Hlau hardening

Quenching kab nrib pleb nyob rau hauv steel xa mus rau cov kab nrib pleb uas tshwm sim thaum lub sij hawm quenching txheej txheem, uas yog ib qho ntawm cov txheej txheem kho cua sov siv los txhim kho cov neeg kho tshuab zog ntawm steel. Cov hauv qab no yog qee qhov kev tiv thaiv rau quenching cov kab nrib pleb hauv cov hlau:

1. Kev xaiv cov khoom tsim nyog: Kev xaiv cov khoom siv hlau yuav tsum yog raws li qhov xav tau ntawm daim ntawv thov thiab cov kev cai tshwj xeeb rau cov tawv nqaij, lub zog, thiab ductility. Cov hlau xaiv yuav tsum muaj qhov zoo hardenability thiab muaj peev xwm tiv taus cov kev ntxhov siab uas tshwm sim thaum lub sij hawm quenching.

2. Kev ua kom sov thiab so kom zoo: Tsis ua kom sov thiab ntub cov hlau kom zoo ua ntej quenching tuaj yeem ua rau quenching tawg. Tshav kub cov hlau mus rau qhov tseeb qhov kub thiab txias rau lub sijhawm tsim nyog los xyuas kom meej tias cov qauv zoo ib yam thiab cov carbides tau yaj zoo.

3. Kev tsim nyog quenching media: Kev xaiv ntawm quenching media nyob ntawm cov khoom siv quenched. Qhov nruab nrab quenching yuav tsum tsim nyog rau cov khoom siv, nrog rau cov duab thiab qhov loj ntawm qhov. Piv txwv li, dej feem ntau yog siv rau qhov me me, thaum cov roj siv rau qhov loj, ntau qhov chaw.

4. Kev ua kom txias kom zoo: Tus nqi cua txias yuav tsum tau ua kom haum rau cov khoom siv quenched thiab cov kev cai tshwj xeeb ntawm daim ntawv thov. Cov cua txias uas nrawm dhau tuaj yeem ua rau quenching cov kab nrib pleb, thaum tus nqi qeeb dhau tuaj yeem ua rau tsis txaus hardening.

5. Tempering kom zoo: Tempering yog txheej txheem uas muaj cua sov cov hlau mus rau qhov kub thiab txias tom qab quenching kom txo tau qhov kev ntxhov siab thiab txhim kho ductility. Tempering kom zoo tuaj yeem pab tiv thaiv kom tsis txhob muaj kab nrib pleb tshwm sim.

Hauv kev xaus, quenching cov kab nrib pleb tuaj yeem tiv thaiv tau los ntawm kev xaiv cov khoom tsim nyog, cua sov thiab so, quenching media, cua txias, thiab tempering. Cov kev tiv thaiv no tuaj yeem pab xyuas kom cov khoom siv hlau tau txais kev nyab xeeb thiab kev kho cua sov zoo.
