Cov raj plaub fabyog ib hom hlau uas feem ntau siv rau hauv cov teb xws li cov qauv, tshuab thiab kev tsim kho. Thaum lub sijhawm tsim khoom, nws yog ib qho tsim nyog yuav tsum tau them sai sai rau ntau yam txheej txheem thiab kev tswj xyuas zoo. Yuav kom ntseeg tau tias cov raj plaub fab ua haujlwm tau zoo thiab zoo, cov kev ceev faj hauv cov txheej txheem tsim khoom tseem ceeb heev. Cov hauv qab no yog cov kev ceev faj tseem ceeb rau kev tsim cov raj plaub fab:
cov raj plaub fab thiab cov raj plaub fab
1. Kev xaiv thiab kev tshuaj xyuas cov khoom siv raw
Qhov zoo ntawm cov hlau: Cov khoom siv tseem ceeb ntawm cov raj plaub fab yog cov hlau kub dov lossis cov hlau txias dov. Cov hlau zoo uas ua tau raws li cov qauv hauv tebchaws lossis cov qauv kev lag luam yuav tsum tau xaiv kom ntseeg tau tias nws muaj cov khoom siv kho tshuab zoo thiab ductility. Cov tshuaj lom neeg sib xyaw, lub zog tensile thiab lub zog tawm ntawm cov khoom siv raw yuav tsum tau kuaj xyuas nruj me ntsis.
Kev tshuaj xyuas qhov zoo ntawm qhov chaw: Yuav tsum tsis muaj qhov tsis zoo ntawm qhov chaw ntawm cov hlau, xws li tawg, npuas, xeb, thiab lwm yam. Qhov zoo ntawm qhov chaw ntawm cov khoom siv raw cuam tshuam ncaj qha rau cov txiaj ntsig ntawm cov txheej txheem tom ntej xws li vuam thiab txheej.
2. Cov txheej txheem khoov txias
Kev tswj qhov khoov vojvoog: Hauv kev tsim cov raj plaub fab, kev khoov txias yog ib kauj ruam tseem ceeb. Cov hlau yuav tsum tau khoov ua ib lub plaub fab lossis lub duab plaub fab hauv qab qee qhov kev nyuaj siab. Lub vojvoog khoov yuav tsum tau tswj thaum lub sijhawm khoov kom tsis txhob muaj kev hloov pauv ntau dhau, uas yuav ua rau muaj kev tawg lossis lwj hauv phab ntsa raj.
Kev dov qhov tseeb: Thaum lub sijhawm dov, yuav tsum xyuas kom meej tias qhov tseeb ntawm kev dov kom ntseeg tau tias lub raj plaub fab ruaj khov thiab zoo ib yam. Kev hloov pauv ntau dhau yuav ua rau lub raj plaub fab nyuaj rau sib sau ua ke hauv kev ua tom ntej, lossis txawm tias siv tsis tau ib txwm.

3. Cov txheej txheem vuam thiab kev tswj hwm
Kev xaiv txoj kev vuam: Kev vuam zaus siab lossis kev vuam siv roj tsis siv neeg (MAG vuam) feem ntau yog siv rau hauv kev tsim cov raj plaub fab. Thaum lub sijhawm vuam, kev tswj hwm qhov kub thiab tam sim no ntawm kev vuam yog qhov tseem ceeb. Qhov kub siab dhau yuav ua rau cov khoom kub dhau, deform lossis hlawv, thaum qhov kub qis dhau yuav ua rau kev vuam tsis ruaj khov.
Kev tswj xyuas qhov zoo ntawm kev vuam: Thaum lub sijhawm vuam, yuav tsum tswj qhov dav, qhov tob thiab qhov ceev ntawm kev vuam kom ntseeg tau tias qhov sib koom ua ke vuam ruaj khov. Yuav tsum tau kuaj xyuas qhov vuam ntawm lub raj plaub fab tom qab vuam. Cov txheej txheem tshuaj xyuas feem ntau suav nrog kev tshuaj xyuas pom, kev tshuaj xyuas ultrasonic thiab kev tshuaj xyuas X-ray.
Kev tso tawm ntawm kev ntxhov siab ntawm kev vuam: Kev ntxhov siab thermal yuav tsim tawm thaum lub sijhawm vuam, uas yuav yooj yim ua rau lub raj square deform. Yog li ntawd, kev kho cua sov lossis kev ncaj yog qhov yuav tsum tau ua tom qab vuam kom txo qhov kev ntxhov siab sab hauv thiab xyuas kom meej qhov ruaj khov ntawm cov duab geometric ntawm cov yeeb nkab.
4. Ncaj thiab ua kom zoo nkauj
Cov txheej txheem ncaj: Lub raj plaub fab tom qab vuam yuav raug warped lossis deformed, yog li nws yuav tsum tau ncaj los ntawm lub tshuab ncaj. Cov txheej txheem ncaj yuav tsum tau tswj hwm lub zog ncaj kom tsis txhob khoov lossis deformation ntau dhau.
Kev ua kom raug: Thaum lub sijhawm ua kom ncaj, lub kaum sab xis, qhov ncaj thiab qhov tiaj tiaj ntawm lub raj plaub fab yuav tsum tau ua kom tau raws li qhov yuav tsum tau tsim. Kev hloov pauv ntau dhau yuav cuam tshuam rau lub peev xwm thauj khoom thiab qhov tsos ntawm lub raj plaub fab.
