In addition to surface quenching, what are the other applications of induction heat treatment of mashine ya kuzima masafa ya juu?

Mbali na kuzima kwa uso, matibabu ya joto ya induction ya mashine ya kuzima masafa ya juu pia hutumiwa katika nyanja zifuatazo:

(1) Stress relief and normalizing A flexible water-cooled coil wraps the flush weld of a sleeve, and performs stress relief or annealing at the welding position. Linear short reactor with silicon steel sheet for annealing longitudinal continuous welds of butt welded pipes. The linear inductor heats the weld above the AC3 temperature, which recrystallizes the tissue there. Both ends of the tractor high-pressure oil pipe are cold heading and flared (20 steel), and induction normalizing is also used to restore the grain at the heading head to normal.

(2) Mabomba ya kuzima kupenya na uhandisi wa kisima cha mafuta, kipenyo cha nje ni kati ya φ60 ~ φ410, unene wa ukuta ni kati ya 5 – 16mm, 1000Hz umeme wa mzunguko wa kati umetumika kwa ajili ya kuzima joto la kupenya, kuwasha (600 – 700 mm). ) ℃) pia hufanywa na usambazaji wa umeme wa masafa ya kati. Uzimaji na ubavu wa skrubu ya risasi ukiwa tupu pia umepitishwa kwa ufanisi na upashaji joto wa masafa ya kati.

(3) Application of induction heating for pipe drawing Cold-drawn pipes reduce their diameter in a cold state, and the reduction amount is small each time. In addition, annealing and pickling are required, and the process is complicated. The use of induction heating to draw the tube can increase the diameter reduction by 1.5 times, and cancel the annealing, pickling and other processes.
