Thaum xaj cov qauv hlau, cov txheej txheem tsim khoom tau teev tseg yog lub zog muaj zog uas ua rau nws qhov kev ua tau zoo kawg. Rau S335J2WP Corten Steel, ib qho ntawm cov txheej txheem niaj hnub zoo tshaj plaws thiab muaj txiaj ntsig zoo yogThermo-Mechanical Rolling, feem ntau xaiv los ntawm cov lus tom qab"+M"nyob rau hauv tag nrho cov ntaub ntawv hu - tawm (piv txwv li, S335J2WP+M). Cia peb tshawb nrhiav seb txoj kev zoo li cas no ua rau cov hlau tsis muaj zog thiab vim li cas nws tseem ceeb rau koj qhov project.
*(Kev qhia ceev ceev: "P" hauv S335J2WP sawv cev rau "Phosphorus," ib qho tseem ceeb alloying lub caij rau huab cua tsis kam.
Thermo-Mechanical Rolling txheej txheem piav qhia yooj yim
Thermo-Mechanical Rolling (TMR), los yog Thermo-Mechanical Controlled Process (TMCP), yog ib qho kev sib koom ua ke uas cov phaj hlau yog dov los ntawm ib qho tshwj xeeb, tswj qhov kub thiab txias sai. Tsis zoo li normalization (+N), uas koom nrog ib qho kev sib cais re- cua sov lub voj voog, TMR ua tiav nws cov txiaj ntsig hauv qhov txuas ntxiv, lub zog- cov txheej txheem ua haujlwm tau zoo. Qhov no refined tswj kub thiab deformation tsim ib tug superior sab hauv microstructure.
Cov teebmeem tseem ceeb ntawm cov cuab yeej cuab tam
Cov txheej txheem tswj hwm no qhia ntau qhov zoo sib xws rau S335J2WP:
Enhanced Strength & Weight Efficiency:TMR tsim cov qauv zoo dua, tawv dua. Qhov no tso cai rau cov hlau kom tau raws li qhov yuav tsum tau muaj lub zog tsawg kawg nkaus (335 MPa) nrog aqis carbon cov ntsiab luspiv rau ib txwm ua cov hlau. Qhov tshwm sim yog lub zog siab - rau - qhov hnyav piv, ua kom muaj peev xwm siv cov khoom nyias, sib dua yam tsis muaj kev cuam tshuam txog kev thauj khoom - cov kabmob muaj peev xwm.
Superior Low-Tsub Toughness:Lub refined microstructure yog tshwj xeeb tshaj yog zoo ntawm kev txhim kho tej yam toughness. Rau S335J2WP, uas twb tau ntawv pov thawj rau -20℃cuam tshuam tsis kam, TMR txheej txheem tuaj yeem xazoo heev toughness qhov tseem ceeb ntawm txawm qis kub, muab cov npoo ntxiv ntawm kev nyab xeeb rau cov qauv hauv cov huab cua txias.
Txhim kho Weldability:Qhov qis carbon sib npaug (CEV) ua tiav los ntawm TMR yog qhov txiaj ntsig loj rau kev tsim khoom. Nws tseem ceeb heevtxo qhov kev pheej hmoo ntawm vuam -cov teeb meem ntsig txogzoo li txias tawg hauv tshav kub- thaj chaw cuam tshuam (HAZ). Qhov no ua rau welding thicker seem yooj yim dua thiab tuaj yeem txo qhov kev xav tau ntawm kev ua ntej - cua sov, ua kom yooj yim siv.
Kev sib piv & Kev taw qhia
| Yam | Thermo-Mechanically Rolled (+M) | Normalized (+ N) |
|---|---|---|
| Txheej txheem | Tswj dov + ceev cua txias. | Kub- dov, ces rov ua dua thiab maj mam txias. |
| Lub zog tseem ceeb | Zoo heev toughness & weldability; ntau lawm. | Ntau homogeneous zog, zoo tagnrho rau cov seem tuab. |
| Zoo tshaj rau | Cov kev siv niaj hnub no feem ntau, tshwj xeeb tshaj yog qhov uas vuam yog qhov dav lossis qhov hnyav yog qhov tseem ceeb. | Very heavy plates (>25-30mm) los yog qhov twg cov cai tshwj xeeb yuav tsum normalization. |
Yuav xaiv li cas:
Rau feem ntau cov qauv tam sim no-xws li txuas hniav, lub tsev thav duab, thiab cov khoom vaj tsev tsim vaj tsev-S335J2WP+M (Thermo-Mechanically Rolled)yog qhov nyiam thiab feem ntau xaiv kev lag luam. Nws muab ntawv pov thawj huab cua kev ua tau zoo nrog cov txiaj ntsig ntxiv ntawm kev txhim kho weldability thiab lav toughness.
Kev txiav txim siab tseem ceeb:
Yog tias koj tus qauv tsim muajncej-fabrication hot-forming(khoov ntawm qhov kub siab), nrog rau koj tus neeg muag khoom steel. TMR microstructure yog optimized nyob rau hauv nws lub xeev xa, thiab tom qab kub kub tuaj yeem hloov nws cov khoom. Cov hlau tsis zoo (+N) tuaj yeem raug pom zoo rau kev tsim cov txheej txheem nyuaj.
Xaus
Kev qhia tshwj xeeb rau cov thermo-txheej txheem dov (+M) mob rau S335J2WP Corten Steel yog qhov ntse, kev ua tau zoo- tsav xaiv. Nws leverages niaj hnub metallurgy los muab cov khoom uas yogmuaj zog, tshwj xeeb tshaj yog tawv ntawm qhov kub thiab txias, thiab yooj yim rau vuam-tag nrho thaum tuav lub cim, ruaj patina uas txhais Corten steel. Nco ntsoov xyuas koj cov ntaub ntawv pov thawj kom meej meej hais txog kev xa khoom kom lav koj tau txais cov txiaj ntsig kev tsim kho no.
