The oil casing pipe heat treatment furnace of Hebei Forever Electromechanical is a professional solution for the quenching and tempering treatment of oil casing, drill collars and other pipes. Its core technical characteristics and advantages are as follows:
1、 Core configuration
Power system: Adopting SCR fully automatic intelligent series resonant intermediate frequency power supply, the power range covers 50-3000KW, and the frequency is 200-16000Hz. The series resonant design achieves high power factor (>0.95) and low harmonic interference, saving 6-15% energy compared to traditional parallel power supply. Supports single machine dual frequency or multi frequency output (low-frequency preheating, high-frequency heating), with a power consumption as low as 310 degrees per ton (heating to 1150 ℃).
Mechanical structure
Roller conveyor system: The roller axis forms an angle of 18-21 ° with the workpiece, and the workpiece rotates and moves at a constant speed to ensure uniform heating; The roller conveyor between the furnace bodies is made of 304 non-magnetic stainless steel material and water-cooled.
Pier head reheating system: In response to the difference in diameter of the casing pier head, an online tracking induction furnace is equipped for precise reheating, with a temperature difference control of less than 20 ℃.
Sensor design: Made of national standard T2 copper material, supports group or single section quick change (water and electricity quick change connector), and is easy to maintain.
Intelligent control system
PLC fully automatic control, integrated formula management system: automatically matches process parameters after inputting steel grade, outer diameter, and wall thickness parameters.
Multi channel closed-loop system (temperature, voltage): can maintain process stability when the grid voltage fluctuates by ± 20%.
Real time monitoring of infrared temperature measurement ensures uniform heating temperature (small temperature difference between core and surface) and excellent straightness after quenching.
2、 Performance advantages of oil drill pipe hardening and tempering production line
Efficient and energy-saving: High energy conversion efficiency, quenching consumes 280-320 kWh per ton, significantly reducing energy consumption compared to traditional processes.
High stability: meets 24-hour continuous production needs, without workpiece transmission ignition phenomenon.
Environmentally friendly and pollution-free: There are no harmful gas emissions throughout the entire process, which complies with green production standards.
