High Frequency Welding ERW Steel Tube Mill HG325

Generally speaking, for example, 1450 rolling mill refers to the length of the working roll of the rolling mill is 1450cm. This is the meaning of HG325 rolling mill, which should be able to roll strip steel with a width of about 300 cm.

The high-frequency pipe welding machine is an electromechanical system that realizes high-frequency welding. The high-frequency welded pipe machine is composed of a welded pipe machine and a welded pipe forming machine. The high-frequency pipe welding machine generally consists of two parts: a high-frequency generator and a feeding device. The function is to generate high-frequency current and control it. The molding machine consists of extrusion roll stands. Its function is to extrude the parts melted by high-frequency current, remove the oxide layer and impurities on the surface of the steel plate, and make the steel plate completely fused into one.

According to the specific load, the frequency range of AC power is between 100.1 and 50KH. To adjust the inverters to the load, all inverters are connected in parallel to matching transformers. A transformer has several primary windings connected in parallel and a secondary winding. The turns ratio of the transformer is fixed. The output capacitor consists of several parallel capacitor blocks. The capacitor is in series with the inductor coil, so the output circuit is also series compensated. The function of the capacitor is to compensate the reactive power according to the requirements of the induction coil, and through this compensation, the resonant frequency of the output circuit reaches the required value. The frequency control system is designed to make the triode always work at the resonant frequency of the system. The resonant frequency is determined by measuring the frequency of the output current. This frequency is then used as the time base signal to turn on the triode.

The output power of the induction heating system is controlled by controlling the output current of the inverter. The above control is completed by the power control card used to control the triode driver. The output power reference value is given by the power reference potentiometer on the IMC control panel, or output to the control system by the external control panel.

After this value is transmitted to the system controller, it is compared with the DC power value measured by the rectifier unit measurement system. The controller includes a limiting function that calculates a new output current setpoint based on a comparison between a reference power value and a DC power measurement. The output power setpoint calculated by the controller is sent to the power control card, which will limit the output current according to the new setpoint. The alarm system works according to the input signal of the alarm card in the IMC and the signals sent by various monitoring devices in the IMC and CRU, and the alarm will be displayed on the workbench.

QFA

Q: Are you manufacturer?

A: Yes. We are manufacturer. We have our own technical team. Welcome to visit us.


Q: What payment terms do you accept?

A: We are flexible on payment terms, please contact us for details!


Q: What info you need before you make the proposal?

A: The pipe diameter and thickness range which you need or the profile drawings material information, your special requirements and speed of the machine.


Q: How do you do QA?

A: We have special team do strict QA, this is our strengths:  

(1)Every gear box will be tested for 8 hours with oil inside to guarantee there is no leak.

(2)Every shaft will be inspected for the centering jumpiness.

(3)Every roller will be checked to make sure it is in the range of tolerance critical parts will be inspected for all dimensions.
