nta ntawm cov khoom siv hluav taws xob ntau zaus

1. Lub tshav kub yog nyob rau saum npoo ntawm lub workpiece, cua kub ceev ceev, thiab thermal efficiency siab.

2. Vim lub workpiece tsis rhuab tag nrho, lub deformation yog me me

3. Lub sij hawm cua sov ntawm lub workpiece yog luv, thiab tus nqi ntawm oxidation nto thiab decarburization yog me me.

4. Lub hardness ntawm lub workpiece yog siab, lub rhiab heev rhiab heev yog me me, thiab qhov cuam tshuam toughness, qaug zog thiab hnav kuj zoo heev. Nws muaj txiaj ntsig zoo rau kev siv lub peev xwm ntawm cov khoom siv, txuag cov khoom siv, thiab txhim kho lub neej kev pab cuam ntawm qhov chaw

5. Cov khoom siv yog compact, yooj yim rau siv thiab ua haujlwm zoo

6. Yooj yim ntawm mechanization thiab automation

7. Tsis tsuas yog siv nyob rau hauv qhov chaw quenching tab sis kuj nyob rau hauv nkag mus rau cua sov thiab tshuaj kho cua sov.
