How to use the oven correctly and points of attention

Dec 10, 2020

Electric heating tubes, especially finned electric heating tubes, are very common to be used in ovens, so today I will tell you the correct use of ovens and the points of attention for customers' reference only.


  The oven is a device that uses the heating wire barrier to heat the object to dry. It is suitable for baking, frying, heat treatment, etc. in the range of 5~300℃ higher than room temperature (200℃ higher in some cases), and the sensitivity is usually ±1℃. It has many models, but the basic structure is similar, generally composed of three parts: cabinet, electric heating system, and automatic temperature control system. It should pay attention to the use of ovens and ovens and use safety regulations


   1. Place ovens and ovens, and no flammable and explosive materials can be placed around the equipment.


   2. For ovens with electrical contact metal mercury thermometer thermostats, the two wires of the electrical contact thermometer should be separately connected to the two terminals on the top of the box, and an ordinary metal mercury thermometer should be inserted into the exhaust valve. (The thermometer in the exhaust valve is used to calibrate the electric contact metal mercury thermometer and observe the actual temperature in the box) Open the exhaust valve hole to adjust the electric contact metal mercury thermometer to the desired temperature and tighten the screw on the steel cap, In order to achieve the purpose of constant temperature, but you must pay attention not to turn the indicator iron out of the scale when adjusting.


   3. Pay attention to the safe use of electricity, and install a power switch with sufficient capacity according to the power consumption of the oven. Problem: I bought an oven in this section of the workshop. The first thing to do is to bake the glue on the transformer. Pay attention to the details. The oven should be placed indoors in a dry and adequate place to prevent vibration and corrosion. Choose enough power wires and have a good grounding wire.


   4. When placing the test product, pay attention to the placement of the test product not too densely on the heat sink to avoid affecting the upward flow of hot air. It is prohibited to bake flammable, explosive, volatile, and corrosive items.


   5. When all the preparations are ready, put the test product into the oven, and then connect and turn on the power. The red indicator light indicates that the oven has been heated. When the temperature reaches the controlled temperature, the red light is off and the green light is on. The constant temperature is started to prevent temperature. If the control fails, care must be taken.


   6. When you need to observe the sample situation in the office, you can open the door of the outer door and observe through the glass door, but it is advisable to open the doorless, to avoid affecting the constant temperature, especially when the working temperature is above 200℃, open the door It may cause the glass door to suddenly cool and break.


   7. In a blast oven, the hairdryer must be turned on during the healing process at a constant temperature, otherwise, it will affect the uniformity of the office temperature and damage the heating elements.


   8. After the work is completed, the power supply should be blocked in real-time to ensure safety.


   9. Keep the inside and outside of the oven clean.


   10. When applying, the temperature should not exceed the operating temperature of the oven.
