Chifukwa chiyani galasi lazimitsidwa?

Kuzimitsidwa kwa galasi ndikutenthetsa galasi mpaka kutentha kwa T, pamwamba pa 50 ~ 60 C, ndiyeno mofulumira komanso mofanana kuziziritsa mu sing'anga yozizira (monga quenching sing'anga) (monga mpweya utakhazikika quenching, madzi utakhazikika quenching, etc.) Chosanjikiza ndi pamwamba pake chidzapanga kutentha kwakukulu kwa kutentha, ndipo kupanikizika komwe kumabwerako kumakhala kosavuta chifukwa cha kutuluka kwa magalasi, kotero kutentha kwa kutentha koma palibe vuto lopanikizika limapangidwa.Mphamvu yeniyeni ya galasi ndi yotsika kwambiri kuposa mphamvu zamaganizo.Malingana ndi makina ophwanyidwa, galasi ikhoza kulimbikitsidwa popanga kusanjikiza kovutirapo pagalasi (yomwe imadziwikanso kuti tempering yakuthupi), zomwe zimachitika chifukwa cha makina omwe amagwira ntchito yayikulu.

Pambuyo kuzirala, kutentha kwa kutentha kumachotsedwa pang'onopang'ono, ndipo kupanikizika kosasunthika kumasandulika kukhala kupsinjika kwabwinoko, zomwe zimapangitsa kuti pakhale kugawanika kwapang'onopang'ono pa galasi pamwamba pa galasi.Ukulu wa kupsinjika kwamkati uku kumagwirizana ndi makulidwe a mankhwala, kuzizira kwa kutentha ndi coefficient yowonjezera.Choncho, akukhulupirira kuti pamene galasi woonda ndi galasi ndi otsika kukulitsa coefficient ndi zovuta kuzimitsa zozimitsa galasi mankhwala, structural zinthu zimagwira ntchito yaikulu;, ndi chinthu cha makina chomwe chimagwira ntchito yaikulu.Mpweya ukagwiritsidwa ntchito ngati sing'anga yozimitsira, umatchedwa kuzimitsa kwa mpweya;pamene zamadzimadzi monga girisi, manja silikoni, parafini, utomoni, phula, ndi zina zotero. ntchito monga sing'anga quenching, amatchedwa madzi-utakhazikika quenching.Kuphatikiza apo, mchere monga nitrates, chromates, sulfates, ndi zina zambiri zimagwiritsidwa ntchito ngati zozimitsa media.Chitsulo chozimitsira chitsulo ndi ufa wachitsulo, waya wachitsulo wofewa burashi, etc.
