This series of pit type quenching heat treatment furnace is a large-scale heat treatment equipment independently developed and manufactured for rod, shaft, wind impeller and other products by our company with the introduction of foreign advanced heat treatment and tempering technology and equipment manufacturing.

Equipment characteristics:
1. Design concept
● This series of all fiber lining heat treatment furnace introduced foreign advanced technology, adhering to the European industrial furnace with high performance, high degree of automation, simple operation interface easy to learn characteristics;

2. Automatic control
● Electric heating multi-zone synchronous control technology, once again up the furnace one key operation, the whole process record, automatic and rapid completion;
● Load constant current, constant voltage, constant power control technology, according to different load characteristics, effective protection of power failure caused by damaged load problem;
● Multiple time curves can be set, the total number of curve segments up to 50;
● With “given value + time value” and “temperature rise section + constant temperature section” two program setting mode is optional;
● All parameters can be set by the key, the data will be saved automatically without loss;

3, All English operation interface
● Touch screen integrated control, English interface, simple operation;

4, Furnace sealing
● The equipment furnace cover and furnace body adopts double soft sealing device and hydraulic cylinder side push soft sealing device;

5, High sealing energy saving
● The front panel of the furnace is made of heat-resistant cast iron to prevent heat leakage from thermal deformation and save energy consumption

6. High uniformity of furnace
● The use of power distribution mode to ensure that the furnace temperature uniformity to meet the process requirements, furnace uniformity up to within ±8℃;

7. Protective device
● Overtemperature controller is used to monitor the upper limit temperature in the furnace, and the power will be automatically cut off when the temperature is over.
● Support to close the output when the furnace door switch is disconnected;
