Installation and commissioning of water cooling system for metal melting furnace
The water-cooling system is an important part of the entire furnace installation. The correctness of its installation and debugging will affect the normal operation of the furnace in the future. Therefore, before installation and commissioning, first check whether the various pipes, hoses and corresponding joint sizes in the system meet the design requirements. It is best to use seamless steel pipes for the water inlet pipe. If ordinary welded steel pipes are used, the inner wall of the pipe should be pickled before assembly to remove rust and oil stains. The joints in the pipeline that do not need to be disassembled can be connected by welding, and the welding seam is required to be tight, and there should be no leakage during pressure test. The detachable part of the joint in the pipeline should be structured to prevent water leakage and facilitate maintenance. After the water cooling system is installed, a water pressure test is required. The method is that the water pressure reaches the highest value of working pressure, and the well protects
After ten minutes, there is no leakage at all welds and joints. Then conduct water and drain tests to observe whether the flow rates of the sensors, water-cooled cables, and other cooling water channels are consistent, and make appropriate adjustments to make them meet the requirements. The backup water source and its switching system should be completed before the first test furnace.
