1. Vuam
Vuam yog cov txheej txheem tseem ceeb tshaj plaws. Cov cua kub ntau dhau tuaj yeem ua rau cov cua sov- cuam tshuam thaj chaw (HAZ), txo cov hlau thauj khoom- cov kabmob muaj peev xwm.
Cov txheej txheem: Haum rau MAG (GMAW), SMAW (stick), thiab SAW (submerged arc).
Preheating: Feem ntau pom zoo rau ntawm 80 ° C mus rau 150 ° C rau cov ntu tuab kom tiv thaiv qhov txias txias. Cov phaj tshaj 50mm yuav xav tau preheating thoob plaws tag nrho cov tuab.
Thaum tshav kub kub input: yuav tsum nruj me ntsis txwv (feem ntau <1.0 kJ/mm) kom tsis txhob degrading cov nplua -grained martensite-bainite qauv.
Consumables: Siv cov ntaub ntawv muab tub lim nrog cov ntsiab lus hydrogen tsawg. Cov kev xaiv muaj xws li "nyob rau hauv-match" fillers (lub zog qis dua lub hauv paus hlau) los txhim kho kev sib koom ua ke thiab txo qhov kev pheej hmoo tawg.
2. Txiav
Thermal cutting method yog tus qauv, tab sis lawv tsim kom muaj cua sov- thaj tsam cuam tshuam uas yuav xav tau kev npaj ntug.
Txoj kev: Laser txiav yog nyiam rau siab precision thiab tsawg thermal distortion. Plasma thiab Oxy- roj (nplaim) txiav yog siv rau cov phaj tuab, txawm tias oxy- roj ua rau HAZ loj tshaj plaws.
Ntug Zoo: Cov npoo ntawm cov cua kub yuav tsum tau deburred los yog sib npaug ntawm kev sib tsoo ua ntej ua haujlwm tom ntej xws li khoov kom tsis txhob pib tawg.
3. Kev tsim thiab khoov
S960QL muaj qhov txias txias zoo -formability txawm tias nws cov hardness siab.
Yam tsawg kawg nkaus Khoov Radius: Siab- lub zog steel yuav tsum muaj radii loj dua li cov hlau me me kom tsis txhob tawg. Cov lus qhia dav dav yog r=1.5 txog 2.5 npaug ntawm cov phaj tuab, txawm hais tias cov chaw tsim khoom tshwj xeeb tau lees paub (xws li Strenx® Class B) tuaj yeem tso cai khoov kom nruj dua.
Kev taw qhia: Khoov perpendicular mus rau dov kev taw qhia yog pom zoo kom nruj radii.
4. Tom qab-Kev Kho Mob Fabrication
Kev kho cua sov: Tus qauv kev ntxhov siab-relieving ntawm qhov kub thiab txias feem ntau tsis pom zoo, vim nws tuaj yeem ua rau cov khoom siv hluav taws xob tsis zoo ntawm cov quenched - thiab - tempered steel.
Kev Npaj Nto: Cov txheej tiv thaiv (thaum pleev xim lossis galvanizing) yog qhov tseem ceeb rau kev tiv thaiv corrosion nyob rau hauv ib puag ncig hnyav.
Primary Industrial Applications

Dab tsi yog qhov ceev ntawm S960QL?
Qhov ceev ntawm S960QL yog kwv yees li 7.85 g / cm³, tib yam li cov pa roj carbon steels. Qhov no tso cai rau kev xam qhov hnyav kom raug rau kev tsim qauv, ua kom pom lub zog zoo - rau - qhov hnyav piv hauv cov haujlwm engineering.
Dab tsi yog daim ntawv thov ntawm S960QL?
S960QL feem ntau yog siv rau hauv cov khoom hnyav-cov khoom siv ua haujlwm: crane booms, mining machinery, offshore platforms, thiab siab - nce lub tsev steel qauv. Nws kuj haum rau hauv cov tsheb tub rog thiab cov hlab ntsha siab uas xav tau lub zog siab - rau - qhov hnyav piv.
S960QL puas xav tau preheating ua ntej vuam?
Yog lawm, preheating yog tsim nyog rau S960QL vuam. Qhov pom zoo preheating kub yog 80-150 ° C, nyob ntawm thickness. Preheating txo qhov cua txias, tiv thaiv kev tsim martensite thiab txias tawg hauv thaj tsam weld.
Dab tsi yog qhov cuam tshuam toughness ntawm S960QL?
S960QL muaj kev cuam tshuam zoo heev, feem ntau ≥ 40 J ntawm -20 ° C (Charpy V-notch test). Qhov no ua kom nws tiv taus cov pob txha tawg hauv qhov chaw qis qis, tsim nyog rau kev siv sab nraum zoov thiab sab nrauv.
Dab tsi yog qhov elongation ntawm kev tawg ntawm S960QL?
Nws qhov tsawg kawg nkaus elongation thaum so yog 10% (rau 16 hli thickness). Qhov ductility no ua kom cov hlau tuaj yeem deform me ntsis ua ntej tsis ua haujlwm, nqus lub zog thiab txhim kho kev nyab xeeb ntawm cov khoom hauv qhov kev npaj txhij txog.
Puas yog S960QL yog quenched thiab tempered steel?
Yog lawm, S960QL yog quenched thiab tempered (Q&T) steel. quenching heats nws mus rau qhov kub thiab txias ces txias sai heev; tempering reheats nws kom qis kub. Cov txheej txheem no tsim kom muaj zog, tawv microstructure rau hnyav - siv lub luag haujlwm.
S960QL puas tuaj yeem khoov?
Khoov S960QL yog ua tau nrog cov txheej txheem kom raug. Siv qeeb khoov ceev, preheat yog tias tuab tshaj 10 hli, thiab tuav lub vojvoog loj (≥3 × thickness) kom tsis txhob tawg. Tom qab- khoov khoov raug pom zoo.
Modulus ntawm elasticity ntawm S960QL yog dab tsi?
Nws modulus ntawm elasticity yog kwv yees li 206 GPa, ib yam li feem ntau cov qauv hlau. Tus nqi no yog siv rau hauv cov qauv tsim kev suav suav los kwv yees deformation nyob rau hauv kev thauj khoom, ua kom cov qauv kev ruaj ntseg thiab precision.
Dab tsi yog qhov siab tshaj plaws thickness ntawm S960QL muaj?
S960QL muaj nyob rau hauv thicknesses txog li 150 hli, nyob ntawm manufacturers. Cov phaj tuab tuaj yeem xav tau kev kho cua sov kom paub meej tias cov khoom siv sib xws ntawm tus ntoo khaub lig-section, kev sib ntsib ua haujlwm- cov kev cai tshwj xeeb.
