MORTAR MANUFACTURING APPARATUS FOR SEALING COKE OVEN

The present invention relates to a device for manufacturing mortar for sealing a coke oven, wherein the device manufactures mortar for sealing the gap between the entrance frame of the coke oven and a lid. The device for manufacturing mortar for sealing a coke oven includes a mortar tank which stores mortar, a water tank which stores water, a mixing tank which receives mortar and water from the mortar tank and the water tank and produces a mortar mixture by mixing the mortar and water, and a supply unit which is connected to the mixing tank and supplies the mortar mixture to the gap between the entrance frame of the coke oven and the lid. The device for manufacturing mortar for sealing a coke oven prevents the mortar mixture from being cured by separately storing the mortar and water.
