| 摘要 |
The present invention relates to a cooling apparatus for a furnace, comprising a plurality of cooling plates installed and connected along a coolant supply line in order to cool down a furnace wall. The cooling apparatus is able to block flowing of a coolant to a damaged portion by freely changing an inner flow path of the cooling plate by an easier control. The cooling plate comprises: a body formed with a plurality of coolant flow paths to flow the coolant therein; a common flow path formed on the body, and formed with connection ports connected to the respective coolant flow paths and arranged in a distance from each other; a supply path to supply the coolant and a discharge path to discharge the coolant, formed to be connected with the common flow path; and a spool to selectively connect or block the supply path, the discharge path and the respective coolant flow paths by moving along the common flow path. |
