Quenching yog ib theem ntawm kev ua cov khoom siv nyob rau hauv uas cov khoom raug rau kom txias ceev heev. Cov hlau feem ntau yog quenched thaum lub sij hawm ua, thiab cov polymers kuj yuav raug quenched, nyob ntawm qhov chaw uas lawv siv. Kev xyaum ntawm kev ntxiv quenching da dej immersion rau cov txheej txheem ua cov ntaub ntawv yog heev qub, raws li muaj ntau ancient haiv neeg paub hais tias lub ceev ceev ntawm hlau yuav radically hloov lawv cov khoom. Lawv kuj tau kawm tias cov xov xwm sib txawv tuaj yeem siv rau kev tua thiab ua rau cov txiaj ntsig sib txawv.
Thaum quenching yog ua tiav, cov khoom yuav tsum tau txias sai heev nrog cua, kua polymers, roj, los yog dej. Qee zaum siv ntau tshaj ib txoj kev. Piv txwv li, ib lub hlau yuav txias los ntawm huab cua thiab muab tso rau hauv lub da dej kom tiav cov txheej txheem quenching. Agitation ntawm cov khoom yuav tsim nyog los xyuas kom meej tias cov khoom yog quenched uniformly. Hloov chaw, agitators tuaj yeem siv los txav qhov nruab nrab quenching. Qhov no tiv thaiv qhov sib txawv ntawm qhov kub thiab txias, uas tuaj yeem ua rau cov khoom tsis muaj zog, ua rau cov ntsiab lus los yog deform ib cheeb tsam, yog li ua rau cov khoom puas.
Lub hom phiaj ntawm kev ua cov kauj ruam no yog los tiv thaiv cov theem kev hloov ntawm qhov tshwm sim thaum lub caij txias qeeb. Thaum cov khoom txias txias, lub sijhawm zoo tshaj plaws rau ntau lub sijhawm hloov pauv tshwm sim thiab cov khoom nyob twj ywm hauv qhov kub thiab txias rau lub sijhawm ntev. Thaum lub sij hawm quenching, cov khoom ncav cuag qhov kub thiab txias, tab sis tsis nyob rau hauv qhov kub qhov chaw ntev txaus rau theem transformations tshwm sim. Quenching tseem tiv thaiv nag lossis daus thiab sib cais ntawm cov khoom siv alloying, uas tuaj yeem ua rau cov khoom tsis muaj zog lossis puas.
Cov txheej txheem tsis yog tsis muaj teeb meem. Txawm tias thaum ua kom zoo, quenching tuaj yeem ua rau cov khoom siv warping, tawg, thiab lwm yam teeb meem. Piv txwv li, siv dej los ua cov khoom siv quenching yuav ua rau cov khoom ua kom sov thaum nws txias. Nws yog ib qho tseem ceeb los tswj qhov chaw nyob rau hauv uas lub quench yuav siv sij hawm qhov chaw kom txo qhov kev pheej hmoo ntawm cov khoom puas. Thaum siv kom zoo, cov khoom yuav nyuaj thiab ruaj khov, ua rau nws haum rau ntau yam kev siv.
Cov txheej txheem quenching tuaj yeem ua rau muaj kev phom sij. Cov ntaub ntawv yuav tsum tau quenched yog kub heev thiab thaum immersed nyob rau hauv ib tug quench tank lawv tso tawm ntau vapor uas yuav ua rau hlawv. Nws yog ib qho tseem ceeb uas yuav tsum hnav khaub ncaws tiv thaiv thiab xyuas kom txhua tus neeg nyob ib puag ncig paub txog cov kev phom sij thaum lub sijhawm ua cov khoom siv no.
