The effective heating area size shall not be less than 900X400X470mm (length x width x height)

6. Furnace temperature uniformity: ≤± 5 ℃, fan installed behind the furnace, blowing towards the furnace door, 5-point standard temperature measurement

7. Temperature control accuracy: ± 1 ℃

8. Heating element: High quality electric furnace wire from Shougang is used, with a wire diameter of 3-5mm. The lead out rod matches the furnace wire, with a quantity of 6 pieces, 6KW/piece. The electric furnace wire adopts standard type.

9. Heating time: Empty furnace heating time ≤ 30 minutes

10. Furnace material: The bottom of the inner layer of the furnace is made of hard refractory bricks, which are of standard side groove type. The electric furnace wire is installed on both sides of the ceramic

Inside the ceramic fiber board groove, refractory bricks are lined with ceramic fiber material. The top of the furnace and the front door are made of ceramic fiber board material, which is lightweight and has low specific heat. This type of furnace structure not only has the advantages of large load-bearing capacity, thermal shock resistance, and long service life of traditional refractory brick furnaces, but also has the advantages of light weight, low energy consumption, and high cost-effectiveness of fiber furnaces, making it highly applicable in the electric furnace industry market. The top of the furnace is fixed and connected with lifting bolts, and the heating element can be replaced by removing it from the top for easy installation with minimal workload.

11. Control system: This equipment adopts a single point temperature control method, and the temperature control system consists of temperature control instruments, three-phase phase shifters, air switches, temperature control thermocouples, and

Composed of various protective electrical components, all of which are made of high-quality domestic brands. For example, Xiamen Yudian and Chint Electric. It is also equipped with a paperless recorder, which can record the temperature rise process curve and various alarms in real time. All selected instruments and meters for the electric furnace meet the requirements for instrument configuration of Grade II heat treatment furnaces in HB5425-2012.

12. Heating system: This equipment adopts a three sided heating method, and the heating elements are arranged at the bottom of the furnace with different power density distributions

In the grooves on the left and right walls, multi-faceted heating technology can ensure that the temperature uniformity of the equipment meets the requirements of Grade II heat treatment temperature uniformity in HB5425.

13. Temperature control instrument: Adopting Yudian intelligent temperature control instrument, it meets the requirements of Class B instrument in HB5425-2012, with an accuracy level of not less than 0.2,

It is possible to develop 50 temperature rise curves with PID regulation function, power limiting function, over temperature alarm, data communication and other functions.

14. Record storage function: Touch operated paperless recording instrument, which can display and record the heating process curve in real time, and can query historical processes

Curves have multiple display modes and can record data for more than six months. Using dedicated mobile data storage devices, data can be copied to a computer for data analysis or printing.

15. Silicon carbide bottom plate is laid on the refractory bricks at the bottom of the furnace, and multiple pieces are spliced together. 16. Surface temperature rise of the shell: ≤ 40 ℃.
