Inductor Parameter Design

According to the different parameters of the workpiece,our engineer will optimizatized design different inductor group to get the effect of high efficiency. The inductor for tempering will increase the inductor quantity and adding tempering holding box to get better structure after temepring,ensuring the workpiece performance meets the requirements.


it is a circular spray device made of stainless steel, installed in the discharge end of the inductor, the casing go through from the sprayer.The high-pressure cooling water from the spray hole wall will spray casing for cooling There is water collecting tank below sprayer and the cooling water flows into the quenching circulating pool through water collecting tank.

Mechanical conveying part

Adopting domestic brand Jiangsu Guomao GR67 series hardened motor reducer as the driving power; Using 40Cr steel as the feeding roller which is surface quenched; The rollers between inductors adopts 304 non-magnetic stainless steel and cooling by inputting water.

Why choose Forever continuous hardening and tempering furnace ?

1.Rich experience

Our company has dedicated in designing and manufacturing steel bar quenching and tempering for ten years. So far, we have manufactured almost 100 sets of bar quenching and tempering line. We have deep understanding for different material slight difference. The process is mature and stable, running is reliable.

2.“One key” operation

At present, most manufacturers in China manually adjust and test the parameters of different sizes of steel bars quenching and tempering. However, our technicians have already set up corresponding heat treatment parameters for different specifications of the steel bars for users, only need one worker to operate. The operator only needs to choose different steel bar process No. in the console HMI, the system will run as per the setting parameters. So the operator for this system only need simple training, no need special professional skills. And Programmed operation ensures consistency and stability of product quality compared with manual adjustment.

In the operation of the equipment, there is a complete data monitoring, process records, traceability is strong. The man-machine interface of the console will display production data, such as temperature, current, voltage, water pressure, etc.. The data can be stored in the system for a period of time, which is easier for users to check in future. Users can also download production data to the U disk for long-term storage.

3.As the steel bar has many sizes, the user need to replace different induction heaters to meet production requirement. Our intelligent intermediate frequency power supply doesn’t need any parameter adjustment, which makes user’s operation easier.

4.After our equipment arrived in user’s plant, we will send technician to install and debug the equipment. After our technician finish parameter setting and return to our plant. In future, if the user need to add other size bars process parameters, we can send recipe parameters to customers by internet. User can input the console. vistingcompany
