1 Introduction

Prestressed steel bars are widely used for bridge construction, wall construction and other large structures, which requires the use of steel bars with certain specifications and requirements. In order to ensure the quality of these specified steel bars, the thermal treatment process is very important. Thermochemical treatments are used to improve the mechanical properties of Prestressed steel bars, such as improved strength and elasticity. The necessary process is to heat the steel bar to a certain temperature in an environment-controlled furnace, and then quenching it in a certain liquid.

2 Prestressed steel bar thermochemical treatment production line

The Prestressed steel bar thermochemical treatment production line includes induction heating furnace and quenching furnace and other equipment.

(1)Induction heating furnace. The induction heating furnace is the key equipment of the Prestressed steel bar thermochemical treatment production line, which is used to heat the Prestressed steel bar before quenching treatment. The induction heating furnace operates through an induction coil, which generates a strong magnetic field, thus heating the Prestressed steel bar by induced current.

(2) Quenching furnace. The quenching furnace is used to cool the softened Prestressed steel bar after the induction heating treatment. This machine is specially designed to meet the requirements of this thermochemical treatment process, and can precisely control the temperature of the quenching liquid, thus avoiding overheating and damaging the Prestressed steel bar.

3 Advantages

The Prestressed steel bar thermochemical treatment production line has many advantages compared with traditional treatment processes.

(1) Improve production efficiency. The production line can continuously improve the thermal treatment process of the Prestressed steel bar, so that the production efficiency of the Prestressed steel bar is greatly improved compared with the traditional thermal treatment process.

(2) Replace manual labor. With the Prestressed steel bar thermochemical treatment production line, manual labor can be replaced. This greatly reduces the labor intensity of workers and greatly improves their work efficiency.

(3) Maintaining product quality. The production line can precisely control the process parameters, so that the quality of the Prestressed steel bar produced is guaranteed, and the product quality is improved by the thermal treatment process.

4 Conclusion

The Prestressed steel bar thermochemical treatment production line combines induction heating furnace and quenching furnace and other equipment, and this production line can continuously improve the thermal treatment process of the Prestressed steel bar, so that the production efficiency of the Prestressed steel bar is greatly improved. In addition, manual labor can be replaced and product quality can be guaranteed.

The heat treatment production line of prestressed steel bars is mainly used for the heat treatment of prestressed steel bars, which can eliminate the inner stress generated by the cutting, machining, welding and other processes which cause the products to deform or break. The heat treatment production line consists of rapid heating equipment, dynamometer, long time step-by-step cooling equipment, sensing device with automatic feedback, recording and controlling device and process monitoring system.

The heat treatment production line of prestressed steel bars firstly heats the steel bars rapidly at a high speed, while testing and controlling the temperature data of the steel bars in the process. After heating it to its required temperature, it will cool the steel bars slowly and step by step, the cooling process can eliminate the internal stress generated by the external processing of the steel bars, so as to improve the performance of the steel bar. During the whole process, the temperature sensor will provide the data to the controlling device, which will help to record the temperature changes and sound an alarm when reaching the required temperature. The process monitoring system will help to check the working performance of the equipment, if necessary, the system can even stop the production line automatically to ensure the product quality.

The heat treatment production line of prestressed steel bars will greatly improve the yield and performance of the steel bars. With its real-time monitoring, it can ensure the temperature measurement is carried on in the temperature control range, assuring the fantastic performance of the products. In addition, its automation to the largest extent possible greatly reduces the labor demand and cost.
