The safe use method of the water cooling system of the foornada dhalinta dhalaalaysa

The water cooling system of the induction melting furnace ensures the quality of the cooling water and regularly checks whether there is scale. If there is scale, it should be cleaned immediately to ensure the cooling effect. The cooling water quality requirements of general industrial frequency furnaces: pH value 6-9, hardness V10mg equivalent/L, total solid content not exceeding 250mg/L, cooling water temperature rise V25°C. The water quality of the cooling water used for the intermediate frequency power supply: pH value 7~8, hardness V1.5mg equivalent/L, suspended solids not exceeding 50mg/L, resistivity> 4000. • cm. The circulating water in the circulating pool should be tested regularly. When the hardness of the circulating water exceeds 2mg equivalent/L, the circulating water in the system should be emptied and replaced. The cooling tower should be drained regularly in exchange for new soft water to prevent clogging of pipes and nozzles, which will affect the cooling effect and the service life of the furnace lining.

The high temperature of the cooling water is generally due to the blockage of foreign matter in the cooling water pipe, and the water flow is reduced. At this time, it is necessary to blow the pipe with compressed air to remove the foreign matter. In addition, the cooling water pipe has scale and needs to be descaled in time. Use SS-103K descaling and cleaning agent. The general dosage is 10kg/t. Increasing the dosage can improve the descaling effect. The soaking method can be used. For soft and thick scale, the effect will be better if the cleaning fluid is continuously circulated with a circulating pump, and then SS-580 high-efficiency corrosion and scale inhibitor (used concentration 100mg/L in normal operation) is added.
