steel pipe heat treatment production line

Introduce:The heat treatment production line for steel pipes is suitable for heating, quenching and tempering of steel pipes, round pipes and round bars, providing the selection method of steel pipe heat treatment production line, the selection of furnace body structure for steel pipe heat treatment production line, the power supply selection method for steel pipe heat treatment production line, and the parameters of steel pipe heat treatment production line. Method of choosing.
  • Introduction
  • Consultation

Process requirements:

1. Material: 27SiMn;

2. specification:

Specifications (diameter * length): Φ 42 ; length: 6000mm ;

Wall thickness: 11 mm

1. The steel pipe is heated to a quenching temperature by an intermediate frequency, then cooled and quenched, and tempered online.

Quenching heating temperature: 930~950°C

Tempering heating temperature: 520~ 6 50°C

  Overall design overview:

1. The heat treatment of the steel tube is actually a quenching and high temperature tempering composite heat treatment process.

The complete production line is mainly composed of a mechanical conveying device, an intermediate frequency quenching heating module, an intermediate frequency tempering heating module, a closed cooling system, an infrared temperature measuring device, a quenching cooling device, and a main console. The mechanical conveying device comprises a material storage table, a material feeding frame, a track feeding device, a straightening machine, a discharging frame, a quenching heating process of the steel pipe adopting intermittent heating, and the tempering heating adopts continuous heating; ensuring uniform temperature and reducing deformation.

Steel pipe heat treatment process and work process description :

1. Heat treatment process: steel pipe is placed on the loading platform by the crane to carry out the baling → feeding machine feeding → variable frequency feeding roller conveyor to transport the steel pipe forward → medium frequency induction heating sensor (heating) heating to 95 0 °C infrared measurement and temperature control feedback loop consisting of regulating power → induction heating furnace (normalized) normalizing induction furnace → (holding temperature) and 950 deg.] C IR temperature control feedback loop consisting of regulating induction heating furnace power up feeder → discharging .
