steel bar hardening and tempering heat treatment production line-Forever furnace

Hebei FOREVER Electromechanical Equipment Manufacturing Co., Ltd. focuses on the R & D and production of induction heating equipment such as steel bar hardening and tempering heat treatment production line, steel bar heating furnace, steel bar heating equipment, steel pipe heat treatment furnace, steel pipe heat treatment equipment, etc. with good technology and reasonable price, welcome to visit and consult!

Technical parameters of steel bar hardening and tempering heat treatment production line:

1. Power supply system: kgps500kw/500hz;

2. Scope of application: diameter 100-600mm; Hourly output: 2.2-2.5 tons.

3. Conveying roller table: the included angle between the roller table axis and the workpiece axis is 18-21 degrees;, The workpiece rotates automatically and advances at a constant speed to make the heating more uniform. The roller table between furnace bodies is made of 304 non-magnetic stainless steel and water-cooled.

4. Feeding system: each axis is driven by an independent motor reducer and controlled by an independent frequency converter; The speed difference output is designed flexibly, and the running speed is controlled by sections.

5. Temperature closed-loop system of steel bar hardening and tempering heat treatment furnace: the annealing process has strict requirements on temperature. We use Leitai two-color thermometer and Siemens S7-300 to form an accurate control system to control the temperature difference of annealing furnace within 10 ℃


Process flow of steel bar heat treatment production line:

The workpiece is placed on the storage rack → automatic feeding device feeding → pinch roll feeding system in front of the furnace → induction heating system in the furnace → hardening and tempering system → pinch roll rapid discharge system → infrared temperature measurement and control system → output system → storage table

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

1. Digital air-cooled induction heating power control, energy saving and environmental protection, low power consumption;

2. Fast heating speed, less oxidation and decarburization, high production efficiency, energy-saving raw materials;

3. Stable and uniform heating, high temperature control accuracy, small temperature difference and no pollution;

4. The fully automatic intelligent human-machine interface PLC control program has the function of “one key start”;

5. The induction heating equipment has complete protection functions, and the remote Bar induction heating equipment has automatic alarm function in case of failure, with strong operation reliability;

6. Automatic feeding, 24-hour continuous operation, power saving, environmental protection, cost reduction and manpower expenditure.

Recipe management function:

The powerful formula management system can automatically call relevant parameters after inputting the parameters of steel type, pipe diameter and wall thickness to be produced, without manually recording, consulting and inputting the parameter values required by various workpieces.

Historical curve function:

The traceable process history curve (standard configuration of industrial computer system) permanently saves all product process records for decades.


The traceable process data table can take out multiple groups of sampling points on each product to accurately reproduce the processing temperature values of each section of a single product. The touch screen system can store about 30000 process records, which can be backed up by USB flash disk or network; In the industrial computer system, all product process records within decades are permanently stored without any storage space restriction.
