The coke oven protection plate is used to compress the door-shaped hanger of the coke oven protection plate. It consists of a hanger frame that plays a role of hanging and climbing, and a clamping frame that is welded to the upper, middle and lower parts of the hanger frame. The coke oven protection plate is composed of three door-type cards that transmit force. Among them: there is a lifting ring on the top of the hanger frame; each door-type card is equipped with two legs that are in contact with the coke oven protection plate, and the legs are welded to the third On the channel steel, the third channel steel is welded on the hanger frame. When used to compress the protective plate of the coke oven, the installation quality of the protective plate can be improved, so that the gap between the protective plate and the wall of the carbonization chamber is at least 5 to 10 mm smaller in the cold state than the method of pressing the protective plate with the furnace column. This ensures the excellent sealing performance and heat preservation performance of the protective plate on the coke oven head.

Application of coke oven protection plates: Temporary fixing frames are installed at the corresponding installation positions of the protection plates and oven columns on both sides of the coke on the top of the oven; after the protection plates are hoisted into place and adjusted, use lashings to secure the upper part of the protection plates to the oven column. The temporary fixing frame is connected to temporarily fix the protective plate.

Steps for installing the protective board:
1. After the coke oven body is built, temporary fixing frames are installed at the corresponding installation positions of the protective plates and furnace columns on both sides of the coke on the top of the furnace;
2. After hoisting and adjusting the protective board in place, use lashings to connect its upper part to the temporary fixing frame to temporarily fix it;
3. After temporary fixation, hoist the furnace column. After lifting the furnace column and adjusting it, use lashings to connect the upper part of the furnace column to the temporary fixing frame to temporarily fix the furnace column;
4. Install the horizontal braces of the furnace column and formally fix the protective plate and furnace column;
5. Remove the lashings and temporary fixing frames.
The protective board can be flexibly adjusted according to manpower, equipment, etc.; it can concentrate the advantages of relevant work types to improve efficiency; it can be installed centrally to reduce the transfer time of hoisting machinery, thereby saving installation time and machinery costs.
