1. Yuav ua li cas txias - dov coils feem ntau muab qhab nia? Dab tsi yog qhov tseem ceeb ntawm cov qib sib txawv?
A: Nyob rau hauv kev lag luam xyaum, txias- dov coil qib zoo yog feem ntau muab faib ua peb pawg, nrog rau cov khoom tsim nyog ntxiv subdivided:
Cov Khoom Siv Tsim Nyog: Cov khoom lag luam uas ua tau raws li txhua yam kev cai. Raws li qhov zoo ntawm qhov chaw, lawv feem ntau muab faib ua pawg I thiab Pab Pawg II.
Usable Products: Cov khoom muaj qee yam tsis xws luag tab sis tseem siv tau hauv cov ntawv thov tsawg dua.
Cov khoom pov tseg: Cov khoom lag luam muaj qhov tsis zoo uas cuam tshuam rau kev siv tau zoo thiab tsis tuaj yeem muag lossis siv tau ib txwm.
2. Cov txheej txheem tseem ceeb rau kev txiav txim siab qib yog dab tsi? Los ntawm qhov ntev npaum li cas nws tuaj yeem ntsuas tau sai?
A: Kev txiav txim siab ceev ceev yuav tsum muaj kev ntsuam xyuas zoo raws li peb qhov tseem ceeb hauv qab no:
Surface Quality: Qhov no yog qhov taw qhia tseem ceeb tshaj plaws. Nws yog ib qho tsim nyog los xyuas seb cov hlau phaj saum npoo yog tiaj tus thiab du, thiab seb puas muaj qhov tsis xws luag xws li tawg, khawb, pitting, xeb, oxide nplai, los yog scale buildup. Thaum txiav txim siab qib, tus yuam sij yog saib ntawm hom, qhov loj me, thiab qhov ntom ntom ntawm qhov tsis xws luag, vim cov no suav nrog txiav txim siab qib kawg.
Dimensional Tolerances: Txias-rolled coils muaj qhov raug siab heev; thickness yuam kev yog feem ntau Tsawg dua los yog sib npaug rau ± 0.03mm. Txhua qhov sib txawv ntawm qhov sib txawv sab nraud ntawm qhov kam rau ua, xws li qhov tsis sib xws, camber, lossis tapering, yuav ua rau txo qis.
Mechanical Properties thiab Chemical Composition: Qhov no suav nrog cov ntsuas ntsuas xws li lub zog tawm los, lub zog tensile, thiab elongation, nrog rau cov ntsiab lus ntawm cov ntsiab lus xws li carbon, silicon, thiab manganese. Yog tias cov khoom siv sab hauv no tsis ua raws li cov qauv, cov khoom yuav raug txiav txim ncaj qha raws li tsis tsim nyog.
3. Dab tsi yog qhov tshwj xeeb zam rau qhov tsis xws luag rau cov qib sib txawv ntawm cov txias txias-rolled coils?
A: Qhov no yog tus qauv tseem ceeb uas yuav tsum tau tuav thaum txiav txim siab qib. Cov hauv qab no siv cov khoom lag luam ntawm Pawg I thiab Pab Pawg II ua piv txwv:
Qib|Qhov yuav tsum tau ua kom zoo|Ntug Kev Xav Tau Zoo|Tsis Zoo Length Tolerance
Pawg kuv|Qhov saum npoo raug tso cai kom muaj qhov khawb ntawm tus kheej, dents, indentations, thiab lwm yam, nrog rau qhov tob lossis qhov siab tsis tshaj 1/4 ntawm lub thickness kam rau ua.|Ntug raug tso cai kom muaj cov kab nrib pleb lossis cov npoo npoo tsis tshaj 1 hli.|Qhov tsis zoo Tsawg dua lossis sib npaug li 1%
Pawg II|Nto yog tso cai rau qee zaus muaj cov khawb me me, dents, indentations, pores, thiab lwm yam, tsis pub tshaj 1/2 ntawm lub thickness kam rau ua.|Ntug raug tso cai kom muaj cov kab nrib pleb lossis cov npoo npoo tsis tshaj 1 hli.|Kev puas tsuaj tsawg dua lossis sib npaug li 5%
Khoom siv|Thaum cov khoom tsis raug tso cai rau 5% txog 20% ntawm tag nrho qhov ntev ntawm lub kauj, nws tuaj yeem txiav txim tau raws li cov khoom siv tau - 5% qhov tsis zoo
4. Dab tsi yog qee qhov kev ntsuam xyuas ceev uas siv txoj kev "saib, ntsuas, thiab ntsuas" ntawm qhov chaw txais?
A: Thaum tau txais cov khoom, koj tuaj yeem siv cov hauv qab no "saib, ntsuas, thiab ntsuas" cov kauj ruam rau kev ntsuas ceev:
Saib (Saib qhov chaw): Hauv qhov dej -lit ib puag ncig, ua tib zoo tshuaj xyuas qhov chaw ntawm cov hlau kauj. Them tshwj xeeb rau:
Tej yam tsis xws luag: xws li nplai, delamination, lossis indented hlau oxide nplai.
