Chifukwa chiyani musankhe ma frequency olondola a ng’anjo yosungunuka

Kusankha chowotcha kutentha ndi mafupipafupi osayenera zidzakhudza ubwino wa kutentha kwa workpiece: kukula kwa mphamvu; vuto kudziwa liwiro Kutentha ndi processing dzuwa la workpiece; nthawi yotentha imachedwa, mphamvu ya workpiece ndi yochepa, kutentha kumakhala kosagwirizana, ndipo kutentha sikungathe kukwaniritsa zofunikira. Zimayambitsa kuwonongeka kwa workpiece ndikuyambitsa zosiyana.

Momwe mungasankhire pafupipafupi moyenera? Chonde kumbukirani mawu otsatirawa:

(1) Kukula kwake kwa workpiece, kutsika kwafupipafupi kuyenera kukhala;

(2) Kusazama kozimitsira wosanjikiza, kumakwera pafupipafupi;

(3) Kuchuluka kwa voliyumu yowotcherera, kutsika kwafupipafupi kuyenera kukhala.

Ubwino wa kuzimitsa pamwamba pa ng’anjo yapakatikati yosungunuka poyerekeza ndi kuzimitsa kwapamtunda kwa zida zowotchera wamba:

1. Kuthamanga kwachangu ndikofulumira kwambiri, komwe kumatha kukulitsa kusintha kwa kutentha kwa thupi A ndikuchepetsa nthawi yosintha.

2. Pambuyo kuzimitsa, zabwino kwambiri cryptocrystalline martensite angapezeke pamwamba pa workpiece, ndi kuuma apamwamba pang’ono (2～3HRC). Low brittleness ndi mkulu kutopa mphamvu.

3. The workpiece kukonzedwa ndi ndondomekoyi si kophweka oxidized ndi decarburized, ndipo ngakhale workpieces akhoza mwachindunji anasonkhana ndi ntchito pambuyo processing.

4. Wosanjikiza wozama, wosavuta kuwongolera ndikugwiritsa ntchito
