INQUIRY

This box Furnace uses silicon molybdenum rods as heating elements, and adopts a double-layer shell structure and a Yudian program temperature control system. The furnace is made of alumina polycrystalline fiber material, and the double-layer furnace shell is equipped with an air cooling system, which can quickly increase and decrease the temperature.

And it has the functions of over temperature, broken couple, over current protection, etc. The furnace has the advantages of balanced temperature field, low surface temperature, fast temperature rise and fall rate, energy saving, etc.

It is an ideal product for high temperature sintering, metal annealing and quality inspection in universities, scientific research institutes, industrial and mining enterprises.

Trigger	1. Phase-shift trigger (with soft-start and current-limiting function) 2. Current limiting function: When adjusting the heating time, the secondary current of the electric furnace after passing through the transformer is limited within 160A, which protects the equipment limitedly. 3. Soft start function: the current will gradually increase when the machine is turned on, and the impact on the heating element is small, which is conducive to prolonging the life of the heating element.
Heating rate	≤30℃/ Min
Recommended heating rate	≤15℃/ Min
Control method	Using Yudian program temperature control instrument (standard) 1. 50-segment program temperature control intelligent PID adjustment. 2. With over-temperature protection and couple-break protection, the heating circuit of the electric furnace will be automatically cut off when the over-temperature or couple is broken. (When the temperature of the electric furnace exceeds 1720 degrees or the thermocouple is blown, the AC relay on the main circuit will be automatically disconnected, and the main circuit will be cut off. open, The ON light on the panel is off, the OFF light is on, limited protection of the electric furnace). 3. It has the function of power-off protection, that is, when the furnace is powered on after power-off, the program does not start to rise from the initial temperature, but from the time of power-off, the furnace temperature starts to rise. 4. The instrument has the function of temperature self-tuning
safety protection system	With insurance and air switch When the current exceeds the rated current of the air switch, the air switch will automatically trip, effectively protecting the electric furnace.
Door opening protection system	There is a travel switch, when the furnace door is opened, the power supply is automatically cut off to prevent the danger of electric shock from touching the heating element

Precautions:

1. For safety, please put the stove in a ventilated place.

2. In order to prolong the service life of the furnace, we recommend that the heating rate should not exceed 10℃/min. The cooling rate does not exceed 5°C/min.

3. The furnace has no vacuum tightness, and it is forbidden to introduce toxic or explosive gases

4. It is forbidden to put the material directly on the bottom brick, please put the material in a special crucible.

5. When heating, the material and crucible should not touch the heating element and thermocouple

6. When not in use for a long time, please use the oven again.
