Kodi masamba a carbide amapangidwa bwanji?
Masamba a Carbide ndi amtengo wapatali chifukwa cha kuuma kwawo kwapadera, kukana kusavala, komanso kuthekera kosunga kuthwa kwa nthawi yayitali, kuwapangitsa kukhala abwino podula zida zolimba.
Masamba a Carbide nthawi zambiri amapangidwa pogwiritsa ntchito njira yomwe imaphatikizapo sintering tungsten carbide ufa kukhala mawonekedwe olimba, kutsatiridwa ndi kupanga ndi kutsiriza tsamba. Nayi chithunzithunzi chatsatanetsatane cha momwe masamba a carbide amapangidwira nthawi zambiri:
1. Kukonzekera Zakuthupi
- Tungsten CarbideUfa: Zomwe zimagwiritsidwa ntchito pamasamba a carbide ndi tungsten carbide (WC), yomwe ndi yowuma komanso yolimba ya tungsten ndi kaboni. Mtundu wa ufa wa tungsten carbide umasakanizidwa ndi zitsulo zomangira, nthawi zambiri cobalt (Co), kuti zithandize ndi njira yopangira sintering.
- Kusakaniza Ufa: Tungsten carbide ufa ndi cobalt zimasakanikirana kuti zikhale zosakanikirana. The osakaniza bwino ankalamulira kuonetsetsa olondola zikuchokera kwa ankafuna tsamba kuuma ndi toughness.
2. Kukanikiza
- Kuumba: Kusakaniza kwa ufa kumayikidwa mu nkhungu kapena kufa ndikukanikizidwa mu mawonekedwe ophatikizika, omwe ndi mawonekedwe ovuta a tsamba. Izi zimachitidwa pansi pa kupanikizika kwakukulu mu njira yotchedwakuzizira kwa isostatic (CIP) or kukanikiza kwa uniaxial.
- Kuumba: Pa kukanikiza, tsamba lokhalokha limapangidwa, koma silinandiwe kapena kulimba. Makina osindikizira amathandiza kusakaniza ufa wosakaniza mu geometry yomwe mukufuna, monga mawonekedwe a chida chodulira kapena tsamba.
3. Sintering
- High-Kutentha Sintering: Pambuyo kukanikiza, tsamba limakhala ndi sintering. Izi zimaphatikizapo kutenthetsa mawonekedwe oponderezedwa mu ng'anjo yotentha kwambiri pakati pawo1,400°C ndi 1,600°C(2552 ° F mpaka 2912 ° F), zomwe zimapangitsa kuti tinthu tating'ono ting'onoting'ono tigwirizane ndikupanga chinthu cholimba, chowundana.
- Kuchotsa Binder: Panthawi ya sintering, cobalt binder imakonzedwanso. Zimathandiza kuti tinthu tating'onoting'ono ta carbide tigwirizane wina ndi mzake, koma pambuyo pa sintering, zimathandizanso kuti tsambalo likhale lolimba komanso lolimba.
- Kuziziritsa: Pambuyo pa sintering, tsambalo limakhazikika pang'onopang'ono pamalo olamulidwa kuti lisawonongeke kapena kusokoneza.
4. Kupera ndi Kuumba
- Kupera: Pambuyo pakuwotcha, tsamba la carbide nthawi zambiri limakhala lovuta kwambiri kapena losakhazikika, kotero limakhazikika pamiyeso yolondola pogwiritsa ntchito mawilo apadera opumira kapena makina opera. Gawo ili ndi lofunikira popanga nsonga yakuthwa ndikuwonetsetsa kuti tsambalo likukwaniritsa zofunikira.
- Kujambula ndi Kujambula: Kutengera kugwiritsa ntchito, tsambalo limatha kupangidwanso kapena kusinthidwa. Izi zingaphatikizepo kugaya ngodya zina pamphepete, kuyika zokutira, kapena kukonza geometry yonse ya tsamba.
5. Kumaliza Chithandizo
- Zotikira Pamwamba (Mwasankha): Masamba ena a carbide amalandira chithandizo chowonjezera, monga zokutira ndi zinthu monga titanium nitride (TiN), kuti alimbikitse kulimba, kukana kuvala, komanso kuchepetsa kukangana.
- Kupukutira: Kuti mupititse patsogolo magwiridwe antchito, tsambalo limatha kupukutidwa kuti likhale losalala, lomalizidwa lomwe limachepetsa kukangana ndikuwongolera kudula bwino.
6. Kuwongolera Ubwino ndi Kuyesa
- Kuyesa Kuuma: Kuuma kwa tsamba nthawi zambiri kumayesedwa kuti kuwonetsetse kuti ikukwaniritsa zofunikira, ndi mayeso wamba kuphatikiza kuyesa kuuma kwa Rockwell kapena Vickers.
- Dimensional Inspection: Kulondola ndikofunikira, kotero makulidwe a tsamba amawunikiridwa kuti atsimikizire kuti akukumana ndi kulolerana ndendende.
- Kuyesa Magwiridwe: Pazinthu zina, monga kudula kapena kudula, tsambalo likhoza kuyesedwa zenizeni kuti zitsimikizire kuti likugwira ntchito monga momwe amafunira.
HUAXIN CHEMENTED CARBIDE imapereka mipeni yamtengo wapatali ya tungsten carbide ndi masamba kwa makasitomala athu ochokera m'mafakitale osiyanasiyana padziko lonse lapansi. Zida zamasamba, kutalika kwa m'mphepete ndi mbiri, mankhwala ndi zokutira zitha kusinthidwa kuti zigwiritsidwe ntchito ndi zida zambiri zamafakitale
Mabalawa akadutsa macheke onse abwino, amakhala okonzeka kugwiritsidwa ntchito m'mafakitale osiyanasiyana, monga zitsulo, kulongedza, kapena ntchito zina zodulira komwe kukana kuvala kwakukulu ndi kuthwa ndikofunikira.
