A coke drum skirt to minimize the stresses experienced by the coke drum and the supporting structure of the coke drum is described. The skirt includes one circumferential horizontal plate attached to the coke drum, and the circumferential horizontal plate is slidingly sandwiched between a lower supporting plate that supports the weight of the drum through the circumferential horizontal plate and an upper retaining plate that prevents the coke drum from tipping or falling over. The upper retaining plate may be embodied as a series of retaining clips that also keep the coke drum centered and prevent rotation of the coke drum. The upper and lower plates are anchored to a concrete support base. The sliding connection of the plates allows the coke drum to thermally expand and contract while reducing stresses and metal fatigue from the typical fixed securing of the coke drum to the support base.

A linked coke drum connection to minimize the stresses experienced by the joint between the coke drum and the supporting structure of the coke drum is described.

The invention provides a method for dismantling a coke oven column and a protection plate. The method is characterized by including the following steps that a, preparation work is done for dismantlingthe coke oven column and the protection plate; b, a coke oven machine, an oven column on the coke side and the protection plate are dismantled at the same time; c, before the coke oven column and theprotection plate are dismantled, the coke oven machine and springs of an upper cross brace and a lower cross brace on the coke side are subjected to pressure relief; d, before the coke oven column and the protection plate are dismantled, the coke oven machine, and a big spring and a big spring baffle on the upper cross brace on the coke side are fixed; e, the protection plate is assembled and a lifting point is set; f, the oven column, a protection plate hoist, the coke oven machine, the oven column on the coke side and the protection plate need to be dismantled and hoisted at the same time.The method for dismantling the coke oven column and the protection plate has the advantages that the design of dismantling steps is reasonable, the operability is high, the demolition project is safeand reliable, the coke oven column and the protection plate can be quickly dismantled, the labor intensity is reduced, the construction period is shortened, the construction cost is saved, the projectcost is reduced and economic benefits are remarkable.

The invention provides an installing method for an oven protecting iron component for a coke oven. The method comprises the following steps: 1) an oven column and a protection board are separately transported into an operation table in the coke oven, the oven column and the protection board are fixed as a whole lifting module by using a special clamping tool, and the oven column is installed in alifting manner by adopting main crane and auxiliary crane structures; 2) a door frame is transported into the operation table, and the door frame is installed in a lifting manner by adopting the maincrane and auxiliary crane structures; and 3) an oven door is transported into the operation table, a special lifting tool is installed for the oven door, the special lifting tool and the oven door arecombined to form an integral lifting module, the module consisting of the oven door and the special lifting tool is placed on the operation table by using a main crane and an auxiliary crane, the auxiliary crane is removed, the top of the oven door is lifted by using a rotating base seat of the special lifting tool as a center to lift the oven door, and the oven door is lifted to the installationposition for installing and fixing. The oven protecting iron component provided by the invention is modularly assembled on the ground, and is installed through integrated lifting in place, so that the installation strength and installation safety risks are reduced, two cranes are cooperated, the moving speed of each module is well controlled, and the installation position can be straightened.

The invention discloses a quick installation method of a coke oven guard plate and an oven column, comprising the following steps: 1) after a coke oven body is built, a temporary fixed mount is respectively arranged on the positions on two sides of an oven top machine, which correspond to the installation positions of a guard plate and an oven column; 2) after the guard plate is hung to the proper position and adjusted, a binding piece connects the upper part of the guard plate with the temporary fixed mount so as to temporarily fix the guard plate; 3) after the guard plate is temporarily fixed, the oven column is hung to the proper position, and then the oven column is adjusted, the binding piece connects the upper part of the oven column with the temporary fixed mount so as to temporarily fix the oven column; 4) the cross-brace of the oven column is installed to formally fix the guard plate and the oven column; and 5) the binding piece and the temporary fixed mount are disassembled.The invention is simple and easy to realize, is easy to operate and master, can be flexibly adjusted according to the conditions, such as manpower, equipment and the like, can centralize the superiorforce of relevant type of work and improves quality and efficiency; the coke oven guard plate and the oven column can be intensively installed so as to reduce lifting machine transit shipment time and save installation time and machinery cost.
