Abstract
Abstract A coke oven door construction for closing and opening in a coke oven furnace comprising a brick supporter for carrying bricks in the coke oven furnace opening which is subject to high temperatures in the coke oven furnace and thermal expansion, and a door body connected to the brick suppor-ter and having a locking mechanism for retaining the brick supporter in the coke oven furnace opening. The door body and brick supporter are elongated and rigidly connected to each other by at least one connecting pin at one elevation along the door body and brick supporter. The door body and brick supporter are also connected to each other by a plurality of sliding connec-tions along the length of the door body and brick supporter whereby longitu-dinal thermal expansion of the brick supporter is not transmitted to the door body so that the door body and brick supporter is not warped by such thermal expansion.
Description
The present invention relates in general to a coke oven furnace construction, and more particularly to a coke oven door used to seal the open-ing of a coke oven furnace.
Prior to the present invention the door body of a coke oven door that includes a locking mechanism and which is situai:ed outside and in front of a coke oven furnace opening, and the brick supporter which carries bricks that are directly subject to extremely high temperatures in the coke oven furnace opening have been integrally constructed and secured directly to each other by means of bolts or the like.
There are generated great differences in temperature between the brick supporter, which is subject to such extremely high temperatures as 800C to 1100C, and the door body, so that the door body tends to bend or distort outwardly due to heat expansion.
Lt is a disadvantage of this construction that this phenomenon often prevents the opening of the coke oven furnace from being Eirmly sealed by means of the door. Crevices are produced between the door and the opening of the coke oven furnace so that gas or tar are leaked, resulting in air pollution. Another disadvantage of this construction is that to prevent these leaks it is often necessary to adjust knife edges provided on the door body which seal the body to the coke oven furnace.
Summary of the Invention According to the present invention there is provided a coke oven door construction for closing an opening in a coke oven furnace comprising a vertically elongated brick supporter for carrying a brick block in the coke oven furnace opening which is exposed to high temperature within the coke oven furnace, a door body spaced from the brick supporter and connected thereto for carrying the brick supporter in the coke oven furnace opening, said brick supporter being subject to vertical thermal expansion of varying 1~,, ' ' ' .

degree along its vertical length due to the high temperature in the coke oven furnace with highe} expansion at an upper portion than at a lower portion of said brick supporter, at least one connecting pin rigidly connect-ed between said brick supporter and said door body at one vertical Location on said door body, a plurality of spaced sliding mechanisms connected between said brick supporter and said door body for providing a sliding engagement between said brick supporter and said door body, whereby vertical thermal expansion of said brick supporter is not transmitted to said door body so that said brick supporter and door body are not warped and distorted, said at least one connecting pin being connected at a vertical position above the central vertical position of said door body and brick supporter so that the thermal expansion of an upper portion of said brick supporter above said at least one connecting pin is equal to the thermal expansion of the lower portion of said brick supporter below said connecting pin, a sea:Ling plate connected around the periphery of said brick supporter, and a knife edge connected around the periphery of said sealing plate bearing against a periphery of the coke oven furnace opening to maintain a seal between said brick supporter and the coke oven furnace opening.
Such a construction makes it possible for the bricks and supporters which are subject to extremely high temperatures not to directly affect the door body though they themselves extend, so that the door body will not be distorted or bent.
A conventional door for a coke oven furnace has been made in general of such large-sized and thick material so that it has a high stiffness in order to prevent the door body from being distorted due to heat expansion~ ;
and to increase bearing stresses. The total weight and size of the door thus often becomes increased to an undesirable extent so that the opening, closing, attaching and detaching operations for the door become difficult. Large-sized --2~
.. . . ..
, . : ~ ~ , door lifters are also needed, due to the great size. According to the present invention, it is not necessary to strengthen the door body, unlike in conventional ones, so that a light-weight door can be obtained, which enables the attaching and detaching operations to be more easily carried out.
The novel door for a coke oven furnace is not distorted and does not reduce the sealing effect with the opening of a coke oven furnace, and a reduced requirement for adjusting operations of knife edges which are pro-vided. The door is easily attachable and detachable, and is light-weight and simple in design, rugged in construction and economical to manufacture.
For an understanding of the principles of the invention, re~erence is made to the following description of typical embodiments thereof as illus-trated in the accompanying drawings.
