Abstract
Method and apparatus for applying patching or sealing compositions to the interior side walls and roof of a coke oven. In service the refractory of the side walls and roof develops cracks which need to be sealed. According to the invention, a gunning apparatus is mounted on the pusher machine. The head of the pusher ram carries a spray nozzle connected through pipes and a flexible hose with a gun tank mounted on the pusher machine chassis. The patching or sealing composition is applied immediately after coke is pushed from the oven by running the ram through the empty oven without waiting for the oven to cool.
