Product Features:1Temperature control, using 30 segment intelligent programmable instrument thyristor control

2Can connect to computers and operate multiple devices online

3Using imported fiber materials with high fire resistance and energy efficiency

4Adopting a double-layer furnace shell with low surface temperature

5Overload and over temperature of current and voltage, automatic power-off of broken couples; Grounding *, etc

6It can be pre evacuated, protected by atmosphere, and can also be sintered under high vacuum

Main technical parameters

1、 The maximum temperature is 1100 ℃ -1800 ℃, and the heating zone is 300mm.

2The furnace body adopts a double-layer furnace shell structure, with fans installed between the double-layer furnace shells to quickly raise and lower the temperature, and the surface temperature of the furnace shell is low.

3The furnace tube adopts high-purity quartz tube or corundum tube, and both ends are sealed with SUS304 high vacuum flange.

4The furnace material is made of imported alumina polycrystalline fiber vacuum adsorption, which saves 60% energy compared to traditional electric furnaces and operates at 1100 ℃The electric furnace is composed of two parts, the upper part of the furnace can be flipped backwards as a whole at 110 ℃, and the electric furnace above 1100 ℃ is integrated for easy access to experimental materials and replacement of furnace tubesThe heating element adopts Swedish Kantar resistance wire, silicon carbon rod, and silicon molybdenum rod.

5、The temperature control system of the electric furnace adopts artificial intelligence regulation technology, with an instrument control accuracy of ± 1 ℃. It has PID regulation, fuzzy control, self-tuning ability, and can be programmed with various heating programs,Equipped with ultra-high temperature alarm function, thermocouple damage power-off function, and built-in parameter password control function.
6. Heating rate ≤ 30℃/min(Recommended heating rate ≤ 10)℃/min）It can write a 30 segment automatic heating program, controlled by a thyristor, equipped with a digital LED voltmeter and ammeter.
7. Optional RS-485 communication interface, data management software, with paperless recording of historical data and temperature rise curves, correction of temperature deviation errors, and the ability to manage multiple devices and remotely diagnose and analyze faults.
8. Multiple safety protection designs, good safety performance, and long service life.

9Electric furnaces can be evacuated and filled with atmosphere, with a vacuum degree of up to 10pa (mechanical pump). If a higher vacuum degree is required, a molecular pump can be chosen, reaching 6.67x10-3pa.
