An oven is a device that uses an electric heating wire to heat the object. It is suitable for baking, drying, heat treatment, etc. in the range of 5~300 °C (some 200 °C higher) than room temperature, and the sensitivity is usually ±1 °C. It has many models, but the basic structure is similar. It is generally composed of a box, an electric heating system and an automatic temperature control system. What should be paid attention to when using the oven and the oven and the safety regulations for use 1. Place the oven and the oven, and do not put inflammable and explosive materials around the equipment.
2, pay attention to safe use of electricity, according to the power consumption of the oven to install a sufficient capacity of the power knife problem: this workshop bought an oven, the first is to hold the glue on the top of the transformer baking, respected in the application process center should Pay attention to which details. The oven should be placed indoors dry and to prevent vibration and corrosion from using sufficient power leads and should have a good grounding wire.
3. The oven with the electric contact metal mercury thermometer type thermostat should connect the two wires of the electric contact thermometer to the two terminals on the top of the box, and insert a common metal mercury thermometer into the exhaust valve. (The thermometer in the exhaust valve is used to calibrate the metal mercury thermometer of the electrical contact and observe the actual temperature inside the box.) Open the opening of the exhaust valve. Adjust the electrical contact metal mercury thermometer to the required temperature and tighten the screws on the steel cap. In order to achieve the purpose of constant temperature, but must pay attention to the adjustment, do not screw the indicator iron out of the scale.
4. When all preparations are ready, put the sample into the oven, then connect and turn on the power. The red indicator light indicates that the box has been heated. When the temperature reaches the controlled temperature, the red light is off and the green light is on. Control failure, you must also look after.
5. When placing the sample, it should be noted that the sample should not be placed too tightly on the heat sink. The test piece should not be placed to avoid affecting the flow of hot air. It is prohibited to bake flammable, explosive, volatile and corrosive items.
6. When you need to observe the sample in the office, you can open the outer door and observe through the glass door, but the door should be opened even if it is less open to avoid affecting the constant temperature, especially when working above 200 °C. The glass door may be quenched and broken.
7. There is an air-blasting oven. In the process of heating the constant temperature, the hair dryer must be turned on, otherwise it will affect the uniformity of the office temperature and damage the heating element.
8. The power should be blocked in real time after the work is completed to ensure safety.
9. The inside and outside of the oven should be clean.
10. When applying, the temperature should not exceed the maximum application temperature of the oven.
