FIELD: cooling.
SUBSTANCE: invention relates to cooling system of lining of high-temperature metallurgical furnace. System comprises a cooling liquid supply device, a cooled object cooling device communicated with a cooling liquid supply device by means of a cooling liquid supply pipeline, a hydraulic lock tank and a cooling liquid return device, comprising a coolant return pipeline unit and a vacuum pump, wherein the coolant return pipeline unit includes a coolant return pipe, a vacuum line and a siphon pipeline communicated by one channel, vacuum pump is connected to vacuum pipeline, coolant return pipe is communicated with cooling device, siphon pipeline is communicated with hydraulic lock tank, wherein horizontal plane of device for supplying cooling liquid is higher than horizontal plane of hydraulic lock tank.
EFFECT: reduced risk of industrial accident due to spill of cooling liquid.
