1. Nyob rau hauv cov khoom tseem ceeb ntawm cov tshuab ua liaj ua teb yog qhov txias- dov coils feem ntau siv?
Txias-rolled coils yog siv dav hauv cov tshuab ua liaj ua teb, suav nrog ntau qhov chaw xws li kis tau tus mob, cov tshuab conveyor, cov khoom siv hauv tsev, thiab sab nrauv. Hauv kev sib kis, txias- cov hlua khi, nrog rau lawv lub zog zoo heev thiab tawv, yog siv dav hauv lub taub hau tsav tshuab ntawm cov tshuab txiav thiab cov txiav ua tiav hauv cov noob, muaj peev xwm tiv taus cov khoom hnyav thiab tsis tshua muaj kev cuam tshuam thaum tiling, tseb, thiab sau qoob. Hauv cov tshuab conveyor, txias- dov steel strips yog siv los tsim cov helical blades ntawm cov ntsia hlau conveyors (tseem hu ua augers), siv los ua ke cov qoob loo los thauj cov khoom loj xws li nplej thiab noob. Hais txog cov txheej txheem thiab sab nrauv, txias- cov dov daim hlau tau hloov pauv kub- cov phaj dov hauv cov npog, cov ntawv hlau, thiab cov cab plhaub ntawm cov tsheb laij teb loj thiab cov khoom sib xyaw ua ke. Tsis tas li ntawd, txias-khoov hlau kuj yog siv dav hauv hnav-cov khoom tiv taus xws li cov ploughshares thiab cov hniav txiav.
2. Dab tsi yog qhov ua tau zoo ntawm txias- dov coils hauv cov tshuab ua liaj ua teb piv rau kub- dov steel?
Cov laj thawj tseem ceeb vim li cas txias -rolled coils yog maj mam hloov kub-rolled steel hauv kev ua liaj ua teb machinery teb yog cov hauv qab no qhov zoo: Ua ntej, superior nto zoo: Txias-rolled steel muaj ib tug du thiab tiaj tus, tsis muaj oxide nplai, nruj me ntsis qhov tseeb thiab thickness kam rau ua rau kev tswj, thiab ib tug ntau dua nto nto tiav, uas yog beneficial kev kho mob. Thib ob, cov khoom siv kho tshuab zoo dua: Cov txheej txheem txias dov tuaj yeem txhim kho cov txiaj ntsig zoo thiab cov tawv tawv ntawm cov hlau thaum tuav cov khoom zoo. Piv txwv li, ST14 txias- dov steel phaj siv hauv Sany cabs muaj lub zog tensile ntawm 320-420 MPa. Qhov thib peb, zoo heev formability: txias{10}}kub steel muaj zoo stamping, dabtsi yog khoov, thiab welding zog, ua rau nws haum rau manufacturing complex-zoo li tus machinery ua liaj ua teb npog thiab cov khoom siv. Plaub, lub cev nyhav: Cov txheej txheem txias dov tuaj yeem tsim cov ntaub ntawv nyias nyias muaj zog, txo qhov hnyav ntawm cov tshuab ua liaj ua teb thaum ua kom muaj zog, uas pab txuag lub zog thiab txo kev noj.
3. Dab tsi yog cov txheej txheem kev ua haujlwm tshwj xeeb rau txias -rolled coils siv hauv tshuab ua liaj ua teb?
Agricultural machinery ua haujlwm nyob rau hauv ib puag ncig hnyav, muab kev xav tau siab ntawm cov khoom siv hluav taws xob txias -rolled coils. Noj 440MPa txias- dov steel sawb siv nyob rau hauv kev sib xyaw tshuab nruas ua piv txwv, nws cov kev ua haujlwm tseem ceeb suav nrog: lub zog tawm los Ntau dua lossis sib npaug rau 350MPa, lub zog tensile Ntau dua lossis sib npaug 450MPa, thiab elongation tom qab tawg ntau dua lossis sib npaug li 27%. Cov khoom siv no siv cov pa roj carbon tsawg, qis- silicon, siab -manganese microalloyed muaj pes tsawg leeg nrog ntxiv niobium thiab titanium. Ua ke nrog cov txheej txheem tswj dov thiab cua txias thiab lub tswb nrov- hom txheej txheem annealing, steel strip lub microstructure feem ntau yog ferrite nrog dotted cementite, kom ntseeg tau tias muaj zog thiab tawv thaum tuav zoo khoov formability thiab weldability. Tsis tas li ntawd, cov hniav siv rau kev txiav cov qoob loo (xws li cov qab zib thiab cov zaub mov) yuav tsum tau hnav ntau dua, feem ntau siv quenched thiab tempered steel sawb los yog siab - cov ntaub ntawv muaj zog nrog ntxiv cov ntsiab lus tshwj xeeb alloying los txhim kho qhov ntev - lub sij hawm sharpness ntawm txiav ntug.
