Main technical parameters

Main technical parameters of steel bar quenching and tempering production line:

Main application: Suitable for quenching and tempering heat treatment of steel bars, low-carbon alloy steel, wind turbine bolts, foundation bolts, lead screws, and hydraulic cylinder rods; ·Power supply system: quenching 160-1000KW/0.5-4KHz, tempering 100-600KW/0.5-2.5KHz, hourly output 0.5-3.5 tons;

·Scope of application: 020-0120;

Conveyor roller conveyor: The axis of the roller conveyor forms an angle of 18-21 ° with the axis of the workpiece. The workpiece rotates while moving forward at a constant speed, making heating more uniform. The roller conveyor between the furnace bodies is made of 304 non-magnetic stainless steel and water-cooled.

Roller grouping: The feeding group, sensor group, and discharge group are independently controlled, which is beneficial for continuous heating without creating gaps between workpieces.

Temperature closed-loop control: Both quenching and tempering use Leitai infrared thermometers and form a closed-loop control system with Siemens S7, with high temperature control accuracy.

·Industrial control computer system: Real time display of the current working parameter status, workpiece parameter memory, storage, printing, fault display, alarm and other functions.

Energy conversion: using quenching+tempering method, with a power consumption of 360-400 kWh per ton.

Advantages and characteristics

Advantages and characteristics of steel bar quenching and tempering production line:

Good straightness

Adopting the Forever steel rod induction heating and heat treatment quenching and tempering production line, the straightening function is designed during the heat treatment process, and the steel rod can achieve considerable straightness after quenching and tempering; Uniform heating temperature, high temperature control accuracy, small temperature difference, and no pollution

Forever series variable frequency power supply is easy to directly and accurately detect changes in load current, thereby achieving closed-loop control of output power. The product has high precision in heating temperature control and small temperature difference between the core and the surface. There will be no harmful gases, smoke, or other environmental pollutants during the production process.

·High degree of mechanization and automation

The high degree of intelligence in power supply, temperature adjustment, frequency conversion automatic tracking, variable load adaptive, power automatic adjustment and other intelligent advantages enable "one click" operation, truly realizing automated and intelligent induction heating.

·Temperature closed-loop, intelligent, PLC overall operation control system

Infrared thermometer measures the heating temperature of the billet at the outlet of the induction heating furnace, monitoring for overheating or incomplete heating. To control the temperature of the billet within the target range. Reduced the generation of non-conforming products and ensured consistency in product quality.
