M'malo opangira mafakitale, carbide ya simenti ndi zitsulo ndizofunikira kwambiri. Tiyeni tidutse kusiyana kwawo pamiyeso yayikulu kuti ikuthandizeni kumvetsetsa nthawi yoyenera kugwiritsa ntchito iliyonse!
I. Kusanthula Kapangidwe
Zida zakuthupi zimachokera ku zolemba zawo - umu ndi momwe awiriwa amawunjikira:
(1) Mapangidwe a Cemented Carbide
- Kapangidwe ka Core: Wopangidwa ndimankhwala olimba (mwachitsanzo, tungsten carbide, titanium carbide)ndi abinder zitsulo (makamaka cobalt).
- Chifukwa Chake Kuli Kofunika?:
- Zopangira zolimba zimapereka kuuma kwambiri komanso kukana kuvala.
- Chitsulo chomangira "chomatira" mankhwalawa, ndikuwonjezera kulimba kokwanira kuti zisawonongeke.
(2) Chitsulo
- Kapangidwe ka Core: Kwenikweni chitsulo (Fe) ndimpweya (C)ndi ma alloying osankha (mwachitsanzo, manganese, chromium, faifi tambala).
- Chifukwa Chake Kuli Kofunika?:
- Mpweya wa kaboni umayendetsa kuuma/mphamvu (mpweya wokwera = wovuta, koma wocheperako).
- Zinthu zophatikizika zimasintha makonda: Chromium imathandizira kukana dzimbiri; nickel imawonjezera mphamvu.
II. Chiwonetsero cha Performance
Tiyeni tifananize mawonekedwe awo amakina ndi thupi:
| Katundu | Simenti Carbide | Chitsulo |
|---|---|---|
| Kuuma | Zokwera kwambiri (HRA 89–93, ~HRC 74–81) | Moderate (HRC 20–65, kutengera giredi) |
| Valani Kukaniza | Zapadera (zimatulutsa zitsulo mu abrasion) | Zabwino (koma zimalephera mwachangu pamapulogalamu ovala kwambiri) |
| Kulimba mtima | Zochepa (zosakhazikika; sachedwa kusweka pansi) | Wapamwamba (wosinthasintha; amatengera kugwedezeka) |
| Kukaniza Kutentha | Imasunga kuuma mpaka 800-1000 ° C | Amataya mphamvu kuposa 400 ° C (kwa chitsulo chosavuta) |
| Kukaniza kwa Corrosion | Zabwino m'malo ena (mwachitsanzo, makina owuma) | Pamafunika ma aloyi (mwachitsanzo, zitsulo zosapanga dzimbiri) kuti zitheke bwino |
Zochitika Zenizeni Zapadziko Lonse za Mipata Yogwira Ntchito
- Simenti Carbide Kuwalapazida zodulira (monga zobowola) ndi migodi—kumene kumatentha kwambiri.
- Zitsulo Excelsm'zigawo zomangika (monga mafelemu agalimoto, milatho) -pomwe kulimba ndi mphamvu zotsika mtengo ndizofunikira.
III. Minda Yofunsira
Kusiyanasiyana kwawo kumawapangitsa kukhala magawo osiyanasiyana:
(1) Mapulogalamu a Simenti a Carbide
- Zida Zodulira: Odula mphero, kubowola zitsulo (amagwirira kudula zitsulo zothamanga kwambiri).
- Kukumba/Kubowola: Malangizo obowola miyala, zida zoboola ngalande (imakana miyala yowononga).
- Zamlengalenga: Zida zolondola (monga, zida za turbine) zomwe zimafunikira kutentha / kusavala.
(2) Ntchito Zachitsulo
- Zomangamanga: Rebar, mizati (imadalira mphamvu + ductility kuti itetezeke).
- Zagalimoto: Chassis, magawo a injini (amalinganiza mphamvu, kulimba, ndi mtengo).
- General Machinery: Magiya, ma shafts (osinthasintha kudutsa kutsika mpaka kumtunda).
IV. Mitengo Yopangira & Kukonza
(1) Kuyerekeza Mtengo
- Simenti Carbide: Zokwera mtengo chifukwa:
- Zosowa zopangira (tungsten, cobalt).
- Complex ufa zitsulo (kukanikiza + sintering).
- Chitsulo: Ndiotsika mtengo chifukwa:
- Kuchuluka kwachitsulo/carbon.
- Kupanga kokhwima (kusungunula, kugudubuza).
(2) Kuvuta Kukonza
- Simenti Carbide: Zovuta ku makina-zimafunika EDM (makina otulutsa magetsi) kapena kudula laser.
- Chitsulo: Zosavuta kupanga—zopeka, zokugudubuza, kapena zodula ndi zida wamba.
V. Kodi kusankha?
Sankhani potengera:
- Chilengedwe:
- Kutentha kwakukulu / kuyabwa? → Carbide ya simenti.
- Zodabwitsa/zowopsa? → Chitsulo.
- Zofunikira Zochita:
- Kuuma kwambiri? → Carbide ya simenti.
- Ductility / kulimba? → Chitsulo.
- Bajeti:
- Ndizovuta? → Chitsulo.
- Kuchita kumalungamitsa premium? → Carbide ya simenti.
Kutsiliza: Sankhani Mwanzeru Pazosowa Zanu
Carbide yopangidwa ndi simenti ndi zitsulo sizopikisana—ndi zida zapadera. Gwiritsani ntchito carbide pazovuta kwambiri; dalira chitsulo kuti ukhale wamphamvu zosunthika, zotsika mtengo.
Muli ndi polojekiti? Gawani zosowa zanu mu ndemanga, ndipo tiyeni tikambirane za zinthu zabwino kwambiri zoyenera!
