Ntawv Hlau Hlau Hardening: Cov Kev Siv thiab Kev Siv

Daim Ntawv Hlau yog cov khoom siv ntau yam siv hauv kev lag luam ntau yam, suav nrog Automotive, Aerospace, tsim kho, thiab kev tsim khoom. Thaum nws tau paub rau nws lub zog thiab lub zog, muaj ntau qhov uas muaj qhov nyuaj ntxiv yuav tsum txhim kho nws cov kev ua tau zoo. Cov ntawv no tshawb nrhiav cov txheej txheem ntawm cov ntawv tawv tawv hlau thiab lawv cov ntawv thov.

Taw qhia rau hlau hardening

Hlau tawv tawv yog cov txheej txheem uas nce lub hardness thiab lub zog ntawm cov hlau los ntawm kev hloov pauv nws lub cev. Qhov no tuaj yeem ua tiav los ntawm ntau cov txuj ci, xws li kev kho cua sov, cov kev kho deg, thiab ua haujlwm ua haujlwm. Lub hom phiaj tseem ceeb ntawm kev ua kom tawv yog txhawm rau txhim kho cov hlau tiv thaiv kom hnav, puas tsuaj, thiab deformation.

Cov Kev Sib Tw Ntawm Cov Ntawv Hlau Ntaus Hlau

1. Kev kho cua sov

Kev kho cua sov cuam tshuam nrog cua sov cov hlau rau ib qho ntsuas kub tshwj xeeb thiab tom qab ntawd txias nws ntawm tus nqi tswj hwm. Cov txheej txheem no tuaj yeem hloov cov hlau me me, ua rau muaj kev nyuaj siab thiab muaj zog ntxiv. Cov Kev Kho Tshav Kub Cua Sov muaj xws li:

- Annaling: Cov txheej txheem no cuam tshuam cua sov cov hlau rau qhov kub thiab txias thiab tom qab ntawd tso cai rau maj mam. Annealing tuaj yeem ua kom muaj kev ntxhov siab sab hauv, muag cov hlau, thiab txhim kho nws cov tshuab luam ntawv.
- Quenching thiab Tempering: Quenching cuam tshuam nrog sai sai txias txias txias lub rhaub dej kom ua tiav cov qauv qauv nyuaj. Tempering yog cov txheej txheem txuas ntxiv uas yuav rov ua kom rov qab ua rau cov hlau quenched los txo cov brittleness thiab txhim kho kev nruj.

2. Nto Kho

Cov txheej txheem kev kho deg kom pom tseeb rau kev hloov pauv cov khoom saum npoo ntawm cov hlau los txhim kho nws lub hardness thiab hnav tsis kam. Qee qhov kev kho mob tshwm sim muaj xws li:

- Nitrividing: Cov txheej txheem no cuam tshuam rau saum npoo ntawm cov hlau los ua cov nitrides, uas nce hardness thiab hnav tsis kam.
- Carburizing: carburizing cuam tshuam ntxiv carbon mus rau saum npoo ntawm cov hlau, tsim cov txheej txheem muaj pa roj carbon monoxide siab uas yog qhov nyuaj thiab hnav ntau dua.
- Laser tshav kub kub: Cov txheej txheem tshiab no siv ib qho kev siv laser kom ua kom sov ntawm cov hlau, ua rau muaj kev kub ntxhov sai thiab ua kom muaj qhov ua kom sov sai.

3. Kev Siv Tshuab Ua Haujlwm

Mechanical ua hauj lwm yuav deforming cov hlau kom nce nws lub hardness thiab lub zog. Qhov no tuaj yeem ua tiav los ntawm cov txheej txheem xws li:

- Rolling: Dov cuam tshuam nrog cov hlau ntawm cov txiv hmab kom txo nws cov thickness thiab nce nws lub zog.
- Forging: Forging cuam tshuam nrog cov hlau siv cov hlau compressive, uas tuaj yeem hloov kho nws cov khoom lag luam qoob loo.

Cov ntawv thov ntawm Hardened Sheet Hlau

Hardened sheet hlau nrhiav cov ntawv thov hauv ntau qhov kev lag luam vim nws cov khoom txhawb nqa. Qee cov ntawv thov muaj xws li:

- Kev lag luam automotive: Hardened sheet hlau yog siv nyob rau hauv kev tsim cov tsheb lub cev, cov khoom sib xyaw, thiab lwm qhov uas yuav tsum muaj zog thiab hnav tsis kam.
- Kev lag luam Aerospace: Hauv ib lub tshuab hluav taws xob, tawv tawv ntoo yog siv hauv kev tsim kho cov dav hlau tsim, tshuab, thiab lwm yam tseem ceeb.
- Kev tsim kho kev lag luam: Hardened sheet hlau yog siv nyob rau hauv lub cuab yeej siv ntawm lub tsev sib xyaw, xws li vov tsev, cladding, thiab cov qauv kev txhawb nqa.
- Kev lag luam tsim khoom: Hauv kev tsim khoom, tawv tawv hlau yog siv nyob rau hauv kev tsim cov tshuab, cov cuab yeej, thiab cov khoom siv uas yuav tsum tau ua haujlwm ntev thiab ntev.
