The operation of high-temperature electric furnaces is actually quite simple, but there are many details to pay attention to during use. While ensuring safety, it's also important to enhance heating efficiency. Today, the editor at StarDing is here to introduce the usage methods and precautions for high-temperature electric furnaces. Let's take a look together!
　　

I. High-Temperature Furnace Operation Procedure

　　
Before using the high-temperature furnace, clean the interior of the furnace chamber first, place the items to be burned inside, and then close the furnace door.
　　
2. Upon powering on the main power, the control box's temperature regulator indicates the furnace temperature, signifying normal operation.
　　
Adjust the temperature control knob to the desired temperature.
　　
Press the green button. The heater will start when the contactor circuit inside the controller is energized, at which point the red indicator light will illuminate.
　　
5. During the heating process, be sure to observe the thermometer. Adjust the temperature control knob to turn on the green indicator light once the desired temperature is reached. At this point, the indicator light will alternate between green and red.
　　
Upon completion of the task, press the red button to cut off all power inside the furnace, and then pull down the circuit breaker.

Section 2: Precautions for Using High-Temperature Furnaces

　　
1. Apart from conducting experiments, do not linger in the high-temperature tube area during other times.
　　
The electric furnace must be properly grounded to ensure safety and reliability.
　　
At the end of the experiment, if further use is not required, the special gas should be turned off, maintain a flow of N2, keep the furnace tube at standby temperature, and check all power sources to ensure they are fully turned off.
　　
4. If the test specimen has an excessive amount of water or oil, it should be degreased and dried before being placed in the furnace.
　　
5. When handling hydrofluoric acid, wear gloves. In case of accidental contact, rinse immediately with water, then rub the affected area with calcium gluconate mixed with 2% water.'。
　　
6. Do not exceed the rated temperature when using the high-temperature furnace to prevent damage to the electrical heating elements and refractory materials.
　　
Use quartz glass products with caution to avoid severe cuts from breakage.
　　
Wear a mask and take appropriate protective measures to avoid inhaling various gases emitted from the furnace or treatment tank.
　　
Potassium cyanide should not be stored with acids, as mixing the two can produce harmful gases.
　　
10. Prevent filter paper, broken crystals, and other debris from falling into the bottom drain hole of the cleaning tank. Otherwise, poor drainage may cause water stains on the floor.
　　
11. At the front end of the long and short push rods, keep them oriented upwards when not in use to prevent contamination.
　　
When the wafer is entering or exiting the furnace, the holder that receives the boat should not touch the furnace tube mouth to prevent contamination of the tube.
　　
The above covers all the details on the operation and precautions for high-temperature furnaces. By following the correct procedure and paying attention to the operational details, you can ensure the smooth progress of the experiment and extend the lifespan of the high-temperature furnace.
