How to distinguish between muffle furnace common type and programmable type

How to distinguish between the common type and the programmable type of muffle furnace, this is a headache for many customers. Below, Ronaldinho introduces you to a simple and easy way to separate:

First, we must know what kind of difference and characteristics between programmable and ordinary muffle furnace

The difference between programmable muffle furnace and ordinary muffle furnace

The programmable box type resistance furnace muffle furnace computer control part combines the advantages of other program controllers at home and abroad. It can be multi-band programming, and can set the temperature/constant temperature time arbitrarily->temperature/constant temperature time, up to 30 bands. The unique power output percentage and PID self-aligning function completely solve all the inadequacies of the original high temperature furnace overheating and the inability to control the heating rate. The memory-free special meter for multi-band programming solves the inconvenience caused by forgetting to delete the data of the previous operation during operation. The unique HL function fundamentally solves the problem that the electric furnace reading temperature and the actual temperature are inconsistent for several decades (especially the single-tube double-tube fixed carbon furnace and various electric thermocouples installed outside the furnace tube, It shows that the difference between the temperature and the actual temperature inside the tube is very large).

The box type resistance furnace muffle furnace can also perform low temperature experiments. For example, the 1000-degree muffle furnace is generally used in the range of 800-950 degrees, and it is not possible to perform experiments of about 500 degrees. However, the programmable muffle furnace can perform work experiments with an accuracy of 1 degree.

Second, how to choose the muffle furnace

Programmable muffle furnace and common muffle furnace selection requirements

1. If your experiment only needs to be tested at high temperature and the requirements of the experiment are not high, just choose the ordinary muffle furnace.

2. If you want to experiment at 300-500 degrees, it is recommended to use programmable.

1. First check if the electric furnace complete system is in good condition. Read the instructions and the certificate is complete, read the instructions carefully.

2. Place the electric stove horizontally on the workbench and connect the power cord to the power supply. Pay attention to the wiring markings of the wires when connecting.

3. The furnace shell should have a reliable protective grounding to ensure safe use.

4. When the electric furnace is used for the first time or for a long time, it must be dried by the oven. Oven method: set the temperature at 200 ° C, work for 4 hours (slightly open the furnace door, let go of moisture). Set the temperature to 600 ° C, work for 4 hours, after the oven is completed, the electric furnace can be put into normal use.

1. During the operation of the electric furnace, the temperature inside the furnace is strictly prohibited to exceed 1000 °C. In order to prolong the service life, the long-term working temperature should be 50 °C lower than the rated temperature.

2. The number of times the furnace door is opened should be reduced during the work to avoid the temperature in the furnace being quenched and hot, and the furnace is protected.

3. The furnace door should be lightly opened and lightly closed. The workpiece should be handled gently and gently to avoid damage to the furnace mouth and furnace. When handling the heated workpiece, the power should be cut off to ensure personal safety.

4. When the thermocouple or temperature control instrument is damaged, when it needs to be replaced, it should be ensured that the thermocouple is consistent with the temperature control instrument. Otherwise, the furnace temperature will be inconsistent with the temperature displayed by the temperature control instrument. In severe cases, the electric furnace will be burned. .

5. It is forbidden to directly inject liquid into the furnace, and often clean the iron filings and oxide scale in the furnace to keep the furnace clean.

6. The electric furnace shall not be placed in an environment with strong magnetic field, strong corrosive gas, large amount of dust and vibrating or explosive gas. The ambient temperature is 5~40 °C, and the relative humidity is not more than 80%.
