Automatic constant temperature function of MEDIUM frequency

Automatic constant temperature function of MEDIUM frequency tube expanding machine  

Intelligent constant temperature features:  

1, the intelligent control of intermediate frequency power supply at the time of expanding production will steel tube heated to the required temperature and constant, especially in the thermal expansion of high alloy steel pipe, more can reflect the superiority of the system to adapt to the thermoplastic deformation temperature area narrow, effectively avoid the human factors caused by the alloy steel pipe burnt (high temperature) to produce the scrap quality decline and die for steel tube,  At the same time, it avoids the fracture phenomenon of the pull rod or die caused by the increase of the thrust of the thermal expansion unit due to the low temperature.  Ensure the safe operation of the thermal tube expanding unit and eliminate unsafe factors.  

2, intermediate frequency expanding machine intelligent constant temperature system of intermediate frequency power supply with constant temperature heating one, thus ensuring thermal expansion pipe heating is always in a state of constant temperature, compared with the manual operation of steel pipe heating, energy conservation, environmental protection, simplify the operation procedures, reduce the labor costs, can achieve a operators at the same time monitoring the ten most normal production expansion tube expanding unit,  And through the pressure, speed, temperature programming overload protection.  It completely eliminates the unsafe factors caused by the high pressure of the pipe expanding unit in the pipe expanding production.  

3, each set set two temperature measuring points intelligent automatic temperature control, according to the preset heating temperature of different grades of steel pipe, select the heating temperature of steel pipe to be expanded and keep constant, and real-time display and record, can print and save the real-time curve of heating temperature parameters and historical curve.  At the same time, it automatically stores relevant information such as temperature, time, working pressure, speed and so on, so as to guarantee the traceability of data.  1817
