1.What yog lub hauv paus ua rau muaj kev deormation?
Cov khoom siv cua sov: Qhov kub ntawm 450 degree ua rau muaj txiaj ntsig zoo ntawm cov hlau kom poob los ntawm 60%, thiab lub luj tshib unformation nyob rau hauv nws tus kheej qhov hnyav.
Zinc Immersion: Cov Kev Cuam Tshuam Hydrodynamic ntawm Cov Kua Zinc Ua Rau Qhov Tsis Txaus Ntseeg Hauv Thaj Chaw Nyias (xws li Phab Ntsa Nyias (xws li Sab Phab Ntsa)
Lub Caij Txias: Qhov sib txawv hauv thermal expansion coefficient ntawm zinc txheej thiab cov hlau substrate ua rau muaj kev ntxhov siab tsis zoo
Structural weaknesses: Small radius elbows with R=1.5D and long arm elbows (center distance>3D) yog tus muaj zog ntau rau distortion
2.Qhov cov txheej txheem daws teeb meem zoo li cas?
Prefabricated tus qauv hloov
Phab Ntsa Thickness Them Nyiaj: Ua kom cov phab ntsa tuab ntawm lub zog tsim tawm: Weld Tus Ntoo Cuam Tshuam Kev Txhawb Nqa Lub Sij Hawm Rau Ntawm Lub Luj Tshib (tshem tawm tom qab Galvanizing)
Galvanizing tooling optimization
Precision kub-lub sij hawm tswj
Kev Ua Tshuab
Hot shaping: Before the zinc layer is fully hardened (>300 degree), siv hydraulic laub qws + arc pwm kom kho lub ovality
Tswj tus qauv: ovrality tsawg dua los yog sib npaug rau 1.5% dn
CARKING SELLECTION: Siv peb-cov menyuam lub tshuab muab tshuaj ncig ua rau cov khoom nruab nrab ntawm chav tsev kub.
3.How tuaj yeem siv tau thiab tsim qauv?
Ua Ntej Ntxiv
XAV Q345R hloov Q235 (tawm lub zog yog 30% siab dua) ntxiv micro-alloy cov nplej rau cov nplej kom zoo thiab txo cov khoom tawg
Kev txhim kho qauv
Zam kev siv ntev npab lauj tshib nrog ib qho chaw deb ntawm> 2.5d (siv ob 45 degree thrbows hloov)
Tus nqi deformation ntawm throbows nrog r ntau dua lossis sib npaug rau 2D yog qis dua li ntawm r =1. 5d
4.What yog qhov kev ntsuas zoo rau galvanizing tooling?
Tus Khoman Tshwj Xeeb: Siv qhov raug tshem tawm tshwj xeeb rau lub luj tshib deg thiab zinc kua nthab nyob rau ntawm 75 degree nkag lub kaum sab xis (txo qis kev cuam tshuam).
Teb Zinc Dipping: Tig ntawm qhov ceev nrawm ntawm {}} rpm thaum tab tom dipping kom ntseeg tau tias muaj kev sib tw ntawm cov zinc txheej (zam kev tsis sib xws thiab deformation).
V-shaped cooling rack: Place it on a 120 degree V-shaped graphite bracket immediately after leaving the zinc pot to limit radial shrinkage deformation.
5. Dab tsi yog cov qauv xeem?
Ovality: Laser 3D Scanning, Tunchance: Tsawg dua lossis sib npaug nrog 1. {Mm rau dn tsawg dua lossis sib npaug rau 80mm; Tsawg dua los yog sib npaug rau 2.5mm rau DN> 200mm.
Flatness: Flange nto yog sim nrog tiaj tiaj phaj + Hearteer Goosge, kev sib txawv tsawg dua lossis sib npaug}. 3mm \/ m.
Kev kho qhov tshwj xeeb: Kev kho cua kub hauv zos tsawg dua lossis sib npaug nrog 380 Qib Melting 419 Qib Siab), Zinc-nplua nuj), Zinc-nplua nuj) yuav tsum tau txau tom qab kho tau.
