Safety precautions should be observed during the use of tunnel furnaces:

1. When everything is ready for work, place the sample in the oven and connect and turn on the power. The red indicator light indicates that the box has been heated. When the temperature reaches the temperature controlled, the red light goes off and the green light is on and the temperature starts. In order to prevent temperature control failure, must also take care.

2. Put the sample should be noted that the arrangement can not be too dense. Heat sink should not put the test article, so as not to affect the hot air flow up. Do not bake baked flammable, explosive, volatile and corrosive items.

3. When you need to observe the situation in the studio sample, you can open the outer box door, through the glass door observation. But the door to minimize the opening as well, so as not to affect the temperature. Especially when working above 200 ℃, open the door is likely to make the glass door quenching and rupture.

4. A blast oven, which must be opened during heating and constant temperature, otherwise it will affect the uniformity of the temperature of the workplace and damage the heating element.

5. Should be placed in the indoor dry and horizontal, to prevent vibration and corrosion.

6. Pay attention to safe use of electricity, according to the oven power consumption to install a sufficient capacity of the power knife. Select enough power conductors and should have a good grounding wire.

7. Oven with electrical contact mercury thermometer thermostat The two wires of the electrical contact thermometer shall be connected to the two terminals of the box top. Also insert an ordinary mercury thermometer into the exhaust valve (the thermometer in the exhaust valve is used to calibrate the electrical contact mercury thermometer and observe the actual temperature in the box) to open the exhaust valve hole. Adjust the electrical contact mercury thermometer to the required temperature after tightening the screws on the steel cap to achieve the purpose of constant temperature. But must be careful not to adjust the instructions when the iron rotation to the scale outside the scale.

8. When used, do not exceed the maximum temperature of the oven.
