HP345 tshwj xeeb kub- dov steel coilsyog lub siab -kev ua tau zoo benchmark formanufacturing welded gas cylinders thiab siab hlab ntsha. Raws li tus qauv GB 6653 tus qauv "HP" qhia meej meej hais txog "welding gas cylinders" (los ntawm Suav Pinyinhanjie qiping), thaum "345" qhia nws qhov tsawg kawg nkaus yield zog ntawm 345MPa.
Hais txog qhov kev thov ceev ceev rau cov ntaub ntawv hlau uas muaj lub zog siab, qhov tshwj xeeb zoo sib xws, thiab kev tsim tau zoo heev hauv kev tsim cov roj thooj voos kheej kheej, siab - zoo, tshwj xeeb HP345 kub- dov steel kauj tau tshwm sim los ua ib qho tseem ceeb ntawm cov khoom siv rau kev lag luam niaj hnub roj cylinder.
Nkag siab txog cov ntsiab lus ntawm Cov Khoom Siv thiab Cov Qauv Txheej Txheem ntawm HP345
HP345 yog qib qis- alloy kub- dov steel coil tshwj xeeb tsim los rau cov huab hwm coj- ntau lawm stamping thiab yob- ua cov txheej txheem ntawm lub tog raj kheej roj. Hauv nws lub npe, "HP" sawv cev rau "High Pressure" lossis kos npe rau nws daim ntawv thov tshwj xeeb hauv "Gas Cylinders," thaum "345" qhia txog qhov tsawg kawg nkaus lub zog ntawm 345 MPa (raws li cov kev cai ntawm cov qauv GB/T 14160 thiab ISO 9809-1). Nyob rau hauv cov nqe lus ntawm cov tshuaj muaj pes tsawg leeg, mechanical zog, dimensional tolerances, thiab nto zoo, cov khoom no ho outperforms general-purpose structural steels.
HP345 nruj me ntsis ua raws li cov kev qhia tshwj xeeb rau cov roj kheej kheej tshwj xeeb. Los ntawm micro-alloying tsim (suav nrog ntxiv xws li Nb, V, thiab Ti) thiab Thermomechanical Control Process (TMCP) technology, nws ua tau ib tug microstructure yam ntxwv los ntawm nplua nplej, tsis tshua muaj inclusion theem, thiab siab purity-yog li txaus siab rau cov kev cai nruj rau cov roj cylinder hydrostatic bursting tests, fatty tests.
HP345 High-Quality Tshwj Xeeb Kub-Rolled Coils
Cov txiaj ntsig tseem ceeb ntawm HP345 Steel Coils
High Strength Coupled nrog Zoo Ductility
HP345 nta lub zog tawm ntawm Ntau dua lossis sib npaug ntawm 345 MPa, lub zog tensile xws li 470 txog 630 MPa, thiab elongation (A50) ntawm Ntau dua lossis sib npaug li 24%. Qib no lub zog ua kom ntseeg tau tias lub tog raj kheej roj tswj lawv cov kev tiv thaiv kom tsis txhob deformation nyob rau hauv siab - kev ua haujlwm siab, thaum tib lub sijhawm khaws cia txias txaus-formability margins los tiv thaiv kev tawg lossis ntau dhau lub caij nplooj ntoos hlav thaum lub sij hawm stamping lossis dov txheej txheem.
Superior Suitability rau Stamping thiab Rolling
Gas lub tog raj kheej ntau lawm feem ntau ua raws cov txheej txheem xws li "kub- dov coil → leveling → ncig blanking → sib sib zog nqus nqus / spin forming" los yog "rolled sheet → welding." Nyob rau hauv nws kub-kub lub xeev, HP345 nthuav tawm ib qho kev sib xyaw ntawm cov khoom siv anisotropy piv (Δr tus nqi Tsawg dua lossis sib npaug rau 0.15), uas ua kom yooj yim rau ib qho - kauj ruam tsim ntawm loj - txoj kab uas hla ncig blanks thiab pab txo tus nqi seem.
Cov txiaj ntsig tseem ceeb ntawm HP345 Steel Coils
Siab purity thiab tsawg tsis xws luag
Los ntawm cov txheej txheem cuam tshuam nrog kev ua kom zoo, lub tshuab nqus tsev degassing, thiab electromagnetic stirring, qhov kev ntsuam xyuas tsis yog-hlau inclusions hauv HP345 steel (tshwj xeeb zoo-series inclusions ntawm hom A, B, C, thiab D) yog tswj kom qis dua Qib 1.0, thaum cov sulfur thiab cov ntsiab lus txwv tsis pub tshaj 0% L los yog phosphor 0. Tsawg dua lossis sib npaug li 0.020%, feem. Qhov no tsis tshua muaj cov ntsiab lus suav nrog txo qis qhov kev pheej hmoo ntawm kev ntxhov siab thiab qaug zog tawg hauv cov thooj voos kheej kheej uas raug rau lub voj voog siab.
Uniform Phab ntsa Thickness kam rau ua thiab nto zoo
Tag nrho - dav thickness kam rau ua ntawm HP345 kub- dov coils tuaj yeem tswj tau nyob rau hauv ± 0.10 hli (nyob ntawm seb qhov tshwj xeeb tshwj xeeb). Qhov saum npoo tsis muaj qhov tsis xws luag xws li dov- hauv nplai, khawb, lossis tawv tawv, yog li ua tau raws li qhov yuav tsum tau ua kom nruj rau kev siv vuam txuas txuas ntxiv thiab tiv thaiv- daim ntawv thov txheej txheej.
Txheej Txheem Tsim Optimized rau pawg ntau lawm
Cov txheej txheem tsim khoom rau HP345 tau raug tsim los ua kom haum raws li cov yam ntxwv ntawm kev tsim khoom loj hauv kev lag luam roj cylinder-tshwj xeeb, cov kev xav tau rau "kev ua haujlwm siab, kev siv cov khoom siv tsawg, thiab siab sib xws."
Customized Coil Nyhav thiab Dav:Tus qauv coil hnyav tuaj yeem ncav cuag 25-30 tons, nrog qhov dav ntawm 900 txog 1600 hli. Qhov kev teeb tsa no ua kom yooj yim rau kev ua haujlwm tsis tu ncua ntawm cov kab loj - nplai blanking, yog li txo qhov zaus ntawm coil hloov.
Stable Coil-rau-Coil Performance:Cov txheej txheem siv cov txheej txheem dav dav, kaw- lub voj voog tswj kev ua haujlwm zoo hla tag nrho cov saw hlau ntau lawm (los ntawm steelmaking los ntawm coiling). Qhov no ua kom ntseeg tau tias qhov sib txawv ntawm cov khoom siv kho tshuab- ntsuas thoob plaws lub taub hau, nruab nrab, thiab tus Tsov tus tw ntawm ib kauj ruam - tsis pub tshaj ± 20 MPa.
Weldability thiab Compatibility nrog kev kho cua sov:Cov Carbon Equivalent (CEV) ntawm HP345 yog qhov tseeb tswj nyob rau hauv thaj tsam ntawm 0.38–0.42%, muab kev hloov pauv tau zoo rau ob qho tib si Gas-Shielded Arc Vuam thiab Submerged Arc Vuam. Tsis tas li ntawd, cov khoom siv tswj hwm nws cov qauv kev ruaj ntseg txawm tias tom qab ua haujlwm zoo los yog tempering kev kho mob tom qab kub stamping.
