Workpiece size: Φ20~Φ160mm

Workpiece length: 2-20m 
Power range: 1 6 0 - 1 000KW 
Closed-loop temperature control: US Leitai two-color thermometer to control temperature 
Control system: PLC human-machine interface automatic intelligent control

Steel pipe heat treatment equipment , can handle specifications Φ 20 ~ Φ 160mm. There are five sets of coils in the whole line, which are controlled by multiple zones by five independently independent variable frequency modules. The last group in each zone is used as a holding zone for better austenitizing effects. The grinding rod cooling system is water-cooled and consists of five quenching water rings and a linear cutting nozzle. The whole process of quenching and tempering of the grinding rod is continuously transmitted by the continuous inclined roller road, and the grinding rod advances by rotation, which can ensure the uniformity of heating and cooling of the grinding rod and obtain better flatness.

 the composition of steel pipe heat treatment equipment :

1. Feeding mechanism and discharging mechanism

2, the conveyor roller (the workpiece rotates on one side, the average speed feeds on one side, and the operation is stable, the speed is adjustable, the heating is more uniform)

3. Quenching induction heating system

4, quenching spray system

5, tempering induction heating system

6, PLC main console (including frequency control and temperature control, Huayan IPC, remote start, etc.) its role is to operate the entire quenching and tempering equipment directly on the center console, only one person can operate the steel pipe Quenching and tempering production line saves labor and saves costs.

7, quenching medium frequency power supply range: KGPS / IGBT   160-1300KW

8, tempering intermediate frequency power supply range: KGPS / IGBT   160-750KW


 the steel pipe heat treatment equipment control system description:


The main console adopts German Siemens PLC and Taiwan Huayan industrial control system as the core control part, which automatically matches and adjusts the whole system mechanical operation parameters, quenching and tempering parameters, power supply, etc., and displays, stores and prints various parameters. And other functions.

1. Recipe management function:

The powerful formula management system automatically inputs the relevant parameters after inputting the steel grade, pipe diameter and wall thickness parameters to be produced, without having to manually record, consult and input the parameter values required for various workpieces.

2. History curve function:

The PLC master console displays the traceable process history curve (standard on the industrial computer system), accurate to 0.1 second recording accuracy, and vividly and accurately reproduces the processing temperature trend graph of a single product. Up to 1T of capacity storage space, permanently storing all product process records for decades.

3. History:

   Traceable process data table, which can take multiple sets of sampling points on each product to accurately reproduce the processing temperature values of each segment of a single product. The touch screen system is completely free of storage space and permanently stores all product process records for decades.


the main purpose of steel pipe heat treatment equipment

Engineering Machinery: quenched and tempered steel, steel bar, rod quenching and tempering heat treatment;

Oil Machinery: rod, geological drill pipe, drill collars quenching and tempering heat treatment;

Coal mine machinery: quenching and tempering treatment of monomer pillars, suspension pillars, metal roof beams, etc.;  

Quenching and tempering technology for pipe / bar quenching and tempering treatment has many significant advantages, mainly as follows:

1. It is used for single-line processing of pipes /bars. It is very fast and flexible. The whole line can be emptied and adjusted for the next batch of materials in a few minutes, with the shortest downtime;

2. All sizes of tubes/bars can achieve the same processing efficiency;

3. Consistency of extremely high hardness and uniformity of microstructure;

4, extremely high toughness and impact strength;

5. No decarburization occurs during heat treatment;

6, very convenient to set the processing line status in line with customer needs;

7. After induction heat treatment technology, the tube/bar can obtain very good straightness after quenching and tempering treatment, which means that it does not cost a lot of money to purchase heavy-duty straightening equipment (can straighten high-strength quenching and back Fire material), no additional process is required to process the material (straightening process).

8. Energy loss and related expenses only exist in effective production;

9, very low maintenance costs, do not need long downtime maintenance.
