On-line continuous stainless steel tube induction heating annealing furnace has many technical applications in machinery manufacturing, petroleum, chemical and other fields due to its characteristics of fast heating speed, high production efficiency, energy saving and environmental protection. However, in industrial production, the pressure of induction heating equipment is high and the temperature is high, which is more prone to equipment failure.
Let Hangao Tech (SEKO Machinery) introduce daily operation and maintenance below:
1. Boot up
① Open the cooling water gate valve and start the water pump.
②Turn on the control power supply and check whether the "power output adjustment" button is in the "0" position.
③Press the "main circuit open" button, press the "reset" button, and the DC voltmeter is negative voltage at this time.
④Slowly turn the "power output adjustment" knob clockwise, and if you hear a beep at the intermediate frequency, it means the cranking is successful.
2. Shut down
① Slowly turn the "power output adjustment" knob to the "0" position, and the DC voltage indicator is negative at this time.
②Turn the "Reset" button until the reset button pops up, and the DC voltage indicator is zero at this time.
③Press the "main circuit off" button
④Turn off the control power supply, such as temporary shutdown, do not turn off the control power supply.
⑤ About 40~60 minutes after shutting down, the furnace cools down to below 55 degrees, and then turn off the cooling water.
3. Maintenance
1) Before each start-up, check whether there is water leakage in the water-cooling system, whether the cooling water outlet is smooth, and whether the indicators of each instrument are normal.
2) Frequently check whether there is abnormal temperature rise, abnormal noise, etc. during operation.
3) After each production is completed, all the remaining billets in the furnace must be pushed out, and the iron oxide chips left in the furnace must be blown out with compressed air.
4) Brutal operation is prohibited. When replacing the quartz tube or graphite sleeve, the operation should be as gentle as possible to avoid impact.
5) When using the stainless steel tube annealing furnace, the operator is not allowed to leave the post privately, and should always pay attention to whether the working conditions in the furnace are normal.
6) When replacing accessories or re-introducing the tube, the power supply of the heating element must be cut off to ensure the safety of the operator.
7) The oxides in the furnace should be arranged frequently, at least once a week. Compressed air can be blown under the furnace floor.
8) Precautions: The motor of the electric furnace should be checked regularly and lubricated to pay attention to the safety of operation. It is necessary to check frequently and add lubricating oil to the drive shaft sleeve to prevent the shaft sleeve from being damaged due to lack of oil.
9) Regularly check the operating status of the heating element, appearance and thermocouple to prevent incorrect temperature measurement due to appearance and thermocouple errors.
