Pofuna kukonza pamwamba kuuma ndi kuvala kukana wamapaipi amakona anayi, akhoza kukonzedwa ena pamwamba, mwachitsanzo pamwamba pa koyera lawi lamoto, mkulu, wapakatikati pafupipafupi pamwamba kuumitsa ndi mankhwala mankhwala ndi zina zotero.Nthawi zambiri, kuuma kwapakatikati pafupipafupi kumawumitsa ambiri, kumatenthedwa ndi kutentha kwa 850-950.℃.Popeza osauka matenthedwe madutsidwe, kotero Kutentha liwiro si mofulumira kwambiri, mwinamwake izo zidzasungunuka ndi zina zolakwika kuzimitsa ming'alu.Zofunikira zowumitsa ma induction Rectangular Pipe normalizing matrix bungwe makamaka ndi ngale.Madzi ozizira opopera kapena yankho lamadzi la polyvinyl mowa, kutentha kutentha kwapakati pa 200-400.℃, kuuma 40-50HRC, kuuma ndi kuvala kukana kuonetsetsa Rectangular Pipe pamwamba.

Chithandizo cha kutentha kwa chitoliro cha rectangular chilinso ndi zabwino zitatu izi:

(A) High dimensional bata kwa mwatsatanetsatane amakona anayi chitoliro, amene amafuna mwatsatanetsatane mkulu, ayenera kukhalabe dimensional bata, chifukwa sukulu molunjika mu mlengalenga, kuzirala ndi pang'onopang'ono, kotero udindo wa austenite wakhazikika adzawonjezera kuchuluka anasungidwa. austenite minofu amakona anayi chitoliro, ayenera kukhala ozizira mankhwala;

(B) Kuchepetsa quenching kupotoza chifukwa elongated lalikulu ndi amakona anayi chubu, kotero anaumitsa ndondomeko mosavuta opunduka, ayenera mosamalitsa ankalamulira mapindikidwe, kutentha mankhwala ndi sitepe yofunikira mu quenching ndondomeko, ntchito pulasitiki kukhala supercooled austenite makonzedwe ake nthawi, amene ndi sitepe yofunika kwambiri kuonetsetsa mlingo wawo mogwirizana, amene ayenera kutentha kusamba kuzimitsa kapena kuzirala kutentha kuwongola akufuna nthawi ina pamene Kutentha ayenera kupachikidwa pa Kutentha, kuchepetsa mapindikidwe kuumitsa mafuta, kwa mkulu-mwatsatanetsatane kalozera njanji, kuchepetsa mapindikidwe. mpweya nitriding kapena plasma nitriding, etc;

(C) High kuuma lalikulu lalikulu ndi amakona anayi chubu kupirira kukhudzana katundu kutopa, ayenera kukhala ndi kuuma mkulu, choncho ayenera kuumitsa, kapena kuumitsa kapena mankhwala kutentha mankhwala, kenako tempering ndondomeko.