4. Yuav ua li cas yog txoj kev loj hlob ntawm steel siv nyob rau hauv kev ua liaj ua teb machinery manufacturing nyob rau hauv xyoo tas los no?
Nyob rau hauv xyoo tas los no, ntau qhov kev pom tseeb tshiab tau tshwm sim hauv kev siv cov hlau hauv cov tshuab ua liaj ua teb. Ua ntej, muaj kev hloov pauv hloov pauv los ntawm kub - dov mus rau txias - dov steel phaj. Npog thiab phaj cov khoom siv rau cov tsheb laij teb loj thiab cov khoom sib xyaw ua ke tam sim no feem ntau yog ua los ntawm cov hlau txias -rolled steel. Thib ob, cov khoom siv phaj yog maj mam hloov cov hlau zoo li qub. Txhawm rau txo qhov hnyav thiab ua kom nruj, ntau lub tshuab ua liaj ua teb ncaj qha yuav cov ntaub ntawv phaj rau txias khoov. Thib peb, kev siv tshwj xeeb hnav-cov khoom tiv taus thiab cov hlau alloy yog nce. Piv txwv li, sib txuas cov hniav yog forged los ntawm 65Mn steel, thiab plowshares feem ntau yog ua los ntawm manganese daim hlau los ntawm txias dabtsi yog khoov. Plaub, lub teeb yuag thiab lub zog siab tau dhau los ua kev tshawb fawb thiab kev txhim kho cov lus qhia. Cov tuam txhab tsim khoom hauv tsev thiab txawv teb chaws tab tom txhim kho ntau dua - lub zog, nyias nyias- dov tshwj xeeb steels kom tau raws li qhov xav tau ntawm kev txuag hluav taws xob, txo qis emissions, thiab kev txhim kho ntsuab hauv cov khoom siv ua liaj ua teb.
5. Dab tsi ntawm cov tshuab ua liaj ua teb yuav tsum xyuam xim rau thaum xaiv cov khoom txias-rolled coil?
Thaum xaiv cov khoom txias-rolled coil, cov chaw tsim khoom siv tshuab ua liaj ua teb raug qhia kom tsom mus rau cov hauv qab no: Ua ntej, cov khoom siv thiab qib sib piv: Xaiv cov qib tsim nyog raws li kev thov tshwj xeeb ntawm cov tshuab ua liaj ua teb. Piv txwv li, DC04 thiab DC06 sib sib zog nqus-kos qib txias- cov ntawv yob tuaj yeem xaiv rau qhov sib sib zog nqus- kos npog qhov chaw, thaum siab- lub zog steel series tuaj yeem xaiv rau siab - lub zog ntawm cov khoom siv. Thib ob, cov khoom siv kho tshuab ua tau raws li cov qauv: Cov neeg siv khoom yuav tsum muab cov ntaub ntawv ua tiav thiab cov ntaub ntawv ntsuas cov cuab yeej cuab tam los xyuas kom meej tias cov ntsuas xws li lub zog tawm los, lub zog tensile, thiab elongation ua tau raws li cov qauv tsim. Thib peb, qhov zoo ntawm qhov chaw thiab kev tswj kev kam rau siab: Agricultural machinery qhov chaw muaj kev xav tau siab rau qhov raug thiab qhov zoo; kev saib xyuas yuav tsum tau them rau lub thickness kam rau ua thiab flatness ntawm txias -rolled coils. Plaub, muab kev ruaj ntseg thiab tus nqi: Kev lag luam tshuab ua liaj ua teb muaj kev thov loj rau cov hlau, xav kom cov neeg muag khoom muaj peev xwm ruaj khov thiab cov nqi sib tw. Thib tsib, tom qab- kev muag khoom thiab kev koom tes hauv kev sib koom tes: High{15}} cov neeg muag khoom zoo tuaj yeem muab kev pabcuam puv - voj voog los ntawm kev sib tham txog kev xaiv cov khoom thiab cov qauv me me -batch sampling mus rau loj- teev cov khoom ncaj qha, thiab tuaj yeem kho cov khoom siv raws li cov kev xav tau tshwj xeeb ntawm kev ua liaj ua teb machinery tuam txhab.
