Title: Large diameter steel tube quenching and tempering production line - quenching and tempering heating furnace, quenching and tempering production line , heat treatment medium frequency heating furnace manufacturer

Keywords: large diameter steel tube quenching and tempering production line

Description: Suitable for steel, steel rod, heating quenching and tempering, providing large diameter steel tube quenching and tempering production line composition selection method, large diameter steel tube quenching and tempering production line furnace structure selection, large diameter steel tube quenching and tempering production line power supply Selection method, selection method of parameters for quenching and tempering production line of large diameter steel pipe.

 2700KW large diameter steel tube quenching and tempering production line

  The large-diameter steel tube quenching and tempering production line meets the quenching and tempering process of the diameter of φ325～φ1067 steel pipe . The medium frequency induction heating furnace is divided into two areas of heating and equalizing temperature, and the temperature equalizing area can be controlled by independent ring, which can repair the temperature difference of the tube to meet the process requirements. The quenching and tempering of the workpiece are carried out separately in the same production, that is, the quenching process and the tempering process of the large-diameter pipe are respectively completed by the relevant parameters of the preparation .

Tube tempering heating work process: storage, feeding, roller transmission, heating, temperature equalization, discharging, cutting, etc.

Tube quenching heating work process: storage, feeding, roller transmission, heating, temperature equalizing, spraying, cooling, discharging, cutting, etc.

Heating control is divided into automatic control and manual control. The heating temperature is ring control and manual control, and the maximum workpiece exit temperature should meet the specified process requirements of the workpiece.

The medium frequency induction heating furnace and the heat preservation electric furnace are used to realize the heating function required by the following technologies:

(1) Workpiece name: oil casing, high pressure furnace tube, pipe, etc.

(2) (2) Workpiece diameter range: Φ325mm-Φ1067mm

(3) Tube wall thickness: 10mm-30mm.

(4) Length of heatable tube: 6.0m-13m.

(5) Tube heating maximum temperature: 1050 °C.

(6) Maximum temperature difference (circumferential and radial): ±15°

(7) Tube walking speed: 3mm/S-30mm/S;

(8) Tube motion and sensor power control can realize linkage control with PLC and automatic temperature control.

(9) Process requirements: The temperature of the rear tube heated to 1050 ° C.

(10) Production: 5 tons / hour

Process parameters of large diameter steel tube quenching and tempering production line :

Φ325mm-Φ1067mm range. The induction heating temperature is 1050 °C. Production: 18,000 tons / year.

Frequency induction furnace using multiple KGPS frequency power supply and a plurality of sensors into groups. Quenching main heating zone: a power source equipped with a sensor, so that the power supply can control independently an induction may increase the accuracy of heating temperature, heating may be achieved for each matching inductor stepless adjustable power, and can realize closed-loop temperature Control . The heating unit uses four independent heating units, each unit uses a 600KW medium frequency power supply with a 800-1000mm long sensor. The advantages are: single power is small, stability is high, and the independent frequency of each power supply can be increased according to the pipe specification, and the heating efficiency is improved.

Tempering isothermal heating zones: 1 300KW and the power control IF, IF power with separate sensors, temperature sensors have holes, with far-infrared temperature of the tube temperature measurement and control. The sensor length is 800-1000mm .
