Cov xwm txheej kev loj hlob ntawm kev lag luam hlau cored
Feem ntau ntawm cov pej xeem yog tshiab rau cored hlau, tab sis nws qhov zoo tau muaj ntau heev. Nws muaj lub koob npe zoo rau cov yas ua, cuam tshuam toughness thiab fluidity ntawm hlau. Tom ntej no, Kuv' ll muab koj cov kev qhia luv luv ntawm nws qhov kev ua tau zoo. Vam tias koj tuaj yeem nrhiav cov kev paub uas koj xav tau.
Cored xaim yog tsim rau kev txhim kho kom zoo dua cov hlau tsis huv thiab ntau hom hlau. Nws yog qhov tshwj xeeb los ntawm melting ncaj qha mus rau hlau tsis xeb hlau thiab cov khoom xa tawm. Nrog rau kev txhim kho kev lag luam tsim cov hlau, kev nce ntxiv ntawm kev ua tau zoo ntawm cov hlau tsis xeb hlau thiab cov kav hlau, kev txhim kho ntawm cov qib casting txuas ntxiv thiab kev txhim kho tsis tu ncua sab nraud ntawm cov tshuab ua kom zoo dua qub kev lag luam tau ua rau txoj kev txhim kho zoo ntawm kev tsim cov hlau.
Qhov xaim xaim xaim xaim xaim xaim noj hom, thiab qhov ntxiv nrawm tuaj yeem tsim tau raws li txoj kab uas hla ntawm xaim hlau xaim thiab cov nplaim hluav taws xob ntawm cov khoom siv hlau. Alloy hlau nrog lub tshuab xaim tshuab ntsug stabilizer kom nkag mus rau hauv hlau tsis muaj hlau lossis hlau, ua tiav qhov xav tau qhov tob, melting thiab nqa ntawm lub cev thiab tshuaj lom neeg cov tshuaj tiv thaiv, kom tsis txhob muaj cov khoom ntxiv nrog huab cua thiab cov tshuaj tiv thaiv ntawm cov slag, txhim kho cov paib , yog li ua tiav lub hom phiaj ntawm kev ua kom zoo nkauj thiab ua kom pov, kom hloov qhov kev sib ntxiv, qhov siab ntawm kev siv thiab qhov chaw, thiab txhim kho kev ua tau zoo ntawm cov hlau cam thiab cam khwb cia hlau. Cored hlau muaj qhov cuam tshuam zoo rau kev txo tus nqi ntawm cov cam khwb cia steel thiab txhim kho kev lag luam txiaj ntsig ntawm cov hlau cam.
Kev sib tw hauv kev lag luam cored hlau yuav nyob ruaj khov hauv Suav. Daim ntawv thov nyob rau hauv molten steel refining yog tus paub tab, thiab qhov ntau ntawm alloy cored hlau nyob rau hauv hlau thiab hlau kev lag luam yog qhov loj. Dab tsi ntawm txoj kev loj hlob yog qhov kev lag luam hlau xaim muaj kev paub? Cia' s ua tibzoo saib qhov no.
Piv nrog tshuaj spheroidizer thiab inoculant tuam ntxhab, kev ua lag luam yog feem ntau nruj heev nyob rau hauv ib puag ncig uas nyoos spheroidizer thiab inoculant ntau lawm cov khoom siv yog siv rau kev tsim cov alloy cored hlau hauv kev loj hlob sai ntawm cored hlau.
Rau qhov tsim kev lag luam dav dav, cov tub ntxhais cov xov hlau tshuab ua lub luag haujlwm tseem ceeb hauv kev tsim kho thev naus laus zis thiab kev hloov pauv tshiab. Nyob rau tib lub sijhawm, kev hloov zuj zus ntawm cov thev naus laus zis hauv kev lag luam hlau txuas nrawm dua kom tau raws li cov kev lag luam uas hloov pauv mus ntxiv thiab cov neeg xav tau.
Yuav luag txhua tus neeg siv khoom hauv kev lag luam hlau xaim yog qhov loj thiab nruab nrab kev lag luam xws li kev lag luam hlau thiab kev lag luam. Kev tsim nyog ntawm kev siv cov hlau hlau yog qhov tseem ceeb rau qhov zoo ntawm cov hlau thiab cov hlau. Daim ntawv thov ib puag ncig ntawm cov khoom noj hlau ntawm cov xov hlau cored tseem yog qhov nyuaj heev, uas ua rau kev ntseeg tau thiab ruaj khov ntawm cov khoom lag luam los ua ib qho ntawm cov teeb meem uas tib neeg mloog zoo.
