High quality tungsten carbide ozizira mutu fa fakitale

Cold heading die ndi chidindo choponderezedwa chomwe chimayikidwa pa makina osindikizira kuti azikhomerera, kupindika, kutambasula, ndi zina zotero.

Kufa kwa mutu wozizira kumakhala ndi kupondaponda kwakukulu ndipo pamwamba pake pamakhala pansi pamakhala kupsinjika kwakukulu.Zinthu zakufa zimafunikira kuti zikhale ndi mphamvu zambiri, zolimba komanso kukana kuvala.Pambuyo mankhwala kutentha, pamwamba wathutungsten carbide ozizira mutu kufaAyenera kukhala olimba kwambiri ndipo mtima uyenera kukhala wolimba bwino, kotero kuti pamwamba pakhale kupanikizika kwina komwe kungathe kuthetsa kupsinjika komwe kumachitika pamutu wozizira.Ikhoza kuchititsa imfa kukhala yaitali.

Kuti muwonjezere magwiridwe antchito amtundu wa tungsten carbide ozizira mutu, athu onsecarbide ozizira mutu kufazosasoweka zimazimitsidwa ndi kupsya mtima pambuyo pa sintering ndondomeko.Njira yozimitsa ndi kutenthetsa ndikutenthetsa zitsulo za sintered alloy mu ng'anjo yothamanga kwambiri yozimitsa mpweya kupitirira madigiri 1300 ndiyeno mofulumira komanso mwamphamvu kuziziziritsa ndikuziwotchanso kuti zipse.Pochita izi, kutentha kumakwera, kusungunuka kwa tungsten carbide mu cobalt kumawonjezeka, ndipo kutentha kumazizira kwambiri kotero kuti tungsten carbide yomwe imasungunuka mu gawo la cobalt sichimatuluka nthawi, ndipo zina kapena zonse zimasungidwa.Ndiye mtima kuthetsa quenching mkati kuuma.Mwa kuwongolera kuwonongeka ndi kubalalitsidwa kwa njira yokhazikika yokhazikika, kapangidwe kazitsulo ndi kapangidwe ka aloyi zimasinthidwa, ndipo magwiridwe antchito amayenda bwino.
