Xam tus naj npawb ntawm cov meters ntawmXim -} coated steel coilsyog qhov teeb meem tseem ceeb hauv kev ua hlau thiab kev ua lag luam. Cia kuv qhia kuv cov txheej txheem xam, uas yog feem ntau ntawm kev hnyav, dav, thickness, thiab ntom.
Tus tseem ceeb muab cov mis suav yog:
METERS (m) {= phaus (kg) / [dav (m) × tuab (mg / mp / m³)]
Hauv qab no, Kuv mam piav qhia txhua qhov parameter thiab kev xam theem siab.
### 1. Cov ntsiab lus piav qhia ntawm cov tseem ceeb muab cov cim sib xyaw thiab cov tsis sib xws
Meters (m) {= phaus (kg) / [dav (m) × Therry × steel ceev (kg / m³)]
Txhawm rau kom muaj cov chav nyob sib xws, nws yog ib qho uas hloov tuab ntawm millimeters (hli) rau meters (m), lossis kho cov chav ntoj. Cov mis siv feem ntau yog:
Metres (m) {= hnyav (kg) / [dav (m) tuab (hli) × 7.85]
Lub ntsiab lus ntawm txhua qhov ntsuas hauv cov qauv:
Qhov hnyav: Qhov nyhav ntawm lub pre -}}} coated steel chev, hauv kilograms (kg). Qhov no yog qhov tseem ceeb tshaj plaws thiab yuav tsum yog qhov hnyav ntawm cov hlau strip tom qab txiav tawm lub coil cov tub ntxhais thiab cov khoom ntim. Lub "Luj nyhav" feem ntau yog qhia nyob rau ntawm lub kauj. Yog tias tsuas yog qhov hnyav tag nrho, nug tus xa khoom rau qhov hnyav ntawm cov tub ntxhais thiab rho tawm.
Dav: Qhov dav ntawm tus hlau chev, hauv metres (m). Piv txwv li, qhov dav ntawm 1000mm yuav tsum hloov dua siab tshiab txog 1.0m hauv kev suav.
Thickness: lub hauv paus tuab ntawm cov hlau sawb, hauv millimeters (hli). Thov nco tseg: Qhov tuab no tsis suav nrog cov tuab tuab ntawm lub ntej - txheej txheej (pleev xim txheej). ** Txawm hais tias cov txheej txheem ntxiv rau cov tuab me ntsis rau cov tuab tuab thiab qhov hnyav, kev lag luam txheem cov laij lej feem ntau siv cov tuab ntawm kev yooj yim thiab kom zam dhau kev sib cav. Kev yuav khoom thiab kev cog lus muag yuav kuj tseem hais kom meej tias suav kom meej raws li cov tuab tuab ntawm cov tuab tuab yuav tsum tau siv.
** Quav ntom: ** Lub ntom ntom ntawm cov hlau feem ntau yog li 7.85 g / cm³. Tus nqi no yog cov qauv kev lag luam.
** Hloov mus rau 7850 kg / m³. Txawm li cas los xij, cov mis "×
* Thickness (mm) hloov mus rau metres yog "tuab × 0.001"
* Ceev 7850 kg / mp
* Yog li ntawd, "Dav × (tuab × 0.001) × 7850" {} "}" tuab tuab tuab .85 "
### 2. Piv txwv li kev xam qib
Piv txwv koj muaj ib yob ntawm pre -} painted steel nrog cov ntaub ntawv hauv qab no:
* Ceeb toom hnyav: 5,000 kg
* Dav: 1.25 m (piv txwv li, 1250 hli)
* Substrate tuab: 0.5 hli
** Cov theem xam: **
Meters=5000 kg / [1.25 m × 0.5]
= 5000 / (1.25 × 0.5 × 7.85)
= 5000 / (4.90625)
≈ ** 1019.1 meterers **
Yog li ntawd, cov kauj no yog kwv yees li 1019 meters ntev.
### 3. Cov kev txiav txim siab tseem ceeb thiab kev cuam tshuam cov ntsiab lus
1. ** Substrate thickness yog tus yuam sij ": ib txwm siv cov txheej tuab ntawm cov tuab, tsis yog cov coated tuab. Cov coated thickness tuaj yeem sib txawv los ntawm 0.02-0.05mm. Siv tus nqi no yuav ua rau kev tsis txaus ntseeg ntawm lub ntsuas mis suav, uas tsis muaj qhov cuam tshuam rau tus yuav.
2. ** Qhov hnyav yuav tsum yog Net **: Tsis txhob siv cov phaus tag nrho suav nrog cov tub ntxhais rau cov kev suav, raws li qhov no yuav ua rau qhov tshwm sim.
3. ** Cov nyhuv coating **: Txawm hais tias cov qauv suav tsis quav ntsej cov txheej, nws ntxiv li ntawm 3% -5% rau qhov hnyav. Rau cov ntawv thov yuav tsum tau muaj tseeb heev li, tus nqi ceev tus nqi ntawm ** 7.87 ** lossis txawm tias raug txiav txim siab rau kev kwv yees lub cev. Txawm li cas los xij, qhov no yuav tsum muaj kev pom zoo ua ntej ntawm tus neeg yuav khoom thiab tus muag khoom.
4. ** Cov nyhuv thev naus laus zis **: ob qho tib si thickness thiab qhov hnyav muaj qhov tsis zoo thev taus. Theoretical suav tus naj npawb ntawm meters yog tus nqi zoo tagnrho; Tus naj npawb tiag tiag ntawm meters tej zaum yuav me ntsis ntxiv (yog tias cov tuab tuab dua (yog tias cov tuab tuab muaj qhov tsis txaus siab) lossis tsawg dua (yog tias qhov tuab me me).
Ntsiab lus:
Qhov tseeb tshaj plaws thiab cov txheej txheem thoob ntiaj teb suav nrog kev laij cov me me {{}} net × net subs subs subs subs subs subs subs subs 7.85). Ua raws li lub siab siv ntawm net luj thiab substrate tuab yog qhov tseem ceeb los ua kom tiav cov txiaj ntsig raug.
