Kodi ma carbide amapangidwa bwanji?
Masamba a carbide ndi ofunika chifukwa cha kuuma kwawo kwapadera, kukana kuwonongeka, komanso kuthekera kwawo kusunga kuthwa kwa nthawi yayitali, zomwe zimapangitsa kuti akhale abwino kwambiri podula zinthu zolimba.
Masamba a carbide nthawi zambiri amapangidwa pogwiritsa ntchito njira yomwe imaphatikizapo kusungunula ufa wa tungsten carbide kukhala wolimba, kutsatiridwa ndi kupanga ndi kumaliza tsamba. Nayi chidule cha momwe masamba a carbide amapangira nthawi zambiri:
1. Kukonzekera Zinthu Zopangira
- Tungsten CarbideUfa: Chinthu chachikulu chomwe chimagwiritsidwa ntchito mu masamba a carbide ndi tungsten carbide (WC), yomwe ndi chosakaniza cholimba komanso cholimba cha tungsten ndi kaboni. Ufa wa tungsten carbide umasakanizidwa ndi chitsulo chomangira, nthawi zambiri cobalt (Co), kuti chithandize pa ntchito yochotsa zinthu zonyansa.
- Kusakaniza Ufa: Ufa wa tungsten carbide ndi cobalt zimasakanizidwa pamodzi kuti zikhale chisakanizo chofanana. Chisakanizocho chimayendetsedwa mosamala kuti zitsimikizire kuti tsamba lake ndi lolimba komanso lolimba.
2. Kukanikiza
- Kuumba: Ufa wosakaniza umayikidwa mu nkhungu kapena die ndikuupondereza kukhala wopapatiza, womwe ndi mawonekedwe ozungulira a tsamba. Izi nthawi zambiri zimachitika pansi pa kupanikizika kwakukulu mu njira yotchedwakukanikiza kozizira kwa isostatic (CIP) or kukanikiza kwa uniaxial.
- Kupanga: Mukakanikiza, mawonekedwe okhwima a tsamba amapangidwa, koma silinakhale lolimba mokwanira kapena lolimba. Chosindikiziracho chimathandiza kukanikiza ufa wosakaniza kuti ukhale wofanana ndi momwe ukufunira, monga mawonekedwe a chida chodulira kapena tsamba.
3. Kusakaniza
- Kuwotcha Kutentha Kwambiri: Mukakanikiza, tsamba limaphwanyidwa. Izi zimaphatikizapo kutenthetsa mawonekedwe okanikizidwa mu uvuni pa kutentha komwe nthawi zambiri kumakhala pakati pa1,400°C ndi 1,600°C(2552°F mpaka 2912°F), zomwe zimapangitsa kuti tinthu ta ufa tizilumikizana ndikupanga chinthu cholimba komanso chokhuthala.
- Kuchotsa Binder: Pa nthawi yothira, chogwirira cha cobalt chimakonzedwanso. Chimathandiza tinthu ta tungsten carbide kumamatirana, koma pambuyo pothira, chimathandizanso kupatsa tsambalo kulimba kwake komaliza.
- Kuziziritsa: Tsamba likatha kuuma, limaziziritsidwa pang'onopang'ono pamalo olamulidwa kuti lisasweke kapena kupotoka.
4. Kupera ndi Kupanga
- Kupera: Tsamba la carbide likatha kuphwanyika, nthawi zambiri limakhala lolimba kwambiri kapena losakhazikika, kotero limaphwanyidwa bwino pogwiritsa ntchito mawilo apadera okhwima kapena makina opukutira. Gawo ili ndi lofunikira popanga m'mphepete mwakuya ndikuwonetsetsa kuti tsambalo likukwaniritsa zofunikira.
- Kupanga ndi Kujambula Mbiri: Kutengera ndi momwe tsambalo likugwiritsidwira ntchito, tsambalo lingapangidwenso mawonekedwe enaake kapena kusinthidwa. Izi zitha kuphatikizapo kupukuta ma angles enaake m'mphepete mwa tsamba, kugwiritsa ntchito zokutira, kapena kukonza bwino mawonekedwe onse a tsambalo.
5. Kumaliza Mankhwala
- Zophimba Pamwamba (Zosankha)Masamba ena a carbide amalandira chithandizo china, monga zokutira zinthu monga titanium nitride (TiN), kuti awonjezere kuuma, kukana kuvala, komanso kuchepetsa kukangana.
- Kupukuta: Kuti muwonjezere magwiridwe antchito, tsambalo likhoza kupukutidwa kuti likhale losalala komanso lomalizidwa lomwe limachepetsa kukangana ndikuwonjezera luso lodula.
6. Kuwongolera Ubwino ndi Kuyesa
- Kuyesa Kuuma: Kulimba kwa tsamba nthawi zambiri kumayesedwa kuti zitsimikizire kuti likukwaniritsa zofunikira, ndi mayeso ofala kuphatikizapo mayeso a Rockwell kapena Vickers.
- Kuyang'anira MagawoKulondola n'kofunika kwambiri, kotero kukula kwa tsamba kumayesedwa kuti zitsimikizire kuti zikukwaniritsa zofunikira zenizeni.
- Kuyesa Magwiridwe Antchito: Pa ntchito zinazake, monga kudula kapena kudula, tsambalo lingayesedwe zenizeni kuti litsimikizire kuti likugwira ntchito monga momwe likufunira.
HUAXIN CENTED CARBIDE imapereka mipeni yapamwamba ya tungsten carbide ndi masamba kwa makasitomala athu ochokera m'mafakitale osiyanasiyana padziko lonse lapansi. Masamba amatha kukonzedwa kuti agwirizane ndi makina omwe amagwiritsidwa ntchito pafupifupi m'mafakitale aliwonse. Zipangizo za masamba, kutalika kwa m'mphepete ndi ma profiles, mankhwala ndi zokutira zitha kusinthidwa kuti zigwiritsidwe ntchito ndi zipangizo zambiri zamafakitale.
Masamba akamaliza kufufuza bwino, amakhala okonzeka kugwiritsidwa ntchito m'mafakitale osiyanasiyana, monga ntchito zachitsulo, kulongedza, kapena ntchito zina zodulira komwe kukana kuwonongeka kwambiri komanso kuthwa ndikofunikira.
