Kodi mumadziwa bwanji za tungsten carbide strips?

Ziribe kanthu ngati mwagwiritsa ntchito tungsten carbide n'kupanga kapena ayi, koma ine ndikukhulupirira inu mukhoza kudziwa za tungsten carbide. Nthawi zambiri timatha kuwona zinthu za tungsten carbide m'moyo wathu. Mwachitsanzo, tikakwera basi, timatha kuona nyundo pafupi ndi zenera la basi, imeneyi ndi imene timagwiritsa ntchito kuthyola zenera kuti tithawe tikakumana ndi tsoka. Kawirikawiri, nyundo yamtunduwu idzapangidwa ndi tungsten carbide, chifukwa cha kuuma kwake kwakukulu. Ngati munazolowera kuvala wotchi, muwotchiyo mulinso alloy yolimba chifukwa chokana kuvala kwambiri......

Kulimba kwa simenti ya carbide ndi yachiwiri kwa diamondi yomwe ili ndi kukana kwambiri kuvala. Kodi mukudziwa chifukwa chake carbide ya simenti imakhala yolimba chonchi?

Chifukwa tungsten carbide ndi sintered metallurgical mankhwala a mawonekedwe ufa. Amapangidwa mu vacuum kapena ng'anjo yochepetsera haidrojeni yokhala ndi ufa wa Micron wa Tungsten (WC) monga chopangira chachikulu ndi Cobalt (Co), Nickel (Ni), kapena Molybdenum (Mo) monga chomangira.

Tungsten carbide sikuti imakhala ndi mawonekedwe olimba kwambiri komanso kukana kuvala kwambiri komanso kukana dzimbiri komanso kukhazikika kwamphamvu pansi pa kutentha kwakukulu (ngakhale pa 500 ºC imakhala yosasinthika ndipo pa 1000 ºC imakhala yolimba kwambiri)
Mizere ya tungsten carbide ili ndi mawonekedwe onse a tungsten carbide.





Kupanga ndondomeko ya tungsten carbide mizere
Mizere ya carbide imayimira makona anayi,amadziwikanso kuti ma flats a tungsten carbide. Amapangidwa kudzera ufa (makamaka WC ndi Co ufa monga pa chilinganizo) osakaniza, mpira mphero, kupopera nsanja kuyanika, extruding, kuyanika, sintering, (ndi kudula kapena akupera ngati n'koyenera) anayendera komaliza, kulongedza ndiye.kubweretsa, kuyang'ana kwapakati kumachitika pakatha njira iliyonse kuti muwonetsetse kuti zinthu zoyenerera zokha zitha kusunthidwa kunjira ina yopangira.

Kuwongolera Kwabwino kwa zingwe za tungsten carbide
The HRA tester, TRS tester, Metallographic microscope(Check microstructure), coercive force tester, cobalt magnetic tester amagwiritsidwa ntchito poyang'ana ndikuwonetsetsa kuti zinthu za carbide strip ndi zoyenerera bwino, kuonjezera apo, mayeso otsitsa amawonjezedwa makamaka pakuwunika kwa carbide onetsetsani kuti palibe cholakwika chilichonse pamzere wautali. Ndipo kuyendera kukula malinga ndi dongosolo.

Kugwiritsa ntchito tungsten carbide strips
Zomwe zili muzitsulo za WC ndi Co in tungsten carbide zogwiritsidwa ntchito mosiyanasiyana sizigwirizana, ndipo mawonekedwe ake ndi ambiri. Mzere wa Tungsten carbide umadziwika kuti ndi mtundu umodzi wa chida chodulira carbide. Ndi iti yomwe ili yoyenera kupangira matabwa olimba, bolodi lometa, ndi bolodi lapakatikati? Zingwe za simenti za carbide zitha kugwiritsidwa ntchito popanga zida zopangira matabwa, monga zida zopangira, zopumira, mpeni wa serrated, ndi masamba osiyanasiyana.

Sankhani giredi
Kuuma kumawonjezeka pamene cobalt imachepa ndipo
awiri a tungsten carbide particles amachepetsa. Mphamvu ya flexural imawonjezeka ngati
cobalt imawonjezeka ndipo kukula kwa tungsten carbide kumachepa.
Choncho, ndi sitepe yofunikira kwambiri kusankha kalasi yoyenera kwambiri malinga ndi
ntchito zosiyanasiyana, zida zosiyanasiyana zokonzedwa, ndi malo osiyanasiyana ogwirira ntchito.
Kusankha kolakwika kwamagiredi kumabweretsa zovuta monga kutsika, kusweka, kuvala kosavuta,
ndi moyo waufupi.

Pali magiredi ambiri oti musankhe

Kodi kusankha kalasi yoyenera mwamsanga?
Ngati simukudziwa kuti katundu wanu ndi wotani, TakulandilaniLumikizanani nafe.
