With weld annealing method, the company can produce high-grade steel pipe. Pipe induction annealing apparatus is an induction heater as a main component of the continuous welded mechanical, welded and quenched to just weld the pipe is heated to above the critical temperature, quenched and annealed steel pipe weld, the weld stress and to minimize the potential crack, resulting fine grain structure can be guaranteed to meet all the requirements of the standard tough steel. As the weld rapid local heating, making steel oxidation and deformation are minimal, accurate and consistent diathermy been fine grain structure also makes the entire weld area and base metal converge.
Center console is the core set of equipment, and set up a manual or automatic conversion, automatic function control system consists of PLC, touch control screen, high-precision thermometer, etc., to achieve a complete high-precision closed-loop temperature control, temperature control accuracy of less than 1%, to ensure the stability of the quality of the steel pipe annealing.
Heating temperature can be set by the man-machine interface (touch screen), you set the parameters according to different specifications and material of the pipe. Internal system can store five kinds of equipment operating data to be stored after adjustment for different pipe size, material, and later have the same specification steel annealing can be directly transferred out of its further ensure the stability of the steel annealing quality, very great convenience to users. Programmable controller for water, electricity and all-round monitoring, alarm and event of a failure, the system immediately stop heating, to ensure the safe operation of the system and displays the fault location can quickly find fault, to resume production.
