In winter, the temperature is generally very low, especially in the north of my country. Under the conditions of low temperature or even severe cold, the use of high-frequency, super-audio and intermediate-frequency furnace equipment requires more attention than usual operation, and attention should be paid to relevant antifreeze. measures to ensure the normal operation of the equipment. So, what are the specific antifreeze measures for high-frequency and intermediate-frequency furnaces in winter? The editor of Ruio has made a detailed summary for everyone, let's take a look at it together.

1. Antifreeze measures for high-frequency, super-audio and intermediate-frequency furnaces before operation in winter

In winter, the equipment can be placed in a warmer place with an intermediate frequency furnace. Before opening the equipment, check whether there is ice formation inside the intermediate frequency furnace and cooling, and start the equipment under the condition that the cooling water is unblocked.

1. Antifreeze measures for circulating water channels

       If the production of high-frequency, super-audio, and intermediate-frequency furnaces is not continuous, it is recommended to add antifreeze to the closed water tank of the cooling tower to ensure that the entire circulating pipeline is filled with antifreeze, to ensure that the circulating pipeline does not freeze and crack, and the purity of antifreeze is more than 99%. Ethylene glycol, this antifreeze does not corrode the cooling pipes, nor does it volatilize itself. The ratio of antifreeze and circulating water needs to be selected according to the site.

2. Cooler antifreeze measures

        First of all, when installing the intermediate frequency electric furnace cooling tower, the cooler should be inclined in terms of anti-freezing in winter, so that when the cooling tower is shut down in winter, the cooling water in the cooling tower cooler coil can be drained completely, thereby preventing the cooler. The coil is frozen and cracked due to low temperature. Below zero temperature, if the cooling tower stops running, use high-pressure gas to blow out the residual water in the cooling tower through the water inlet to ensure that the cooler coil will not be frozen.

3. Antifreeze measures for high-frequency, super-audio and intermediate-frequency furnaces after operation in winter

        After use, the water in the high-frequency, super-audio, and intermediate-frequency furnace equipment should be blown clean with an air compressor in time; the water pump should be powered on for 24 hours to ensure that the cooling water in the equipment has been flowing to prevent freezing. Antifreeze can also be added to the intermediate frequency furnace to delay the freezing of the equipment.

        According to the ambient temperature of the place of use, according to the performance parameters of the antifreeze, prepare the antifreeze suitable for the local meteorological characteristics. The freezing point of antifreeze generally needs to be selected to be 10 °C lower than the winter temperature of the residence. The specific amount of antifreeze can be added according to the actual local temperature after consulting the antifreeze provider. The water in the circulating water tank does not need to be too much, as long as it can be circulated, so as to reduce the use of antifreeze. Regular maintenance should pay attention to checking the amount of antifreeze, and if it is found to be insufficient, it should be replenished with antifreeze of the same brand name in time. The antifreeze should be replaced according to the date required by the manufacturer. Generally speaking, the antifreeze should be replaced every two years.

As long as the antifreeze measures for the intermediate frequency furnace in winter are done according to the above contents, the normal operation of the equipment under low temperature conditions can be ensured as much as possible, the equipment can be maintained well, and its service life can be effectively extended. Wenzhou Rui'ao Technology Factory produces and sells high-frequency, super-audio and medium-frequency electric furnaces. The equipment has the advantages of energy saving and environmental protection, convenient operation, good heating and heat permeability, and uniform temperature.
