Box-type resistance furnace safety technical operation regulations and precautions

Box-type electric furnace (muffle furnace), suitable for laboratory or factory for analysis and measurement research, high temperature burning and metal heat treatment and other work. Transistor constant temperature automatic temperature controller used in conjunction with or in conjunction with the constant temperature controller to control the furnace Internal temperature to work.

Safe technical operation rules of box resistance furnace:

1. Do not exceed the maximum temperature of the resistance furnace during use.

2. Be sure to cut off the power when loading and unloading the sample to prevent electric shock.

3. The opening time of the furnace door should be as short as possible when loading and taking samples to prolong the service life of the electric furnace.

4. Prohibit pouring any liquid into the furnace.

5. Do not put the sample with water and oil into the furnace; do not use the clip with water and oil to take the sample.

6. Wear gloves when handling samples to prevent burns.

7. The sample should be placed in the middle of the furnace, neatly placed, and not placed randomly.

8. Do not touch the electric furnace and surrounding samples casually.

9. After use, power and water should be cut off.

10. Do not operate the resistance furnace without the permission of the management personnel, and operate in strict accordance with the operating procedures of the equipment.

Precautions for the use of box resistance furnace

1. Place the automatic temperature controller in a stable place, not too close to the electric furnace, so as to avoid the heat of the electric furnace affecting the electronic components, remove the short-circuit wire, and then connect the power cord to the electric stove with the power cord, and then connect to the power cord AC 220V, and effectively connect the electric furnace controller.

2. Connect the thermocouple to the temperature device with a wire, pay attention to Â± pole is not wrong, after installation is complete, check if there is any error.

3. Turn the temperature regulator to the required temperature, connect the power supply of the control box "input", turn on the power switch, then the green light turns to red light and start working.

4. When the electric furnace is used for the first time or after long-term use, it must be dried in the oven:

Oven temperature and time:

200 â„ƒ for 1 hour

400 ï½ž 500 â„ƒ for 1 hour

600 ï½ž 800 â„ƒ for 1 hour

Five, matters needing attention

During installation, all power distribution equipment and instruments have been checked and adjusted, and the electric furnace and voltage are normal, and there is good contact. The maximum temperature should not exceed the limit temperature of the series product configuration. The power in the furnace must be cut off to ensure safety. , The electric furnace should be placed in a dry place to prevent moisture, use electric leakage and cause cracking after heating of refractory materials. If the automatic temperature controller needs to be exchanged, the console short circuit wire should be connected to avoid damage to the vibration meter.
