1. Cov khoom siv sib xyaw & cov khoom siv hauv paus
Spa - h (JIS G 3114)
Alloying: CU (0.25-0.55%), CR (0.40-1.50%), P (0.07-0.15%)
Tensile lub zog: 490-620 mpa
Paib lub zog: ntau dua los yog sib npaug rau 355 mpa
Txheej Txheej Txheej Txheej Hlau (piv txwv, SS400 / S235JR)
Carbon {- manganese steel (tsis muaj alloys tseem ceeb)
Lub zog tensile: 400-510 mpa
Paib lub zog: ntau dua los yog sib npaug rau 235 MPa
2. Kev ua kev sib piv ua tau zoo
(1) Machining & Txiav
| Kev ua | Spa - h | Zoo tib yam hlau |
|---|---|---|
| Tuam Kev Hnav | 15-20% Kev hnav sai (CR / CU HARDENS KHOOM) | Txheem Tuam Txheem Lub Neej |
| Txiav Ceev | Txo los ntawm 10% (pom zoo) | Tsis Muaj Kev Txiav Txim Siab Ceev |
| Ntug zoo | Burr tsim kev pheej hmoo (xav tau kev deburring) | Nqus Tsev Tshuab Ntxhua Khaub Ncaws |
Lus ntuas: SivCarbide cov cuab yeejThiab coolant rau spa - h.
(2) vuam
| Chaw ua uas tsis tau haus | Spa - h | Zoo tib yam hlau |
|---|---|---|
| Cov Hluav Taws Xob | Tsawg - hydrogen (piv txwv, JIS Z3211 YGW11) | Txheem E6013 lees txais |
| Preheat | 100–150°C (thickness >20mm) | Tsis tshua muaj |
| Post - weld | Kev ua kom qeeb kom txhob tsoo lub taub hau | Tsis muaj qhov tshwj xeeb |
Kev twv: Cov cua txias txias yuav txo corrosion tsis kam nyob rau hauv haz.
(3) Txoj Kev & Dabtsi Yog Khoov
| Kev ua | Spa - h | Zoo tib yam hlau |
|---|---|---|
| Tsawg kawg nkaus khoov vojvoog | 2.5 × tuab (vs . 1.5 × × rau cov hlau me me) | Hloov tau yooj yim |
| Caij nkoj nthuav dav | 10-15% Siab dua | Yooj yim los tswj |
| Ib tug anerting | Yuav tsum muaj rau cov duab nyuaj | Tsis tshua muaj |
Tsab ntawv: Spa - h's qis elongation (~22% vs. 25% +) kev txwv sib sib zog nqus.
(4) Kev Kho Mob saum npoo
| Kev ua | Spa - h | Zoo tib yam hlau |
|---|---|---|
| Ua ntej - kev kho | Sandblasting + Tshuaj Xyuas Kev Lom Zem (Rau MATINA Kev tswj) | Priming / Xim Yuav Tsum |
| Corrosion tiv thaiv | Tus kheej - tiv thaiv patina (tsis muaj xim) | Yuav tsum muaj cov txheej txheej (piv txwv li, zinc) |
Nqi Them Nqi: Spa -} h txuag tau 20-30% nyob ntev- sij tiam tu tab sis ntxiv 10-15% mus rau Fabrication nqi.
3. Tiag {- Kev Lag Luam Ntiaj Teb-} Offs
Spa - h zoo:
{{050+ xyoo tech Service lub neej hauv cov chaw muaj kev nyab xeeb
Tsis muaj kev pleev xim xav tau (eco - tus phooj ywg)
Aesthetic xeb tsos (Architecture)
Dog dig hlau zoo:
Txo Cov Ncauj Lus Fabrictor
Yooj Yim Rau Tshuab / Weld (Ceev Ntau Lawm)
Kev zam txim ntau ntxiv rau cov neeg ua haujlwm hauv cov neeg ua haujlwm
4. Kev Lag Luam Kev Lag Luam
Spa - h: Txuas hniav (piv txwv li, Heavber choj, UK), cov neeg ntug dej hiav txwv, Cov Cuab Yeej Tsim Kho
Zoo tib yam hlau: Nyob sab hauv tsev, tsis - corrosive ib puag ncig, cov qauv ib txwm muaj
