Dab tsi yog Qhov Cracking ntawm Hmoov Metallurgy Khoom?

Sij hawm: 2024-01-06

1. Inter-particle hloov:

Lub interparticle bonding yog thawj zaug tsim los ntawm cov yas deformation thiab hmoov thaiv cov lus tsa suab. Nyob rau hauv cov xwm txheej zoo tagnrho, cov txheej txheem densification yog bidirectional, symmetrical thiab synchronous, thiab tsis muaj interparticle hloov chaw. Kev hloov pauv tom qab cov txheej txheem densification Cov kev txav me ntsis tiv thaiv kev tsim cov ntawv cog lus ntawm cov khoom thiab tuaj yeem rhuav tshem cov ntawv cog lus uas tau tsim nyob rau hauv cov theem pib ntawm kev sib sau.

2, Siab tensile, shear quab yuam:

Nyob rau hauv lub xeev ntawm hmoov metallurgy, yog hais tias lub tensile quab yuam generated los ntawm sab nraud los yog sab hauv ntawm lub cev zoo li tus siab tshaj lub ntsuab lub zog ntawm lub cev zoo li tus nws tus kheej, cov kab nrib pleb yuav tshwm sim.

3. Cov khoom siv tsis raug:

Rau ntau yam, cov hmoov hlau siv cov tshuaj ntxiv. Piv txwv li, ntxiv cov roj nplua nyeem uas tsim nyog rau kev sib xyaw ua kom cov compressibility thiab txo qhov tso tawm quab yuam. Txawm li cas los xij, ntxiv cov roj nplua nyeem ntau dhau rau cov hmoov hlau sib xyaw ua ke inhibits kev tsim cov ntawv cog lus ntawm cov khoom thiab cov ntawv cog lus. Cov neeg ua hauj lwm, impurities thiab txawm tias cov huab cua seem tuaj yeem cuam tshuam tsis zoo rau kev tsim cov ntawv cog lus.

4. Thaum lub sij hawm txawv txav ntawm cov yas sib cais txoj kev tsim:

Cov khoom yuav dhau los ua cov yas deformation tsis tuaj yeem. Tsis tas li ntawd, cov yas deformation rov qab yuav tshwm sim. Tom qab qhov kawg tsim theem, qhov sib txuam siab yuav txo qis thiab nws thiaj li poob mus rau xoom thaum lub sij hawm demolding txheej txheem. Nyob rau lub sijhawm thaum lub zog tsim tawm, cov kev ntxhov siab compressive tso tawm. Lub cev zoo li tus embryo yuav dheev hloov los ntawm yas mus rau theem elastic. Yog tias qhov kev ntxhov siab sab hauv siab tshaj qhov txwv lub zog ntawm lub cev zoo li tus, cov kab nrib pleb yuav raug tsim.


UA NTEJ: Hmoov Metallurgy Bearings tau dav siv hauv kev lag luam khoom siv hauv tsev
