Kev kho thiab kho
1. Cov txheej txheem txiav
Txoj kev:Laser, plasma, lossis oxygen - siv tau rau kev txiav roj. Waterjet txiavzoo dua yog tias xoom cua sov- thaj tsam cuam tshuam (HAZ) yuav tsum tau.
Preheating: For plate thicknesses >30𝑚𝑚, preheating rau 100 ° C - 150 ° Cua ntej thermal txiav yog pom zoo kom tiv thaiv ntug cracking.
Sib tsoo:Tom qab thermal txiav, cov npoo tawv yuav tsum yog hauv av rov qab (kwv yees . 1-2 hli) kom paub meej ductility rau tom ntej vuam los yog dabtsi yog khoov.
2. Vuam (Cov txheej txheem tseem ceeb)
S690QL1 yuav tsum tau tswj nruj kom tsis txhob muaj hydrogen-induced cracking (HIC) thiab grain coarsening.
Consumables:Siv qis-hydrogenfillers matching the strength level (eg, AWS A5.28 ER110S-G).
Thaum tshav kub kub input:Yuav tsum nruj me ntsis (feem ntau 10-25 kJ / cm). Kev siv hluav taws xob ntau dhau yuav ua rau cov nplua -cov qauv ua kom zoo, ua rau -60 ° C toughness ua tsis tiav.
Preheat & Interpass Kub:
Preheat: 75 ° C rau 150 ° Cnyob ntawm thickness.
Interpass: Yuav tsum tsis pub tshaj 225 ° Clos tswj cov khoom siv kho tshuab.
3. Cold forming (Bending)
Springback:Vim muaj lub zog muaj zog, S690QL1 nthuav tawm qhov tseem ceeb springback. Tshaj -bending yog tsim nyog.
Yam tsawg kawg Bending Radius:
Transverse mus rau dov kev taw qhia: 3 ×tuab.
Parallel rau dov kev taw qhia: 4 ×tuab.
Kev nyab xeeb:Tsis txhob sawv ntsug ntawm lub xovxwm nres thaum lub sijhawm khoov vim lub zog siab khaws cia hauv cov khoom siv.
4. Kev kho cua sov
Delivery condition:S690QL1 yog xa hauv quenched & Tempered (Q + T)xeev.
Kub tsim ceeb toom:Tsis txhob kub cov hlau saum 580 ° C. Tshaj qhov ntsuas kub no yuav ua rau poob ntawm lub zog thiab toughness mus tas li.
Stress Relieving:Yog tias xav tau, nws yuav tsum tau ua ntawm 530 ° C thiab 580 ° C.
5. Machining
Tooling:Siv cov khoom siv carbide-tippedlos yog siab -ceev cobalt steel.
Tswv yim:Tswj tus nqi pub noj tas li thiab siv siab -siab coolant los tiv thaiv kev ua haujlwm nyuaj.
