1. Dab tsi yog "ultra-thin material"? Qhov twg yog nws feem ntau siv?
A: Hauv kev lag luam txias- dov coil, "ultra- cov khoom nyias" feem ntau yog hais txog cov lus qhia tshwj xeeb nrog lub thickness ntawm 0.5mm lossis tsawg dua, thaum lub thickness tag nrho ntawm txias -rolled coils yog 0.2-4mm.
Hom Thicknesses thiab Daim Ntawv Thov:
0.5mm: Siv dav hauv cov khoom siv hauv tsev, qhov cua ducts, cov thawv xa khoom, thiab lwm yam, xav tau yooj yim khoov thiab hnav.
0.3-0.4mm: Feem ntau pom muaj nyob rau hauv tsheb sab hauv qhov chaw, rooj tog hauv chaw ua haujlwm, thiab lwm yam kev siv uas yuav tsum muaj qhov sib npaug ntawm lub zog thiab qhov hnyav.
0.2mm thiab hauv qab no: Feem ntau yog siv rau hauv siab -precision electronic shielding npog, precision ntsuas vaj tse, lub zog tshiab roj teeb pob thav duab, thiab lwm yam kev txiav - ntug kev lag luam.
2. Vim li cas ultra- cov khoom siv hlau nyias kim dua? Yuav ua li cas los txiav txim seb tus nqi tsim nyog?
A: Vim muaj kev tsim khoom ntau dua thiab qis dua, cov lus qhia tshwj xeeb yog feem ntau nyob rau hauv cov khoom luv luv thiab hais kom tus nqi siab dua.
Piv txwv li, thaum pib lub Plaub Hlis 2026, lub teb chaws tus nqi nruab nrab ntawm 0.5 hli txias - dov steel kauj yog 3985 yuan / tuj, thaum tus nqi nruab nrab ntawm 1.0 hli yog 3798 yuan / ton, qhov sib txawv ntawm 187 yuan / tuj. Hauv qee lub khw hauv zos xws li Chengdu, tus nqi sib txawv ntawm 0.5mm thiab 1.0mm txawm tias ze rau 200 yuan / tuj.
Txhawm rau txiav txim siab yog tus nqi tsim nyog, peb yuav tsum xav txog:
Thickness: Nyob rau hauv kev ua lag luam, lub thinner lub specification, lub siab dua tus nqi tsev. Qhov no yog vim qhov yuav tsum tau muaj kev sib tw ntau dua, thiab cov kev xav tau ntawm cov khoom siv thiab cov txheej txheem kuj tseem siab dua.
Hom: Thawj-tier hom (xws li Panzhihua Hlau thiab Steel Group) tuaj yeem hais txog 4080 yuan / tuj rau 0.5 hli DC01 cov khoom, thaum lwm hom (xws li Liuzhou Iron thiab Steel Group thiab Jiuquan Iron thiab Steel Group) hais nyob ib ncig ntawm 4000 yuan / tuj rau tib lub ntsiab lus ntawm SPCC.
Khoom siv: High-cov ntaub ntawv qib siab siv rau siab-kawg stamping (xws li ST14) yog kwv yees li 330 yuan / ton kim dua li cov ntaub ntawv zoo tib yam ntawm tib yam specifications (SPCC/DC01).
3. Yuav ua li cas los soj ntsuam cov kev ua haujlwm tseem ceeb thaum yuav cov khoom siv ultra- nyias?
A: Kev ua tau zoo ntawm ultra- cov ntaub ntawv nyias ncaj qha txiav txim siab qhov ua tiav lossis tsis ua tiav ntawm kev ua haujlwm tom ntej. Cov nram qab no qhov ntev yuav tsum tau tsom rau thaum kuaj:
Dimensional Accuracy: Ultra- cov ntaub ntawv nyias yog cov rhiab heev rau thickness kam rau ua. Lub thickness kam rau ua ntawm cov khoom tsim nyog feem ntau yuav tsum tau tswj tsis pub dhau ± 0.02mm, thiab siab -kev ntsuas qhov tseeb txawm yuav tsum tau ntsuas qhov tseeb ntawm ± 0.001mm. Daim ntawv pov thawj zoo yuav tsum tau thov los ntawm tus neeg muag khoom thaum yuav khoom.
Surface Quality: Qhov saum npoo yuav tsum tsis muaj oxide scale, khawb, thiab flatness yuam kev Tsawg dua los yog sib npaug rau 0.05mm. Txhua qhov pom, xeb, lossis ntug burrs tuaj yeem ua rau wrinkling lossis tsis tiav vuam thaum lub sij hawm stamping.
