Ncej Forgings rau Hydraulic Turbines thiab Hydraulic Generators

1 Smelting

1.1 Alkaline hluav taws xob rauv smelting yuav tsum tau siv rau forging steel.

2 Forging

2.1 Kev txiav nyiaj txaus yuav tsum muaj nyob rau sab sauv thiab qis kawg ntawm cov hlau ingot kom ntseeg tau tias cov khoom forged tsis pub muaj cov kab noj hniav thiab kev sib cais hnyav.

2.2 Cov cuab yeej forging yuav tsum muaj peev xwm txaus los xyuas kom tiav forging thoob plaws hauv seem. Cov duab thiab qhov ntev ntawm lub forged piece yuav tsum zoo sib xws nrog cov kev xav tau ntawm cov khoom tiav. Lub axis ntawm daim forged yuav tsum zoo dua ua ke nrog qhov nruab nrab ntawm cov hlau ingot.

3 Kev kho cua sov

3.1 Tom qab forging, lub forged daim yuav tsum tau normalizing thiab tempering kho, thiab yog hais tias tsim nyog, quenching thiab tempering kev kho mob kom tau ib tug uniform qauv thiab cov khoom.

4 Vuam

4.1 Loj axial vuam yuav tsum tau nqa tawm tom qab kev ntsuas kev ua tau zoo ntawm cov khoom forged ua tau raws li qhov yuav tsum tau ua. Vuam electrodes nrog cov khoom sib npaug rau cov khoom forged yuav tsum tau siv, thiab qhov zoo tshaj plaws vuam specifications yuav tsum tau xaiv rau cov txheej txheem vuam.

5 Kev Xav Tau

5.1 Kev tshuaj xyuas tshuaj yuav tsum tau ua rau txhua pawg ntawm cov hlau molten, thiab cov txiaj ntsig kev soj ntsuam yuav tsum ua raws li cov lus qhia tshwj xeeb.

5.2 Tom qab kev kho cua sov, axial mechanical zog ntawm lub forged piece yuav tsum tau raws li cov specifications. Yog tias xav tau los ntawm tus neeg siv khoom, kev sim ntxiv xws li kev khoov txias, shearing, thiab nil-ductility hloov pauv tuaj yeem ua tau.

5.3 Qhov saum npoo ntawm daim forged yuav tsum tsis pub muaj cov kab nrib pleb, folds, thiab lwm yam tsis xws luag uas cuam tshuam rau kev siv. Cov teeb meem hauv zos tuaj yeem raug tshem tawm, tab sis qhov tob ntawm kev tshem tawm yuav tsum tsis pub tshaj 75% ntawm cov nyiaj siv ua haujlwm.

5.4 Lub hauv paus qhov ntawm lub forged daim yuav tsum tau soj ntsuam pom los yog siv ib tug boroscope, thiab cov kev soj ntsuam xyuas yuav tsum ua raws li cov specifications.

5.5 Ultrasonic xeem yuav tsum tau ua nyob rau hauv lub cev thiab welds ntawm forged daim.

5.6 Magnetic particle soj ntsuam yuav tsum tau ua nyob rau hauv forged daim tom qab lub kawg machining, thiab cov kev lees txais yuav tsum ua raws li cov specifications.
