Heat-insulating method used during hot maintenance of coke oven carbonization room

Abstract

The invention discloses a heat-insulating method used during hot maintenance of a coke oven carbonization room. The heat-insulating method comprises the following steps: 1) laying the whole volume of ceramic fiber felt onto a waved framework of a heat-insulating protective shield used during hot maintenance of the coke oven carbonization room, and tying wave peaks of the waved structure by using ceramic fiber ropes 4, so that a ceramic fiber felt 3 is segmentally stressed, wherein the outer surface of the heat-insulating protective shield used during the hot maintenance of the coke oven carbonization room is coated with a heat-insulating material; 2) after tying completion of the ceramic fiber ropes, transporting the heat-insulating protective shield used during hot maintenance of the coke oven carbonization room to a maintenance site by using manpower or a movable lifting platform; 3) after removing a carbonization chamber oven door required to be maintained, aligning the heat-insulating protective shield used during hot maintenance of the coke oven carbonization room to the a carbonization room, and pushing forward till a position needs to be insulated. In the heat-insulating method, the self-made heat-insulating protective shield used during the hot maintenance of the coke oven carbonization room is used, and during using, the heat-insulating protective shield used during the hot maintenance of the coke oven carbonization room can rapidly insulate high heat of the carbonization chamber, so that the maintenance cycle is shortened; the protective shield can be used for several times in a turnover manner, so that the maintenance cost is lowered.

Description

technical field [0001] The invention relates to the construction technology of industrial furnaces, in particular to a thermal repair and heat insulation method for a coke oven carbonization chamber. Background technique [0002] In the actual production process of the coke oven, due to the uneven expansion of the refractory material in the furnace body, the air flow erosion and high-temperature combustion during the production process, gaps appear in some brick joints and expansion joints, and even bricks break. In order not to affect production, it is necessary to repair or replace the damaged wall of the carbonization chamber in a hot environment. In addition, the long-term mechanical collision between the furnace door and the furnace door frame caused the failure of the disc spring for pressing the furnace door frame, causing smoke and fire (mainly at the hook bolts), and the hook bolts and disc springs of the furnace door frame must be replaced. During the maintenance ...
