphragm 12 is U-shaped and limits the intermediate space 5 between the door body and the door plug from outside.
The door plug 2 has a mounting plate 13 and a holding element 14 for holding a refractory member. The holding element 14 is mounted on the mounting plate 13 by screws 15, as can be seen from Figs. 3 and 4. The contact faces of the mounting plate and the holding member 14 are kept to a minimum.
A plurality of adjustable limiting members 16 are further provided. One of _he limiting members is shown in Fig. 1 and identified by reference numeral 16. The limiting members are spaced from one another over the periphery oE the door body 1 and I

serve for correct placing of the door at a predetermined distance from the chamber frame 10.
Door locking means are further provided. The door locking means includes door locking elements identified by reference numberal 13 and arranged in the upper region and in the lower region of the coking oven door, as can be seen from Figs. 1 and 2.
The sealing member formed as a flat iron has advan-tageously a small height, for example, of 35 millimeters. Such a sealing member can effectively abut against the sealing face of the chamber frame in the event of deformation.
It will be understood that each of the elements des-cribed above, or two or more together, may also find a useful application in other types of constructions differing from the types described above.
While the invention has been illustrated and described as embodied iA a door of a coking oven; it i8 no-t intended to be limited to the details shown, since various modifications and structural changes may be made without departing in any way from the ~p1rit of the present invention.
