Daim ntawv thov ntawm quenching thev naus laus zis hauv kev tsim cov tsheb ciav hlau yog cov txheej txheem tseem ceeb, tsuas yog siv los txhim kho lub hardness, hnav tsis kam thiab nkees tsis kam ntawm ntsia.
Cov hauv paus ntsiab lus ntawm quenching quenching yog hais txog tus qauv kev kho cua sov hauv qhov chaw kub kom ua rau nws txias dua (feem ntau yog dej txias (feem ntau yog dej txias) kom tau txais cov qauv roj. Rau cov ntsia, quenching tuaj yeem txhim kho nws cov npoo tawv thiab hnav tsis kam thaum tswj hwm kev nruj ntawm cov tub ntxhais.
Cov kauj ruam tseem ceeb:
- Preheating: Txhawm rau tiv thaiv cov kev sib tsoo los ntawm kev tawg vim yog kev hloov pauv kub tam sim ntawd, lawv feem ntau preheated ua ntej.
- Cov cua sov: cua sov cov ntsia mus rau ntawm 850 degree thiab 950 degree kom ntseeg tau tias tag nrho cov cross ntu yog ua kom tiav.
- Cua txias: Siv cov nruab nrab uas tsim nyog (xws li dej lossis cov tshuaj polymer) rau cov qauv nrawm nrawm los ua tus qauv martens.
- Tempering: Txhawm rau txo cov kev ntxhov siab sab hauv thiab kho lub hardness, cov ciav hlau quench yuav tsum tau ua kom sov sov.
