Kev xaiv cov khoom siv caij nplooj ntoos hlav yuav tsum tau txiav txim siab raws li qhov xwm txheej ntawm lub caij nplooj ntoo hlav, lub xeev kev ntxhov siab, qhov loj ntawm kev ntxhov siab, kev ua haujlwm kub, ib puag ncig nruab nrab, kev pabcuam lub neej, kev xav tau rau hluav taws xob thiab sib nqus conductivity, txheej txheem kev ua tau zoo, qhov chaw ntawm cov ntaub ntawv thiab tus nqi.
Thaum txiav txim siab qhov sib txawv thiab qhov loj ntawm cov khoom, qhov loj me uas tau teev tseg hauv lub teb chaws tus qauv thiab cov qauv kev cai lij choj yuav tsum raug nyiam, thiab cov khoom tsis yog cov qauv yuav tsum zam kom ntau li ntau tau.
Qhov nruab nrab thiab me me, tshwj xeeb tshaj yog muab kauv txuas ntxiv, yuav tsum tau muab qhov tseem ceeb rau kev siv cov hlau txuas ntxiv, cov hlau lead da dej isothermal txias rub hlau hlau thiab roj quenching tempered steel hlau, nrog lub zog siab thiab zoo nto zoo, kev qaug zog yog siab dua li qub quenching. thiab tempering steel hlau, yooj yim ua, zoo manufacturability, ruaj khov zoo.
Tom qab cov duab txias ntawm cov pa roj carbon caij nplooj ntoos hlav steel hlau thiab piano steel hlau, muaj kev ntxhov siab loj heev, thiab tom qab ua tiav lub caij nplooj ntoos hlav, muaj kev ntxhov siab loj, thiab qhov loj me hloov pauv tom qab tempering, thiab nws yog qhov nyuaj los tswj qhov seem. raug. Roj quenching thiab tempering steel hlau yog modulated thiab ntxiv dag zog rau tom qab cov hlau xaim yog kos rau qhov luaj li cas, yeej tsis muaj residual kev nyuaj siab, thiab qhov luaj li cas hloov yog me me heev tom qab tsim lub caij nplooj ntoos hlav, thiab lub tshav kub stability yog zoo dua li ntawm txias-draw reinforced steel hlau.
Rau qhov loj thiab nruab nrab-qhov loj me, cov khoom siv txias los yog cov hlau polished tom qab kos duab txias yuav tsum tau siv rau qhov raug siab thiab kev ntxhov siab. Rau springs nrog tsawg load raug thiab kev ntxhov siab, kub-kuav los tiag steel yog ib qho kev xaiv.
