Induction heating heat treatment and tempering production line of steel bar

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

main application: suitable for Steel bar hardening and tempering equipment, low carbon alloy steels, wind power bolts, anchor bolts, lead screws and hydraulic cylinder rods;

power supply system: hardening 160-1000kw/0.5-4khz, tempering 100-600kw/0.5-2.5khz, hourly output 0.5-3.5t;

scope of application: ø 20- ø 120;

conveying roller table: the axis of the roller table forms an included angle of 18 ~ 21 ° with the axis of the workpiece. The workpiece rotates and advances at a uniform speed to make the heating more uniform. The roller table between furnace bodies adopts 304 non-magnetic stainless steel and is water-cooled.

roller table grouping: the feeding group, sensor group and discharge group are controlled independently, which is conducive to continuous heating without gaps between workpieces.

temperature closed-loop control: both hardening and tempering adopt Leitai infrared thermometer and form a closed-loop control system with Siemens S7, with high temperature control accuracy.

industrial control computer system: real time display of current working parameter status, workpiece parameter memory, storage, printing, fault display, alarm and other functions.

energy conversion: hardening + tempering method is adopted, and the power consumption per ton is 360 ~ 400 degrees.



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

good straightness

FOREVER steel bar induction heating heat treatment hardening and tempering production line is adopted. The straightening function is designed during the heat treatment process, and the steel bar can obtain good straightness after hardening 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 the change of load current, so as to realize the closed-loop control of output power. The product heating temperature control precision is high, and the temperature difference between the core and the surface is small. There will be no harmful gas, smoke and dust and other environmental pollution in the production process.

high degree of mechanization and automation

High intelligent power supply, temperature adjustment, automatic tracking of frequency conversion, adaptive load change, automatic power adjustment and other intelligent advantages. It is a “one button” operation to truly realize automatic and intelligent induction heating.

temperature closed loop, intelligent, PLC general operation control system

The infrared thermometer measures the heating temperature of the billet at the outlet of the induction heating furnace to monitor whether there is overheating or incomplete heating. To control the blank temperature within the target range. It reduces the generation of nonconforming products and ensures the consistency of product quality.
