Dab tsi yog qhov zoo ntawm cov khoom siv hluav taws xob ntau zaus piv nrog cov cua sov zoo tib yam thiab quenching

1. Cov cua kub ceev ceev heev, uas tuaj yeem nthuav dav qhov kev hloov pauv kub ntawm A lub cev thiab ua kom lub sijhawm hloov pauv.

2. Tom qab quenching, txheej txheej ntawm lub workpiece tuaj yeem tau txais zoo heev cryptocrystalline martensite, nrog me ntsis hardness (2-3HRC), qis brittleness thiab ntau zog qaug zog.

3. Cov workpieces kho los ntawm cov txheej txheem no tsis yooj yim rau oxidized thiab decarburized, thiab txawm tias qee qhov workpieces tuaj yeem ncaj qha sib dhos thiab siv tom qab kho.

4. Cov txheej tawv tawv yog sib sib zog nqus, yooj yim los tswj thiab ua haujlwm, yooj yim kom paub txog kev siv tshuab thiab kev siv tshuab.

5. Cov nplaim nplaim yog rhuab thiab quenched.
