Maintenance and servicing of medium-frequency furnaces are very important.

Mar 27,2021


   Medium-frequency furnace Every week or every half month, the equipment needs to be shut down for inspection to check all its performance parameters, enabling you to stay promptly informed about the equipment’s condition. Below are the inspections that should be carried out weekly or every half month. Proper maintenance practices can effectively extend the equipment’s service life—let’s explore them together.

   Medium-frequency furnace Before starting up each day, we need to confirm that the system’s power supply, water pumps, and furnace water pumps are all turned on. The water pressure should be between 1.5 and 1.7 kilograms within the power cabinet, and between 1.5 and 2 kilograms in the furnace itself. To ensure optimal operation of the medium-frequency furnace, enterprises must daily use a temperature-measuring gun to monitor the temperatures of the thyristors, the resistor-capacitor protection resistors, and the ambient operating temperature of the equalizing resistors. The temperature-measuring process is divided into three main stages: The first measurement is taken approximately 5 to 10 minutes after the furnace has been started and is running at about one-third of its rated power—this is done when the molten steel is just beginning to fill the furnace, ensuring safe operation. The second measurement is taken again when the furnace is nearly full of molten steel. The third and final measurement is performed at the end of the melting process. Of course, all three measurements must be recorded so that any issues can be promptly identified and addressed. Before starting the medium-frequency furnace, the water pump should be activated 10 minutes in advance to check for any leaks or seepage. If any problems are detected, they must be dealt with immediately to prevent them from escalating into serious issues. If operators notice that the resistor in the rectifier’s resistor-capacitor protection circuit shows significant temperature changes and behaves differently from other resistors, they should immediately investigate the cause—such as whether the capacitor has become open-circuited or whether the resistor network has been damaged. Typically, this will result in an obvious buzzing sound and slight vibration when the furnace is first switched on. If the medium-frequency furnace detects abnormal behavior in the thyristor’s temperature, operators should immediately investigate all possible causes—such as whether a water pipe has kinked, leading to insufficient water flow and overheating, or whether there is dirt buildup inside the thyristor’s housing that’s causing blockage.

  These issues are in use. Medium-frequency furnace Here are some key points that you need to keep in mind both before and after use. The various processes involved during the operation of the furnace are also crucial to its lifespan. Improper handling or operation can significantly shorten the service life of the medium-frequency furnace, so we must pay close attention.