Mechanical Properties: Rau qib DC01 / SPCC, xyuam xim rau nws cov khoom siv kho tshuab: yield zog yog kwv yees li 130-260MPa, thiab lub zog tensile nyob nruab nrab ntawm 270-410MPa. Kev ceeb toom tshwj xeeb: Thaum lub thickness yog<0.5mm, the upper limit of yield strength can be increased by 40N/mm². This is the tolerance given by the industry standard, and you should pay attention to it when purchasing.
4. Dab tsi yuav tsum tau ceev faj tshwj xeeb thaum khaws cia, thauj, thiab txais cov coils ultra-thin steel?
A: Vim tias lawv qhov tsis muaj zog thiab qhov cuam tshuam rau kev puas tsuaj, ultra-cov hlau nyias nyias yuav tsum muaj kev khaws cia, kev thauj mus los, thiab kev lees paub ntau dua li cov pa txias -rolled coils.
Kev Tiv Thaiv Kev Cia thiab Kev Thauj Mus Los: Txhawm rau tiv thaiv kev deformation lossis ntug kev puas tsuaj los ntawm lub siab, ultra- nyias steel coils yuav tsum tsis txhob muab tso rau siab dhau. Thaum lub sij hawm thauj mus los thiab hoisting, tshwj xeeb lifting slings yuav tsum tau siv; ncaj qha zawm nrog cov hlua hlau yog nruj me ntsis txwv tsis pub, vim qhov no tuaj yeem yooj yim ua rau tsis muaj kev cuam tshuam ntawm cov npoo ntawm cov coils.
Warehouse Txais: Thaum tuaj txog, tshawb xyuas lub ntim tam sim ntawd kom muaj kev ncaj ncees, ua tib zoo saib xyuas cov npoo thiab thawj ob peb kauj ruam kawg, vim tias cov no yog siab - thaj chaw muaj kev pheej hmoo rau kev thauj mus los. Nws raug nquahu kom siv lub laser thickness gauge rau thickness re- tshuaj xyuas yog tias ua tau.
Lub Sijhawm Pom Zoo: Kev tshuaj xyuas yuav tsum ua kom tiav nyob rau lub sijhawm teev tseg hauv daim ntawv cog lus. Yog tias pom muaj teeb meem, cov ntaub ntawv pov thawj (xws li cov duab thiab cov yeeb yaj kiab) yuav tsum tau khaws cia tam sim ntawd, thiab sau ntawv tsis txaus siab yuav tsum xa mus rau tus neeg muag khoom.
5. Yuav ua li cas thiaj nrhiav tau tus neeg muag khoom ntseeg siab ntawm ultra-cov ntawv nyias nyias?
A: Tus yuam sij rau kev nrhiav ib tus neeg muab kev ntseeg siab ntawm ultra- cov ntawv nyias nyias yog xaiv lub tuam txhab lag luam loj lossis tus neeg sawv cev uas muaj peev xwm ua thiab xa khoom.
Nyiam cov tuam txhab lag luam loj: Lawv feem ntau sawv cev rau ntau lub tshuab steel, muaj cov khoom lag luam txaus, thiab muaj ntau yam kev qhia tshwj xeeb. Piv txwv li, Shanghai Caojin Kev Lag Luam tshwj xeeb hauv cov khoom txias-kho cov khoom los ntawm steel mills xws li Baosteel thiab Ansteel, thiab tsis tu ncua khaws ntau yam tshwj xeeb suav nrog 0.5 hli, nrog qhov tsawg kawg nkaus kom muaj nuj nqis tsawg li 1 tuj.
Ua ntej cov neeg ua haujlwm nrog ntev -kev sib raug zoo nrog steel mills: Piv txwv li, Jinan Gangling Trading, raws li tus neeg sawv cev tseem ceeb rau Ansteel txias- dov nyias daim hlau, koom tes nrog cov mills loj xws li Baosteel thiab Shougang, ua kom pom nws lub peev xwm muaj zog.
Xav txog qhov muaj peev xwm ua haujlwm tau zoo: Ua ntej cov neeg muag khoom uas tuaj yeem muab ib qho - nres cov kev pabcuam xws li kev txiav, txiav, thiab xa khoom, xws li Shanghai Bashida Kev Lag Luam. Qhov no yuav cawm koj cov teeb meem ntawm kev ua tom ntej thiab logistics.
