How to use medium frequency induction heating furnace for your reference

The usage method of medium frequency induction heating furnace is for your reference. If there are any deficiencies, please correct me!

1. When using the medium frequency induction heating furnace, pay attention to the furnace conditions. Observing the furnace conditions is a kind of protection for the furnace. Measure the furnace bottom every 3 days, and observe the furnace wall every day to ensure the safety of the furnace lining. .

2. Maintain and maintain the medium frequency induction heating furnace, such as purging the coil frequently and cleaning debris on the coil to prevent coil breakdown, thereby avoiding furnace dismantling due to equipment failure and effectively increasing the service life of the crucible.

During use, when the furnace needs to be shut down for a long time due to malfunctions and other reasons, the molten iron in the furnace should be emptied to avoid damage to the furnace lining due to cracking of the furnace lining when the molten iron condenses; when the molten iron cannot be poured out and the molten iron has been Condensation, when it is impossible to judge whether the furnace lining is intact, the furnace should be dismantled for safety reasons.

3. In the medium frequency induction heating furnace, try to avoid high-temperature melting during the melting process. At high temperature, the furnace lining will undergo a crucible reaction with the molten iron, as shown in the following formula: SiO2 2C→Si 2CO. The higher the temperature, the higher the C, and the lower the Si, the corrosion of the furnace lining will intensify, especially in new furnaces. , so when melting, try to avoid high temperatures while ensuring the outlet water temperature. The outlet water temperature is 1490°C ~ 1540°C, but during the induction furnace melting process it is generally controlled at 1490°C ~ 1520°C; it is worth mentioning that the power is turned off after the water is released. Insulate at a lower temperature, and then heat up according to the temperature of the previous bag of water when preparing to discharge water. This can reduce the erosion of the furnace lining by high-temperature molten iron, extend the service life of the furnace lining, and reduce power consumption. It is a good way to increase the age of the furnace and reduce power consumption. method.
