Bar quenching and tempering production line

The bar quenching and tempering production line is an induction heating furnace designed and manufactured for the quenching and tempering of round steel bars. It is currently a professional quenching and tempering equipment for long shafts and round steel bars in the heat treatment industry, gradually replacing the traditional Pit furnaces, trolley furnaces and other heating furnaces have become the mainstream heating equipment for quenching and tempering.

A. Technical requirements for bar quenching and tempering production line

1. The main purpose of the bar quenching and tempering production line: it is suitable for the quenching and tempering of round steel, long shafts, low-carbon alloy steel, stainless steel pipes and other metal workpieces.

2. The hourly output of the bar quenching and tempering production line is 0.5-3.5 tons, and the applicable scope is round steel bar diameter ø20mm-ø160mm. 3. Conveying roller table of the bar quenching and tempering production line: the axis of the roller table and the axis of the workpiece form an angle of 18-21°. The workpiece rotates while feeding at a constant speed, so that the heating is more uniform. The roller table between the furnace body is made of 304 non-magnetic Stainless steel and water cooling, other parts of the roller table made of 45 steel and surface hardened.

4. The roller table grouping of the bar quenching and tempering production line: the feeding group, the sensor group and the discharging group are independently controlled, which is conducive to continuous heating without gaps between the workpieces.

5. Closed-loop temperature control of bar quenching and tempering production line: Both heating and quenching adopt the American Leitai infrared thermometer and form a closed-loop control system with German Siemens S7 to control the temperature accurately.

6. Industrial computer system of the bar quenching and tempering production line: real-time display of the status of the working parameters at the time, and functions of workpiece parameter memory, storage, printing, fault display, alarm and so on.

7. Energy conversion of bar quenching and tempering production line: power consumption per ton is 360-400 degrees.

B. Process flow of bar quenching and tempering production line:

The bar material quenching and tempering production line adopts PLC control, only the bar material is placed in the storage rack manually, and the rest of the actions are automatically completed by the system under the PLC control. A set of programs can be set according to the user’s specifications for each product. When working, only the product specifications to be produced need to be clicked on the touch screen. All actions are automatically completed by the PLC program.

Crane crane → storage platform → automatic feeding mechanism → feeding roller table → induction heating system → quenching induction heating system → infrared temperature measurement → discharge roller table → spray quenching → quenching completed → discharge roller table → cool Feeding mechanism → receiving rack

C. The performance characteristics of the bar quenching and tempering production line:

1. The bar quenching and tempering production line adopts medium frequency induction heating power control, which can realize high-power adjustment, low power consumption and high production efficiency.

2. The bar quenching and tempering production line has fast heating speed and less oxidative decarburization;

3. The bar quenching and tempering production line is fully automatic and intelligent, controlled by PLC touch screen, and has a one-key operation control system.

4. The operation panel of the bar quenching and tempering production line adopts a color liquid crystal display, a large touch screen, a high-definition operation screen, and an operation safety protection system, even the first time users can operate with peace of mind.

5. The bar quenching and tempering production line has a sound operating system and humanized design, which greatly shortens the preparation work for using the equipment. The advanced automatic diagnosis system assists the operator to quickly control the excellent performance of the machine.

6. The bar quenching and tempering production line adopts an intelligent PLC control system to ensure the stability of the induction heating equipment.

7. The conveying system of the bar quenching and tempering production line adopts 304 non-magnetic stainless steel, which is wear-resistant and has a long life.

8. The bar quenching and tempering production line has uniform heating and high temperature control: induction heating is easy to achieve uniform heating, and the temperature difference between core and surface is small.

9. The induction furnace body of the bar quenching and tempering production line is easy to replace: according to the size of the workpiece to be processed, different specifications of the induction furnace body are configured.

10. Bar material quenching and tempering production line has low energy consumption and no pollution: Compared with other heating methods, induction heating has high heating efficiency, no overburning, and no deformation; all indicators can meet user requirements.

11. The design concept of the bar quenching and tempering production line doubles the safety factor, which prolongs the safe service life of the equipment.

The bar quenching and tempering production line is also called round steel quenching and tempering furnace. It is currently one of the main equipment used in the bar quenching and tempering industry. It is mainly suitable for the quenching and Tempering has the advantages of stable operation, environmental protection, low energy consumption and long service life.
