Working principle of high temperature chamber furnace:
The thermocouple converts the furnace temperature into a voltage signal and adds it to the microcomputer temperature control regulator. The regulator compares this signal to a program-controlled setting and outputs an adjustable signal. Then use the adjustable signal to control the trigger, and then trigger the voltage regulator to achieve the purpose of adjusting the electric furnace voltage and electric furnace temperature.
Precautions for the operation of high temperature chamber furnaces:
1.Remove the iron filings in the furnace and clean the bottom plate of the furnace to avoid short circuit damage caused by the iron filings falling on the resistance wire.
2. The workpiece of the chamber furnace should not exceed the maximum load of the furnace floor, and the workpiece should be loaded and unloaded under the condition that the power supply is disconnected.
3. Pay attention to check the installation position of the thermocouple. After the thermocouple is inserted into the furnace, it should not touch the workpiece.
4. Determine the reasonable process range according to the drawing requirements of the workpiece. Heat up on time, operate out of the oven, check the temperature of the instrument frequently and calibrate it to prevent misoperation.
5. For the furnace temperature, you can not open the chamber furnace door casually, and check the situation in the furnace should be observed from the furnace door hole.
6. The coolant should be placed in a nearby and convenient position to reduce the cooling of the workpiece after it is out of the oven.
7. The station should be correct when coming out of the oven, and the clamping should be stable to prevent the hot workpiece from harming the human body.
8. After the box furnace is overhauled, it must be baked according to the regulations, and check whether the furnace hall and top insulation powder are filled and whether the grounding is fastened with the furnace shell.
