Din2391 kev xa khoom
| Lub npe | Cim | Kev piav qhia |
| Txias tiav (nyuaj) | BK (+C) | Cov raj tsis tau txais kev kho cua sov tom qab qhov kawg txias txias thiab, yog li, muaj kev tiv thaiv siab heev rau deformation. |
| Cold tiav (Soft) | BKW | Kev kho cua sov zaum kawg yog ua raws li kev kos duab txias uas muaj kev txwv tsis pub deformation.Kev tsim nyog ntxiv tso cai rau qee qhov kev ua kom txias (xws li khoov, nthuav dav) |
| (+ LC) | ||
| Txias tiav thiab kev ntxhov siab | BKS(+SR) | Kev kho cua sov yog siv tom qab lub caij txias kawg.Raws li cov txheej txheem ua haujlwm tsim nyog, qhov nce ntxiv ntawm cov kev ntxhov siab uas cuam tshuam cuam tshuam ua rau ob qho tib si tsim thiab machining mus rau ib qib twg. |
| Annealed | GBK (+A) | Cov txheej txheem txias txias kawg yog ua raws li kev sib tsoo hauv qhov chaw tswj tau. |
| Li qub | NBK (+ N) | Cov txheej txheem txias txias kawg yog ua raws li los ntawm annealing saum toj kawg nkaus transformation point nyob rau hauv ib qho chaw tswj. |
Tsim cov txheej txheem thiab qhov zoo
Cov khoom siv steel hlau, tom qab kos duab precision, oxidation dawb thiab ci kev kho cua sov (NBK lub xeev), kev kuaj tsis muaj kev puas tsuaj, kev kub ntxhov siab thiab cov kua qaub pickling ntawm lub puab qhov ntawm cov yeeb nkab steel, tiv thaiv xeb roj kho rau sab hauv thiab sab nrauv phab ntsa. ntawm cov yeeb nkab steel, thiab kev kho plua plav tiv thaiv rau ob qhov kawg ntawm lub hau.
1. Th sab hauv thiab sab nrauv phab ntsa ntawm cov yeeb nkab steel tsis muaj oxide txheej;
2.Nrog kev kub siab, tsis muaj to, siab precision, siab smoothness;
3. Txias dabtsi yog khoov yam tsis muaj deformation, nthuav dav, flattening tsis muaj kab nrib pleb;
4. Kev kho qhov chaw xeb tiv thaiv.
