Carburizing hlau

Sep 30, 2022

Lub cev muaj zog thiab lub plhaub tawv yog qhov xav tau ntawm cov khoom siv tawv tawv steel. Qhov kev sib xyaw ua ke ntawm cov khoom no muab kev hnav thiab qaug zog tiv thaiv rau ntawm qhov chaw, thiab cuam tshuam rau lub hauv paus. Nws yog ua tiav los ntawm carburizing qhov saum npoo ntawm cov khoom thiab ces txias thiab quenching ib feem. Carburized Cheebtsam muaj xws li gears ntawm txhua yam, camshafts, universal pob qij txha, tsav pinions, linkage Cheebtsam, shafts thiab shafts. Tag nrho cov khoom no yuav tsum tiv taus hnav thiab qaug zog, muaj qhov toughness, thiab machinable.


Tej daim ntawv thov yog


Kev Thauj Mus Los: Cov khoom siv tawv tawv yog qhov tsim nyog hauv txhua lub tsheb uas muaj lub cev muaj zog, txawm tias nws yog lub tsheb me, lub tsheb sib tw, tsheb thauj khoom lossis lub nkoj.

Lub Hwj Chim Loj: Cov sprockets loj thiab cov khoom yuav tsum tau tiv thaiv kev ntxhov siab thiab hnav hauv cov chaw tsim hluav taws xob hydroelectric, cua turbine generators, drilling rig propeller drives, thiab cua turbine gears.

General mechanical engineering: General mechanical engineering: Daim ntawv thov hauv daim teb no suav nrog forging presses, hlau dov khoom, tshuab cuab yeej; cov cuab yeej siv mining tsav cov kab thiab kev sib kis hnyav; Lub ntiaj teb txav cov cuab yeej thiab cov dej num hnyav siv cranes. Hnav tsis kam thiab kev qaug zog zoo yog ib txwm muaj cov yam ntxwv tseem ceeb ntawm cov rooj plaub-hardened steels siv rau cov ntawv thov no.
