Mpira wa Tungsten Carbide wopanda kanthu

Mipira ya Tungsten carbide imakhala ndi kuuma kwakukulu komanso mphamvu zambiri. Kapangidwe kake ka aloyi ndi tungsten carbide WC ndi cobalt komanso imakhala ndi chitsulo chochepa, faifi tambala, ndi zitsulo zina. Imalimbana ndi asidi ndi alkali ndipo sichita dzimbiri. Ili ndi ntchito zambiri. Itha kugwiritsidwa ntchito ngati mpira wopangira ma bearings apamwamba kwambiri, zoyatsira nsomba za ndodo zophera nsomba, mavavu a mpira m'mapampu amafuta a petroleum valve, ndi kuyeza simenti ya carbide pazida zoyendera - mbali zosagwira ntchito za chida ndi makina ena olondola kwambiri okhala ndi simenti. zofunika.

Zambiri za simenti ya mpira wa carbide ndi izi:

Pali mitundu itatu ya mipira ya simenti ya carbide,

1. Mmodzi ndi mpira wa carbide wopanda kanthu womwe umatchedwanso unground carbide mpira, Mipirayi imapangidwa popanda kukonzedwa pambuyo pa sintering, ndipo pamwamba pake ndi yovuta ndipo sangagwiritsidwe ntchito mwachindunji kupanga makina olondola kapena zida zolondola. Kupatula apo, palinso 2 zosiyana za mpira wa carbide, wina ndi mpira wa carbide wokhala ndi gulu lozungulira, ndipo wina alibe gulu mozungulira.

2. Yachiwiri ndi mpira wa carbide pambuyo pa mphero ya mpira, ndipo mapeto ake apamwamba ndi apamwamba kuposa a mpira wa carbide opanda kanthu, omwe angagwiritsidwe ntchito kupanga zida zamakina, zida, ndi matupi a valve okhala ndi zofunikira zochepa.

3. Chachitatu ndi kupukuta mpira wa carbide. Mpira wopukutidwa wa tungsten wopangidwa ndi simenti wa carbide umakhala ndi njira zitatu zogaya movutikira, kugaya bwino, ndi kupukuta, ndipo kuuma kwake kumafika pagalasi. Itha kugwiritsidwa ntchito kupanga makina olondola, zida, ndi mita zomwe zimafunikira kufananitsa bwino kwambiri. Ndi kuuma kwapamwamba komanso mtengo wokwera kwambiri, mawonekedwe ake ogwiritsira ntchito amangokhala ndi zida zapamwamba, zolondola kwambiri.

Ngati muli ndi chidwi ndi zinthu za tungsten carbide ndipo mukufuna zambiri ndi zambiri, mutha KULUMIKIZANA NAFE pa lamya kapena makalata kumanzere, kapena TITUMIZANI MAIME pansi pa tsamba.