5. Kev tswj qhov ntev thiab phab ntsa tuab
Qhov tseeb ntawm qhov ntev: Yuav tsum tswj qhov ntev, dav, thiab qhov siab ntawm lub raj plaub fab kom meej. Tej qhov sib txawv ntawm qhov ntev yuav cuam tshuam rau kev sib dhos lossis kev teeb tsa ntawm lub raj plaub fab. Thaum lub sijhawm tsim khoom, yuav tsum ntsuas thiab xyuas kom meej tias lub raj plaub fab ua tau raws li cov qauv tsim.
Kev sib npaug ntawm phab ntsa tuab: Lub phab ntsa tuab ntawm lub raj plaub fab yuav tsum tau khaws cia kom sib npaug thaum lub sijhawm tsim khoom. Kev hloov pauv ntawm phab ntsa tuab ntau dhau yuav cuam tshuam rau lub zog thiab lub peev xwm ntawm lub yeeb nkab, tshwj xeeb tshaj yog nyob rau hauv cov ntawv thov kev tsim kho nrog cov khoom hnyav. Kev kuaj qhov tuab ntawm phab ntsa feem ntau yog qhov yuav tsum tau ua ntej tawm hauv lub Hoobkas kom ntseeg tau tias ua raws li cov qauv.
6. Kev kho qhov chaw thiab tiv thaiv xeb
Kev Ntxuav Qhov Chaw: Tom qab tsim lub raj plaub fab, qhov chaw ntawm cov yeeb nkab yuav tsum tau ntxuav kom tshem tawm cov seem vuam slag, roj stains, xeb, thiab lwm yam. Ib qho chaw huv si yuav pab tau rau kev txheej tom ntej thiab kev kho tiv thaiv xeb.
Txheej tiv thaiv xeb: Yog tias lub raj plaub fab siv sab nraum zoov lossis hauv qhov chaw nyuaj, yuav tsum tau kho kom tiv thaiv xeb. Cov txheej txheem kho mob feem ntau suav nrog kev kub-dip galvanizing thiab txau cov txheej tiv thaiv xeb. Galvanizing tuaj yeem tiv thaiv xeb thiab ua kom lub neej ua haujlwm ntawm cov raj plaub fab ntev dua.
Kev tshuaj xyuas qhov zoo ntawm qhov chaw: Tom qab kev kho qhov chaw tiav lawm, yuav tsum tau tshuaj xyuas qhov tsis zoo ntawm qhov chaw xws li tawg, qhov ntswj, xeb, thiab lwm yam. Yog tias qhov tsis zoo tshwm sim ntawm qhov chaw, nws yuav cuam tshuam rau qhov tsos thiab kev siv tom qab.
7. Kev kho cua sov thiab cua txias
Kev Ua Kub: Rau qee cov hlau muaj zog siab, kev ua kub yuav tsum tau ua kom txo qhov nyuaj ntawm cov khoom, txhim kho nws cov yas, thiab zam kev tawg ntawm cov yeeb nkab vim qhov nyuaj ntawm cov khoom.
Kev tswj cua txias: Cov txheej txheem txias ntawm lub raj plaub fab yuav tsum tau tswj hwm qhov txias kom meej kom tiv thaiv kev ntxhov siab sab hauv thiab kev hloov pauv los ntawm kev txias sai lossis txias tsis sib xws.
8. Kev tshuaj xyuas thiab kev sim zoo
Kev tshuaj xyuas qhov loj thiab kev kam rau siab: Qhov loj sab nraud ntawm lub raj square yuav tsum tau kuaj xyuas tsis tu ncua thaum lub sijhawm tsim khoom kom ntseeg tau tias lawv ua tau raws li qhov yuav tsum tau tsim, suav nrog qhov ntev, dav, qhov siab, phab ntsa tuab, thiab lwm yam.
Kev ntsuam xyuas cov khoom siv kho tshuab: Cov khoom siv kho tshuab ntawm lub raj square raug sim los ntawm kev sim tensile, kev sim khoov, thiab lwm yam kom ntseeg tau tias nws lub zog, toughness thiab plasticity ua tau raws li cov qauv xav tau.
Kev kuaj pom qhov tsis zoo ntawm qhov chaw: Qhov chaw ntawm lub raj plaub fab yuav tsum tsis muaj qhov tsis zoo xws li kab nrib pleb, npuas, thiab qhov nkhaus. Kev tshuaj xyuas pom lossis kev sim ultrasonic feem ntau siv los xyuas kom meej tias qhov zoo ntawm lub raj ua tau raws li cov qauv.
Ntim thiab kev thauj mus los
Cov kev cai ntim khoom: Tom qab tsim khoom, lub raj plaub fab yuav tsum tau ntim kom zoo kom tiv thaiv kev puas tsuaj thaum thauj mus los. Cov roj ntim tiv thaiv xeb, cov thawv ntawv lossis cov ntoo pallets feem ntau yog siv rau kev ntim khoom.
Cov xwm txheej kev thauj mus los: Thaum lub sijhawm thauj mus los, tsis txhob sib tsoo lossis nias ntawm lub raj plaub fab thiab lwm yam khoom, thiab tsis txhob khawb, hloov pauv thiab lwm yam teeb meem ntawm qhov chaw ntawm lub raj. Tsis txhob raug rau cov huab cua noo ntev thaum lub sijhawm thauj mus los kom tiv thaiv kev xeb.
