What is the structure of the steel pipe heating furnace?
It can be seen from the heating principle and requirements of the steel pipe heating furnace that the structure of the steel pipe heating furnace should ensure the uniformity and heat permeability of the heating temperature of the steel pipe heated as a steel pipe. Therefore, the steel pipe heating furnace must have a certain heating time and temperature measurement, and take certain coil design and manufacturing measures to ensure that the steel pipe is fully heated, thereby improving the quality of the seamless steel pipe.
For steel pipes with smaller diameters, the heating frequency is higher, and for steel pipes with larger diameters, the heating frequency is lower; for steel pipes with large output, the steel pipe heating furnace is designed with a secondary heating concept, that is, the high-power intermediate frequency power supply is used for rapid heating. Make the steel pipe quickly approach the process temperature, and then use a low-power intermediate frequency power supply to heat the interior of the steel pipe to ensure that the temperature difference between the core surface and the axial temperature difference meets the process requirements, so that the heating performance of the heated steel pipe is very good.
