Nyob rau hauv cov khoom siv toj roob hauv pes, cemented carbide thiab steel yog ob qho tseem ceeb players. Cia peb rhuav tshem lawv qhov sib txawv ntawm qhov loj me los pab koj nkag siab thaum siv txhua!
I. Kev tshuaj ntsuam xyuas
Cov khoom 'cov khoom yog los ntawm lawv cov kev sib xyaw - ntawm no yog li cas ob pawg no:
(1) Cemented Carbide muaj pes tsawg leeg
- Core Structure: Ua los ntawmhard compounds (piv txwv li, tungsten carbide, titanium carbide)thiab abinder hlau (feem ntau cobalt).
- Vim Li Cas Nws Tseem Ceeb:
- Cov khoom sib xyaw ua ke muab cov tawv tawv heev thiab hnav tsis kam.
- Cov binder hlau "glues" cov tebchaw, ntxiv kom txaus toughness kom tsis txhob brittleness.
(2) Steel Composition
- Core Structure: Feem ntau hlau (Fe) nrogcarbon (C)thiab xaiv tau alloying ntsiab (xws li, manganese, chromium, nickel).
- Vim Li Cas Nws Tseem Ceeb:
- Cov ntsiab lus carbon drives hardness / zog (siab dua carbon = harder, tab sis tsawg ductile).
- Alloying ntsiab kho cov khoom: Chromium boosts corrosion kuj; npib tsib xee txhim kho toughness.
II. Kev ua yeeb yam
Cia peb sib piv lawv qhov tseem ceeb mechanical thiab lub cev zoo:
| Khoom | Cemented Carbide | Hlau |
|---|---|---|
| Hardness | Ultra-siab (HRA 89–93, ~ HRC 74–81) | Nruab nrab (HRC 20–65, nyob ntawm qib) |
| Hnav Resistance | Exceptional (outlasts steel nyob rau hauv abrasion) | Zoo (tab sis ua tsis tau sai nyob rau hauv high-wear apps) |
| Toughness | Tsawg (nkig; nquag tawg hauv qhov cuam tshuam) | Siab (hloov tau; absorbs shocks) |
| Thaum tshav kub kub Resistance | Khaws hardness mus txog 800-1000 ° C | Poob lub zog siab dua 400 ° C (rau cov hlau dawb) |
| Corrosion Resistance | Tsim nyog nyob rau hauv tej qhov chaw (xws li, qhuav machining) | Yuav tsum tau alloys (piv txwv li, stainless hlau) kom zoo kuj |
Kev cuam tshuam tiag tiag hauv ntiaj teb ntawm kev ua haujlwm tsis zoo
- Cemented Carbide ci ntsa iabnyob rau hauv cov cuab yeej txiav (xws li, laum cov khoom) thiab cov mining - qhov twg hnyav hnyav / kub dominate.
- Steel Excelsnyob rau hauv cov khoom siv (xws li, tsheb thav duab, txuas hniav) - qhov twg toughness thiab nqi-zoo zog teeb meem.
III. Daim ntawv thov teb
Lawv qhov kev ua tau zoo sib txawv kaw lawv mus rau hauv cov luag haujlwm sib txawv:
(1) Cemented Carbide daim ntawv thov
- Cov cuab yeej txiav: milling cutters, laum cov khoom (kaws high-speed hlau txiav).
- Mining / Drilling: Pob zeb-drilling tswv yim, tunnel-boring cuab yeej (resists abrasive pob zeb).
- Aerospace: Precision Cheebtsam (xws li, turbine qhov chaw) xav tau cua sov / hnav tsis kam.
(2) Kev siv hlau
- Kev tsim kho: Rebar, kab teeb (nyob ntawm lub zog + ductility rau kev nyab xeeb).
- Automotive: Chassis, cav qhov chaw (sib npaug zog, toughness, thiab nqi).
- General Machinery: Gears, shafts (ntau yam hla qhov kev ntxhov siab tsawg-rau-siab).
IV. Tus nqi tsim khoom & kev ua haujlwm
(1) Cov nqi sib piv
- Cemented Carbide: kim vim:
- Cov ntaub ntawv tsis tshua muaj (tungsten, cobalt).
- Complex hmoov metallurgy (nias + sintering).
- Hlau: Affordable vim:
- Muaj hlau / carbon.
- Mature ntau lawm (smelting, dov).
(2) Kev ua haujlwm nyuaj
- Cemented Carbide: Nyuaj rau lub tshuab-yuav tsum tau EDM (hluav taws xob tawm machining) lossis laser txiav.
- Hlau: Yooj yim rau cov duab - forged, dov, los yog txiav nrog cov cuab yeej txheem.
V. Yuav xaiv li cas?
Xaiv raws li:
- Ib puag ncig:
- Kub kub / abrasion? → Cemented carbide.
- Kev poob siab / cuam tshuam? → Hlau.
- Kev xav tau kev ua haujlwm:
- Hardness heev? → Cemented carbide.
- Ductility / toughness? → Hlau.
- Nyiaj txiag:
- Nqi-sensitive? → Hlau.
- Performance justifies premium? → Cemented carbide.
Xaus: Xaiv Wisely rau koj xav tau
Cemented carbide thiab hlau tsis yog sib tw - lawv yog cov cuab yeej tshwj xeeb. Siv cov carbide rau cov mob hnyav; lean ntawm steel rau ntau yam, raug nqi zog.
