KEV KHO KUB

Tom qab casting, cov khoom siv crusher hnav muaj cov kev ntxhov siab casting seem, cov qauv nplej ntxhib thiab cov qauv metallographic tsis zoo.Kev kho cua sov tsis hloov qhov loj me lossis qhov hnyav ntawm ib feem, nws tsuas yog hloov kho cov qauv hlau sab hauv xwb.

Cov Haujlwm Tseem Ceeb:

1. Txo qhov kev ntxhov siab seem ntawm cov khoom siv casting kom tiv thaiv kev tawg thiab chipping thaum ua haujlwm.
2. Sib npaug qhov nyuaj thiab qhov tawv: qhov chaw hnav-resistant ntxiv rau qhov cuam tshuam-resistant substrate tiv thaiv kev tawg.
3. Txhim kho cov qauv ntawm cov noob, tshem tawm cov carbides uas ua rau puas tsuaj thiab ua tiav cov khoom siv tag nrho.
4. Xyuas kom meej tias muaj kev ua tau zoo sib xws thoob plaws cov pawg.

Rau cov khoom siv hlau manganese siab:kev kho dej tawvtsim cov qauv austenite, muab cov khoom ua haujlwm zoo-tawv. Qhov saum npoo tawv thaum raug kev cuam tshuam rau kev tiv thaiv kev hnav zoo dua. Rau cov khoom siv hlau cam khwb cia chromium siab:quenching + low-tempering kubmuab kev tiv thaiv kev hnav siab thaum tso tawm kev ntxhov siab kom tsis txhob tawg.

Tsuas yog cov tshuaj lom neeg uas tsim nyog xwb tsis tuaj yeem lav qhov zoo ntawm cov khoom. Kev kho cua sov kom zoo yuav txiav txim siab lub neej ua haujlwm ntawm cov khoom siv hnav.
