1. Vuam
Vuam yog cov txheej txheem tseem ceeb tshaj plaws. S890QL1 tuaj yeem welded siv txhua txoj hauv kev (MIG / MAG, MMA, SAW), tab sis kev tswj xyuas kom sov yog qhov yuav tsum tau ua.
Preheating: Yuav tsum tau tiv thaiv kom txhob txias tawg. Pom zoo kub yog 150-250 degree, nce mus rau 300℃rau thicknesses tshaj 30mm.
Cov Khoom Siv Filler: Siv qis-hydrogen electrodes (HD < 5 ml / 100 g) kom tsis txhob muaj hydrogen-induced cracking.
Thaum tshav kub kub input: txwv tshav kub input los tiv thaiv softening ntawm tshav kub- cuam tshuam cheeb tsam (HAZ). Thaum tshav kub kub tuaj yeem rhuav tshem cov qauv nplej uas tsim thaum lub sij hawm thawj tempering txheej txheem.
2. Txiav thiab sib sau
Thermal Cutting: Laser, plasma, thiab oxy- roj txiav yog txhua yam tsim nyog. Txhawm rau kom tsis txhob muaj ntug hardening, preheating yuav tsum tau ua ntej nplaim taws txiav.
Cold forming: S890QL1 muaj qhov khoov tau zoo txawm tias nws muaj zog. Standard yob los yog dawb dabtsi yog khoov machinery yuav siv tau.
Nco tseg:Xyuas kom lub vojvoog dabtsi yog khoov loj txaus (feem ntau tsawg kawg yog 3-4 npaug ntawm lub phaj tuab) kom tsis txhob ntog tawg.
3. Machining
Cov khoom siv tau tuaj yeem siv los siv cov cuab yeej txheem, txawm tias nws lub zog siab ua rau cov cuab yeej hnav.
Cov cuab yeej: High-Speed steel (HSS) los yog carbide-tipped cov cuab yeej raug pom zoo.
Kev ruaj ntseg: Siv cov tshuab nruj thiab ruaj ntseg workpieces kom txo qis kev vibrations, uas tuaj yeem ua rau kev ua haujlwm nyuaj lossis cov cuab yeej tawg.
4. Kev kho cua sov
Vim tias S890QL1 raug xa mus rau hauv lub xeev quenched thiab tempered, kev kho cua sov ntxiv (xws li kev ntxhov siab) feem ntau poob siab tshwj tsis yog tias tsim nyog kiag li.
Cov cua kub siab tshaj qhov qub tempering (feem ntau ~ 550-600 degree) yuav txo tau cov hlau yield zog thiab toughness.
Yog tias yuav tsum tau tshem tawm kev ntxhov siab rau qhov tseem ceeb, nws yuav tsum tau ua ntawm qhov kub thiab txias (piv txwv li, ~ 530-580 degree) nrog qeeb, tswj kom txias.