Txhua qhov khawb: Qhov no yog ib qho teeb meem tshwm sim. Ua tib zoo saib xyuas qhov kawg ntawm cov hlau kauj, vim tias kev tuav tsis raug thaum lub sij hawm thauj mus los yuav yooj yim ua rau cov npoo.
Kev ntsuas thib ob (Dimensional Measurement):
Thickness: Siv lub micrometer los ntsuas ntau zaus ntawm qhov chaw sib txawv raws qhov dav ntawm cov hlau kauj kom ntseeg tau tias nws nyob rau hauv qhov siab. Lub thickness kam rau ua ntawm siab -zoo txias-rolled coils yuav tsum nruj me ntsis tswj nyob rau hauv ± 0.03mm.
Cov tsos mob: Saib xyuas seb cov hlau coil nthuav tawm cov duab tapered (tapering Ntau dua lossis sib npaug ntawm 30mm yog qhov tsis tsim nyog), cov npoo dhau (Ntau dua lossis sib npaug li 5 hli yog qhov tsis lees txais), lossis camber. Cov no yog cov qauv tsim nyog rau kev txiav txim siab qib.
Kev Xeem Thib Peb (Kev Xeem Ua Haujlwm Yooj Yim):
Spark Identification: Sib tsoo cov khoom nrog lub kaum sab xis grinder thiab ua raws li lub txim taws. Tsawg- carbon steel muaj cov kab hluav taws xob ntev dua thiab pom tseeb tawg thiab forking.
Xav/Suab: Ua ntaub ntawv saum npoo los yog coj mus rhaub nws maj mam nrog ib yam khoom nyuaj. Qhov kev xav thiab lub nkig ntawm lub suab tuaj yeem txiav txim siab seb cov khoom siv hardness zoo li cas.
5. Yuav ua li cas qib - cov nqe lus hais txog yuav tsum tau teev nyob rau hauv daim ntawv cog lus yuav khoom los tiv thaiv ib tug txoj cai?
A: Daim ntawv cog lus yog qhov tseem ceeb rau kev tiv thaiv cov cai. Thaum kos npe rau daim ntawv cog lus, cov nqe lus hauv qab no yuav tsum tau txhais kom meej:
** Qhia meej meej Cov Qauv Qib:** Daim ntawv cog lus yuav tsum tau qhia meej txog qib uas yuav tsum tau ua kom txias txias -rolled coils, xws li Pab Pawg I, thiab qhia txog cov qauv hauv lub tebchaws (xws li GB/T 3280) lossis cov qauv kev lag luam. Qhov no tuaj yeem tiv thaiv cov neeg xa khoom los ntawm kev xa tawm Pab Pawg II lossis txawm tias cov khoom siv tau.
** Pom zoo rau Lub Sijhawm Txais thiab Tsis Pom Zoo:** Qhia meej meej tias tus neeg yuav khoom muaj cai ua qib rov qab- tshuaj xyuas thaum tuaj txog. Teem lub sij hawm tsis txaus siab (piv txwv li, 15 lossis 30 hnub) thaum muaj teeb meem nrhiav pom thiab sau ntawv tsis pom zoo tuaj yeem raug tsa.
**Standardize Liability for Breach of Contract:** Cov txheej txheem tuav rau qhov tsis sib xws hauv qib ntawm cov khoom yuav tsum tau teev meej meej. Piv txwv li, yog tias cov khoom tau txais yog Pab Pawg II lossis siv tau, kev sib hais haum tuaj yeem ua raws li tus nqi luv nqi ntawm daim ntawv cog lus; yog tias nws muaj teeb meem, cov khoom yuav tsum tau xa rov qab thiab tag nrho cov kev poob uas tshwm sim yuav tsum tau them rov qab.
Kev tuav pov hwm txoj cai them nyiaj: Nws tuaj yeem teev tseg hauv daim ntawv cog lus tias ib feem ntawm cov nyiaj them yuav raug khaws cia raws li kev lees paub zoo ua ntej tshaj tawm thib peb -toj xeem tsab ntawv tshaj tawm thiab lees paub tias qib tsim nyog.
