中频炉的冷却水是为了缓解中频炉在工作过程中产生的热量，带动装置和周围温度上升，如果不及时冷却可能会对装置性能和中频电炉的功率产生影响，甚至还会烧坏装置，所以中频炉冷却水的作用十分重要。那么大家清楚中频炉冷却水水温要求是多少吗？
The cooling water of the intermediate frequency furnace is used to alleviate the heat generated during its operation, drive the equipment and surrounding temperature to rise. If not cooled in a timely manner, it may affect the performance of the equipment and the power of the intermediate frequency furnace, and even burn the equipment. Therefore, the role of the intermediate frequency furnace cooling water is very important. So, are you clear about the requirements for the cooling water temperature of the intermediate frequency furnace?
一、中频炉冷却水水温要求
1、 Requirements for cooling water temperature of intermediate frequency furnace
1、水温要求：中频炉冷却水的进水温度要保持在5~30℃，出水温度应控制在30-40℃，出水温度低于55℃。冷却水温度过低会出现结露现象，水温超过55℃则失去冷却能力。为了节约用水，通常采用循环冷却体系。
1. Water temperature requirements: The inlet temperature of the cooling water for the intermediate frequency furnace should be maintained at 5-30 ℃, the outlet temperature should be controlled at 30-40 ℃, and the outlet temperature should be below 55 ℃. If the temperature of the cooling water is too low, condensation will occur, and if the water temperature exceeds 55 ℃, the cooling capacity will be lost. In order to save water, a circulating cooling system is usually used.
2、可控硅变频器参数要求：冷却水压力应稳定地保持在0.15MPa，水质应进行软化处理，硬度小于P8，电阻在20kΩ以上，水中不溶解物小于0.03mg/L，水量8 吨/时，出水管内径大于3英寸。
2. Parameter requirements for controllable silicon frequency converter: The cooling water pressure should be stably maintained at 0.15MPa, the water quality should be softened, the hardness should be less than P8, the resistance should be above 20k Ω, the insoluble substance in water should be less than 0.03mg/L, the water volume should be 8 tons/hour, and the inner diameter of the outlet pipe should be greater than 3 inches.

二、中频炉冷却水水温过高的危害
2、 The Harm of Excessive Cooling Water Temperature in Medium Frequency Furnace
有数据指出，中频炉线圈和冷却水温度升高25℃，其耗电量和电阻比之前增加10.75%，每小时耗电量增加10.8kW?h，占体系总功率的2.7%。负载电流通过供电线圈和水电缆时，线圈和水电缆发热导致温度不断升高，电阻也会增大，电阻增大的同时发热量增幅，又进一步使温度升高，这样供电线路升温和电阻变化形成恶性循环，所以需要通过冷却水对线圈进行降温同时控制冷却水的温度保障持续降温的作用。冷却水过热不仅会影响中频炉功率严重时可能会出现烧坏装置的情况，那么该如何解决？
There is data indicating that an increase of 25 ℃ in the temperature of the coil and cooling water of the intermediate frequency furnace results in an increase of 10.75% in power consumption and resistance compared to before, and an increase of 10.8kW in power consumption per hour? h. Accounting for 2.7% of the total system power. When the load current passes through the power supply coil and water cable, the heating of the coil and water cable causes the temperature to continuously increase, and the resistance will also increase. As the resistance increases, the heat generated will increase, further causing the temperature to rise. This creates a vicious cycle of power supply line heating and resistance changes. Therefore, it is necessary to use cooling water to cool the coil while controlling the temperature of the cooling water to ensure continuous cooling. Overheating of cooling water not only affects the power of the intermediate frequency furnace, but also may cause equipment damage. How can we solve this problem?
